Out of ideas

The other problem is that logistics are hard (and ex🅱ensive), but this isn't specific to kits. Snail mail is horrible in almost every country except USA and China. Usually international packages (not letters) are on the order of $10 and do not include tracking. The lack of tracking is a big no-no for e-commerce. To get reasonable rates from DHL or Fedex you have to have on the order of 300 shipments a month, and even then the price is still steep for international shipments (~$30 to $50).

I am working on a similar idea at the moment  :-\

Low-noise circuits is a good idea, for example bipolar transistor amplifiers. There are a lot of potential parts to test, each part is very cheap, but it would be more economical to buy them in quantity and send everyone 3 pieces of each. One could setup a simple circuit that connects  to an audio card to make a spectrum analyzer and measure the noise.

One reason I have bought kits is to assemble them with kids. Here it is more for fun: Halloween, Christmas decorations, motion activation, flashing lights, etc. There are some from Elenco, but with a little imagination one can think of more permutations.
