Just asking, do you have any intention of building/selling such a board? Id love to make my own m43 camera.

What about availability of the 283 based boards? I see they are out of stock now. Thank you

I'm still debating about building a batch of this board, the main reason being that raw sensor cost are too high while you also need a certain amount to average the cost. (Not saying that I need to do 100+ but even with 20 boards, that means at least I need to put 2400 USD down just for the raw sensors). I don't think I'm gonna able to sell any of them at 399 USD and at this price it feels too risky for me.

While on the same time IMX294 is not that interesting for me personally (Resolution being the biggest issue, I want to have ~2.4um pixel size to match my telescope), I've also read the comments at Cloudynights and the response doesn't look that promising as a astrocamera either.

So in general I do recommend to build this board yourself if you are somewhat familiar with PCB design, I'm sure it will be faster then waiting for me to put it on the store.

As for the OneInchEye I'm planning to do another batch later this month.

hi What about imx294 availability ? Where do you find it ? great project btw ! G.

I'm very interested in this. resolution could use work, but I'm super curious in building my own m43 camera. I don't mind ordering and populating the boards, but where can i get that sensor?!

Also asked about sourcing the sensor on twitter without answer. Please share your information!

Are you still planning on doing another batch of the oneincheye? I have checked your tindie page a few times with no luck.

My main interest was to make an ICL camera using a cm4/cm4nano carrier, so I liked the idea of a m4/3 chip. Are there others that might be cheaper that would work? As for astro, I also am an astrophotgrapher, and used to have an ASI ZWO 294MM. It's a weird chip. I ended up getting an ASI 2600MM with an IMX571. That would make a great still camera! but obviously for even more expense. If you have at 294 already made you could use binning which works great. I always used the 2 or 3x bin with my 304mm RC telescope, but I even did some planetary photos using full resolution and ROI.

+1 on a 1 inch eye. It would work great for an initial experiment with a C mount ICL.

What's ICL?

Fun fact - you can find IMX571 datasheet too, the only issue I'm facing is how to capture the SLVS-EC.

I have a CM4 camera module board used here: https://www.willwhang.dev/SolarImaging/

@gehelem did you find where to source the imx294 sensor? I'm currently looking for it. Kind regards an aspiring engineer
