High Perfects: LRW/SHM Winners!

Our winners this past contest are @bergdg, @deg99 and @wildcardgamez!

@bergdg — Gilt-Leaf Faultless / Safehold Warden

Easy transformation mechanics make for a pretty good time. You have the part of the turn, you've got it as a single-transformation change, and once you read the backside you know what's about to happen. I'll talk about the mechanics secondarily, but the easy switch from Lorwyn's jerk elves to Shadowmoor's preservationists is represented quite well here. It's not even selfish on the front side, just a whole vibe of personal antagonism—and yet, the Warden turns it into a kind of selflessness that makes the Lorwyn elves seem all the stranger. I loved the fact that elves on this plane have a bit of a mean streak. Shadowmoor's elves are equally mysterious and mystical to me, and those motions are represented here with all the mono-green goodness that you can imagine.

Whether or not we get another three-color MTG set on a return plane is something that I can't speak to. The double-hybrid allowing for this to remain mono-green in all its multicolored identity is really cool because you've really mashed together all the things that green can possibly do besides trample, and it works! Not gonna lie, this is a lot of text. All of it groks, but it's still quite a bit, especially with the flavor text. But what the heck, it's done right enough that it's still an awesome way to work up the early grind of beefing the Faultless before the Warden spreads the love. It would for sure make me excited to see some of the counter synergies that one might work up, and I like the gameplay potential of one side building resources and the other side using those resources across the board. Really neat!

@deg99 — Gloryblaze Flamekin / Smoldering Cinders

Hey look, we're using the ol' art contest art! I really love that, actually—Ashling was depicted in one of them, I recall that, and that black-bone Cinder feeling is on point for sure. Also, what a strange and unique card! Mono-redness for the Flamekin checks out, and the disturbance balances mechanically as well. It's odd, but it's possible to put the counters on an opponent's creature and then have that tick down too, which seems... Well, it seems like a niche application but one that's got potential for brewers! Aggressive attacks with your own set of beaters seems like the right plan too. It'll burn out, but that's the point of it. Getting a +3/+3 aura (essentially) for two mana in those colors after your turn-two beater hits the bin? Not insignificant for sure.

I think that the story here is minimal, but this is a bottom-up design that utilizes the worlds of Lorwyn and Shadowmoor to the prompt in a way that I still genuinely appreciate. The front-side Flamekin rushes out, and the flame dwindles because it rushed out too soon. And when it's reduced to cinders, that burning passion becomes hatred, the spite of the Cinders. That flame is snatched up and devoured by whomever claims it. Removal by speed, removal by avarice. It's not necessarily deep and it's not asking to be; the Disturb mirror affects each creature in a similar enough way, just with different frames of mind. I appreciate that a lot! I think both mono-red and Rakdos aggro decks in a standard environment would appreciate this immensely, and I can see how any amount of evasion can stack this up for sure. I think you did a great job here.

@wildcardgamez — Pyrelight Ritualist / Darksmoke Ritualist

The only mechanical wonder I have is the mana-ability-transforming part and the stack, but I suppose that day/night doesn't use the stack in that sense either, so—maybe weirdness is just inherent in transforming DFCs, who'da thought. A 1/1 haster that can ramp you out isn't so strange. The Flamekin have had their share of rituals, and at uncommon for this rate, it's reasonable to see this be not too overpowered. Adding RRRR would be way too much, I think, especially because that would take away from the backside mirror. I love the way that you make the player work for that transformation, because it's both a cool poke into the limited themes, potentially, as well as a fantastic flavor indication of what happens to the Flamekin in the darkness of the Aurora.

The flavor text being mirrored here is absolutely stellar work. You've perfectly encapsulated the feeling of joyous embers to insidious miasma, where the viewer and their relationship to the cards is what matters here. This is the same character in a mirror world, with skills of their other life but none of the same emotions, which is precisely what I was hoping we'd see more of in this contest. The fact that they share the same typeline is really awesome as well. What exists in one world must exist in the other somehow, though not as it first may seem. Yeah, no, I got nothin' else but praise for this execution. Bringing aggro rituals to limited is definitely niche but great for bombs if you can get them off. Bringing this kind of focused worldbuilding is even better.

i wonder if yves has a picture of us as his lockscreen wallpaper... if yes (or no), what picture would it be :0 ?

As much as Yves would love to just... plaster your face on everything he owns, he simply can't and shouldn't.

Yves didn't rise up the ranks by being nice and kind. He rose up by pushing others down. Naturally, he made an army of enemies over the years that would jump at the chance of abusing his weaknesses. It would be much safer to not expose any of his information at all, which sadly includes who he associates with regularly.

His lock screen is just a black background. His gallery contains no trace of you or him. Not even pictures that have accidental reflections of either face. All the metadata from his photos would be expunged.

He does not have any social media applications or games on his phone- not even digital maps. He has his GPS turned off at all times. Yves memorizes his all contact numbers by heart and he never gets a number wrong. His phone is just a slab he used to call or text (sometimes hack into other devices), Yves would delete his call logs, and text messages including yours after documenting all of them in their respective dossiers. When he isn't expecting any communication, his phone is always switched off. Sometimes, he would even remove the battery.

Truly crucial matters will be alerted through the pager hidden in his reliable bag.

That is why you never see him entertaining himself with his smartphone, Yves usually brings a book or a magazine with him. He's living as if he's still in the 80's. If you gave his car a shakedown, you would find atlases and a compass.

But that is just his public phone. He has a few that never leave his office. They're full of you. Videos, pictures, voice recordings, and backups of your messages. One of them is a carbon copy of your current phone, with all the same data you're holding. The other one is an old phone that you sold or lost, one of his precious artifacts of you.

His 'home' phone has pictures of your happiest moments on its lock screen and home screen. It doesn't necessarily have to be photos he took after meeting you. It could be a picture of you graduating high school, it could be a candid picture of you on a vacation trip when you were 8, it could be a picture of your reaction the moment you received your first 'adult' paycheck, it could be a photo of you trying marijuana for the first time, it could even be your baby photos if you weren't that happy in life.

However, phones that store your information aren't usually used as a phone. It just becomes precious data banks. And any evidence that he's spying on you will never be revealed, hence you will never know of its existence.

There is an exception, though. One of his phones is used to analyze what catches your eye on social media. It mirrors your screen in real time, he would record how many seconds you would linger on a post, how many times you rewatched a video, when you would do a double take, your scrolling speed and what exactly would you consume. He would connect the dots and correlate your media consumption habits to the circumstance on that day; would you scroll slower on a cold or hot day? Do you seek out food content if you're hungry or actively avoid it? Why did you rewatch that thirst trap video?

You can go through his phone if you want, but that means he gets to go through yours in return. And you're at a huge disadvantage here because you willingly give up your privacy to him while he gave you nothing. It's not like you have to, he's never on his phone and he's a recluse. What is there to discover?

You know Yves is much older than you are, he used to fuel his past cars with leaded gasoline for god's sake.

So you already expected that at some point along the way, he would comment on this generation's excessive usage of their gadgets. But that oddly never came, because your habits are a treasure trove of information. He would only deride the act if it's actively harming your health.

If you want to put his face on your lock and home screen, go ahead. He would be flattered. Profile picture? Sure. Yves would do some digital magic to make sure the wrong people never see it. As a social media post? Go ahead. Only those whom he knows wouldn't be a threat to you can perceive it.

Of course, just as any paranoid man would do, he would educate you on the dangers of releasing your information to the world. Giving you real-life examples where it could lead to horrifying results. But he would be lying if he said his heart doesn't swell at your willingness to brag about him to your friends.

Obviously, he's also stealing a copy of your lipstick-print-ridden face and printing a physical poster of it to frame in his office. He would openly display it if he obtained it by asking you, but he would hide it if he got the photo by hacking into your phone.

Low Voltage Relays Explained: Types, Functions, and Applications

In the complex world of electrical systems, relays play a crucial role in ensuring safety, efficiency, and automation. Among these, low voltage relays stand out as versatile components that manage and protect circuits operating below 1000 volts. Whether in industrial automation, residential power distribution, or commercial infrastructure, these devices act as the nerve center of electrical control and protection.

In this comprehensive guide, we will break down what low voltage relays are, explore their types, explain their functions, and highlight their diverse applications across industries.

What Are Low Voltage Relays?

A low voltage relay is an electrically operated switch that uses a small control voltage (typically below 1000V AC or DC) to switch larger electrical loads on and off. These relays act as intermediaries between control circuits and power circuits, providing isolation, control, and protection.

Unlike manual switches, relays automate the process of circuit management, responding to electrical signals, fault conditions, or system commands without human intervention.

Types of Low Voltage Relays

Low voltage relays come in several forms, each tailored to specific tasks within an electrical system. Here are the main types:

1. Electromechanical Relays (EMRs)

· Use a coil and a movable armature to open or close contacts.

· Provide physical isolation between input and output.

· Common in traditional control panels and basic automation.

2. Solid-State Relays (SSRs)

· Use semiconductors (like thyristors or triacs) instead of mechanical contacts.

· Offer silent operation, faster switching, and longer lifespan.

· Ideal for high-speed applications and environments requiring low maintenance.

3. Overload Relays

· Specifically designed to protect motors and equipment from sustained overcurrent.

· Available as thermal overload relays (using bimetallic strips) or electronic overload relays (using sensors and processors).

4. Time Delay Relays

Provide a deliberate time lag between the relay receiving a signal and switching.

Used in motor control circuits, lighting systems, and sequential operations.

5. Overcurrent and Short-Circuit Relays

· Detect and react to current exceeding preset thresholds.

· Essential for system protection against faults and overloads.

6. Voltage Monitoring Relays

· Monitor voltage levels and trip when voltages fall below or rise above safe limits.

· Protect sensitive devices from under voltage and overvoltage conditions.

Functions of Low Voltage Relays

Low voltage relays serve multiple vital functions in electrical systems:

1. Switching and Control

Relays control the opening and closing of power circuits in response to low voltage signals from controllers, timers, or sensors. This enables remote and automated control of large electrical loads.

2. Protection

Relays detect abnormal conditions like overloads, overcurrent, under voltage, and phase failures. When such conditions arise, they disconnect the affected circuit to prevent equipment damage or fire hazards.

3. Isolation

They electrically isolate control circuits (usually low voltage, low current) from power circuits (high voltage, high current), ensuring safety and reducing interference.

4. Signal Amplification

A small control signal (from a PLC, sensor, or microcontroller) can trigger a relay to switch much larger loads, effectively amplifying the control power.

5. Automation and Sequencing

In complex systems, relays help sequence operations by ensuring that processes occur in the correct order and at the right time intervals.

Applications of Low Voltage Relays

Low voltage relays are the backbone of automation and protection in various industries. Here are some key application areas:

Industrial Automation

· Control of motors, pumps, conveyor belts, and production lines.

· Use in programmable logic controllers (PLCs) and distributed control systems (DCS).

Power Distribution Systems

· Protect electrical panels from overload and short circuits.

· Monitor voltage and current levels in distribution boards.

Building Automation

· Lighting control systems.

· HVAC (heating, ventilation, and air conditioning) systems.

· Elevator and escalator controls.

Renewable Energy Systems

· Manage and protect solar inverters, battery banks, and wind turbines.

· Automatically disconnect faulty sections to prevent system-wide failures.

Data Centers and IT Infrastructure

· Ensure stable power supply to servers and networking equipment.

· Protect sensitive electronics from voltage fluctuations.

Transportation

· Railways, metros, and automotive applications for control and safety circuits.

Home Appliances

· Found in washing machines, microwave ovens, and HVAC units to automate functions and provide protection.

Advantages of Using Low Voltage Relays

· Enhanced Safety: Isolate control and power circuits, reducing electrical shock risks.

· Automation Ready: Easily integrated into automated systems for smarter operation.

· Cost-Effective Protection: Safeguard expensive equipment from damage due to electrical faults.

· Versatile: Available in many forms to suit different voltage levels, currents, and response times.

· Reduced Maintenance: Especially with solid-state relays, which have no moving parts.

Future Trends: Smart Relays and IoT Integration

As industries move toward smart grids and Industry 4.0, low voltage relays are also evolving:

· Digital relays offer programmable settings, self-testing, and event recording.

· IoT-enabled relays can send status updates and alerts to centralized monitoring systems.

· Energy-efficient designs reduce power consumption while providing reliable protection.

Conclusion

Low voltage relays are indispensable in modern electrical engineering, seamlessly combining protection, control, and automation. From safeguarding your home appliances to managing the power in a sprawling industrial plant, these devices ensure that electrical systems run smoothly and safely.

Understanding the different types, functions, and applications of low voltage relays empowers system designers, engineers, and even DIY enthusiasts to build safer and more efficient electrical setups.

As technology advances, the role of these small but mighty devices will only grow, driving the future of safe, smart, and automated power systems.

The Role of Relays and Timers in Industrial Automation Systems

In the world of industrial automation, efficiency, safety, and precision are crucial. Among the many components that contribute to a well-functioning automated system, relays and timers play a foundational role. These devices act as control elements that manage the flow of electricity, signal processes, and coordinate timing sequences — ensuring that operations run smoothly and safely.

In this article, we’ll explore how relays and timers work, their types, applications in automation systems, and how high-quality products — like those offered by Enza Electric — can enhance performance and reliability in industrial settings.

What Are Relays?

A relay is an electromechanical or electronic switch used to control a circuit by a separate low-power signal or multiple signals. In industrial automation, relays act as a bridge between the control system and the equipment being operated — allowing machines to be turned on or off automatically.

Types of Relays Commonly Used in Automation:

Electromechanical Relays (EMRs): Use physical moving parts; reliable and easy to maintain.

Solid-State Relays (SSRs): No moving parts; faster switching, longer lifespan, and better for high-speed applications.

Thermal Overload Relays: Protect motors and equipment from overheating.

Control Relays: Designed for controlling multiple contacts simultaneously in automation systems.

What Are Timers?

Timers are devices used to delay or repeat electrical signals at predetermined intervals. They help synchronize tasks, automate sequences, and provide controlled outputs over time — critical for complex industrial processes.

Common Timer Functions:

On-delay and off-delay timing

Interval timing

Cyclic or repeat cycle operation

Flashing and sequencing operations

Types of Timers:

Analog Timers: Manual dial settings, simple and cost-effective.

Digital Timers: Offer precise programming, displays, and flexible timing ranges.

Programmable Timers: Ideal for complex automation routines requiring multiple sequences.

Key Roles in Industrial Automation Systems

1. Process Control and Sequencing

Relays and timers enable automated machines to follow a specific sequence — turning motors, lights, or pumps on and off in a logical order. For example, a conveyor system can use a relay-timer combination to control material flow with millisecond precision.

2. Safety and Protection

Relays protect systems by interrupting circuits in case of faults. Combined with timers, they can ensure delay before activating emergency stop functions, preventing false triggers and increasing worker safety.

3. Load Management

In high-demand industrial environments, relays help manage load distribution by selectively energizing or de-energizing machinery. Timers assist in staggered starts, reducing power surges.

4. Energy Efficiency

By automating start/stop functions and managing operation durations, timers help reduce unnecessary energy use. Relays ensure only the necessary loads are powered, minimizing wastage.

5. System Monitoring and Feedback

In smart automation, relays provide feedback signals to the control system. Timers assist with diagnostics by creating intervals for testing or data collection.

Guz, what's the extent of the train systems on your planet? Do they go everywhere? Are there several "lines" that people need to switch between in order to get where they're trying to go? And how far can you get on one train? Like what's the complexity of the system as a whole?

I'm not an expert on the like, logistics side of everything, but as I understand it the vast majority of goods and passengers on Mellanus are moved on rails (accounting for trolleys and trams as well as common carrier railroads). Air travel is used when stuff needs to get somewhere fast, so it displaced mail trains when that got good. Passenger air travel was popular in rich countries before economic standardisation, and some people still fly if they need to get somewhere fast, but air travel has sharply declined since the climate laws got passed. (attempts at nuclear-fission-based zero-emissions planes have never been approved by the relevant regulatory boards, mainly for the safety of the maintenance crew.)

Lots of planets were marked by the scars of personal transportation, but few places on Mellanus have been. Trucking exists for a lot of last mile applications but you'd be surprised just how much stuff moves on cargo trams in cities.

There is a certain irony that Mellanus is so rail-focused compared to our technological peer planets (many of whom aren't even warp capable), and yet our railways are so inefficient--a lot of the trunk lines are still following close by the original migratory foot paths from centuries past, so they're all topsy-turvy with steep grades and sharp curves and stuff like that. There are dedicated high speed right of ways, but they aren't part of like, a global network. I think the reason new electric HSR is being built to United Earth Standard Gauge is because that lays the literal groundwork for regauging the whole planet down the line (or at least standardizing passenger rail).

If you wanted to cross a continent in the north/south direction, you might be able to take a direct express train. It won't be a high speed rail, but you won't have to transload or anything. East/west paths still require a lot of transloading, though some of the more important passenger routes have been dual-gauged or even use convertible-gauge rolling stock.

Also, riding on a train is really nice. They're more comfortable than planes, the really long trips have observation cars and a communal kitchen car with private dining booths, and you don't have to spend hours waiting before you can actually board the train and depart.

The truth is that we're just not really in that much of a hurry most of the time.

“You’re in for it now, fox!” an amplified voice boomed out. “Come out and show yourself!”

Sonic sprang upright, going from asleep to ready-to-fight in moments. “Uh oh. It sounds like Eggman’s out for another fight!”

“Yeah, that’s what it sounds like to me, too!” Tails agreed.

He opened the door to his room, entering the main room where Sonic had been snoozing in front of the TV. “I guess we’d better see what’s going on! Maybe he’s got some evil scheme planned!”

“Evil schemes do seem like his thing!” Sonic agreed. “Let’s get this sorted out!”

“I wonder why he was asking about me, though,” Tails wondered.

Sonic was out of their house first, and he pointed at Eggman’s hovering Egg Calamity. “You’re going down, Eggman! Whatever your evil plan is, I’ll stop it at Sonic speed!”

“Gya ha ha!” Eggman laughed. “You do that, and your friend Mr. Prower will be sorry!”

“What are you threatening, Eggman?” Sonic asked. “You can’t stop me by threatening my friends, I’ll just save them and stop you like every time before!”

“This time, it’s different!” Eggman replied, then his voice got quieter. “Hold on, hold on, I put the script somewhere…”

“It’s there, boss,” a different voice said.

“I knew that!” Eggman griped, as the volume returned to normal. “Ahem! Miles Prower! This is a formal notice from the University of Central City! Your performance will-”

“Oh, I get it!” Tails realized. “Yeah, I should have known that was today!”

He tapped a watch on his wrist, and part of the ground rose up next to the house. It revealed a workshop, twice the size of the house, and a moderately giant robot stomped forwards to stand next to Tails.

“What are you talking about, little buddy?” Sonic asked. “I know this is Eggman so we’re going to beat him, guaranteed, but I usually have a better idea why I’m smacking him around…”

“Oh, please do!” Eggman requested.

“Sorry, Sonic, this is something I have to do myself,” Tails replied, climbing up into the cockpit of his robot, then flicking some switches. Four little mechanical bird robots flew out of hatches on the side, taking up positions to orbit around his main robot, and the whole thing took off as a pair of helicopter blades deployed.

“Aha!” the big man laughed. “Already, you demonstrate your ignorance of the field, Prower! Those airscrew blades might suffice for small distance, short range and low speed applications, but jet engines are far superior!”

“Au contraire!” Tails replied, spooling up the blades. “That’s true for a conventional airscrew, but as you’ll see on page five I’ve developed a novel form of airscrew that retains efficient power transfer up to three times the speed of sound! It’s based on my tails, naturally!”

“Grrrh!” Eggman grumbled. “Well, if that’s the case, then I’m sure you can get out of the way of my Egg Missiles!”

A dozen high-speed missiles flashed out at Tails’s robot, and the robo-flickies darted forwards. Their wings unsheathed to reveal monofilament blades, which diced the projectiles to pieces, and Tails launched his robot upwards in a high-speed jump that avoided the detonating remains of the attack.

Not content with that, Tails slewed his propellers to slide left instead, then right, and finally stopped moving in a hovering position behind Eggman’s Egg Calamity.

“As you can see, the propeller system can more rapidly reverse direction, and provide regenerative braking!” Tails said. “Which is exactly as I outlined on page six!”

“Uh,” Sonic asked, raising his hand.

“You haven’t had the last laugh, Prower!” Eggman seethed, spinning his Egg Calamity through a hundred and eighty degrees. “What about control mechanisms! It would be a shame if you were controlling your defensive drones through something… vulnerable to an electromagnetic pulse!”

The Egg Calamity crackled and fizzed, then detonated a pulse of electricity. Tails’s robot also fired out a pulse of electricity, negating the EMP Eggman had launched, and the flickies flew into a protective position between the two battle machines.

“Phase-inverted pulse protection!” Tails said proudly. “It’s not just an EMP generator built into the Dissertailstion, but it’s also-”

“You called it a what?” Eggman asked.

“Okay, okay, time out!” Sonic demanded. “What’s going on here?”

“He doesn’t know?” Eggman said, sounding baffled.

“Hey, cut him some slack!” Tails replied. “He’s not done much school… right, Sonic? I’m pretty sure I’d have remembered you doing a university course.”

Sonic began to protest, then remembered that both the other people in the conversation were the smartest people on the planet.

“Yeah, if this is a college thing I wouldn’t know,” he replied. “So what is it, then?”

“It’s simple!” Tails said. “I’m trying to get my degree in Advanced Super Technical Robotics, but I failed to anticipate ahead of time that the only other person on the planet able to evaluate my work was Dr. Ivo Robotnik!”

“Robotnik?” Sonic repeated. “Is that his real name?”

He snorted. “Wow. You mean Eggman was a choice?”

“Insolent hedgehog!” Eggman seethed.

“But that still doesn’t explain anything!” Sonic added. “Why did he turn up to fight you, and why can’t I help?”

Tails shrugged. “You can’t get someone else to help with your thesis defence.”

Why are the headlights on race cars tinted yellow?

The yellow color design of racing headlights is based on the comprehensive consideration of performance optimization, regulatory tradition and visual recognition. The following is a detailed analysis:

1. Improve optical performance in bad weather

Physical advantages of yellow light:

Wavelength range: Yellow light (about 580-590nm) has a longer wavelength than white light (400-700nm full spectrum), has a low scattering rate in rain, fog or dusty environments, and has a penetration increase of about 30% (according to the French National Meteorological Service).

Contrast enhancement: Yellow light is more easily recognized by human retinal cones in low visibility conditions (peak response of bright vision is 555nm), helping drivers to identify track edges and obstacles faster.

Practical application:

Le Mans 24 Hours: Morning fog is often encountered in night stages. Yellow light can penetrate the mist 300 meters away, while white light can only cover about 200 meters.

Rally (such as WRC): Headlights need to penetrate the dust and sand, and yellow light filters (such as Osram Yellow Boost) can extend the effective lighting distance to more than 500 meters.

2. Historical traditions and competition rules

French regulatory heritage:

In 1936, the French government required civilian vehicles to use amber lights to reduce glare for oncoming drivers. This regulation influenced early racing car designs (such as the Bugatti Type 57G Tank).

Although the regulation was abolished in 1993, events such as Le Mans still retain yellow light as a cultural symbol.

Mandatory requirements of competition rules:

FIA GT3: Some tracks (such as Spa-Francorchamps) require participating vehicles to use yellow auxiliary lights in rain battles (compliant models such as HELLA Rallye 4000 Yellow).

Dakar Rally: mandatory headlights must pass IP6K9K dustproof certification, and yellow light filters can reduce visual fatigue caused by dust reflection.

3. Brand identity and visual strategy

Iconic design language:

Porsche: From 917K to the current 911 RSR, yellow headlights (with green body) have become a classic element of Le Mans' "Gulf paint", enhancing brand recognition.

Toyota Gazoo Racing: TS050 Hybrid headlights use amber LEDs, which form a high contrast with the red body, making it easier for media cameras to track.

Psychological suggestion:

Yellow light conveys "aggression" and "speed", which is in line with the visual aesthetics of racing sports (refer to Pantone color psychology research).

4. Technology Evolution and Modern Alternatives

Filters vs. Native Yellow LEDs:

Traditional racing cars use coated glass filters (such as Plexiglas AMC yellow models), which cost about $50/piece and have a transmittance of 92%.

Modern solutions use custom spectrum LEDs (such as Cree XP-L2 580nm chips), which reduce energy consumption by 40% and have a lifespan of 10,000 hours.

Adaptive lighting technology:

Some LMDh prototypes (such as the Audi R18) are equipped with intelligent systems that can dynamically switch between yellow/white light modes:

Sunny day: White light (6500K) provides maximum illumination (120,000 lumens).

Rain and fog: Switch to yellow light (3000K) to reduce reflected glare.

5. Controversy and exceptions

Opposing viewpoints:

Some studies (such as the MIT 2022 report) point out that yellow light is inferior to white light in color rendering on dry nighttime tracks, which may obscure details (such as oil stains on the road).

Some events (such as NASCAR) prohibit yellow headlights to simplify technical standards due to closed tracks and no complex weather.

Alternative solution examples:

Formula E: All-electric racing cars use blue light strips (symbolizing clean energy) and abandon function-oriented yellow light.

Conclusion: Racing yellow headlights are a fusion of performance requirements, historical precipitation and brand aesthetics. Although modern technology provides a better option, its advantages in rain and fog penetration and cultural identity still make it irreplaceable on the track.

What is a Transceiver in a Data Center? | Fibrecross

A transceiver in a data center is a device that combines the functions of transmitting and receiving data signals, playing a critical role in the networking infrastructure. Data centers are facilities that house servers, storage systems, and networking equipment to manage and process large amounts of data. To enable communication between these devices and with external networks, transceivers are used in networking equipment such as switches, routers, and servers.

Function and Purpose

Transceivers serve as the interface between networking devices and the physical medium over which data is transmitted, such as fiber optic cables or copper cables. They convert electrical signals from the equipment into optical signals for fiber optic transmission, or they adapt signals for copper-based connections, depending on the type of transceiver and network requirements.

Types of Transceivers

In data centers, transceivers come in various forms, including:

SFP (Small Form-factor Pluggable): Commonly used for 1G or 10G Ethernet connections.

QSFP (Quad Small Form-factor Pluggable): Supports higher speeds like 40G or 100G, ideal for modern data centers with high bandwidth demands.

CFP (C Form-factor Pluggable): Used for very high-speed applications, such as 100G and beyond.

These pluggable modules allow flexibility, as they can be swapped or upgraded to support different speeds, protocols (e.g., Ethernet, Fibre Channel), or media types without replacing the entire networking device.

Importance in Data Centers

Transceivers are essential for establishing physical layer connectivity—the foundation of data communication in a data center. They ensure reliable, high-speed data transfer between servers, storage systems, and external networks, which is vital for applications like cloud computing, web hosting, and data processing. In modern data centers, where scalability and performance are key, transceivers are designed to meet stringent requirements for speed, reliability, and energy efficiency.

Conclusion

In summary, a transceiver in a data center is a device that transmits and receives data signals in networking equipment, enabling communication over various network connections like fiber optics or copper cables. It is a fundamental component that supports the data center’s ability to process and share information efficiently.

Regarding the second part of the query about Tumblr blogs, it appears unrelated to the concept of a transceiver in a data center and may be a mistake or a separate statement. If you meant to ask something different, please clarify!

MCACN Class of 1965 Sponsored by Garner Customs

ONE of ONE 1965 COPO CHEVELLE 300

Owners: Mike and Dot Smith, Cookeville, TN

Central Office Production Order - COPO 9719 verified by Tonawanda engine manufacturer’s data, Chevrolet Division COPO team member Jim Mattison along with Floyd Garrett and Mark Meekins.

Special thanks to: Doug Garrett who restored the car Floyd Garrett who recommended Doug and encouraged me to restore the car. Bob Vance who was responsible for the discovery of the car. Mark Meekins who found the documentation of the car and wrote about it. Jim Mattison – Member of Chevrolet COPO group that validated the car and sent Floyd Garrett copies of the Tonawanda engine manufacturer’s documents showing the COPO number for the ONE 396/425 engine built for a Chevelle 300 application (Revised in July 1965 to show this engine). The same COPO number 9719 appear on my window sticker. Dewayne and Mike Lemonds –Paint and body work. Eddie Kantor for having the car made and selling it to me.

History of how car was made. Eddie Kantor (Fast Eddie), who worked in the Pontiac Motor division of GM, had been receiving the latest power equipment from Bunkie Knudsen. Eddie raced Pontiacs in the late 50s and early 60s. When Knudsen switched over to Chevrolet, Eddie with his connections ordered this unique Chevelle 300 under the Central Office Production Order (COPO).

Special Equipment: Ordered and delivered to Floyd Foren Chevrolet (a dealer for special COPO cars) 396 Cubic Inch engine 425 horse power engine with transistorized ignition (better and more uniform spark at high rpms). Solid lifters with the camshaft the same as the 425 hp Impalas and Corvettes. Special radiator, special two piece riveted wheels 14in X 6in Gold line tires (Original spare is in the trunk) M22 Rock Crusher transmission (32 of these made it into production cars) All 1965 M22 (Rock crusher) transmissions were made April 15, 1965. Rear Differential 4.88:1 posi-traction (The Z16s were 3.31:1 open chamber) Boxed Frame and heavier sway bars to handle the increased torque of the 425 hp engine. Larger 11 inch drum brakes for additional stopping power but no power assist. The Chevelle 300 was ordered due to the lighter weight (Over 200 pounds lighter than the Z16s. Radio delete, but it does have a heater. In addition to the go fast parts the only other option was a two speed wiper motor. No power steering, No power brakes. (Additional weight not needed for going fast) No exterior rear view mirrors. What ever is behind you is of no consequence especially on Woodward Avenue, Detroit Michigan where this car was raced between the stop lights.

History of my ownership of car. Eddie Kantor retired from General Motors in the late 60’s, and moved his family, wife Dimple (My cousin) his daughters Linda and Shirley to Cookeville, TN.

I worked for Eddie after school and on weekends in his speed shop. When I was a senior in high school I was looking for a car that I could buy so I could have my own transportation. Eddie had this Chevelle and I bought the car from him in November 1968 and have owned it ever since. When I purchased the car, Eddie handed me the window sticker and said for me to hold on to it, which I did. I was 17 at the time and it just didn’t seem to be important at that moment. My wife and I dated in this car and we eventually drove it on our honeymoon in December, 1970.

How this ONE of ONE car was discovered One day as I passed by my friend’s (Bob Vance) office, I noticed a picture of his car on the wall. It was a 1966 Chevelle 300 deluxe. I told him of my 1965 Chevelle 300 that was ordered with the 396/425hp engine, M22 -4 speed transmission and the 4.88:1 positive traction rear end. Bob would later tell me that he knew I would not lie to him but he thought I was greatly mistaken on what I had. One week later Bob was reading in the National Chevelle Owners Association magazine an article where someone had asked about the number of Z16s that had been made. Mark Meekins answered the question and in the closing sentence mentioned that, oh by the way, there was one 396 cu in 425 hp engine built for a 1965 Chevelle 300 application. He also said the fate of this car is unknown. Bob Vance immediately called Mark Meekins and soon Mark was talking with me on the phone. Mark asked about some of the features on my car and I explained the frame was boxed in, brake line on the passenger side passed along the outside of the frame away from the exhaust manifold. The radiator had a center fill spout and the wheels were two piece riveted with gold line tires. Mark’s next question was, “I need directions to your house���. After the drive from North Carolina to Cookeville, TN, in Jackson County and after a thorough inspection Mark opened up his article in his magazine about the special Chevelle 300 and pointing to my car said, “That is it”.

You are looking at the only GM Factory made 1965 Chevelle 300 COPO 9719 made for having fun on the streets of Woodward Avenue, Detroit Michigan
