  • Zookeeper
  • Details     from Zookeeper
  • I was discussing with a friend a pet door that would only let out certain animals. We had a few basic ideas (RFID, magnets, etc), but a big issue with a dumb sensor is the wrong animal sneaking out when the door opens. Maybe a camera would work? Sounds...

  • Gigatron TTL microcomputer
  • Details     from Gigatron TTL microcomputer
  • History followed one pathThere were many other waysIt will always be like that Can fewer than 40 old-skool TTL chips implement a multi-megahertz microcomputer with video and sound? This project started as an exploration of what you can build from 30-40...

  • ESPFLIX
  • Details     from ESPFLIX
  • ESPFLIX is designed to run on the ESP32 within the Arduino IDE framework. Like the ESP_8_BIT, the schematic is pretty simple: ----------- | | | 25 |------------------> video out | | | 18 |---/\/\/\/----|---> audio out | | 1k | | | --- | ESP32 | --- 10nf...

  • O Blinkenbaum
  • Details     from O Blinkenbaum
  • I had absolutely no intention of posting this on Hackday. It's a small one-day hack (well, two-day, if you count the time waiting for the epoxy to dry) that piggybacks on all the other blinkylight fun I've had. New code? Nope; I'd already abstracted...

  • Bin Level Monitoring
  • Details     from Bin Level Monitoring
  • The intent is to install the device once and have it be in autonomous service for two or three years. There is not a specific design goal here other than to minimize average power usage, size, and cost. In reality, it will be easier to minimize power...

  • Every year more than 179 million tons of fish are being produced and 156 million tons of that production is used for human consumption. In one way or another, a large portion of the human population is reliant on the fishing industry [1]. To meet the...

  • Smart Knob
  • Details     from Smart Knob
  • System Overview The Smart Knob is based on ESP WROOM 32E microprocessor module. The haptic feedback is realized by burying a BLDC motor in the main body of the knob. A magnetic sensor senses the direction of the knob and sends the angle to ESP32. ESP32...

  • [images and videos are to be reuploaded][Component list will be added soon]Tempo display Since we want a precise time reference, it's better to use a quartz-based oscillator. But, on the other hand, we need to be able to change the oscillator frequency....

  • HB6809 Homebrew computer
  • Details     from HB6809 Homebrew computer
  • I wanted a low cost kit like computer based around the 6809, with a very simple expansion bus. Design goals: Cost - try to keep board footprints small (this was hard, further minimization with surface mount parts would be the way to go even lower)Minimal...
