Here are a few more pics of my build. This is my enclosure for the TinyG and speed controller. I had a spare fan I used to move lots of air through the box. It’s a bit of a tight fit but I think everything will fit nicely once it’s all connected. I made a hole for access to the USB port and added a power switch which I can use for emergency shut down if needed.
Thanks! It’s a cheap RadioShack enclosure I picked up for about $7 on sale.
The colored LEDs are a nice touch, too. 
I’ll have to check my local Radio Shack to see if they have one of these enclosures. I have a nice big fan from an old dead PC power supply and I have yet to wire up the electronics for my OX, which includes a TinyG and spindle controller, same as you. It would be nice if I could find one big enough to include a Raspberry Pi 2.
@SirGeekALot Thanks! I like the LED fan as an indicator that I have power going to the TinyG. It too was harvested from an old dead ATX power supply. I have contemplated the RaspberryPi idea and actually have a B+ version sitting at home. I just don’t know if the graphics card can handle the 3d interface on chilipeppr or Jscut? Maybe the Pi2 can handle this better but my B+ when used as an XBMC media center did not perform well.
I have a couple of Raspi Bs as well as one Raspi2. I will probably try to use a regular RaspiB first, and if that doesn’t work then try the Pi2. But, I think the old B should work just fine, as long as latency doesn’t become an issue when driving the TinyG. I’d love to hear if anybody has already tried this with success (or not).
Alternatively, I also have an Intel Galileo v1 that might work as a headless host. But being completely headless coupled with not being able to get it to work on the first attempt (and thus having no way to “see” what is happening to fix it) has relegated it to my “maybe someday” pile.
@SirGeekALot I’m interested how that works out for you. I would prefer to not leave my laptop sitting next to all that saw dust for hours. If a B+ will work I might give it a shot.
