So here's a late but tenacious Friday post with only 3 but mighty (brand new shiny) products. Not just some… random unrelated strange small bits… But much better! They are all kits. So they have more than one thing in them. Which is better than one thing... How about I stop mumbling the obvious and […]

Our GraviTrack Marble Machine Kit is our newest addition to the Marble-Drop mechanism family. Elegant, swooping hands pass marbles to each other to the top of a sweeping multi-level track, available in either solar or battery configuration! Approximately twice as wide as our spiral Solar or Battery Marble machine kits, the GraviTrack is still desk-top […]

Ok, more like The Northern light. There's only one, but it creates lots of light! We made the SB-Firefly as a ATtiny85-based blinky light / "chewing-gum & duct-tape problem solver", that is also Digispark compatible. We made the Star Controller 3-watt RGB LED kit as an easy way to tame bright and power-hungry LEDs. We […]

Unlike Sparkfun, who actually manage to find fake Atmel ICs, we just get strange batches. The Atmel ATMega328 is the power behind the Arduino/Freeduino/*duino, and we have to set up a programming system to burn the venerable Arduino Bootloader into these chips. We normally use an AVR STK500 in HVSP (high voltage serial programming) mode, […]
