See the Hackaday project page.

Almost the same as v1.6.3, but adds pi network to one output for a 13 dBm into 50 Ω sine port.

I have a 15 MHz Oscillator. My TIA accepts 1, 5 or 10 MHz. This board is a divide-by-3.

  • IC1 & IC2 - dual D flip-flops
  • IC3 - quad 2 input NOR gates
  • C1-3 0.1µF

Inspiration came from here.

This board has the traditional 2 NPN transistor alternating oscillator circuit… but with SMD components to proudly proclaim your achievement!

  • Q1 & Q2 - MMBT3904
  • R1 & R2 - 0805 100Ω
  • R3 & R4 - 0805 100kΩ
  • C1 & C2 - 0805 10µF

And two 0805 LEDs and a CR1220 battery clip.

Hacker's IR remote

Open Hardware / Open Firmware IR joystick.

This board is intended to be powered by a single AA or AAA cell and has a boost converter and an ATTiny45 connected to a 5 direction joystick and an IR LED (the “center” button effectively emulates up and down being pressed simultaneously). The firmware is (will be - pending) open, so you can make it send anything you like.
