Apple2-IO-RPi v5
Terence Boldt Nov 11,2021
Update: There is a v6 but the only difference is a jumper to select internal (Apple expansion bus) vs. external (USB) power.https://github.com/tjboldt/Apple2-IO-RPiPurposeThe purpose of this project is to provide I/O for an Apple II series 8 bit computer via a Raspberry Pi Zero W which is powered by the Apple II expansion bus. This includes using the attached RPi Zero W for it's storage, network and processor to provide new functionality for the Apple II.Project StatusSo far, this is a project a...

Raspberry Pi Pico Radio
Verma Nov 11,2021
Pico radio is a simple raspberry pi pico based FM receiver that uses rda5807m to tune to FM channels. One can listen to these FM channels by attaching an FM antenna in the SMA connector and a 3.5 mm headphone in the audio jack.Hardware build:The hardware is very simple and easy to use. It consists of the following components:an OLED display for showing radiofrequency and FM channel info.a tack switch or push-button for changing channels.a LED for indicating signal strength.You need to surface mo...

Ultra Efficient Raspberry pi UPS
DDL Sep 24,2021
The reason this Uninterrupted Power Supply (UPS) was created was because I wasn't satisfied with the things available on the market that would just lower the incoming voltage to charge the battery and immediately boost it to power the pi. This way efficiencies of around ~80% can be achieved. Don't get me wrong this is not terrible but I wanted to do better, which is why this design incorporates a power MUX.For those who don't know a power MUX is just like a regular MUX but instead of signal line...

Infrared Board
Umm.Engineering Sep 23,2021
This is a reshapening of a typical infrared module with two signigicant changes:The IR-LED and Photodiode positions are swappable by means of bridging solder jumper pads.The design uses a Single *331 comparator rather than a Dual *393 type. This choice was mostly one of OCD.

ISLA Autonomous Robot
Mumba Sep 23,2021
The ISLA Project is a DIY friendly autonomous robot using only mostly through hole components making this design very easy to implement for anyone with some money, a Raspberry Pi Pico and a soldering iron. I decided to make this because I wanted to create something that would be easy to make even for people who do not have access to specific equipment such as a reflow oven, a scope, or a 3D printer. The Design is powered by 4 AAA batteries, which are used to power the various sensors and the mic...

40v raspberry pi voltage regulator hat
Austin Jensen Sep 03,2021
Does your raspberry pi not work when connected straight to your car battery? well it won't work anymore but using this hat you can run a new raspberry pi off of voltages higher than 5v! works up to 40v (that i have tested) which means you can run it off of your car or even truck battery without any fizzling your raspberry pi!if copying please give credit, thanksMade by Austin Jensen 2021

DIY Mini UPS for WiFi Router V5.0
Green Energy Sep 03,2021
The pandemic COVID-19 outbreak forced companies to continue with work-from-home policy to maintain social distancing and for business continuity. More and more of us are working from home these days, and that means your home's WiFi networks are more important than ever.Anyone with a fixed-line connection will know that their WiFi drops whenever the power goes out. It is annoying if you are in an important meeting/webinar through Zoom, WebEx, or MS-Team, and there is an interruption due to power ...
