Default Re: Improvising with Household Items.

A PW TRF design in the '60s used toothpaste caps as the knobs for tuning and volume. It's an idea that has stuck with me but I've never tried.

In a similar vein, I needed "cheeks" for an inductor I was winding and used the caps off baby food squeezy sachets and holt-melt glued them on the ends of a ferrite rod before winding on the wire. I'd actually been saving them as wheels for a Mister Maker type activity but this use is better!
