“t’s a foundation for a wearable platform. It’s a Nato watch strap threaded through a PCB with a coin cell battery holder between the PCB and the strap. I’m using a Attiny85 this time around but could …
“The IOT123 BRICKS are DIY modular units that can be mashed up with other IOT123 BRICKS, to add functionality to a node or wearable. They are based on the inch square, double-sided protoboards with interconnected through holes. A number of …
“Create a tiny ATtiny85 controller board that drives some NeoPixels and turn it into laser LED light display. Introduction I had a bunch of ATtiny85 chips laying around and reels of NeoPixel strips, so I decided I wanted to make …

“There are many versions of the ATTINY85 Fuse Resetters on the NET. This is based on the work of Arduino (blog, the above schematic) and Ralph Bacon (GIT, Youtube video above). The main benefit of this device is sacrificing the …
“In developing an OLED ID Tag, I needed to make my design as energy efficient as possible. One approach was to only display the tag if there was someone nearby (think ComiCon or Exhibition booths). The sensors themselves can draw …
“The IR Remote Control Detective decodes the signal from several common types of infrared remote control, such as audio, TV, and hobbyist remote controls. To use it you point a remote control at the receiver and press a key; it …
“This article describes a simple function generator based on an ATtiny85 which allows you to generate a virtually unlimited number of waveforms using additive harmonic synthesis, by specifying the amplitude of each of the waveform’s harmonics: It includes a …
“A reader of my sites and blogs, Mr. Liviu Hinoveanu wanted to replace classical DRL module made with 555 with Attiny85 programmed in Arduino style. He send me the schematic and PCB designed with Livewire and PCB Wisard software: After …
“This small graphics library provides point, line, and character plotting commands for use with an I2C 128x64 OLED display on an ATtiny85 It supports processors with limited RAM by avoiding the need for a display buffer, and works with I2C …
