Automatic DIY Wire Stripper

Breadboards are a great way to get started with electronics, they can remove the need for soldering which saves time for beginners who are still getting to grips with the basics of electricity, and they allow quick and easy changes to be made without the risk of melting components. However, they do require the stripping of a lot of hook up wires. While these are readily available off-the-shelf, [Stuart] decided a better solution was in order.

The project starts with a set of standard hand-operated wire strippers. A lasercut acrylic frame is then built, with a series of motors and gears to handle the transport of the wire to be stripped and to open and close the jaws of the wire strippers. Wire is fed in, stripped, fed further, stripped again, and then finally cut. The process then begins anew.

The machine is quite pleasant to watch in action, with a series of motors and limit switches helping to control the mechanism. It’s a great way to populate kits that require plenty of hookup wire without having to resort to the more common pressed-on jumper terminals that dominate the post-Arduino era. For context’s sake, this build is from the distant past, circa 2009. Plans to recreate it are available on Thingiverse. Video after the break.

Given this is the future, perhaps you’d prefer your wires laser-stripped instead?

Hot Wire Strippers are Probably The Best Tool You Aren’t Using

I wanted to point out a tool that I often use, but rarely see on other people’s workbenches: thermal strippers. They aren’t cheap, but once you’ve used them, it is hard to go back to stripping wires with an ordinary tool.

I know, I know. When I first heard of such a thing, I thought what you are probably thinking now: maybe for some exotic coated wire, but for regular wire, I just use a pair of diagonal cutters or a mechanical stripper or a razor blade. You can do that, of course, and for large solid wires, you can even get good results. But for handling any kind of wire, regardless of size, you just can’t beat a thermal stripper.

Automated wire cutter and stripper


Kit builder oomlout—we’ve featured their servo bot—needed to produce a lot of precut wires. After cutting and stripping more than their fair share, they decided to apply some heavy engineering to make things easier. They constructed a machine to do the job for them. It has three main components: a servo driven wire feeder to measure the length, a two servo wire stripper that uses an exacto blade, and finally a wire cutter made from snips and a drill motor. The machine is controlled using an Arduino. They’ve published all the plans and code to Thingiverse incase anyone else wants to build a similar machine for their own kit shop. A video of the machine is embedded below.
