This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

We wondered recently about those crude ASCII schematics you see in some documentation — are there any dedicated schematic-focused tools to draw them, or are they just hand-crafted using vario… ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

All Arduino-compatible boards and extension modules created by Microduino are about the size of a quarter and stackable, which makes it easy to build micro-robotics and other small projects.

The new $49.99 Snapino kit (recommended for ages 12 and up) adds an Arduino UNO circuit board (a tiny but real computer) to the mix, giving Snap Circuits its first true programmability.
