Rewrite code with FastLED + Gamma Correction
Log from SkyLight
Today, i rewrite a code of ambient light of arduino module applied FastLED library carefully. Why? there are 3 important thing, 1) the legacy code of adalight is based on SPI that is used by a RF module too. I think move pin in code of adalight from...

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...

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...

An STM8 eForth WS2812 Demo
Log from eForth for cheap STM8S gadgets
Controlling the WS2812 with STM8 eForth was something I've had on my to-do list for a long time. The lore of W2812 timing is already long and twisted, and any new implementation, it seems, has to add a bit to it :-) Mine is the following: ...

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...

I'd write you a shorter letter if I only had the time.
Log from Holiday Blinkenlights in 1K for about a buck
When you are writing prose, brevity can be difficult. You have to think very carefully about how to express your ideas concisely and achieve maximum impact. Often, it's simply easier to dump the contents of your brain, and just keep writing and writing,...
