Sony NP-BX1 Battery Holder: SMT Pogo Pin Contacts

The original camera battery test fixtures used contact pins conjured from hulking gold-plated connector pins and coil springs:

The Sony HDR-AS30V camera chewed up and spat out a handful of batteries, all tested in the NP-BX1 test fixture:

Nowadays, SMT pogo pins produce a much more compact holder, so I figured I could put all those batteries to good use:

That’s the long-suffering astable multivibrator, still soldered to its¬†CR123A holder.

Obviously, the battery holder should grow ears to anchor the 14 AWG copper posts and would look better in black PETG:

The battery lead wires get soldered to the ends of the pogo pins and are recessed into the slot in the end of the fixture. I used clear epoxy to anchor everything in place.

Fits perfectly and works fine!
