My parent's house still uses the Heathkit programmable doorbell I put together in 2nd grade (and the tune I made up for it). And I still have my "atomic" clock that reads the NIST radio—same tech as the self-setting wall clocks you can get nowadays, except completely discrete, with 4 or 5 daughter cards, and a speaker so you can actually listen to the beepy radio transmission. I loved Heathkit. I so wish they were still around...
