Hi guys,
I've spent the last 2 weeks in Japan (Tokyo area) visiting family and exploring. I've posted a few photos that I thought you guys might find interesting here:
The first few pics (and MPEG video) are of Tokyo's famous "Electric Town" Akihabara. In the confined space beneath the train line there is a thriving market... But, this particular market doesn't sell fruit, veg, or even raw fish, it's actually full of little shops selling every electronic gadget and component you could think of! (Not many places where you can pick up a 1000A thyristor and RF Vaccum tubes whilst in town doing your weekly shopping.)
The "Mylord box" was a piece of electronic art in the form of a 10x10x10 ft touch-sensitive cube covered in lights. It was located at the end of a busy street near Shinjuku main station. The plastic case had hand symbols printed on it to encourage passers-by to touch the surface. Doing so started a swirling pattern of colours, a growing light spreading from where it was touched, or snowfall that gradually built up at the bottom! Neat! It would even leave an after-image of your whole body if you stood against the surface for a few seconds, and was bright enough to light up the street.
The last few pictures are in reply to the one posted on here some time ago showing cables coiled up overhead. There's lots of overhead wire in Japan, because it's an earthquake zone so expensive to dig up and replace damaged cables. The top of the poles carry 6600V lines (the local distribution voltage) and lower down is the 100V to nearby buildings. The transformer is balanced on the pole somewhere near the top, with a sign near the bottom reminding people not to stand underneath: Remember the earthquake problem! Their tendancy to hang all of these wires overhead also causes a lot of surges to residential properties due to the frequency of lightening in the area

Wow. I really like those pictures you took. Those are some expensive audio tubes Did you get any electronics parts while you were in Akihabara? *wants to go to japan*

We used to have electronics shops like that in Britain - piled up to the ceiling with WW2 electronics - WS19, WS52, Parmeko xformers, magnetrons with giant magnets, all at giveaway prices. Now we only have wishy-washy Maplin, though I guess ebay has more than made up for the loss.

Great stuff Richie! I've always wanted to see the Akihabara market, it looks like geek heaven. I think they'd be envious of my tube collection, though.
Harry: I remember the last of the surplus electronics stores, though they all went out of business years ago. There was a little shop in Glasgow's Saltmarket street, like a sweet shop but stacked to the roof with goodies like miniature light bulbs, buzzers, crocodile clip leads in every colour of the rainbow, and CB radios.
Maplin are OK, I needed parts to build my guitar fuzz box, and was able to get most of them over the counter.
Ebay is OK, but it's not half as fun as rummaging through boxes of stuff in a real flea market.

Those are some cool pictures! What an interesting side of Japan to see. Most pictures I see of that country are the same; people eating sushi, kids dressed up crazy. I like seeing the more everyday aspect.

That's exactly what it was like Steve. Each stall was literally packed with stuff in little boxes, zip bags and trays from the ceiling down to the floor. Some also had cardboard boxes full of miscellaneous "junk" around the floor too. I wish I'd had a few hours to rumage!

Yeah, the exchange rate now is 150 Yen to the pound (or about 92 Yen to the US$) so some of those tubes are worth over a grand!
I bought a few transistors that are hard to get here for an analogue synthesiser project, that's all. (Hopefully these genuine parts made in the land of the rising sun will have special Ninja powers and make it sound as good as a Roland, Yamaha or Korg!)
Japan is a great place to visit if you can think of a reason to go. Very clean, very efficient, and very little street crime. Food not great though.
Watching the engines of a 747 wobble as we landed at Narita in a Cyclone wasn't much fun either!!! (>.<)

There is still one of those type of shops here in Derby called RF Potts - it's a family owned setup and the front window looks like that shop in Richie's video. I used to buy components from there all the time when I was a kid, it's probably what got me into building stuff, because I knew I could just go and give them a big list of components and they would go and find everything, even germanium transistors and it wasn't that long ago! I feel guilty using the likes of Farnell nowadays, supporting local business and all that.

Bring back HL Smiths, Proops, (the original) Henry's Radio etc.
I worked in Hong Kong about 18 months ago - there's an area in Sham Shui Po (Kowloon side) called Apliu Street and that is FULL of electronic component stalls. I have an HK Chinese colleague who is into tube audio (like me) and who took me around - most of the stall holders only speak Chinese dialects and you need a native speaker to spot the fakes and to argue for the "local" price (not the tourist one). The Golden Centre is full of 1000s of gadget stalls similar to the ones in your photos.
Interesting that you showed a lot of tubes - not at enormously attractive prices either. FWIW, HK was the same - my colleague says that even he doesn't buy tubes in HK any more - he buys either from the mainland or from eBay - its cheaper.
What were very cheap were amazing audio/video cables, big capacitors, amazing gadgets etc. You have to be selective...
