There is a bunch of cool tech kit stuff on AliExpress for not much money. I ordered one of these [1] (not an endorsement as I haven't built it yet) and I saw a lot of recommendations for other cool things I wanted. Search for Arduino kit, clock kit, etc... The downside is that the included instructions will often be either poor or nonexistent so the hacker in question will need to be confident finding instructions online and filling in the gaps. If you are buying components, the best places are AliExpress and eBay for most things. However for some kinds of chips (expensive or retro ones) you may receive fakes, and the shipping takes a long time. You can pay more and buy electronics from DigiKey or other distributors (be sure to buy a couple more than you need in case they get damaged).
