Also, if you don't mind traveling a bit further, there's the Moffett Field Museum (http://www.moffettfieldmuseum.org/), Intel Museum (http://www.intel.com/content/www/us/en/history/museum-visiti...), and a bit further south is the San Jose tech museum (http://www.thetech.org/).

If you have a car, it might also be worth going to Stanford's campus -- just take a walk anywhere.
