Fresh hacks every day
[Martyn] is restoring a 32-year-old Honda motorcycle, so when the ancient speedometer broke last year he thought it was prime time to start of a digital speedometer project. We’re loving the results so far, and would love seeing it on a nicely restored bike.
Instead of the relative horror of driving 40 LEDs with a single Arduino, [Martyn] bit … Read the rest
In the world of model aircraft, Futaba’s SBUS system is a big deal. Instead of having one servo per channel, the SBUS system allows for 16 proportional controls and two digital channels for each receiver. Basically, if you’re building an awesome plane with retracts on the landing gear and bomb bay doors, this is what you want to use. [Michael] … Read the rest
[Martin] sent in a great guide to a simple Arduino based theremin. It’s a very small build – just a single common IC and some passive components – and easy enough to build in an afternoon.
The theremin is based on a simple LC oscillator built around a 7400 quad NAND gate IC, a wire antenna, and a few caps … Read the rest
After years of work, [Junior Veloso] is finally getting his 3D printer project out to the public. Unlike the Makerbots and repraps we usually see, [Junior]‘s printer uses light-curing resin and a DLP projector to build objects with incredibly fine detail.
One highlight of [Junior]‘s project is the development of low-cost resins. Normally, light curing resins are extremely expensive, but … Read the rest
A Remote Sphero-Control Trackball
Sphero is a cool little ball that can roll around under the control of a smartphone. Although super-cool by itself, in this application it’s been hacked into a sort of trackball to drive a remote control car!
Arduino Voice Control
[Sebastian] Wrote in to tell us about this article about using the Arduino EasyVR shield … Read the rest
