SPICE battery adapter

[PANAMATIK]

SPICE Battery Adapter is under way.

Many SPICE calculators have the flexible printed circuit board corroded and need a replacement.



The good one and the bad one. I tried to repair the contacts with wires, but it doesn't look nice.

Therefore I made a layout for a replacement SPICE battery adapter and I'm waiting for the manufacturers offer. I hope producing the flexible foil is not too expensive. Also I hope the new battery contacts, which I want to use have 1mm more space for the todays AA batteries. The todays AA batteries are a small amount too long and cause to break the chassis when inserted.





The outline of the battery adapter PCB was difficult to draw and I hope they will not charge extra for this complicated outline.

I want to know how many boards would be needed to have an idea whether my costs can be paid off.
