“How could something so simple be so useful?”  We heard once that in the 4th millenium B.C. some guy asked the person who invented the wheel that question.  The person who invented the wheel’s answer, we were told, was something like “well it’s not actually that simple - it required engineering and innovation and this thing called mathematics that probably hasn’t been discovered yet and...

These stickers are a must for anyone making a breadboarded Arduino-compatible. They fit right on top of a DIP ATmega328 (or '168) chip, and clearly indicate every pin as it would be called in the Arduino IDE. No more looking up the datasheet or schematic! The stickers are made of a tough vinyl, usually used for bumper stickers, so they will not fade, scratch, or wrinkle. The stickers are die cut already into a rounded rectangle that fits on...

This is a preprogrammed Atmega328P chip, useful if you want to make your own Arduino-compatible or repair a damaged chip on an exisiting Arduino UNO, Duemilanove, Diecimila, or NG! This chip is programmed with 'ADAboot', my version of the bootloader that is "quick-start" NG/diecimila/duemilanove/UNO-compatible. This means that there is still a 5-second delay from when you press the reset button to when the Arduino runs the...

This is a cute half-size breadboard with an assortment of small jumper wires, great for prototyping. Breadboard is 2.2" x 3.4" (5.5 cm x 8.5 cm) with a standard double-strip in the middle and two power rails on both sides. Power rails can be pulled off easily to make the breadboard as thin as 1.4" (3.5cm). The jumper wires are pre-cut and bent in right angles at the ends, so you can choose the appropriate length for your...
