Fresh hacks every day
[Jeri's] back with a series of videos that outlines the step-by-step electroluminescent wire manufacturing, making EL panels from PCBs, and assembling power supplies for EL hardware. These concepts are actually quite approachable, something we don’t expect from someone who makes their own integrated circuits at home.
The concept here is that an alternating current traveling through phosphors … Read the rest
[Craig Carmichael] has been hard at work on his electric hub motor for cars. Unlike typical electrical vehicles the plan is to bypass the transmission, differential, and everything else all together by connecting directly to the hub of the wheel. The goal of giving greater thrust and still allowing the use of a gas engine if need be.
There’s … Read the rest
[Jeri Ellsworth] adds electroluminescent wire to the list of things she makes. The materials list is incredibly low. The common components are epoxy coated magnet wire for the center conductor and bare wire for the second conductor. The part you don’t have on hand is phosphors, although she does link to a source.
The bad news: she doesn’t show … Read the rest
[Render] says his coat is simply “enhanced with EL wire”, but we know the truth. He’s secretly an alien that can’t block out all of his glowing green skin with a the black coat. No? Fine,
You can put away the sewing machine, [Render] simply used a needle and fishing line to attach ~50-70 foot of electroluminescent wire to the … Read the rest
[MC] realized he had forgotten about an order for 2000 cut wires that was now due in a few days. Rather than dropping everything to complete the task, he whipped up this machine to cut the wires for him. A PIC 16F628 board drives a couple of battery-powered drill motors. One of them powers two lawnmower wheels for the … Read the rest
Precision CRT manufacture
Here’s a great video from Tektronix about building a precision cathode ray tube. The tube manufacture method was developed to use in oscilloscopes and we’d guess it dates back to the early 1960′s. [Thanks Bill]
Snake on an LED matrix
We would have done a full post o this beautifully built LED matrix but we just … Read the rest
Shortly after finishing his Makiwara punching bag, [Abieneman] wired and programmed an Arduino to an accelerometer to find out just how much acceleration (and with some math, force) is behind his punches. The project is simple and would be quick to reproduce for your own measuring and experiments: all that he used included an Arduino, accelerometer (with A/D converter), … Read the rest
