Touch sensor using AT42QT1010 with power led indication.
For power led indication, use in conjunction with Delay Timer connected to GPIO14 (https://easyeda.com/lynxlabeling/delaytimer).
Note: this circuit is connected to an N-channel Fet, which pulls GPIO3 pin low when activated. Add 'dtoverlay=gpio-shutdown' to /boot/config.txt file to use. For info, see:

This is a very basic PCB to put a Raspberry Pi Zero into an old sinclair spectrum 48k case...
Code is by a Mr P J Evans and is called ZX Scanner on Github, I've basically made a PCB of his work and added my own hardware parts!
There's a footprint for an RTC this will use generic Pi RTC code
There's a footprint for an Adafruit I2S amplifier board...i've only put this in for those that want to run...
This is a Raspberry Pi Zero W hat/shield with USB MIDI input, stereo audio output, 3 user-configurable buttons and OLED display.
To use as an audio card, enable PWM audio output by adding `dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4` at the end of *config.txt* file.
Remeber that HDMI audio output is the default; use `raspi-config` to force output to 3.5mm audio jack.
If you can't find 47uF...
R-Pi based intercom
Bi directionnal sound video return
IP or 3/4G based (with 3G or 4G hat)
In this version use an audio hat and external speakers and mic for communication.
Add a PI camera with or without infra-red vision to have a visiophone.
Use Jitsi, Wazo or other services to communicate with you devices (phone app, computer app ...) and a pyton script to adress the corect perso...
PoE (Power over Ethernet) to USB 5V adapter.
Current use cases:
- Power micro controllers (Arduino's or Pbpi's)
PoE Switch --> **PoE to USB** --power--> Rbpi
Switch ------------Data----------------> Rbpi (There is still a second Ethernet cable needed for data over cable.)
- Charge your Phone or other USB devices
- Trying to support 802.3af
- Add a way to redirect Ethernet d...
Inspired by N-O-D-E's (Not to be confused with the gaming channel) [Nano Server V2 PCB Bridge](https://n-o-d-e.net/nano_server2.html), my variant is designed to fit on Apple's 5W US Charger and now for the US IKEA Koppla USB charger with a 3D printed enclosure. The reason I designed this PCB is that Node's PCB only fits a specific charging adapter and a specific USB Type A Male plug that I believe...
A board to break out Raspberry PI GPIO into db9 Sega ports and gamecon supported devices
Gamecon and db9 driver rules apply. There's no magic here, just a simple breakout board.
The I2C port is only usable when using just the DB9 ports.
