Remove the battery pack resistor, install lithium cells Step 1: Remove the top piece of the battery pack. Step 2: Without breaking the switch or battery contacts, carefully cut away the current limiting resistor and LED lead wires.Clip and discard the...
The first step is to get the boards and components. As some of you might be new to ordering custom boards, I quickly walk you through the process. Many of us hobbyists get their boards from dirtypcbs.com and that's where I get mine, too....
As the battery is defintely the most important component of an electric transportation medium, I wanted to create my own to use high end materials and keep the cost low. With 20 Sony VTC6 cells and a BMS you can have a 200Wh (10S2P)...
The one must-have for this project is some kind of 3 axis gantry. In my case, I used a first-gen Wanhau Duplicator i3 printer from roughly 2015. It was a great little machine, but I have plenty of newer printers now. There are a few different controller...
There are plenty of great designs out there, or you can even create your own. Designing your own 3D-printed Raspberry Pi cases can be a fun and rewarding experience. There are a few things to consider when designing your cases, such as the size and shape...
Once you have your design and material, it's time to start printing. You'll need to use a 3D printer, of course, and there are a few things you need to keep in mind. First, you'll need to make sure your printer is properly calibrated. Second, you'll...
Power In to the board:5V via the USB-C connectorDaisy-chained from another Coin Cell Power board via either of the two JST PH 2-pin connectorsInput from any other source (like a lithium-ion battery) via either of the JST PH 2-pin connectorsPower Out...
Step 3: Install the bulkhead fittingThis step is very easy, but it's also your biggest potential leak. Don't worry about that too much now; leak hunting is great sport in the world of vacuum chambers, and there's plenty of time for it later. Find your...
For the EVSE variant only, construct the GFI coil assembly next. Skip this step for the Splitter variant. Place each GFI coil on the table, so that the coil wires are both at the top and both wires are exiting straight up. Take the left wire of each...

Some stoves come with temperature control, but mine didn't. There are dedicated sauna control panels with a timer and temperature control, but they cost upwards of £95. It should be possible to cobble one up myself for less.So I bought this from...
I needed a ubiquitous database that could be accessed by both Python and PHP. It also had to be easy to use with plenty of support, making MySQL the perfect database server. I began by downloading the mysql installer from https://dev.mysql.com/downloads/windows/installer/...
1. Install Node JS (with npm). The process is quite intuitive and there are plenty of tutorials on how to make it2. Download the app here: https://github.com/ultimaterobotics/uECG_nodejs 3. Go to the app folder via command line. For this: - on...
Is air quality data just not enough for you? Well there are plenty of options to add more to your dashboard or stream this data into a weather dashboard you already have!Stream Weather & Air Quality Into a Single Dashboard If you already implemented...
The hardware part of this project is fairly straightforward. The hardest part is probably tracking down a Steel Battalion Controller. Ebay prices as of 2021 show them running north of $300. Admittedly this is probably not a problem as people...
