  • Geiger Counter

  • As you can see from the picture of the testbench for this project, it is buillt in several smaller blocks. I have been building small circuits for a while, as a chance to play with them and learn about better PCB layout techniques. This also results...
  • LoRa AC Dimmer

  • Lora AC Dimmer chopper circuit is based on Triac BT139, and zero-cross checking circuit, it detects the zero-cross points and then the Triac controlled to chop the AC. Besides, to avoid the problem of AC can not be totally shunted off with Triac, a relay...

  • Helium Liquefier

  • Project Goals: Ultimately, the target goals for this project are to be as follows: Keep cost under $5000. Bonus points if the liquefier can be built for less then $2000. This price range allows for local Makerspaces to crowdfund the liquefier. Not only...

  • PS/2 keyboard to keyboard matrix

  • A new github repo was added for the TRS-80 model 3, 4, and 4p:https://github.com/electrickery/ps-2Keyboard2TRS-80. No board is planned, as I don't have a model 3 or 4, so I don't know how the connector looks physically. A modified board did work...
