Electric bikes may be taking the world by storm, but the world itself doesn’t have a single way of regulating ebikes’ use on public roads. Whether or not your ebike is legal to ride on the street or sidewalk where you live depends mostly on… where you live. If you’re …read more

Sometimes a simple idea can yield fantastic results. A few runs of LED strips fastened to a black hoody and sweatpants and just like that…a LED stick person costume for Halloween. The creator of the “Glowy Zoey” [Royce] originally put together some glow in the dark stick person suits to stand out when hitting the slopes at night. Now he’s taken that simple idea for a costume and made a small business out of it.
“I had a lot of extra parts laying around. I gathered everything up and got to work soldering.” – Royce Hutain
The suits themselves consist …read more

Dead-bug circuit building is not a pretty affair, but hey, function over form. We usually make them because we don’t have a copper circuit board available or the duty of making one at home is not worth the efforts and chemical stains.
[Robert Melville and Alaina G. Levine] bring to light a compromise for high-frequency prototypes which uses the typical FR4 blank circuit board, but no etching chemicals. The problem with high-frequency radio is that building a circuit on a breadboard will not work because there is too much added inductance and capacitance from the wiring that will wreak havoc …read more

Electric bikes are getting a lot of attention lately. Pretty much anyone can buy a kit online and get a perfectly street legal ride with plenty of range. But if you don’t want to take the kit route, and you’d rather take a tack that will get you noticed more around these parts, take some notes from [Jule553648]’s recent build that definitely isn’t using any parts from a kit.
The motor from the build is an electric power steering pump from a junkyard car. This gets mounted on a one-off rear bike rack and drives the rear tire with help …read more

If you’ve ever tried to build a printed circuit board from home, you know how much of a pain it can be. There are buckets of acid to lug around, lots of waiting and frustration, and often times the quality of the circuits that can be made traditionally with a home setup isn’t that great in the end. Luckily, [Rich] has come up with a way that eliminates multiple prints and the acid needed for etching.
His process involves using a laser printer (as opposed to an inkjet printer, as is tradition) to get a layer of silver adhesive to …read more
