Homemade Motorcycle Brake Lights
As a motorcyclist, visibility is paramount to the safety of the rider. With this in mind, Pete Mills wired up his own super-bright brake light assembly using bright red LEDs. Not only are the lights powered by the onboard electrical system, but they can be toggled to either stay solid, or blink depending on the rider’s choice. This was done using an ATTiny85 microcontroller.
“The best LED cube build we’ve seen”
And the Hack a Day writers have seen a bunch of them. We’ve covered quite a few, ourselves, and I have to concur that this 8x8x8 RGB from Nick Schulze is the best looking, best designed, and (certainly) best documented LED cube build of the lot. Don’t miss the vid, embedded above, to show off […]
Longboard Generates Light While You Ride
ITP student Danne Woo modified his longboard with strips of LED lights that illuminate when a wheel-mounted generator spins. In short, a stepper motor is run through a bridge rectifier followed by a one farad supercapacitor and then into the LEDs. The resulting project is suitably called “The Circuit Board.”
Challenge: Name This Hack from Wayne & Layne

Ethereal LED “Cathedral” in Belgium
This installation by Italian lighting design firm Luminarie De Cagna was on display in Belfortstraat, Ghent, Belgium, from January 26 to January 29, as part of their 2012 Festival of Lights, where it reportedly stole the show. One can see how it might. The festival site refers to the work as “Cagna Illuminations,” but that […]
Ask MAKE: Modding Vacuum Tubes with LEDs
On today’s Ask MAKE, a reader writes: “I have a box full of old vacuum tubes and would like to do an LED tube mod but I have no clue as to how to wire, power supplies, etc. Could you help me as far the nitty gritty on making this project work?
