  • Log     from Ignore this ESP8266 board
  • When "designing" [stealing] this board parallel to the talk for the #ESP8266-01 Breakout I placed an LD1117AS33TR in my schematics while Matt used an LM1117 on his board. At this time I was only looking for a 1117 in the eagle library and added it. Turns...

  • Neopixel Wifi Clock
  • Instructions     from Neopixel Wifi Clock
  • Get the parts first. Print out the CAD models, the base and the top clock face. We used white ABS since it has excellent colour translucency. The LED rings were fitted first, then the pixels at 12 position were aligned. Hot glue was used to hold it in...

  • Making the main board
  • Log     from A Spring-Drive Digital Movie Camera
  • Now that we are able to detect the shutter movement, which had been a pending project, we have started fabrication of the main board.It has a DC-DC converter, a photo sensor for shutter detection, DIP switches for inputting shooting conditions, and pins...

  • The hardware
  • Log     from Numican
  • The clock is based on an STM32F042 microcontroller for several reasons: It's in a small but still hand solderable package, ssop20. It has enough IO's for this project It has a build in USB bootloader, so no USB to serial converters or programmers needed.It...
