Each circuit depicts an original, traced and hand-drawn schematic created by Forrest Mims for his iconic books “Getting Started in Electronics”, and the “Engineers’ Notebook” series. Every board includes a description of how it works, in Mims’ handwriting, on the reverse side.
Alongside the schematic is the circuit itself. Paired with the components you need to build up timeless examples such as the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage Indicator, each board is carefully designed for easy assembly recreating the wonder of learning how electronics work— whether it’s your first soldering project or your fifty-thousandth.
Ever built a quick demo on a breadboard that needed a pot to adjust some parameter? As soon as someone tries to turn it, things come loose. That is, if they even try… little trim pots aren’t very inviting to touch & turn.
This pot adaptor board lets you use real full size (6mm shaft) pots on breadboards. With 10 header pins, the pot mounts securely to the breadboard, even when people turn the knob!
“Hexascroller has been a central fixture at NYCR for the past few years, with a few ups and downs. It’s replacement, Octoscroller, improves on our classic message alert polygon by having two more sides and two more colors of LEDs.”
“interactive art piece built for the NYC Resistor 2014 Interactive Show. It is built with the Octoscroller / LEDscape control board and sixty-four of the 32×16 RGB LED matrices. It has both interactive and non-interactive modes and has been exhibited at many art festivals.”
“Pixel-for-pixel replica of the NYC subway countdown clocks. These tell when the next train will be arriving; my plan is to hook it into the MTA’s real-time data feed so that we can display authentic times for our office and hackerspace.”
