A portable breadboard-friendly adjustable power supply, designed as an ideal supply for Arduino projects and other low-power circuits. It provides from 0V to 5.5V at up to 0.5A, and is powered by two rechargable Li-ion cells. The output can be adjusted using a rotary encoder, and the voltage is displayed on a three-digit 7-segment display. The whole circuit is controlled by an ATmega328.

Displays the time by drawing an analogue watch face on a miniature 64x48 OLED display. It uses a separate crystal-controlled low-power RTC chip to keep time to within a few seconds a month, and puts the processor and display to sleep when not showing the time to give a battery life of over a year
