Hi,
Taken another step closer to completion, unfortunately started Uni again so things are going to slow mo for a while but I hope to allocate an hour or 2 a week just for my projects including the obs.
This time I have an embedded computer that I collared for $10.00 (actually 2 computers) along with a plotter that I have raided for bits. The bits for this build are:
- 240Vac to 24Vdc 8A power supply
- Embedded 2Ghz embedded system PC.
- Case to mount everything
- some very high quality wire.
I also scored a load of other devices including motors installed with encoders and stainless steel linear sliders for building a 3D Printer in the future. This is a really good score for $10.00 mostly because people didn't want the plotter due to it's size. Link to plotter -

Still have to configure the PC but limited buy the manufacturer disabling the USB Legacy in BIOS, so I need a PS2 keyboard and mouse to reconfigure before going ahead.
The images show the case almost complete, the CNC motor driver are the 3 heatsinks on the case and 3 x 21kg Stepper motors. Best buy for most of this stuff is from

although I got a 5 axis stepper controller on eBay.
