(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...
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...
Sure, you can buy after-market lighting kits. What fun is that?!? … especially for us Arduino-heads :-) If you aren't an Arduino-head, I could be persuaded to put together a kit.. Of course...
For now, CalcHack adds the following hardware:- Complete hardware control over calculator allowing it to be undetectable- Cortex M4 main CPU with Cortex M3 coprocessor- microphone- speaker- 9 axis sensor system (gyro, accelerometer, compass)- 2.4gHz...
This article documented the process of controlling the WS2812B_RGB lamp using the STONE display module. RGB lamp is a kind of lamp that we often see in our daily life. It is widely used, such as: city night scene, light show, indoor lighting, auxiliary...

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...
What you will learn here: Circuit design of small board layout with minimum electronics componentsCircuit assemblyProgramming through ISP and test the complete made device Let's GO! Supplies The required ingredients for producing the earring are as follows:...
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...

I had absolutely no intention of posting this on Hackday. It's a small one-day hack (well, two-day, if you count the time waiting for the epoxy to dry) that piggybacks on all the other blinkylight fun I've had. New code? Nope; I'd already abstracted...
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,...
INS-1 / ИНC-1 Fortunately, these single dot tubes are still easy to find in large quantity and rather cheap. Made by Gazotron, it seems they buildup a large stock at that time. The INS-1 has the advantage to be small and produce a nice dot due...
The goal of this project is to create a versatile robotic platform for robotic competitions. It started with a very primitive PCB design that featured just a few, mostly through-hole components and evolved into a much more complicated design with over...
