MARV Progress…
Thanks to a tooth ache, I cannot sleep due to the constant throbbing and have been working through the night for 6 hours straight….that makes it 28 hours of working on the robot since 10am on the 22nd!!
First up, MARV fully re-wired:

This is what the chassis looks like from top; the EPIA mainboard will go on top and fits perfectly with space for the HDD as well…

The completed Motor Driver, fully soldered, and two FT232R USB <> Serial breakout boards, all held on with some really heavy duty velcro (a 50 x 50mm piece can hold up 7kg!!):

LOL...!...
The subject title says it all. There really isn't much to report apart from the fact that all the hard work gone into MARV culminated into a meeting with my thesis supervisor and a simple demonstrati...
This is the CAD/CAM output obtained in gerbv, ...and the completed PCB with one motor driver 'block' soldered on... I hope to begin testing in the morning.....
