this is a rebranded project, sorry guys. take your skulls/likes back if you want :) This is supposed to be a generic 555 timer, 4017 decade counter and ULN2004 multiple stage blinking prop board. Every classic science fiction has a prop that blinks. Most of them have four stages. classic 4 stage blinking prop board. Also attiny85 versions to find here and other mcus, this is a blinking things project.
blinking things | boom, starblinken kit is on tindie!
2018-09-06 11:34:11
I've tested and verified my design and put it on tindie btw. :)
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.

blinking things | HT16K33 board for 11x7 LED matrix

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.

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.

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...
