Fresh hacks every day
We’ve seen our fair share of Tron costumes and props, but much like [Sean-h] points out, they are usually pretty bulky and baggy. He’s gone a slightly different route by starting with a wetsuit instead of bulkier items like leather jackets. The lighting is done in the same manner we’ve seen before, copious amounts of EL wire and EL tape. … Read the rest
We’ve seen a lot of builds using electroluminescent wire, usually in the realm of costumes and props. Unfortunately, most electrical engineers don’t deal with blinking and dimming EL wire and panels and any tinkerer trying to control electroluminescence doesn’t have a lot of resources on how to control EL stuff. [ch00f] wanted to fill this knowledge gap, so he build … Read the rest
If you’ve been putting off that reupholstering project here’s a little incentive to get started. Adafruit now has some electroluminescent wire which is perfect for use as piping. They’ve outfitted a small sofa with the glowing material and we think it looks great whether switched on or not.
The installation process is really quite easy. The EL wire is covered … Read the rest
Although many might not know it, electroluminescent materials use high voltage, and thus qualify for our featured topic. Many may assume that these sheets work in the same way as LED lights, using low-voltage DC power. This, however, is not the case, as they need around 100 volts of AC current to allow them to light up.
For a battery-powered … Read the rest
All EL wire drivers use a resonator circuit to supply power to the EL wire. It’s an efficient system, but [Paul] noticed that there was some color change when powering different lengths of wire off of the same driver. He realized that this is because of the changing frequency of the resonator circuit, so the only reasonable thing for [Paul] … Read the rest
Get your graphite and hike a wheel, [Aron Hoekstra] writes in to completely embarrass us with some excellent pinewood derby cars. In the pursuit of that extra something [Aron] consulted with his sons who came up with some cool ideas for cars, one Tron themed and the other basically a Wiimote with wheels! The official Pinewood derby rules say … Read the rest
Yep, these cereal boxes light up. They’re using a new branded-technology called eCoupling that provides electricity via induction, which means the shelves have a coil with AC power running through it. The “printed coils” on the boxes allow inventory control and data exchange presumably thanks to a low-power microcontroller. But in the video after the break you can … Read the rest
