MicroPython/CircuitPython DOS-like shell for microcontroller boards like the RasPi Pico and Featherwing.
This tutorial is about taking photos using an ESP32-CAM board running MicroPython. The board has an OV2640 without any chip between it and the ESP32. A photo routine and a Webserver were implemented to take a photo using a Webbrowser. MicroPython is a lean and efficient implementation of the Python 3 programming language.
WikiChip is the preeminent resource for computer architectures and semiconductor logic engineering, covering historical and contemporary electronic systems, technologies, and related topics.
How to rig an Arduino up to play a simple melody through a piezo speaker.
This is a thing of beauty.
A wiki of designs, schematics, and links to open source electronics projects. If you get lost in here long enough you'll find some interesting stuff.
A list of tricks and methods for optimizing code written for the ATmel microcontrollers using GNU GCC.
A user-created database of chip and component pinouts. Faster than reading data sheets!
A brief synopsis on the construction of a weapon which can fry RFID chips, including those of passports and ID cards. There are no schematics, just a list of the principles used in the design. You'll need knowledge of electronics to make sense of it and apply them in a practical manner.
A CC-licensed cheatsheet for building with and programming the Arduino.
The SwinSID is a pin-compatible and software-compatible replacement for the Commodore SID chip based upon an Atmega microcontroller. You can drop this chip right into a socket on the motherboard of a damaged Commodore computer, or you can probably drop it into a hardware synth that uses SID chips and hit the ground running. The firmware image and schematics are available for download for free on the website, so you can roll as many of your own as you want.
A technical reference site that has lots of odd information, most of it PC related. Data formats, file extensions, datastructures and algorithms of sundry kinds and uses, hardware specs, microcontrollers, history, advice... there's a lot of stuff buried in here. If you need something you could do worse than check here first.
