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!
