I've always had a love of LEDs, from repackaging them into common objects to larger scale projects like here. I'm mostly self-taught in electronics, having tinkered and explored them since the time I could first manage a screwdriver. My Grandparents would always save their broken electronics for me, even on occasions where I receive gifts I'd get mechanical or electronic devices bought specifically so I could take them apart! I even used to go dumpster-diving as a kid looking for discarded electronics. Nowadays I go to second-hand shops or discount stores looking for interesting gadgets to take apart and possibly re-purpose.
If your children are always taking things apart - don't get too angry :) That was me. Encourage it! At the very least, redirect it away from your working daily-use devices to "junk" stuff they can play with.
