Mesa 5124/25 with a +/-10V daughter board.

I'll find out when I wind them up next week. The cables suggest they have both a tach feedback and quadrature encoder, all balanced signals.

Thanks! I'm kinda cheap, gets me into trouble sometimes! The labor is free and I'm getting the students to do some of the work with me.

Ah, free slave labor. One of the many benefits of being a mentor

The router is one of the machines in a Makerspace we setup to benefit the FRC team. So in theory the team will get something out of the work - some day!

I think Sodium Carbonate is what you want, and baking soda is sodium bicarbonate, or maybe I have that backwards. A 6 Amp Schumacher manual (not automatic) charger works well as the power supply, as does an ATX computer power supply. Use any scrap steel for the electrodes, and I recommend more than one electrode.

Baking Soda (Sodium Bicarbonate) is NaHCO3, which in water is Na+ and HCO3- ions.

Sodium Carbonate is Na2CO3, which in water is 2Na+ and CO3-- ions.

Sodium Carnonate is a very strong caustic base (pH 11); where baking soda has a pH around 8. The purpose of either is just to be an electrolyte. The compounds don't take part in actual reaction.

Baking soda might take slightly longer, but it's solution is far safer to handle and dispose with afterwards. As a bonus, most people that bake will already have some at home.

The fact that it's hand held scares me deeply....

EDIT: WHAT THE HELL, it's actually safe for human flesh?!?!?!?!? http://www.roadandtrack.com/car-cult...remover-laser/

Awesome! That's what we are running. 1 ms cycle with LinuxCNC and it's working great. Ping me if you need any help. I even rebuilt the verilog to support our specific set of daughter boards.

Looks like a fun project!

Thanks! I might hit you up for some help. All in Verilog, nothing in VHDL?

I can't remember. Might have been VDHL. If you dig through the documentation, you can eventually find instructions on how to build a new image, or give me a holler. It took me a solid day to figure it all out. (If you need a prompt response, I'm waaay faster on gchat).
