the otona no kagaku diy magazine/kit have done it again. this time they've created a diy TLR(http://otonanokagaku.net/magazine/vol25/index.html). i got mine two days ago, assembled it a day ago and shot a test roll(two shots posted below). it's very cool. possibly the favourite of these kits so far.

i guess i just still see them on ebay ocassionally. there is a stereo camera kit on ebay right now for $32.

gary--where did you end up getting one from? i made three separate orders from three different places. it took them all a week to cancel my orders and say it was "out of print".

i think the stereo pinhole kit is still in print. at least it was still in print when issue 25 was published. issue three had some other kind of camera, and that one is out of print now.

william

i have the first camera. it's a pinhole, but it also comes with a plastic lens to make it a "real" camera.

ah, that is indeed it! i have a kit that was put out for the taiwan and hong kong market that is licensed from gakken, i believe it's supposed to be that camera, but it doesn't look quite the same. i thought i had posted about it here a long time ago, but looking now i can't find the post.

I couldn't wait.

Took about two hours to put together including getting the shutter to work which required a bit of trimming of the plastic. A bit of trial and error in parts as well as I couldn't read the instructions but overall, not too difficult.

formica · « **Reply #6 on:** December 15, 2009, 07:06:48 PM »

two of the springs are mislabelled in the instructions, just in case anyone is having trouble getting the springs to fit in the proper locations and can't figure it out. i hope everyone posts some test shots once they've shot 'em!

i didn't find the shutter to be particularly complicated...just a bit fumbly with my big fingers. there are only 3 parts if i remember correctly.

peeling the dbl sided tape for the mirror sucked! and i'm all out of my poster tape...so that was 5 minutes worth of messing about.

i like the gakken mags. skorj! it has a fujipet in it, as well as a history of film and some fuji film boxes.

Yup! Yours then is really second-hand, as I read it already. Nice magazine details there too. Much enjoyable.

They have apologized for this I see on their web page, and added the correct labels too:

本誌86ページ「ふろくの組み立て方と使い方」の部品名称に間違いがございました。バネの名称ですが、正しくは下図の通りとなります。ここに訂正するとともに、お詫び申し上げます。

The best part to me would be using the seal templates and choosing a suitable covering for it...

http://otonanokagaku.net/magazine/vol25/pdf/vol25seal.pdf

Glad to see two have arrived safely, and I notice it has a Sport Finder and adjustable vignetting as well. Neato. Looking forward to the results. Skj.

The problem I had was the pillar that the intermediate lever is on (that's the one where you have to leave the screw a bit loose) was slightly fat at the top and, as the lever lifted to get over the little step on the shutter, it would jam. I just pared off some plastic from around the top of the pillar and that fixed it.

Any chance you can translate the bit which mentions moving the aperture ring from behind to infront of the lens. The bit before it seems to be suggesting different film speeds for indoor/outdoor use but is it also suggesting the aperture should be removed?

mikeg · « **Reply #12 on:** December 16, 2009, 09:38:13 AM »

Mine arrived yesterday. Looks really good, haven't had time to build the camera yet. As others have said, the magazine seems to have some interesting stuff in it, just wish I could read Japanese.

I notice that the shutter does not have a B setting. Does anyone building this think it may be possible to keep the shutter open?

Many thanks to Skorj for getting this for us and for sending it so quickly.

Cheers

Mike

I will try!

Normal photographs in focus can be taken by using the aperture plate in the normal position. Greater depth-of-field can be obtained by removing the aperture plate, and a strong vignette can be obtained by installing the plate in front of the lens.

Left to right: Normal position, aperture plate removed, aperture plate in front of lens.

The section on film speed is an aperture vs. film speed guide as you would normally expect; with the aperture plate in, you can shoot ISO100 outdoors in bright sun, and while indoors you can shoot ISO400 with the aperture plate removed.

Assume this makes sense when you have the camera in front of you. がんばって！　Skj。

I was thinking the same thing. I modded a Vivitar UW&S to keep the shutter open and it should be possible to do something with this. I'll think on it.

moominsean · « **Reply #15 on:** December 16, 2009, 05:33:59 PM »

not exactly easy to just pop the aperture plate out, but nice that they thought about it.

they seem to be very open to modding and experimenting. i should send them a link about my stereo/pano mod with the chinese lens.

Pete_R · « **Reply #16 on:** December 19, 2009, 04:47:04 PM »

Some results.

I've posted others in this weekend's thread here.

All the pictures were taken close up. I wound the lenses out as far as they would go without them falling out which got me to within about 12 inches of the subjects. I also decided to remove the aperture disk and also the funnel shaped piece that holds the taking lens in place. The lens stays in OK without it and I thought this would give the largest aperture possible and hence minimum dof. I'm pretty happy with the results.

Only problems I had were forgetting to wind on (no double exposure interlock on this one) so I got a few double exposures and also the frame spacing is variable. I'd recommend winding on a bit extra each time if you want to be sure of not getting overlapping frames. I also forgot to allow for the parallax error which, of course, was significant as I was close to the subject.

Piet, I particularly like your last two.

Did you have the aperture plate in front or behind the lens?

Peter, the aperture plate was still in it, but after i've seen your pictures i removed it and give it another try..

pdewolff · « **Reply #23 on:** December 24, 2009, 08:08:44 AM »

Oh, the plate was behind the lens..

hookstrapped · « **Reply #24 on:** December 24, 2009, 09:48:36 PM »

Mostly a lot of flare off the low sun and snow.

Next, some close-up with the aperture plate removed... :chinscratch:

They were on XP2 processed in Aculux 15 mins. This is my usual combination and I usually rate it at ISO 200. A couple of shots taken outdoors in bright sun were over exposed but most were OK.

Skorj · « **Reply #27 on:** December 27, 2009, 01:40:45 AM »

Hey, these are pretty neato! Pity I cannot find any more in the shops... The next edition is an electric guitar. Incidentally, I think a previous edition - a mini Theremin - was so popular, they reissued it. So, the same might happen with the TLR if similar demand exists. Love those covers too! Skj.

OK. As long as you're sure. Thanks again for getting them anyway.

100%! Happy to see them used! Plus, I cannot keep the benefits of living in Japan all to myself... The last two sets must be popular, as out for grocery shopping I saw this line up at a local hon-ya, I went back today and the 25 (TLR), and 26 (Guitar) were gone. I noted too the non-current editions were tagged at \3250, and not \2500 as per the present issue. Such is life! Skj.

Left-to-right from Volume Nine; phonograph, telescope, kaleidoscope, hand cranked projector, doll, Theremin, fan, electric organ, electric engine, electric something, valve radio, synthesizer, TLR, electric guitar...

i have the theremin. it's a bit on the squeaky side, but fun nonetheless. i was always under the impression that the price depended on what the kit contained. alot of the kits you can find on ebay. you may also be able to find them at japanese bookstores(like kinkouyia(i can't remember how to spell it)). they all have isbn numbers so in theory you should be able to have a shop special order them for you.

Easy!

Get him to drop me a note for further instructions if needed. Though now in reprint, the main bookstores are perhaps unlikely to have large quantities, where as some of the specialists like Village Vanguard & Camera Cabaret are more likely (as per above). I will check their stock level tomorrow, and amend this if they're all gone or something traumatic like that. Skj.

okay i know this is an EXTREMELY OLD thread but i thought i would revive this instead of making a new one. I put together my gakkenflex ages ago and never got around to using it. i dug it out my camera tomb and completely forgot how to use it.

how many winds do i do to advance the film? is it one full rotation? also, its pretty hard to focus (for me at least) does anybody know a good way to zone focus with this? any info/tips would be much appreciated thanks.

A half rotation equals one frame advance, theoretically, but it doesn't always quite work out that way so I do 3/4 a rotation. Of course, I end up wasting even more film than normal but, hey...

I found that the focus worked pretty well, until I took out the aperture ring. But before I did that it seemed to focus well and now it still gives the appearance of focusing well.
