Hobbyist Tech Magazines in Japan

Radio Life

IMG_2140Radio Life is somewhat unique, I suspect Radio life was originally purely a ham hobbyist magazine. Over the years, and I assume with a decline in ham radio, radio life seems to have morphed into something quite different. While the magazine still has a strong focus on ham gear it also features articles such as the one shown below reviewing meat dumplings (nikuman) sold at convenience stores. Being the geek publication that it is, the magazine uses thermal probes to measure the internal temperature of the meat, as well as weighing the meat content. This is fairly typical of Radio life, and there’s usually a feature on some household or convenience food, examining the item in excruciating depth.

Radio Life is also tends towards the greyer side of hacking having featured articles on hacking pay TV, the best chinese anime steaming stes, and reviews of popular porn sites. It’s a bizarre, and unique publication in Japan.

Nikkei Linux

samba

Samba, confusing in any language

For the most part Nikkei Linux is a pretty standard Linux magazine. However it does have a magazine twist, featuring Linux based education Manga like the strips on Samba shown to the right. The girl here is saying “let try our best or configure Samba”… I know that feeling…

Sudo denied!

 

Interface

IMG_2137Interface caters mostly for the digital electronics crowd. Compared with many publications it’s pretty hardcore. Featuring embedded systems programming, and digital electronics. The Raspberry Pi has taken Japan by storm (exclusive Raspberry Pi publications are also available), and this months Interface featured the Pi in depth. Previous issues have featured other microcontrollers, including those only generally found in Japan (like the SH3). It’s an interesting magazine, but with a heavy digital focus I find it slightly less exciting than some of the others available.

Transistor

IMG_2138Transistor is just awesome. It’s probably my favorite Japanese tech magazine, and makes me wish I was able to read Japanese to the degree that I’d be able to puzzle my way through the articles. In the past Transistor has featured 50 page articles on NiMH battery technology meticulously benchmarking popular newcomers like the Eneloop and discussing recharge circuitry, discharge rates, and capacity. They’ll also delve into subjects such as capacitor chemistry, and techniques for eliminating noise in analogue systems. This months Transistor was a little less interesting to me as it focused on the digital world, specifically FPGAs. The magazine however covered the topic in its characteristic depth, reviewing all the generally available development kits and presenting tutorials to get the user up and running.

 

Software Design

softdesSoftware Design is the magazine of the software hacker. The magazine has a heavy focus on Linux and DevOps style engineering. The issue shown here obviously re-ignites the editor wars, but it typically isn’t quite so contentious. For the most part Software Design covers recent trends and techniques, presenting detailed tutorials on getting up and running with containers, deployment systems, or new Linux distros. Somewhat ironically I’ve not really found that it covered programming in depth, focusing mostly on what would more commonly be called DevOps.

Robocon Magazine

IMG_2135This one was new to me, but I guess a list of Japanese tech magazines wouldn’t be complete without some mention of Robots. These small robots seems to be gaining popularity in Japan with specialist stores popping up in Akihabara. The robot kits cost from 500 to 1000 USD and appear to be pretty awesome. The magazine seems to cover recent events and new develops in the community.

That’s it for this roundup, I’ll try and dig up more of my favorites sometime. One publication I’ve missed is “Hacker Japan”, this covered MIT styling hacking (describing early astronauts as the prototypical hacker) as well as the darker side (like pay TV hacking) and interesting publication, but it appears to be getting rarely recently.

NEC Teledata Terminal Shop Register (TD7)

I picked up this shop register for 500Yen (~5USD) in Akihabara the other day. It seems liked a steal for a barcode reader, 24V power supply, thermal printer and Windows CE computer. I figured it would be worth the money for a teardown and to salvage the parts. I’d guess this device is from that late 90s or early 2000s. Certainly WindowsCE was all the rage then. The register was manufactured by NEC and for the most part uses Japanese parts. However I was surprised to see a Marvell microcontroller, Intel flash, and Samsung memory. Rather than the more typical SH3, Elpidia RAM, and Toshiba flash produced in Japan.

An interesting find anyway and some useful parts for the junk bin.

A 1960s Japanese Telephone

I picked up what I assume is a 1960s era phone in Akihabara a couple of weeks ago. It uses parts from a varietty of Japanese manufacturers including what appears to be Riken corp. the design comes from a time when manufacturing in Japan must have just been picking up speed after the second world war.

It’s a model 600A phone, and there’s a great Japanese site detailing this model and its variations. By best guess is that these phones would have been installed by NTT directly.

I also have a British phone from the same era. It was interesting to compare the construction, shown below:

The Repeater – CP-33 Repeat Card Player

IMG_0042

I found this thing in the Akihabara Hardoff store. I had no idea what is was but figured for 540Yen (~5USD) it was worth a look. From the limited information I’ve been able to find it appears to be part of a card based learning system. The user swipes creditcard like cards through the device, which reads the magstrip and plays back an audio recording. As far as I can tell the device is used for flashcards. Perhaps a Japanese word might be written on the card and the user would have to guess the English. They can then place the card in the device to hear the audio.

The player pulls the card through the read system at a constant speed. It then reads the card and samples the audio, as the name suggests it can repeatedly replay the audio track.

I though this was an interesting analogue storage/digital playback device designed right at the cusp of our transition from analogue to digital media. I’d guess this particular player was built in the early 90s, though I couldn’t see a data code. It’s also interesting the it uses a TI part (TMS3477NL) this appears to have been specifically design for audio recording and playback.
