I visited a great museum today, the Anglesey Transport Museum or Tacla Taid:

This is much more than a transport museum, though. Although the majority of exhibits are automotive-related, there are numerous vintage radios, a Sobell 405-line TV, a Fidelity Playmaster, a host of vintage domestic electrical appliances, meters, tools, stationary engines, generators, field telephones, searchlights... they even have several NOS 10 volt lead acid accumulators. My own quirky interests in model steam engines, paraffin blowlamps, Tilley lamps, Primus stoves etc were all well catered for.
You may also get time to look at the old cars, tractors, military vehicles and even the Hawker Hunter. Altogether an eclectic display with plenty of excellent explanatory material in a fine period setting. And at just £5.50 entry (senior) with a cafe and kids' play area, there's really nothing to dislike. It's quite easy to find, too, being not a million miles from Llanfairpwllgwyngyllgogerychwrndobwllllantisiliogo gogoch.
