Well, I’ve been playing around a lot lately with various techniques to mechanically etch PCBs, and I think I’ve finally got a good method. I’ve documented it here on my site for all to enjoy.

Here’s an example of a small board I created using my CNC router. It’s just a small test board for TI’s excellent TLC5925 LED driver IC, but it demonstrates the kind of results I’m getting with my latest fabrication methods.

Why spend money at an ice rink or driving to the lake when you live here in Iowa? 

OK, winter, you can leave now.  I’m officially sick of you.  I was pretty irritated when I got snowed in a couple weeks ago and lost power.  I was more irritated when I bent my plow arms clearing the drifts.  But now, plowing in vain with a plow that won’t level against drifts that won’t stop in wind that bites my face, I’m officially ready for you to stop.  Please go.  Please.

Thank you,

Brad

Well, I made some more tweaks to my CNC Router setup over the weekend. The most exciting addition is the complete integration of my new MPG2 Jog Pendant! Some of the EMC2 HAL integration work took a little thinking, so I made a new MPG2 Jog Pendant page to get other similarly inclined EMC2 users up and running with all 4 axes. Now, if I could only get my butt in gear and finish the shop, I’d be set!
