I thought to post this.
It is the internal circuitry of a discontinued Burr Brown DC/DC convertor. I took the top off of one to expose the internal circuitry, die chips, SMD diodes, toroid.

This is cool to me. How many of these you have around?
On a note of humour. If a Mig-25 or other Soviet aircraft crash. I be interested in some vaccum tubes to sell to the Rock and Rollers.

Pulled this out of a baby swing/rocker that played sounds for little ones while they sleep. Did not expect to find this in there.

Air variables have that proper old radio gear look, even when the rest of the chassis is long gone. The vanes catch the light ridiculously well in photos too.

Many small electronics have nice looking boards.
