Bike Light GoPro Mount Adapter

Here’s another quick and practical project that I knocked off in a couple evenings.  My new POC mountain bike helmet has a non-standard venting arrangement, which makes it tricky to mount most bike lights that use Velcro straps.  However, I had mounted one of the adhesive GoPro camera mounts to shoot some video footage a ...

Bicycle Disc Brake Caliper Mount

It’s no secret that I can get pretty wrapped up in projects.  Witness a “small” project that I took on for a friend, which happened to combine my love of bicycles, mechanical design, and CNC machining work.  I ended up spending a 12 hour day, and then a 4 hour day in the shop – ...

Epic Builds: Articulated Stereo Microscope Arm 2

I’ve wanted a stereo microscope in my home lab for ages.  In the last couple of years, it’s become an increasingly urgent need as I’ve hit the age where my eyesight is beginning to change.  Soldering and inspecting fine-pitch SMD work is becoming difficult without the aid of magnification.  So, I finally picked up a ...

In-Depth CNC Conversion Electronics Overview 2

I converted my milling machine over to CNC back in late 2009.  For most of the time since then, I’ve avoided the project of properly finishing up the electronics that run the machine.  Last winter, I gutted the electronics of the machine, redesigned the system, created a number of circuit boards, and set about revamping. ...

Mold Making & Resin Casting

My friend Matt shared a great link, called the Geurrilla guide to CNC machining, mold making and resin casting.  I’m mostly up to speed on the CNC topics it covers, but I find the mold making and resin casting parts to be pretty exciting.  I have long figured that I am well positioned to try ...

CNC Electronics Enclosure Work Commences… 1

Santa’s workshop was busy today.  I finally got some motivation and time to continue work that I started a year ago, but really, has been a nagging task since day one of getting the CNC up and running.  I have the machine up and running enough to make parts, with all of the controlling electronics ...

HOWTO: Tormach TTS Conversion Kit Installation

Here is a quick how-to video I put together using some really old footage I shot in May of 2010.  It shows how the Tormach Tooling System Conversion Kit is installed onto a Maritool brand ER25 tool holder, converting it for use with my CNC milling machine.  This allows tool heights to be measured and ...

CNC Mill Telescoping Way Covers, Take 2

Quite some time ago (May 2011) I had managed to track down a telescoping way cover for a close relative (Sieg KX3) of my milling machine (Sieg X3), one which happened to come from the factory with CNC capabilities.  The two machines share some dimensions and have at least similar castings, and a lot of ...

More Custom Mountain Bike Parts

I finally got the CNC  mill running well enough to actually run a couple of parts.  My friend had trashed the skid plates that we made for his mountain bike, and he need a couple of new ones.  My machine has been out of commission for a while, since I took it apart last year ...

Magnetic Rotary Encoder Eval 6

I got some samples of the nifty looking AS5040 10-bit magnetic rotary encoder IC from Austria Microsystems.  I want to do some experiments with these chips to possibly replace the mechanically coupled encoder I was planning to use to measure the spindle speed on my CNC mill.  The chips basically have Hall Effect sensors and ...
