The [MuonPi Project](http://muonpi.org) utilizes an inexpensive Raspberry Pi B+ plug-on module for particle and nuclear physics detectors aimed for measuring muons from atmospheric showers triggered by high energetic cosmic particles. The goal is to set up a distributed network of these detector stations in order to determine the energy, timing, and eventually the origin of the primar...
Updated Design of my Raspberry Pi Doorbell https://www.instructables.com/id/Simple-Raspberry-Pi-Doorbell/
Recomended speakers: https://www.adafruit.com/product/1669
Thanks Adafruit for making your designs open!
This prototype board expands the GPIO pins of the Raspberry Pi to headers numbered like the software (Wiring Pi) uses this. Made for Educational purposes.
Great advantage is that students make less mistakes in the electronic circuit. When they do make a mistake, debugging is much easyer.
You can also use the prototype board in examples of Fritzing:

TinyUPS is a simple 5V/2.5A uninterruptible power supply with a li-ion battery as a buffer, a load sharing power path management system and an ATtiny13 for monitoring power supply and battery charge level as well as for communication with the connected device.
It contains a USB to TTL chip, connect to the Pi UART, you can easily access the terminal; INA219 can help you monitor battery voltage and charge/discharge current; You can mount the SD card reader on your Pi as a NAS; You show some information on the OLED display, such as battery voltage, IP address.

Adopt SW6106 lithium battery charge/discharge IC, support Type-C and Micro-usb power supply, and support charging and discharging.
Dual MCP23017 + GPIO Daisy-chainable IO expander for Raspberry Pi. Uses swappable daughterboards for flexibility, compatible with the common txs0108e level converter boards. See https://easyeda.com/MadOverlord/io-expander-daughterboard for a MIC2981/Passthrough daughterboard, and https://easyeda.com/MadOverlord/io-expander-voltage-divider-daughterboard for a voltage divider daughterboard (for redu...
there is major issue with raspberry pi when it's running and the power is cut
the sd card get dammaged also OS, so it will no be able to run again
and also safe shut down need about 10 second to shut down proprely
