Crimping is referred to as the action of joining wires in a firm bond. The most common use is to terminate (or "cut") a cable at a desired length in order to "crimp" it to a connector. The one you're most likely familiar with is the square bit of plastic that plugs into your computer from an ethernet cable, though there are countless other examples across the networking and electrical engineering world

Joining Forces: The Vital Role of Welding in Battery Production

Whether dealing with square or cylindrical batteries, welding stands as a cornerstone of the manufacturing process. In the intricate dance of lithium-ion battery production, welding techniques are primarily employed in the middle and later stages, where precision and reliability are paramount.

Let's explore some key welding processes that contribute to the creation of safe and efficient batteries:

1. Safeguarding with Explosion-Proof Valve Welding (Safety Vent Welding)

The explosion-proof valve, often called a pressure relief valve, is a critical safety feature. It's a thin-walled component located on the battery's top cover. In the event of excessive internal pressure, this valve is designed to rupture, releasing gas and preventing a catastrophic battery burst.

This valve boasts a clever design, typically involving laser welding two precisely shaped aluminium sheets together. The laser welding process must be meticulously controlled to ensure a reliable seal and consistent rupture pressure. If the weld is too weak or too strong, it can significantly compromise battery safety. Therefore, this process demands extremely precise control over the heat applied.

2. Connecting the Power: Terminal Welding

The battery cover features positive and negative terminals, which serve as the pathways for electrical current. Electrons flow from the active materials within the battery, through foils, tabs, and terminal extensions, ultimately reaching the vehicle's electrical components.

Terminal connections are categorized as internal and external. Internal connections involve welding the battery cell tab to the cover's terminal. External connections involve welding the battery terminal to connecting pieces, forming series or parallel circuits within a battery module.

Typically, the positive terminal is made of aluminium, while the negative terminal is made of copper. A common construction involves riveting followed by full welding. To meet the required tensile strength and conductivity, fibre lasers or composite welding lasers, known for their excellent beam quality and uniform energy distribution, are preferred. These lasers help achieve stable welds in both aluminum-aluminum and copper-copper structures, minimizing spatter and maximizing production yield.

3. Bridging the Gap: Tab Extension Welding

Adapters and flexible connectors are essential components that link the battery cover and the battery cell. These components must withstand high currents, maintain structural integrity, and minimize spatter. Therefore, the welding process must create a sufficiently wide weld while preventing any particles from falling onto the battery cell, which could cause a short circuit. Copper, being a highly reflective material, requires a higher energy density for successful welding.

4. Sealing the Shell: Shell Sealing Welding (Can Sealing Welding)

Power battery shells are typically made of aluminium alloy, with some made of pure aluminium. Stainless steel, particularly 304 stainless steels, is also used due to its excellent laser weldability.

Continuous laser welding of thin-shell lithium-ion batteries significantly boosts efficiency while enhancing appearance and sealing. To achieve even faster welding speeds and a more uniform appearance, many manufacturers are adopting composite welding and annular spot welding, moving away from slower single-fiber welding. In mass production, welding speeds have reached impressive levels, while ensuring weld stability.

5. Securing the Seal: Sealing Nail Welding

Sealing nails, or injection hole caps, come in various forms, often round caps. The welding process must ensure a robust seal capable of withstanding high pressure, free from pinholes, cracks, or explosion points.

As the final step in battery core welding, the yield of sealing pin welding is particularly important. Residual electrolyte can lead to defects like explosion points and pinholes. Minimizing heat input is crucial for suppressing these defects. Laser welding significantly enhances stability and consistency, leading to improved yields.

6. Building Modules and Packs: Module and PACK Welding (Busbar Welding)

A battery module is essentially a combination of lithium-ion cells connected in series and parallel, equipped with individual cell monitoring and management devices. The module's structural design dictates its performance and safety. It must support, secure, and protect the cells while meeting overcurrent requirements, ensuring current uniformity, controlling cell temperature, and providing a means to cut off power in case of severe abnormalities.

Because laser welding copper and aluminium together can create brittle compounds, it is generally used for copper to copper and aluminium to aluminium, in addition to ultrasonic welding. Because copper and aluminium have high laser reflectivity and conduct heat quickly, the connecting piece tends to be thick, requiring higher power lasers.

In Conclusion:

Welding is not merely a joining process in battery production; it's a critical determinant of safety, performance, and longevity. Each welding stage, from the delicate safety vent to the robust module assembly, demands precision and control. The adoption of advanced laser technologies and meticulous process management are essential for achieving high-quality, reliable welds. As battery technology continues to evolve, so too will the welding techniques that underpin its advancement, ensuring safer and more efficient energy storage solutions.

Fiber Optic Adapter - SC Female to SC Female

A Fiber Optic Adapter (also known as a coupler or connector adapter) is a passive device used to connect two optical fibers with the same or compatible connectors. In this case, an SC Female to SC Female adapter would be designed to connect two SC-terminated fiber optic cables together.

Here's a breakdown of the components:

SC Connector: The SC (Subscriber Connector) is a common type of fiber optic connector with a square-shaped snap-in coupling mechanism. It is widely used in data communication and telecommunication networks. The connector has a push-pull design that ensures a secure connection.

Female Connector: The "Female" designation indicates that the connector has a socket or receptor to accept a male connector. In the case of an SC Female connector, it means that the adapter has an SC port with a socket to accept the male end of an SC-terminated fiber optic cable.

SC Female to SC Female Adapter: This adapter is designed to connect two SC-terminated fiber optic cables that have male SC connectors at their ends. Each side of the adapter has an SC Female port (socket) where the SC connectors from the cables can be inserted. This creates a continuous optical connection between the two cables, allowing light signals to pass from one fiber to another.

These adapters are useful in scenarios where you need to extend the length of a fiber optic cable or connect two cables with SC connectors that are too short to reach each other directly. Fiber optic adapters are commonly used in networking, data centers, telecommunications, and other applications where high-speed and reliable data transmission is crucial.

When choosing a fiber optic adapter, it's important to ensure compatibility between the connector types and the mode of the fiber (single-mode or multi-mode) being used. Additionally, make sure to handle and install fiber optic components with care to avoid damage to the delicate optical fibers and connectors.

Senseair K30 CO2 meter Hi, I’ve installed a Senseair K30 CO2 meter to an ESP32 and i’d like to share this with you. Big thanks to martgras and znerk13 for showing the way (Add Senseair K30 CO2 sensor · Issue #1587 · esphome/feature-requests · GitHub). Starting off with the most important question first: why choose the expensive Senseair K30 sensor, and not something else? The choice is based on this scientific publication, which shows the K30 to be a very good sensor. Tomomi Yasuda et al, Comparison of the Characteristics of Small Commercial NDIR CO2 Sensor Models and Development of a Portable CO2 Measurement Device, Sensors 2012, 12, 3641-3655 The result is backup-up by this peer-reviewed paper: Cory R. Martin et al, Evaluation and environmental correction of ambient CO2 measurements from a low-cost NDIR sensor, Atmos. Meas. Tech., 10, 2383–2395, 2017. The result is also backup-up by this non-peer-reviewed paper, which also shows the K30 to be a good sensor: Mengna Li et al, Design of a Calibration System for Miniature Carbon Dioxide Sensors, FLOMEKO 2019, Lisbon, Portugal Okay, based on these results, i choose the Senseair K30. The K30 uses automatic baseline calibration (ABC) to auto-calibrate every 7.5 days. It assumes that lowest measurement in this period is the baseline value of 400 ppm. This mechanism works fine unless somebody is at home all the time (the baseline of 400 would never be reached in those 7.5 days). If the baseline is never reached, it is also possible to disable the ABC-mechanism, but i have not investigated this. Hardware: Power Supply: Mean Well RS-15-5 ESP32: ESP32 WROOM Devkit CO2 sensor: Sensair K30 Bi-directional Logic Level Shifter 3.3v <-> 5v The sensor is very flexible, it can be connected analog and digital via I2C and UART (modbus). I choose UART based on the previous work of martgras and znerk13. Dupont pin headers are soldered onto the Senseair K30 UART terminal. In he picture below, from left to right: ground, 5v, RX, TX From here, the RX and TX go to the Logic Level Shifter → ESP32 TX (GPIO1, orange cable) and RX (GPIO3, yellow cable). As always, RX from the sensor goes to TX of the ESP and TX from the sensor goes to RX of the ESP. Screw the ESP into a project box and fixate the logic level shifter inside. Use a cable gland to fixate cabling in the project box. Now, screw the Senseair K30 outside of the project box, on top of the lid. Make sure to only use two screws, not more. Reason: Senseair advices this to prevent strain on the pcb. Also make sure that both screws are isolated from each other and isolated from main ground (for example by using plastic screws). Connect the wires and screw the top on the project box. CO2 sensors are sensitive to temperature, therefore the ESP32 is inside the box and the sensor is outside of the box attached via spacers. This is also the reason why the power supply is in another location. Building the power supply: this is pretty standard stuff. Crimp ring (or fork-style) connectors to the cables and screw the cables to the power supply. The power supply is placed into a ventilated project box (you can drill holes for this). Make sure to use cable glands to secure the 230v cables, otherwise you are creating a very dangerous situation. Use thick cabling to go from the power supply to the esp32/K30 combination to prevent voltage drop. I’ve used 0.75mm squared cables. You can calculate the required wire thickness using this website: Voltage Drop Calculator Inside the esp32 project box, i’ve placed Wago 221 to divide the cables further into shorter smaller cables to which i crimped dupont connectors (for the ESP32 and the K30) and ferrules (for the Wago 221). End-result of the device. Again, please be aware to place the power supply away from the K30 sensor to prevent warm-up and drifting CO2 measurements. I’ve placed the device inside the ventilation shaft that is extracting air from my living room to the outside. ESPHome is installed onto the ESP32. See the config below. esphome: name: living-room-co2-meter friendly_name: Living Room CO2 Meter comment: ESP32ESP-32S Wroom Devkit v1 + Senseair K30 esp32: board: esp32dev framework: type: arduino # Enable logging logger: baud_rate: 0 # Enable Home Assistant API api: encryption: key: "xxx" ota: password: "yyy" wifi: ssid: !secret wifi_ssid password: !secret wifi_password # Enable fallback hotspot (captive portal) in case wifi connection fails ap: ssid: "Living-Room-Co2-Meter" password: "zzz" captive_portal: uart: id: mod_uart tx_pin: 1 rx_pin: 3 baud_rate: 9600 stop_bits: 1 parity: none modbus: send_wait_time: 200ms uart_id: mod_uart id: mod_bus modbus_controller: - id: sensek30 ## the Modbus device addr address: 0xFE modbus_id: mod_bus command_throttle: 500ms setup_priority: -10 update_interval: 30s sensor: - platform: modbus_controller modbus_controller_id: sensek30 id: status_raw name: "CO2 Status Raw" internal: True address: 0 register_type: "read" value_type: U_WORD accuracy_decimals: 0 - platform: modbus_controller modbus_controller_id: sensek30 id: co2 name: "CO2 Level" address: 3 unit_of_measurement: "ppm" register_type: "read" value_type: U_WORD accuracy_decimals: 0 text_sensor: - platform: template name: "CO2 Status" lambda: |- if (id(status_raw).state == 0) { return {"Ok"}; } if (id(status_raw).state == 1){ return {"Error"}; } else { return "Unknown Code: " + to_string(id(status_raw).state); } The end-result is looking very good. 1 post - 1 participant Read full topic https://community.home-assistant.io/t/senseair-k30-co2-meter/593808

Essay time!

So the main tool that I use to evaluate service priority is an inverse square or gravity model. To calculate, you take the product of the populations and divide them by the distance squared. We'll take the Lowell Commuter rail as our example because it would be the terminus that would extend to Nashua, Manchester, and maybe Concord.

Pop. Lowell: 115k

Pop. Boston: 675k

Distance: 22 Miles*

Gravity Score: 160

We'll use this as our baseline. The units here are gibberish (people^2/sqmi) but we can proportionally compare these numbers to get an approximation of the relative demand. Now, lets add Nashua and Manchester.

Pop. Nashua: 91k

Pop. Boston: 675k

Distance: 34 miles

Gravity Score: 53

Pop. Manchester: 115k

Distance to Boston: 50 miles

Gravity Score: 31 Miles

Now, when we're proportionally comparing these numbers, you can think of them as ratios of estimated trips. For each 160 trips to Lowell, you might reasonably expect 53 to Nashua and 31 to Manchester. That said, we would be potentially looking at a 55% (88/160) increase in riders compared to Lowell.

55% is a lot, but we do have to factor in increased costs. Certain costs are per mile. These per mile costs would increase by 127% (28 new track miles / 22 current track miles) Other costs are fixed or variable in different ways, and I don't have great tools to evaluate them. What I can say is that if this were to be a practical reality, the federal government could also be called on to help as it would be an interstate transportation project to offset some of those costs as well.

But, just with what we have here, lets compare with each other terminal stop on the network.

Needham: 216

Worcester: 86

Providence: 76

Stoughton: 71

Haverhill: 57

Franklin: 38

Scituate: 37

Plymouth: 35

Fall River: 31

New Bedford: 27

Fitchbug/Wachusett: 14**

Rockport & Newburyport: 5&11 ***

The direct comparison here shows in large part why such a service would be consistent with other commuter rail lines. Many of the gravity scores here are lower than what would be expected of a Nashua Connector, and several of these service areas are comparable lengths as well. New Bedford, Worcester, Providence, and Fitchburg all make journeys of close to 50 miles in under two hours on their schedules, matching the distance to Manchester.

There is another thing that the combination of Nashua and Manchester highlights which also is clear in the abnormally low scores for Rockport and Newburyport. On each line, population centers will have mutually reinforcing gravity scores. Beverly, Salem, Swampscott, Lynn and Chelsea all generate trips to Boston but also generate trips to each other, giving the following table.

Now, some of these numbers look a little absurd. How is the 1515 lynn-swampscott score to be read in context? Well, Lynn center and Swampscott center are only a mile away from each other because swampscott is a continuous suburb of Lynn. Therefore, the economic interaction between these two populations is expected to be exponentially higher because of their proximity. A statistically significant number of someones in swampscott aren’t going into boston on a weeknight dinner, but they are going to lynn. When they travel from one to the other, they do it in cars, buses, bikes, and on foot, because the distance is short enough to make all those transit modes viable. Trains realistically make up the smallest part of that 1515 because other modes are more convenient. We don’t need to try to change this. Even setting reductions in driver miles as a goal, buses will solve the problem better than the commuter rail could as a static piece of heavy rail infrastructure. It doesn’t have the dynamic range buses do. The 1515 represents an estimated proportion of economic interactivity that drives and can be used to measure transit demand. So does Rockport’s 5. Even if everyone in rockport leaves rockport on the commuter rail to boston every day, that’s still only 7k people compared to lynn’s 101k and those people are commuting much farther, incentivizing switching to a job with a shorter commute. Nobody likes their 90min commute.

Now, even if we can’t count 100% of those gravity scores as demand for more trains (because more convenient mode shares outweigh trains in practice over small distances), the train still benefits from high trip demand between cities that aren’t the terminus, and many of these city pairs are in fact excellent train connections. Salem-Lynn and Beverly-Lynn score comparably to Boston-Salem and Boston-Beverly, and are in a distance range where walking, biking and buses are less practical, so the train reasonably serves many more people. It’s entirely reasonable to assume that these network effects will also boost ridership for a manchester lowell connection.

When we look at the manchester and Nashua numbers, we get this chart:

These numbers aren’t as high as the north shore, which is to be expected based on the distances, but they’re reasonable compared to the rest of the network shown below.**** The main exception here is Concord. The only score that Concord has above 10 is with Manchester, and it would be the terminus of the line. It’s 20 extra miles of track, almost as long as he initial segment to lowell in the first place. Why would we extend it all that way?

Well, Concord is the capital of New Hampshire. Capital cities drive business traffic in excess of their populations because certain business can only be done there. The gravity model only takes in population and distance, so it can’t reliably assess a variable like that. I like it because it’s fast to calculate and easily comprehensible, but the gravity model is not the best or most sophisticated tool for assessing transit demand. Additionally, if Massachusetts wants to connect population centers in New Hampshire to MA, they would most likely ask New Hamshire to help, and a railroad connecting the capital to its most populous cities would be a project that would mostly benefit New Hampshire. Having them pay for it would be more than reasonable. Then, the actual terminus of the line would be decided by representatives of the actual riders rather than someone in boston. To be clear, I think either terminating in manchester or concord would be reasonable with clear advantages and disadvantages, it just seems like the sort of thing that should be decided democratically by NH itself.

*Geographical distance is substantially shorter than the actual by-car routes, so error in gravity scores should skew actual figures down.

**The abnormally low Gravity score here is partially explained by a large financial contribution from Wachusett mountain resort, which funded an extension of the line to connect to its bus shuttles

***This abnormally low gravity score is because service is extended to Rockport and Newburyport from Salem and the rest of the populous North Shore. Salem alone has a score of 151.

****I’m going to clean up the data because I grabbed numbers fairly sloppily and publish my spreadsheets with consistent population and distance measurements when I get the chance. These are extremely rough numbers with a spur of the moment methodology but the point that they make is worth investigating further. Once I have more consistent numbers I’ll update the numbers in the original post as well.

Why do none of the commuter rail lines extend into New Hampshire? There are two that almost get there but stop short. Don't you care about the people trying to flee the hellhole that is the granite state?

Hey Anon you made me eat my words so hard on this one that I switched to desktop so I could type more

Introducing Wrap030-ATX

New Boards Day!

They're here!

This is a project that has been a long time coming, and something I have wanted to do for a long time.

This is the largest, most complex PCB I have ever designed — a 9.6x9.6 inch (244x244mm) square, 4-layer, complete motherboard for my MC68030 homebrew computer project.

It is designed to support the Motorola MC68030 CPU, MC68882 FPU, two 72-pin SIMM sockets, 512kB ROM, two serial ports, one parallel port, PS/2 keyboard, 4-bpp VGA video, IDE hard drive, and three ISA expansion slots. A complete system all in a microATX form factor.

This builds on my previous work with the 68030, based heavily on my wire-wrap project and the boards that followed. It's a project over four years in the making. I have made a few improvements on the old design, like 16550-compatible serial ports and an updated memory map to support much more RAM in a contiguous space.

Keeping with my existing system designs, I've combined most of the logic into a set of CPLDs. This makes things like PCB layout and logic debugging so much easier. Most of the remaining discrete logic on the board is 74'245 bus transceivers for driving memory and the ISA slots.

I've kept the name "wrap030" in honor of the project's origin as a wire-wrapped prototype, despite the move to proper PCBs. It's just what I've been calling the project in my own head (and design files) all this time, so at this point no other name would feel right.

I of course wasted no time starting to assemble one, but I did stop myself from getting too carried away with the soldering iron. I want to be methodical and test each section before moving on to the next.

I have already found one major error in my board layout — the footprint for the VGA connector is backwards. I may need to bodge together some kind of adapter.

So far I've confirmed the minimalist AT power supply section works with no major shorts on power supply rails, and the reset circuit is working as expected. Next step is to try a free run test with the CPU to ensure the system clock and CPU are working. Once that is confirmed working, I can start loading logic for accessing ROM. My goal is to have it at least running BASIC on a serial terminal by VCFSW in June.

I've forked my existing wrap030 repository on GitHub for this new Wrap030-ATX, since it does make some breaking changes that will require updates to logic and programs. New repo is here:

I have been busy!  These are two new Tritium designs.  Unlike normal glow in the dark Tritium doesn’t need to by charged by an existing light source.  It’s a gas, slightly radioactive (not dangerously so) and glows continuously for 12 to 15 years.  It’s used in high end watches, gun sights - anything that requires constant illumination.  But it’s very, very expensive and is sold in a range of small glass tubes.  For the safety of the tube I install them in a second glass or crystal vial.

The green stick is small 12mm x 2mm.  It’s sealed in the square crystal vial hung on semicircle silver tone connector with pointed terminals.  Two flat struts are used to attach the chain. 

The orange/pink stick is larger 24mm x 2mm sealed within a second glass vial test tube.  I created a hanging bracket for the vial.  The vial is topped with a 5 finned post.  There is a brass ring on the test tube that holds the vial at a midpoint and can be removed.  The vial itself can be worn without the bracket by clipping two clasps to the holes on the top cap that will be included.

Parc Clematis Condo - Prices, Reviews & Property

Occupants will get a free vehicle organization for the underlying 15 months, to a MRT station nearby.And finally, there is a completed extent of 88 workplaces. Something for everyone, whether or not for entertainment or loosening up, or for fitness.As Singapore's unique, and one of its parc clematis balance units  crucial regional focus focuses, Tampines has been shown into a certain business centre.It continues to prosper and create as a point of convergence of business development in the eastern locale. Further, under URA's Master Plan, Tampines remains on course for augmentation and improvements.This will see the progression of significantly more workplaces to address the issues of Tampines occupants, and by chance those of Parc Central Residences too.

In all honesty, Tampines is presently one of the most acclaimed dwelling spaces, given its circumstance between the CBD and Changi Airport. It is pretty autonomous too. There are different adequate estimated malls with burger joints and supermarkets, network library, business environments, sports and swimming structures, retail park, schools, and clear passage by methods for roads or the MRT.Tampines is some different option from a point of convergence of business, or a private area. It is generally given educational establishments up to tertiary level, and overall schools also.

 For instance, the United World College of South East Asia (East Campus) across Tampines Avenue 5, and Temasek Polytechnic around 15 minutes walk around the road.For step by step necessities, there is a line of neighborhood shops close by, at block 872C, a few minutes walk around the essential path of Parc Central EC. It covers an incredibly wide extent of things.

 From a bistro that closes down at 11pm, to a 24-hour Sheng Siong store, a composing material shop, a DIY look for nuclear family items, a confectionary, a laundromat, optician, boutique, and dental and clinical clinics.There are similarly a couple of nature parks in the brief district inside walking distance. The amusement place connector running past the site prompts Bedok Reservoir Park, with Tampines Quarry Park across Tampines Avenue 10.

 The Parc Central pioneer loft suite will benefit by its proximity to Changi Airport as well. Extremely isolated from the solace for those getting flights. The air terminal terminals are a goal in themselves, with their enormous number of eating and retail decisions, not the least of these being JEWEL.The Parc Central Residence EC site is a medium estimated, longish bundle of land. It runs in excess of 260,000 square feet, with expected created zone of around 750,000 square feet.
