A one minute teardown answering the question “What is Inside an Electrolytic Capacitor” requested by Ray & Mike from the GRC Pinball YouTube Channel in their latest video “Ray’s Pinball Tech Tips S3E5” Session 3 Episode 5.

The darker aluminum foil is the Anode side (+ side) which has a thick aluminum oxide “~rust” Al2O2 layer that is the acting dielectric material in this capacitor.

My first mailbag video which includes the LONGEST ever pocket digital multimeter review in history. HA

I found the Victor 921 pocket multimeter to be the best pocket DMM I have ever used. It showed quite close to exactly correct readings for all measurements and had capabilities way outside the normal for a $25 pocket multimeter not only in build quality but also in features and functionality.

In this mailbag I also showed a jimmy knife tool by iFixit and some SOIC-8 / TSSOP-8 combo DIP adapter PCBs by Adafruit. Here are the links to all the products in today’s Mail bag.

I won a nice 1970’s Grandfathers clock in an estate auction a few weeks back (see video here) and it needs repairs and service. One simple repair was to either replace or repair the door lock so it wouldn’t keep flopping open. I figured this would be a good excuse to try my hobby welding skills on some real small work. In this video I give a bit of background on how the little door latch works and take a couple wacks at welding it up. Below the video are some useful links.
