Today they arrived!
They look good even if I say so myself! Nothing like black solder mask, silver pads, and white silkscreen!
I'm not going to lie, it was a good feeling assembling and testing, and then finding out they fit, and work first time! Not bad being done by eye!
Dave has ten of these prototypes for assembly and distribution winging their way over to him. With his approval I'll move to bulk production. This is only the balance PCB
, the power is still a WIP.
A couple of notes so far from my assemble and testing...
1. Recycling the old microswitches from old boards is a no go. They don't fit! The new ones ordered from RS fit perfect (as they are suppose to
) they are tight, and for the OTT'ers you can use a drop of epoxy glue. They wont move in a bomb blast.
2. The pins are snug as well. All the solder must be removed from the old pins to assemble them to the new boards. If any is left you cant push the pins in and risk causing some damage. That said this method is preferred as soldering is easier if the pins dont move around!
3. We need a supplier for pins! I'm still running quotes in excess of Ã‚Â£3-5k!
