Tindie is the marketplace for makers to fund & sell their hardware creations.
I have started selling some basic kits for hobby use and also NOS parts I have too much of.
These are priced cheaply and the mark-up I make barely buys me a beer, so it is not at all a side-business, but more of a contribution to the hobby and community.

Crowbar Protection for Ham Transceivers Kit

OUCH ! – Get a crowbar for linear PSU or go SMPS. Click HERE for Crowbar kits. […]
