Early power-electronics experiments
A collection of early capacitor, voltage-multiplier, and repurposed camera-flash projects.

A capacitor bank I assembled from spare capacitors, possibly during college. A capacitor bank stores electrical energy in a group of components. The charging electronics on top used comparator circuits and LEDs to indicate different voltage levels.
A voltage-multiplier circuit with a large capacitor, built in an electronics lab at Lehigh University during 2011–2015. I frequently visited the lab to work on projects. I no longer recall the exact application of this particular circuit.
Camera-flash bench assemblies

Camera-flash charging circuits mounted on small pieces of wood for early electronics experiments. The wooden bases made the separate assemblies easier to handle on the bench. I adapted them for larger batteries so they could run longer. I no longer use these assemblies; later projects use dedicated voltage modules.
Earlier voltage-multiplier project

An early voltage-multiplier project, a circuit that raises voltage in stages. It may have come from a kit, but I no longer recall the exact kit or date.
Earlier aluminum-washer experiment kit

A kit I bought and assembled for an aluminum-washer experiment, probably while I was in high school. I only used it a few times, but assembling it was a useful learning experience.
