The PCB above
includes the amps and DC-DC supply for the Mixer Expansion.
Done in KiCAD it's going to be a first as a CNC with isolation routing was
used
in place of the usual photo-sensitive PCB I generally use!
Anyway, this box is a special design to hold batteries and allow a pair of work clamps to be attached so it can be easily mounted to edges of things. So the board is being CNC milled as I type this, wish me luck!

Well it didn't turn out half bad. Used the 15º milling bit at 50mm/minute
so took a while. I had an issue with drill bit sizes. I have none between .5mm and 1mm so I ended up using the dremel drill press to expand out the tiny holes for larger leads (headers, zeners etc) which can be seen in the photo right. CNC drilling is amazingly accurate..those are 1.6mm via's! The edges need to be trimmed still even though I could have done the edge cut with the little cnc2417, it's just as easy to do it with our big bandsaw! |
