• verified the board design

  davedarko • 07/22/2018 at 14:34 • 0 comments

  I hand wired a combo of NE555, CD4017 and two ULN2003 chips. I also spray painted the protoboard before that. The capacitor I chose is a bit too small, so the animation is a bit too fast. I'll need to grab a 2uF instead of a 1uF cap. Definitely need to add a 100nF cap for the 555 and maybe some more all around. 

  here's a link to it working:

  I've ordered some of CNLohr's RGBY LEDs for my WeMos shield, will update this once they arrive :)

• HT16K33 board arrived

  Board works :)

• HT16K33 board for 11x7 LED matrix

  davedarko • 04/15/2017 at 16:04 • 5 comments

  I recently bought a cool 11x7 matrix, that is just great to display 4 3x5 digits and I want to control it with the well supported HT16K33 - so here's a not so beautiful and highly convoluted board for that.

• 2nd try - this time with SK6812 LEDs

  davedarko • 03/03/2017 at 17:51 • 0 comments

  Definitely mooooaaar white :)

• Got scammed on aliexpress? meh

  davedarko • 03/01/2017 at 11:40 • 7 comments

  So I thought I've bought the new SK6812 with RGBNW on aliexpress.com, but instead I received some standard RGB WS2812 LEDs - not cool :( but the shield works. Now I've bought half of the LEDs for the same price on eBay, let's see how that will turn out ;) dispute on aliexpress was opened, hoping for at least some refund.

  Wemos 2812B moaaaar LEDs shield

  After seeing RGBW LEDs on the Adafruit stream I quickly went on Aliexpress to buy some and then designed a Wemos D1 shield for them, just not with only one LED.

  SMD LED bargraph for breadboards (with Resistors)

  A classic, but I was in the mood to design it.

  RGB LEDs charlie-plexed pinout

  This is basically the layout of one column of a 4x4x4 RGB LED cube...
