Wire Holder

I made a Wire Holder. It’s like a pen holder/pencil cup but for wire of a specific length. It’s difficult to tip it over, especially if you use a high infill. Just visit PrusaPrinters to grab the files for the Wire Holder. (There’s an STL file and an OpenSCAD file available.)

I printed this on my old Monoprice Maker Select Plus, which explains the (poor) print quality. If I had printed it on the Prusa, I’m sure it would look much better. It doesn’t really need to look good though… it works, that’s what matters. (The Prusa was busy printing something more important at the time.)

Also, yes, I know… but this is for wire of a specific length.

PDF to PNGs

Occasionally I need to convert a PDF file to a bunch of PNG files. If you’ve just got one page this is pretty easy to do using Preview.app on macOS. Just open the PDF, export it, choose PNG, choose the desired resolution, and you’re all set. But a multi-page PDF is a bit different, so I’ve got a tool to do it for me.

I’m not going to take much credit for this, as I found the explanation how to do it in some long forgotten forum post and ran with it. It’s basically a macOS Automator Workflow that does all the work. I just packaged it up and tossed it on GitHub as PDF to PNGs

If you find it useful, you’re welcome! If I forgot about it and find this post, congrats to past me!

Solder Spool Holder

I got sick of the old solder spool holder I had not really doing its job. I actually designed a nice laser-cut spool holder years ago at work but alas, I left it there when I moved on. I know you can buy spool holders, and I know you can also make you own, so I made a new one.

This is a chonky spool holder for sure! I really just designed this in about 10 minutes and then hit print before going to bed. It’s a bit more chunky than I expected but I don’t mind much. It’s also not perfect, but it’ll do for now. If I didn’t make this I would have kept using the old crappy one that I’d been using for years.

Here’s what I replaced, which I call the “crappy spool holder” because it’s make from scrap, and I slapped it together in a few minutes, and I’ve had to hot glue it back together after it broke. (I still hate MDF, BTW.)

Subaru Forester

As mentioned previously I got rid of the 2005 Honda Element. It was a great car, and I loved it, but it also broke a lot, and broke more. I finally replaced it with a 2010 Subaru Forester. It’s a smaller car, and it’s different, and I like it, and I’m still getting used to it. It is an all wheel drive vehicle, but it doesn’t seem to have the same handling as the Element. That’s okay. It has heated seats, which is kind of nice. Dana had a Subaru Forester about 15 years ago which is slightly amusing. Anyway, don’t ask me to help you haul large things anymore because I no longer have a large vehicle. Oh well!

Header Pin Snapper

Things have been busy lately. I’ve been building a lot of electronic devices and since there’s soldering and assembly involved I’ve been looking seriously at my tools. In some cases I’ve bought new (and better) tools, and in some cases I’ve looked at making my own tools. Here’s a “Header Pin Snapper” that makes it easy to get a 14 pin header from a longer strip.

I used to use a diagonal cutter to snip the pins to length, and that works fine if you do a few, but if you need to do a bunch a tool is a quick way to do it. I’m not the first to make one of these, you can also check out the Header Snapper – WHSN, the BlueBreaker, this Pin Header Snapping Tool, and a parametric pin header snap fixture, among many others… including the OctoSnap!

So I spent a few minutes making this simple device that can snap pin headers to a length of 14 pins. Exactly what I need, and it works fast. Working fast is often better than working slow. I didn’t need an adjustable one, or a customizable one, so this one fulfills my needs, but might not be useful for others.

It’s just three pieces of 3mm thick acrylic, and four 3mm x 12mm bolts along with four 3mm hex nuts. I’ve got plenty of small scraps of acrylic lying around so made two just in case I misplace one.
