  • Election Countown Display
  • Details     from Election Countown Display
  • This display is powered by a wifi-controlled ESP32 WEMOS module.  The specific breakout kit I inherited was a NodeMCU 32-bit module.There are 9x panels in total (or so I'm told, I only 1x on hand) with 9 seperate control signals.The panels all use...

  • Log #89 - CondomBoard specifications
  • Log     from Internet of Condoms
  • Size: about 50x50mm (size of condoms I have, could be a little larger if required)Layers: preferrably a single 2-layer PCB, for easier ordering at the usual suspects in ChinaConnections: debug UARTMicroUSB for charging the batterytemperature sensor connectortwo...

  • Adapter PCB for V1 PCB 010
  • Log     from ARX Hand Project X1
  • Adapter PCB made to accept an Arduino Nano or any similar board to interface with V1 I2C PCB. This reduces the requirements of having to manually wire the connections similar to the photos on V1 hand prototype. Adapter PCB also bring added debugging...

  • Step 3: Firmware
  • Log     from Christmas color light controller
  • The MaTouch ESP32 S3 2.1 Rotary TFT with Touch is not compatible with the TFT_eSPI library, so I use the GFX_Library_of_Arduino library instead of the driver. Since I did not use the TFT_eSPI library, it is needed to delete or comment all the codes related...

  • PCB design decisions: Backlight
  • Log     from RKey
  • I'm not really a fan for RGB, in the {something}-puking-rainbows way, so my first thought was to use single color LEDs. This means I need to create some steady current through a resistor for each N pieces of LEDs. If you want to drive 105 LEDs from a...

  • Details     from ESP8266 RFid reader
  • Get the new boards here, if you want :) ORDER AT aisler.net [15.27 EUR] - ORDER AT OSHpark.com [14.40 USD]Ah shoooot, how could I miss this: http://playground.arduino.cc/Learning/MFRC522 and even this: http://forum.arduino.cc/index.php?topic=199983...

  • Iot Matrix Clock
  • Details     from Iot Matrix Clock
  • I decided to make a beautiful animated (flip) clock with big digits, which is synchronized over the Internet. The basis for my project was the code of Pawel A. Hernik from which I removed the part that shows the weather information and currency rate....

  • How many LEDs ? How fast ?
  • Log     from WizYasep
  • I often get these questions :How many LED can the WizYasep drive ?The answer is : a lot !The W5300 network chip has a 128KB FIFO, that's roughly 40KLED. Is that enough ?Actually I have reduced the receive FIFO depth to 56KB, or about 19K LED. My largest...

  • PT-Clock
  • Details     from PT-Clock
  • Introduction The current time is indicated by the position of the light. The lights are divided into three groups, respectively hours, ten, a fraction, read also more consistent with the habit, several dozens of minutes. The 12-hour system is adopted...

  • The home stretch
  • Log     from Interactive Color LED grid with IR touch sensing
  • (June 2016)I finally decided that the sparkfun level convertor was to blame for the bad clock bits. Yes, I know the clock wasn't even going through the level convertor, but the data was. I removed the PCB with prejudice. As I mentioned before, the shift...
