I'm thinking about doing a follow up video on design... Form vs function Because the I-1 truly has some decisions that must exist only to break the mould
by the time the i2 came out the old non replaceable batteries in the i1 are more or less 1/4 of their usable capacity at best. not to say planned obsolescence because they never would have guessed they would last long enough to make an I-2 (though the naming convention suggests otherwise) but non replaceable rechargeable batteries are very convenient to make sure your hardware is replaced when the battery dies
I was also in a very difficult situation due to the sudden battery death. I thought about taking the battery to a professional repair shop and having it replaced, but I hesitated because I expected recurring expenses. Thanks to the video, I think I can save my dead camera. Could you please tell me the exact model name of the JST connector?
@@theinstantcameraguy Thanks for answer. I know from watching the video that it is a 2pin jst connector. However, when I searched for products, various detailed model names came up, so I asked just in case. Anyway, I just buy a 2pin product and give it a try. And my product had two 500mAh batteries connected. Even the detailed battery models are different... It looks like they really recycled the excess batteries that were sitting in the warehouse.
@@nirvanaspero going on eBay and searching for 2-pin JST for me yielded results And I purchased a large multi-pack of various connectors from my local electronics store, that have all kinds They are very universal
@@theinstantcameraguy sadly... the 900mah battery i bought was Instead of being thin, it was larger and I couldn't assemble it. lol i was only worried about the jst connector, but the problem actually lay elsewhere. i will succeed and come back.
Can't believe I didn't think of just using JST! Gonna give this a try, might just mod it to have an actual on/off switch too, the battery drain when "off" is ridiculous. RE the weird design choices, is it possible they just knew it was a mess and kept things weirdly modular right up to the last minute? The PCB and the viewfinder both seem so terrible that I can easily believe that.
it's probably possible to add a small on/off switch inside the door assembly somehow The issue is, I think the camera will forget all its settings etc if you cut the power, since film counter, darkslide eject etc is all controlled electronically
I know of two iterations of the I-1, it seems like you have the second kind. The first version does not have the light shield in the lens opening, while yours actually has it. The light shield looks like a flat sheet of black with a hole cut in it. The first iteration actually shows the quintic lenses and the clear plastic gears. It must've caused some unwanted light refraction, but it looked really cool(again, aesthetic trumps function!)!
had this and rapidly went off it due to the poor viewfinder, confusing led lights on it and then of course realizing the battery lost charge when not in use ? Hard to imagine polaroid still make their cameras with non replaceable batteries!
@@theinstantcameraguy yes you probably won't see an immediate difference. Without measuring peak current draw whilst ejecting and comparing the data sheets of the batteries used it's hard to say if one cell would be rated to deliver the current needed or not. But a new healthy cell would probably mask this, just over time as the cell weakens it may develop ejection issues faster than two cells put together. My guess would be that whoever designed it found that power consumption could peak just a bit above what one cell was rated for, and the easiest solution at the time was just to double up smaller cells
@@burntoutelectronics with the JST connector I installed at least the battery will be easy to swap :) I should note that with the ejection issue cameras I tried to refurbish earlier in the year I tried all kinds of cells. Single, double even hooking up an 18650 temporarily. It didn't help :(
@@theinstantcameraguy their original design of having the battery and camera wires going to the same JST plug boggles my mind. Good thing you've sorted that for future replacements. A weaker cell should just make the motor run slower, I've got no idea how the ejecting timings in the I-1 work, whether it's time based or that sensor you pointed out does all the trickery or what. When a camera is malfunctioning, does the rollers always stop at the same point?
@@burntoutelectronics ejection timing is controlled by a cam on the rear gear of the roller assembly. Effectively it turns one full resolution for one ejection. At a certain point the cam depresses a switch which tells the motor to stop. It's a very simple solution, and because of the cam, there is no need to align or 'time' the gears. You can remove the gear and put it back on in any position, and it'll always engage the switch after the same period of time. The cameras with ejection issues cease ejection around 3/4 of the way. I of course could be wrong, but from what I can see this issue has nothing to do with the switch, and seems to be a case of the motor just conking out 3/4 of the way through the cycle, as if its overloaded the circuits and shut down. The internals of the camera are super hard to access and VERY complex inside. I have no idea if its some kind of failsafe thats prematurely activating, a failed component or what's going on.
Saturday night 3AM
I was just going to bed but this is a great reason to stay up even later 😅
I just want it on record that the day the ejection issue is solved, will be one of my favorite days
Mine too
A good and informative video, just too short for me. Awaking at 3 am here, it was over by the time my tea wasn't too hot to finish.

Google JST connector socket and buy the one with two pins...

Not that you point this out, you are absolutely correct
This could also go hand in hand with the screw vs plastic lug on the motor PCB
I saw a guy in the US who's selling a self made viewfinder for the I-1. Maybe you could also convert one from scrap parts from a box type Polaroid?
If I ever get myself an I-1 to personally use I'll consider it
I'm keep looking at that USB connector and wondering if it can be "upgraded" to C
Not easily that's for sure

The only reason cells would be paralleled would be for increased current delivering capabilities
I've tried both solutions... And it doesn't seem to make any difference in how the camera functions

Ordered batteries, only place was Ali Express😢
