One thing leads to another! In an attempt to build a cnc foam cutter it
became apparent that I would need some electronics experience. so I set
out to learn on the fly so to speak. I built a hobbycnc driver board. all of
the test ran well until I hooked it up backwards and burned it up. Let
out the magic smoke you know! After that I decided to buy a board to
speed the process a little.
I did need a power supply and assorted resisters to make all this magic
happen. Here is a picture of the driver section of my foam cutter.

Now I am building a pic chip driven controller board from
pminmo.com They have an awesome array of diy
electronics projects for cnc there are plans schematics
and lots of toner transfer pdf files for pc board building.

The last three pictures are of the pic based

The tool with the drill chuck is micro sensitve drill adapter. you chuck it
up in a drill press and you feed it with your fingers. It works great!

The process of toner transfer pc board making is 1. Print out the circuit
in a mirror image on gloss paper. 2. Cut board blank board to size. 3.
Iron on the toner. 4. Soak the board in warm water until you can peel
off the paper. 5. Etch 6. Use thinner to remove the toner. 7. Drill the
appropriate size holes. Now you have a finished pc board. Here is some
more detailed info on pc board building with some recipies for
homemade etchant that works like a charm.

This board was designed by a friend
of mine. Chris he is one of my
partners in crime with this hobby

Chris is building a remote control for his auto-crane on his work truck. It
will lift 5,000 lbs. His remote will control all of the functions of the crane
like winch up/down swing left/right boom up/down telescope in/out. It
uses an 8 button remote. I will add more pics as they are available and I
will try to post a page with detailed info on the process of this build.

This is our first try at a double sided board. This is a prototype to see if
it will work as designed. The first board worked but we had some trace
problems and component placement was tight in a couple of places.
These areas were fixed and another board was made. The secand board
was much improved over the first one.
