HT GPS+Voice: Battery Contacts
Posted by Ed in Amateur Radio, Electronics Workbench, Machine Shop on 16-August-2012
For this version of the contacts (the old version is there) that make the GPS interface look like a standard Wouxun lithium battery, I left a bit more of the slot on the brass screw heads and increased the recess depth to compensate:
The nuts all have fancy nickel plating, with washers & ring lugs silver-soldered in place:
The trial fit looks OK:
I even found the cutest little flat 1/4 inch wrench that fits 4-40 nuts, so I can do a better job of crunching the PCB between the nuts. That excess screw length has got to go, too…
