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...

Step 3: Firmware
Log from Lighting Controller With Freely Adjustable WS2812
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...

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: ...

HapticPong
Log from HapticGames
Using the HaptiVision Belt as base we tried out if we can use it also as Display for playing games on it. Of course, with 16*8 pixel that's not high resolution, but we thought that at least games like Pong might work. Adaption was rather easy: Using...

Development of a color table for device calibration
Log from Сolor Identifier for visually impaired people
For the device to work properly, we must calibrate it, because both the parameters of the LEDs in the WS2812, the magnitude of the supply voltage, and the geometry of the holder of light and photo diodes can differ. Ideally, you need to use a ready-made...

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...

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,...

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...

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...

Led Code Used In Example
Log from Teensy v3.1 - FrSky S.Port & WS28xx Led Shield
#include #define PIN 2 //pin 2 on teensy shield #define LEDS 15 //number of leds total // Based on Adafruit Neopixel example https://github.com/adafruit/Adafruit_NeoPixel // Parameter 12 = number of pixels in strip // Parameter 2 = pin number (most are...

Power supply considerations
Log from RGB seven-segment display [RSSD]
A quick primer on powering WS281X LED's There's some important things to keep in mind when designing with Worldsemis WS281X LED's. I'll try to keep it short and concise. Here are the main points to consider: type of LED (there's different versions of...

Hack Chat Transcript, Part 1
Log from Six Months with the ESP32-S2 Hack Chat
OK, big turnout as always when we have our Adafruit friends stop by! I'm Dan, I'll be modding today as we welcome PT, Limor, Scott, Dan and Jeff from Adafruit to talk about both the ESP32-S2 and the new RP2040. Welcome Adafruit people! pt12:00 PMhi...

wow, that thing is bright
Log from DMX NeoPixel Matrix
The prototype is physically built! WOO!Sorry for the crap quality pictures and video, I have a crap smartphone.Hopefully this time, the video works...WOO! that's awesome, huh?So, the gist of it is a 5x5 display... and it's DMX controllable. I explain...
