All, thanks for all input! Many useful things to follow up here. Trying to summarize and including a bit more follow-up research. URL’s valid as of June 30, 2015, if you are reading this in the archive; folks suggesting good ideas referenced by name, search nearby here in the archive for contact info. Minecraft gets a special category because a) my son is already addicted and b) I have the suspicion that a *lot* of kids are in his category in that way. It was pointed out quite correctly (Toby Thain) that Minecraft is a *horrible* way to learn physics; my son and I calculated that his character could run and jump while carrying (in its pockets, apparently) a mass equivalent to approximately 7 Iowa-class battleships.
“Hands-on” electronics Raspberry Pi Gertboard interface. Servo motor interface in particular will add real-world interest. (Mark J. Blair) http://www.newark.com/gertboard/gertboard/atmega328-assembled-gertboard/dp/46W9829 LittleBits kits for plug-together components, ex-Radio Shack and available on eBay (Steve Algernon) http://littlebits.cc Modern CMOS should be BE series and hence ESD-protected. CMOS is more tolerant of supply voltage variation. (Dave G4UGM) 74LSxx TTL should generally be capable of replacing standard TTL. TTL is generally faster than CMOS, TTL is more tolerant of connecting two arguing outputs together. 74ALS series is CMOS internal but with TTL interfaces. (Dave G4UGM, Mouse) CMOS 4000 series is very static-sensitive; use a wrist strap and bench pad if you work much with this.
