Ask Slashdot: Gifts For a 90-Year-Old, Tech-Savvy Dad? 211
First time accepted submitter Bearhouse writes "My Dad amazes me with (a) his longevity & energy, and (b) his continued ability to mess around with electronics stuff. Since he already has things ranging from valve amps made from war-surplus, via an original IBM PC kit to an Android tablet, I was going to buy him a Raspberry Pi for Christmas. Turns out he's already got one. I saw nothing that really got me excited here, so your ideas would be appreciated."
