“For this Instructable we need a WS2812 LED strip, also known as NeoPixel, and any MCU that could be programmed via Arduino. I use Digispark, it is a very nice tiny MCU based on ATtiny85. It has a special bootloader …
“Long time ago, I saw that some drivers in flashlights are using Attiny microcontrollers to deal with different modes. At that time I did not have arduino and I did not know how to program one. Times have changed and …
“A number of people have claimed to make the world’s smallest synthesizer. It’s a pretty silly ambition because at this level the size makes it extremely impractical, and fiddly to pull out of the socket. Nevertheless, I have …
“This instructable show how to use an ATtiny85 to create a tiny watch core that can run over 1 year before recharge or replace battery. The instruction to make the watch case may be in next instructable.”
“The original plan was to just bit bang some mono VGA and do up a Pong or Tetris game, but things went MUCH MUCH further than I ever thought possible, so over the next few weeks I will detail this …
“As I need several battery protectors for my cars and solar systems I had found the commercial ones at $49 to expensive. They also use too much power with 6 mA. I could not find any instructions on the subject …
“An EMF meter can measure AC electromagnetic fields, which are usually emitted from manmade sources such as electrical wiring, while gaussmeters or magnetometers measure DC fields, which occur naturally in Earth’s geomagnetic field and are emitted from other sources …
“In a recent instructable Indigod0g described a mini weather station that works pretty well, using two Arduinos. Maybe not everyone wants to sacrifice 2 Arduinos to get humidity and temperature readings and I commented that it should be possible to …
