Well, I just finished putting my 500 EL\/M together after almost completely taking it apart.<\/p>\n
So as usual I went to use it one day and the $150 batteries were dead. It stopped mid-stroke, and I was in the boonies, so I cocked the camera manually to remove the lens. BAD IDEA<\/span>.<\/p>\n As far as I can tell, that forced something past something, and the result was that the front gear train (which cocks the shutter in the lens) ended up being out of phase with the rest of the camera. I took the whole thing apart, referring to the service manuals, which although detailed are a pain to read as they frequently refer to parts by the part number which may or may not be shown in the adjacent figure.<\/p>\n In any case, after taking the whole thing apart and re-synching it I realized I had also stripped a threaded shaft which threads to a gear connecting the winding motor with the body. Saying “what the hell” and deciding I could easily convert it to a manual in the worst case I epoxied the shaft to the gear, which so far seems to hold up.<\/p>\n But anyway. I should have taken pictures to post, but I didn’t have time to take any. The point of this is that at the time I wrote “My First Post<\/a>” I couldn’t find the DIN connector used for the electric Hasselblads anywhere. It is a 5-pin DIN, with the pins at 270 degrees (see this link<\/a>). It turns out some refer to this connector as “240” degrees and I just found out they also refer to it as “60” degrees (denoting the angle between adjacent pins for a total of 240). In short, I found it on Mouser<\/a> for $2.66.<\/p>\n Cool thing is that I think you may be able to power the camera from there—via external battery pack or AC adapter. Also, I’m going to try to find out how much voltage that thing can take. Seeing as how everything is pulsed in operation, it shouldn’t be a problem to double or even triple the voltage as all there is is a solenoid (to release the camera) and a motor which is controlled via limit switch in on-off fashion.<\/p>\n I’m definitely going to get rid of these damn batteries.<\/p>\n","protected":false},"excerpt":{"rendered":" Well, I just finished putting my 500 EL\/M together after almost completely taking it apart.
