Barbouri's Electronics Projects

Minor upgrades, maintenance, and cleanup of a Hewlett Packard HP 3457A digital multimeter.

With eleven power supplies already, I really didn’t need another one for the bench.

The Victor 204R is different, but very much the same calculator as the Victor 204 Medalist originally produced by Victor Comptometer Corporation.

After repairing the Nakamichi 610 FM Tuner / Preamp back in late 2023, I have been on the lookout for a FM tuner for the workshop audio system.

This time I am working on another radiation scaler/counter which is quite a bit different than the last one.

I finally came across a hard to find HP 5306A Multimeter/Counter paired with the HP 5300B Display module.

After installing a dual-input power transfer panel for power outages at the house, I was in need of a large battery for powering the second UPS input on the panel.

Something a bit different than my usual test equipment and calculator projects is this Picker Nuclear Compact Scaler built by Intertech.Quite a few people may be wondering.
