Happy Shiny Bolts


When you buy a bolt, it doesn’t typically have a nice flat head on it. It’s got a bunch of markings, and usually some sort of part number, or something. Here’s a bolt I found on eBay. Look at all those numbers and letters!

Here’s a close-up I shot of a bolt head. What does it all mean? Well, Brant told me that the manufacturers add these markings to help prevent counterfeit parts. He even mentioned that years ago a building was built with some knock-off fasteners and it collapsed causing terrible damage. Terrible!

Well, I brought a bolt to the makerspace because I wanted it to have a nice smooth and shiny top. Bill**2 was kind enough to show me the new metal buffing area, which has a nice belt sander (which we used to remove the lettering) and 6 (yes, six!) buffing wheels of various grit. I used all six to give my bolt a nice clean shine.

Here’s my bolt after removing the letters and buffing it up. I probably could have done a bit more, but this was still a hundred times better than before I started. And yes, it is hooked up to an AT42QT1010 Capacitive Touch Breakout Board and a Teensy.

Camera Accessory Mounting System

CAMS pieces

Those who know me know that besides being cheap (hey, it’s part of being a maker and being DIY) I tend to use cameras a lot. Well, on occasion camera related things break, or I’ll need a part that doesn’t exist yet, or exists, but it too expensive, or isn’t designed right, or whatever.

All of the issues mentioned above lead me to create “CAMS” the “Camera Accessory Mounting System”, which will be a modular system that allows me to mount things to cameras, and mount cameras to things.

The connecting pieces of CAMS are 3D printed, and design is happening in OpenSCAD. The other parts of CAMS consists of standard 1/4″ hardware, nuts, bolts, screws, etc. There are also knobs that fit onto the nuts to allow for easy finger tightening.


There’s a wiki page for CAMS, which doesn’t have a ton of info yet, but you can also check out blog post #1 and blog post #2 about the arm.
