Raspberry Pi - Project #1: GPIO to Breadboard Breakout
Using the breakout adapter and an old floppy drive cable. The cable is too big by eight holes but the excess can just hang off the end.

Humidity and Temperature Sensor
This is my Honeywell HIH-6130 breakout board populated with components. I tested it and it works perfectly. I only made one, this is a composite photo to show the front and back.

Komodo 3 - inverter circuit

Komodo 3 - inverter circuit
The led on the motherboard’s built-in network interface is normally on and blinks off on activity, I want it the other way round. This is a simple transistor inverter circuit which controls the front mounted LED. Unfortunately the LED resistor is too small and so the LED is much too bright.
