- Any help with technical documentation would be greatly appreciated.
This video is posted in the faint hope that some Polavision enthusiast somewhere will sympathize and be willing to help. 🤞 - ยานยนต์และพาหนะ
Amazing machine… Polaroid was an innovation machine ,, well till this bombed…
some engineering went into that thing
Oh for sure…Made in Austria no less. Maybe one of Toto’s relatives. 😁 Hope all’s well Dave 🍀
Could you make a video showing how to get into the machine without destroying that outer case? I have about 4 of these and they are all dead and I am hoping that as you uncover how to fix it I might be able to work on mine but can't figure out how to get in safely.
There are two fasteners hidden under the handle you may have missed. 🍻
If you can pull the transformer and you’re not getting any secondary
See if there’s any printing on the transformer to tell you what the vulture should be in the secondary that you’re not achieving
Disconnect the transformer, and use your own power supply or variety to supply the secondary that is needed .
Bypassing the power supply and use a third-party power supply to activate the machine .
And then go back and diagnose the power supply later .
When you eventually get that far, and if you do determine something wrong in the power supply, do a video on that all by it
Checking out those capacitors that are electrolytic ?
Yeah…Seems like the primary winding of the transformer is open. Doesn’t appear to be any secondary voltage output and there are multiple secondaries. Will be difficult to substitute a generic transformer as I have no idea what secondary voltages are required. As mentioned the motor and transformer appears to be a single sub assembly. Likely purpose built. Anyway, nothing confirmed yet. Further disassembly required. Really need a schematic, without it this will be very challenging indeed. 🍻
@@TheGibby3340 There’s a simple formula I used to know, but don’t anymore
You take the Ohm reading of the secondary windings .
You measure the gauge thickness of the secondary winding.
And then you follow the reference material that tells you how many feet of a certain wire give you a certain ohms when you feed it will give you your X voltage
That’s for calculating length. Mathematics involved for calculating number of turns in the primary & secondary’s honestly is way beyond me.
@@TheGibby3340 you can also figure out the voltage
Because there is a way to figure out the turns using two of those formulas . .
That’s why I was a DNF student in Electrical Engineering, class I can never remember the form
Horrible at remembering how to use them even when they were presented right in front of me
But still enjoyed the classes. Look forward to going back. I was only the third semester of Electrical Engineering, when Covid hit and shut down all the colleges. .
And I have never returned since .
I need your contact please. Thanks
Well since you don’t need this to process the film cartridge anymore… just take your movies out of the cassette and reel them onto a super 8 reel… and you can project them without this contraption… if doctor land had just made polavision self developed super 8 film without all this crap… it may have been much more widely accepted
