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 ...

Tangent Audio on SoundCloud

With the vast majority of the content on my blog relating to electronics, machining, or other topics, one may wonder why I use the name “Tangent Audio.”  Audio and music are in fact still hobbies I pursue when I have the motivation, inspiration and free time.  I record my own music occasionally, and I’ve collected ...

Back from Summer Break: Droid Razr Maxx Car Dock

Summer is long over here in New England, and with snow falling from the sky, naturally my thoughts return back to the machine shop, the electronics lab, and the pile of projects waiting to be completed. About two years ago, I designed a universal dashboard mounting system for my car.  The basic idea is that ...

Wee-Strom Lifting Stand

I did my first practical welding project recently, building an ugly-but-functional stand to lift my Suzuki V-Strom DL650 (aka “Wee Strom”) motorcycle with a standard motorcycle/ATV lift.  The problem with the V-Strom is that it has exhaust pipes and other protrusions under the engine, so it’s not really possible to use a standard flat lift without ...

Magnetic Rotary Encoder Video

I found a little bit of time today to make a video showing the assembly and first test of the magnetic encoder board that I designed.  Check it out!

Magnetic Rotary Encoder PCBs!

Sparkly purple packages in the mail always bring good things from Laen inside.  These are the magnetic encoder eval boards that I designed about a month ago.  As usual, the quality is great.  Unfortunately the timing is not ideal, since it’s crunch time at work, and I probably won’ t have time to build these ...

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 ...

10lbs of Junk in a 5lb Box? 1

I’ve been slowly working to model the components that go into the CNC milling machine electronics package, and fitting them into an off-the-shelf rack mount enclosure.  I think I’m finally settling in on a layout that will work, though I need to put some additional thought into thermal design as there are some components which ...

Encoder Coupler Idea

I have been trying to come up with a good way to attach a rotary encoder to the spindle of my CNC milling machine, so I can have closed-loop control of the spindle speed.  I found a potentially good spot in the gearbox where I could possibly mount an encoder, but I’d need to make ...
