is this real?

Nope, whoever this person is, they are way off and they have no sources so don’t believe a word they say

In fact Mercedes don’t make their own fuel pumps, let alone McLaren’s. No team has made their own fuel pumps since 2021.

Fuel pumps are categorised as a Standard Supply Component which means that they are designed and manufactured by a third party designated by the FIA.

This means that the same company makes all of the fuel pumps for all of the teams on the grid, so if there was anything going on with a fuel pump they would be going back to this third party not Mercedes.

Just because someone has a blue tick, doesn’t mean that they know what they are saying.

hey guys i need all of us to be insane about electricity real quick

so the stranger things account put on their broadcast channel this video and said “some light reading going on this wednesday”. well i’ve decided to look up each of these books and they all have to do with electricity???? and we know stranger things has an obsession with electricity, so let’s talk about it.

the orange book in the video is “The Voltage Regulator Handbook”. in the introduction it says “Too often, a design finds itself stalled in the development of a power supply to complete the total system. This problem is being eased with the development of a new generation of monolithic integrated circuit regulators and discrete components…” this makes me think of how the upside down is stuck in time and how season 4 ended with the upside down forming into one with hawkins??

then i’m pretty sure the book next to it is “Solid State Lamp” ?? but i googled it and there’s such a thing as solid-state lighting, so the book would be about lights and how they work. that’s interesting to me as lights have been used as a way of communicating with the upside down. also, there’s something called “Solid State Chemistry” as well and that’s interesting because i feel like nancy’s chemistry cards are a clue as to what is going on. i wrote a post about that here

the other book featured in the image is “The Transistor Manual”. another interesting book about electricity, but it seems like it has more to do with telecommunications such as a radio?? the radio has played a significant role in stranger things in regards to music and communicating through a radio.

the blue book is the “Ampex AG-440 AG-445 Recorder and Reproducer Operation Maintenance Manual”. this one intrigued me specifically because of this page??

“CAUTION: DO NOT TOUCH HIM, OR YOU MAY SHARE HIS PREDICAMENT” BITCHHHH WHEN I TELL YOU I SCREAMED???? also you have to keep him warm?? remember the whole “he likes it cold thing?” or the upside down/demogorgon is affected by heat?? my mind can’t help but think is something going to happen to will since he still has a connection with the mindflayer/upiside down/vecna and interacting with him could result in death or harm to oneself ?? LIKE IDK A DAMN THING ABOUT ELECTRICITY EXCEPT THAT THE LAB POSED AS A LIGHT AND ELECTRIC COMPANY, STEVE TALKS ABOUT HAVING ELECTRICITY WITH THE RIGHT PERSON, THE OFFICIAL PLAYLIST FOR MIKE HAS A SONG CALLED “ARE FRIENDS ELECTRIC?”, LIGHTS ARE USED TO COMMUNICATE WITH THE UPSIDE DOWN AND THESE BOOKS ARE CLUES AND SOMEHOW ALL OF THAT LEADS TO BYLER ENDGAME OK THANK YOU FOR BEING INSANE WITH ME ‼️

How NASA saved a camera from 370 million miles away

The mission team of NASA's Jupiter-orbiting Juno spacecraft executed a deep-space move in December 2023 to repair its JunoCam imager to capture photos of the Jovian moon Io. Results from the long-distance save were presented during a technical session on July 16 at the Institute of Electrical and Electronics Engineers Nuclear & Space Radiation Effects Conference in Nashville.

JunoCam is a color, visible-light camera. The optical unit for the camera is located outside a titanium-walled radiation vault, which protects sensitive electronic components for many of Juno's engineering and science instruments.

This is a challenging location because Juno's travels carry it through the most intense planetary radiation fields in the solar system. While mission designers were confident JunoCam could operate through the first eight orbits of Jupiter, no one knew how long the instrument would last after that.

Throughout Juno's first 34 orbits (its prime mission), JunoCam operated normally, returning images the team routinely incorporated into the mission's science papers. Then, during its 47th orbit, the imager began showing hints of radiation damage. By orbit 56, nearly all the images were corrupted.

Long-distance microscopic repair

While the team knew the issue might be tied to radiation, pinpointing what was specifically damaged within JunoCam was difficult from hundreds of millions of miles away. Clues pointed to a damaged voltage regulator that was vital to JunoCam's power supply. With few options for recovery, the team turned to a process called annealing, where a material is heated for a specified period before slowly cooling. Although the process is not well understood, the idea is that heating can reduce defects in the material.

"We knew annealing can sometimes alter a material like silicon at a microscopic level but didn't know if this would fix the damage," said JunoCam imaging engineer Jacob Schaffner of Malin Space Science Systems in San Diego, which designed and developed JunoCam and is part of the team that operates it. "We commanded JunoCam's one heater to raise the camera's temperature to 77 degrees Fahrenheit—much warmer than typical for JunoCam—and waited with bated breath to see the results."

Soon after the annealing process finished, JunoCam began cranking out crisp images for the next several orbits. But Juno was flying deeper and deeper into the heart of Jupiter's radiation fields with each pass. By orbit 55, the imagery had again begun showing problems.

"After orbit 55, our images were full of streaks and noise," said JunoCam instrument lead Michael Ravine of Malin Space Science Systems. "We tried different schemes for processing the images to improve the quality, but nothing worked. With the close encounter of Io bearing down on us in a few weeks, it was Hail Mary time: The only thing left we hadn't tried was to crank JunoCam's heater all the way up and see if more extreme annealing would save us."

Test images sent back to Earth during the annealing showed little improvement in the first week. Then, with the close approach of Io only days away, the images began to improve dramatically. By the time Juno came within 930 miles (1,500 kilometers) of the volcanic moon's surface on Dec. 30, 2023, the images were almost as good as the day the camera launched, capturing detailed views of Io's north polar region that revealed mountain blocks covered in sulfur dioxide frosts rising sharply from the plains and previously uncharted volcanoes with extensive flow fields of lava.

Testing limits

To date, the solar-powered spacecraft has orbited Jupiter 74 times. Recently, the image noise returned during Juno's 74th orbit.

Since first experimenting with JunoCam, the Juno team has applied derivations of this annealing technique to several Juno instruments and engineering subsystems.

"Juno is teaching us how to create and maintain spacecraft tolerant to radiation, providing insights that will benefit satellites in orbit around Earth," said Scott Bolton, Juno's principal investigator from the Southwest Research Institute in San Antonio. "I expect the lessons learned from Juno will be applicable to both defense and commercial satellites as well as other NASA missions."

Why do some people think that their car's headlights aren't bright enough?

The real reasons why people think car lights are not bright enough are complex and multi-dimensional, usually related to physiological limitations, technical misunderstandings, environmental variables and marketing misleading. The following is a professional analysis based on engineering, optics and traffic psychology:

🔍 I. Subjective perception bias (accounting for about 50%)

Age-related visual decline

After 25 years old: Retinal photoreceptors decrease by 0.8% each year, and at the age of 60, the brightness required is 5 times that of a 20-year-old to see the same objects (NHTSA study).

Example: At a speed of 60km/h, a 60-year-old driver's reaction time in low light is 1.3 seconds slower than that of a 30-year-old (equivalent to an additional 22 meters of braking distance).

Contrast deception

The popularity of LED billboards/street lights has led to upgraded ambient light pollution, and the relative brightness of car lights has decreased (such as 300 lux street lights vs. 70 lux car lights).

⚙️ Second, technical cognition misunderstanding (accounting for 30%)

1. Misunderstanding of brightness unit

Parameters Consumer focus Actual impact Lumen value "The higher the better" Beam focusing efficiency is the core (GB4599 requires focus error ≤0.5°) Color temperature "6000K white = bright" Blue light exceeding 6500K will reduce the transmittance by 20% in foggy weather and accelerate visual fatigue

2. Ignore the aging of the optical system

Plastic lens yellowing: The transmittance of headlights over 3 years decreases by 40-60% (UV oxidation + scratches).

Reflector coating peeling off: The high temperature of halogen lamps causes the aluminum layer to powderize, and the light efficiency decays by more than 50%.

3. Wrong upgrade plan

Blindly replace high-wattage bulbs: The original car wiring harness only supports 55W, and using 100W bulbs will result in: → Fuse blown risk ↑300% → Lamp holder melted (case: Volkswagen PQ34 platform wiring harness limit 60W)

🌫️ Three, environmental variable interference (accounting for 15%)

Weather degradation effect Weather Effective illumination distance of headlights attenuated Moderate rain -40% Thick fog -80% Wet road surface reflection Glare increased by 150%

Difference in road materials

Asphalt road reflectivity: 7-10%

Concrete road reflectivity: 25-35% → Cement road is 3 times brighter at the same brightness

📢 Fourth, commercial marketing misleading (accounting for 5%)

Invalid products are rampant

A test on an e-commerce platform shows that 68% of the "300% brighter" LED bulbs actually have a lumen increase of <20% (falsely labeled voltage regulator IC power).

Illegal "laser headlight" modification parts: 90% are actually ordinary LED+light guide tube, which does not meet the GB/T 30036 laser safety standard

KOL test fraud

Common methods used in self-media headlight comparison videos: → The test car deliberately lowers the angle of the original lights → Use color temperature 5000K vs. original 3000K halogen to create the illusion of "whiter = brighter"

💡 Scientific solution

✅ Effective brightness improvement path

Optical system refurbishment

Professional lens polishing and restoration＞95% transmittance (UV coating is required to delay aging)

Replace OEM reflective bowl (e.g. Audi matrix headlight bowl single ￥800)

Compliance upgrade plan Original type Legal upgrade options Brightness increase Halogen reflective OSRAM NIGHT BREAKER LASER/ SH50M +150%/ +700% Halogen lens PHILIPS X-tremeVision GEN2/ SNGL SH70P2 Projector-Specific +130%/ +800% Original LED Replacement assembly at 4S shop (the only legal way) +0%** *Note: Meets ECE R37 standard

Intelligent assistance system

Install thermal imaging night vision device (such as Dongfeng Mengshi commercial version): effective detection distance 300 meters, cost ￥12,000-50,000.

⚠️ Actions that must be avoided

Use >55W bulbs or external power supply with voltage regulator

Modify non-assembly LED/laser modules

Raise the lamp angle to exceed GB4660 standard (low beam <0.7-1.0% inclination)

📊 Cost-benefit analysis

Solution Cost range Actual distance increase Compliance Refurbish lens + upgrade halogen lamp ￥300-800 +40 meters Completely legal Aftermarket LED assembly ￥1500-4000 +60 meters Need to pass inspection Original matrix headlight upgrade ￥8000-30000 +120 meters Completely legal

Ultimate suggestion: When you are dissatisfied with the subjective brightness, first conduct an objective test (measure the low beam illumination distance in a dark area at night, the GB standard should be ≥50 meters). If it meets the standard, the problem is mostly visual decline or environmental interference; if it does not meet the standard, repair the optical system first. Brightness ≠ safety, the beam focusing accuracy is the core - spend ￥50 to do a professional lamp angle calibration, the effect may be far better than ￥2000 modification, or choose an LED bulb with adjustable light type (SNGL) to ensure the beam focusing.

Conditioning vs Regulating: Power Tools for Stage Reliability

In live events and professional AV setups, audio and lighting gear often take center stage—but behind the scenes, power management quietly determines whether everything runs smoothly or fails unexpectedly. Two essential but often misunderstood tools in this realm are power conditioners and voltage regulators. Both serve critical roles, yet they are not interchangeable. Understanding the difference—and knowing when to use each—can protect valuable equipment and ensure seamless stage performance.

Behind every flawless stage performance lies a reliable power infrastructure—complete with conditioners, regulators, and clean cable management.

Understanding the Basics

Power conditioners and voltage regulators are both designed to manage electrical power, but they do so in fundamentally different ways.

Power Conditioners focus on filtering out electrical noise and providing surge protection.

Voltage Regulators ensure that the voltage remains within a stable range, compensating for drops or surges in supply.

At first glance, they might seem like overlapping technologies. However, the situations where each shines are distinct.

What Is a Power Conditioner?

A power conditioner filters and cleans incoming AC power. It removes high-frequency interference, reduces electromagnetic noise, and typically includes built-in surge protection.

Key Functions:

Noise filtration: Removes EMI (electromagnetic interference) and RFI (radio-frequency interference).

Surge suppression: Protects against voltage spikes caused by lightning or grid switching.

Outlet management: Often includes sequenced power-up to prevent inrush current that could damage gear.

When to Use It:

In venues with many dimmers, motors, or nearby radio transmitters.

In older buildings where wiring may introduce line noise.

In digital audio setups where even minor interference can lead to audible artifacts.

What Is a Voltage Regulator?

A voltage regulator stabilizes incoming AC voltage, correcting it in real-time when power fluctuates beyond a safe range.

Key Functions:

Voltage correction: Boosts or reduces voltage to stay within a narrow, pre-defined range (e.g., 110V–125V).

Over/under voltage protection: Prevents damage from brownouts or sustained over-voltage conditions.

Consistent power delivery: Ensures that amplifiers, mixers, and lighting control systems receive steady power.

When to Use It:

In outdoor events or mobile stage setups where power comes from generators.

In rural or industrial areas prone to inconsistent electrical supply.

For equipment sensitive to voltage drops, such as digital consoles and DSPs.

Why Reliability Begins at the Outlet

Many stage issues blamed on “bad gear” or “faulty wiring” are actually due to poor power quality. Amplifiers may clip early, processors can reboot mid-show, or LED walls might glitch—all because of inconsistent power. Integrating the right tool—conditioner, regulator, or both—prevents downtime and protects investments.

Real-World Scenarios

DJ Setup in an Urban Club

City clubs often have tightly packed power systems, neon signs, fridges, HVAC, and lighting all on the same grid. EMI and RFI interference is common. A power conditioner here filters out the noise and ensures that the mixer and controller receive clean power—vital for avoiding buzz, hum, and dropouts.

Outdoor Music Festival

Generators are standard at outdoor festivals. Voltage can swing dramatically depending on the load across stages. A voltage regulator helps by stabilizing power for critical components like digital mixers and wireless microphone receivers. When used alongside a conditioner, it forms a protective barrier against both dirty and unstable power.

Touring Production Rig

Touring racks often combine both technologies. A power conditioner is mounted first to filter and suppress surges. Behind it, a voltage regulator corrects supply variances from venue to venue. This layered approach ensures both clean and consistent power across different environments.

A stage technician configures an integrated power conditioner and amplifier rack, essential for stable power delivery in live performance environments.

Can You Use Both?

Absolutely—and in many professional systems, both are used together. The power conditioner acts as a noise filter and surge suppressor, while the voltage regulator maintains stable voltage levels. Some advanced units even combine both functions in a single rackmount design, though modular setups allow for easier upgrades and diagnostics. If you're unsure which solution suits your needs, consider consulting a professional Audio-Video technician or visiting a specialized pro audio store for tailored advice.

Important Considerations

Line vs. Load Sensing: Choose a voltage regulator that samples line voltage independently, not just the equipment load.

Rack Space vs. Portability: Power conditioners are often compact and rack-friendly. Voltage regulators tend to be heavier due to internal transformers.

Protection Ratings: Look for units with clearly rated surge clamping voltage (e.g., 330V) and response time.

Sequencing Needs: For complex stage systems, look for conditioners with delayed startup sequencing to avoid speaker pop and amp surge.

Placement in Your Signal Chain

Power tools like conditioners and regulators should always come before any audio or lighting gear. Here’s a basic flow:

Wall Power → Voltage Regulator (if needed) → Power Conditioner → Distribution to gear

This ensures that voltage is corrected before it's filtered and safely distributed to sensitive components.

Final Thoughts

Ignoring power quality is like ignoring tire pressure on a sports car—it might not stop the show instantly, but it quietly sabotages performance and longevity. While many invest in premium audio or lighting gear, fewer consider what powers it all.

Choosing between a power conditioner and a voltage regulator isn’t just about technical specs; it’s about understanding your venue, gear, and the conditions in which you operate. In some cases, one may be enough. But for touring acts, large-scale events, or mission-critical audio-video setups, both are essential.

Conclusion:Stage reliability doesn’t start with faders and lighting cues—it starts at the outlet. Whether you’re a DJ playing in a basement bar or managing a festival main stage, the right power tools can make or break the show. Investing in proper conditioning and regulation means investing in consistency, safety, and peace of mind.
