It's finally starting to warm up where I live on the 45th parallel, which means it's just about lawn mowing season. It's not a chore I typically enjoy, but this RC lawn mower designed and documented by Terry Creer looks like it might be a kick.

Kalanda sent in this 7x5 dot matrix LED scroller based on the Attiny2313 AVR microcontroller. It looks like a fun little project, but the part I really dug was the way the animation is programmed.

In this Instructable I will show you how to make a flashlight out of an old, 35mm, film canister and some ultra-bright LEDs! You don't need to spend 10$ on a flashlight that isn't even that bright.

CrabFu's latest project, the SwashBot, is a 3-legged radio controlled robot built from RC helicopter guts. The three servos that would normally affect the swashplate control the position of the three legs.

Hi, this is my first instructable so please be kind on the comments, any constructive criticism is very welcome! When i saw the robot competition i was inspired and i decided to modify an old remote-controlled car i had, this instructable shows my process and what i added to the car.

With a couple hours of work, it's pretty simple to pull the power supply from an old PC relic and turn it into a pretty decent bench system for powering your electronics projects.
