If you don’t have big places to buy electronics, a trip to one of the Fry Electronics stores would be a nice diversion. If they are shopping for bits and pieces of electronics, Weird Stuff or HSC would also be a possibility. San Francisco public library main branch has a massive computer/technology section. (if you get a library card you can check out e-books) If you re interested in engineering and a little hiking the SF streets the cable car museum is cool (corner of Mason and Washington). If you are into games and mechanical amusement Muse Mechanique at pier 45 next to (Fisherman's Wharf) is something to see. Exploratorium is also in the area there.
