Re: Making a DSU from scratch for an orphan DCS100

Hi everyone, I owe you an update on the state of this project. It's actually on pause, life got quite busy and the DSU came to a difficult moment (at least for me). The way I was caching data on the FPGA proved to be very jittery and ends up corrupting the image, so this was discarded. I wanted to u...

Re: PSA to everyone with a vintage Kodak (and a nice story too)

So the PSA... Recap your Kodaks, if the caps haven't failed yet, they will fail sooner than later. Also, electronic devices are meant to be used, being on a shelf makes more damage to them than being used, so if you found a "New Old Stock" "New In Box" or something that implies t...

Re: PSA to everyone with a vintage Kodak (and a nice story too)

Not a tantalum on sight for the power rails, the shutter fired, voltages were all fine, everything seemed normal, time for a real test shot. https://i.imgur.com/wDyc4SB.jpeg Nope... more troubles... There were some tantalums left but were used for specifics reasons on each circuit and yes... one of ...

Re: PSA to everyone with a vintage Kodak (and a nice story too)

Frustration was on a all time high, but this was the motivation to make the thing work... pure stubbornness. On those 3 shot we could get enough info to know that the rail was 15v and used a very common 34036 DC-DC converter mostly following the booster circuit on the datasheet. The only modificatio...

Re: PSA to everyone with a vintage Kodak (and a nice story too)

We expected a very leaky battery on the NC2000 for sure so we rushed to take it apart and remove it, luckily the leakage was minor, we were excited to shoot, grabbed some eneloops and a random battery to get the adequate voltage and we shot a few times... black pictures, all zeroes on a hex editor, ...

PSA to everyone with a vintage Kodak (and a nice story too)

Hi everyone. 6 years ago I came across my first Kodak, an NC2000e, I bought it from a former journalist of one of the most important newspaper in the country. He had quite the collection of his old days at work, among those relics was an orphan DCS DC3 digital back and another NC2000e it mint state,...

Re: Photons to Photos has the SLR/n up now

I just contacted him, i have the 14/n plus an NC2000e and a Finepix S2 that are not listed on the site.

Great website, didn't know about it

Re: Making a DSU from scratch for an orphan DCS100

Well, i'm very surprised on how my 3d printed shutter button resulted being my first 3d model ever, only needed a few minor adjustments (sanding and painting are on the todo list) and is quite a painful to ergonomics but hey, the rest of DCS is also ergonomic as a lego brick so i think i got that fi...

Re: Making a DSU from scratch for an orphan DCS100

Well, not only 3d work has been done, i've managed to fix the internal FPGA caching, i'm still having issues with my clock signal doing weird jumps. I've found that if i replace the statement "if <something> = <value>" for "if <something> > <value> -1" reduces the issue, which is...

Re: Making a DSU from scratch for an orphan DCS100

As most of you pretty sure noted my DCS is missing the shutter button assembly so... why not use it as an opportunity to learn 3D modeling while I think about ways to code what's missing. I'll send my first design to the print shop and i'll post the results. Wish me luck. https://i.imgur.com/ZQqG7DU...

Re: Making a DSU from scratch for an orphan DCS100

AH! improvements at last... inspected every signal, every line of code and it was all correct. Not sure how this fixed it but it did, on every clock cycle I made the FPGA to copy the state of the camera clock to an internal FPGA register and used that register as clock instead of the clock directly....

Re: Making a DSU from scratch for an orphan DCS100

Hahaha maybe gates, that's a really good one. Well adding the pulldowns didn't "fix" the issue of that signal, strangely enough I took apart the DCS to trace the signal till the point I know is correct because it is used in circuit to drive the Horizontal gate (which works as intended) and...

Re: Making a DSU from scratch for an orphan DCS100

Well well well, ignoring that bad signal wasn't the route to go, but having that signal messed up lead me to the problem of not having good clock from the camera, probing around showed me some not so nice signals and decided to check how was implemented on the schematics. Sure enough, i'm missing al...

Re: Making a DSU from scratch for an orphan DCS100

After testing with some actual image i wasn't reading anything coherent and after looking at some signals i found some that didn't look as expected coming from the camera, not sure actually why, they look fine with the logic analyzer but the fpga picks them up quite bad. Anyway, it was easier to ign...

Re: Making a DSU from scratch for an orphan DCS100

Well is not much but is honest work. For the next step i'm doing a small cache inside the FPGA itself so i can format the information and re sync it in order to send it faster than the camera rate so i have some idle time between bursts of data and allow the PSRAM to self-refresh. After much struggl...
