The Landingfield 
Hi to he Landingfield !
I am a french student in neurosciences, and I am writing a vulgarization article to compare the retina and cameras. I would like to use two of your pictures. Could we get in touch please ?
Best,
Thomas
Hi Thomas,
You may use it freely as long as you provide a citation and a link.
Hi, I’m creating a presentation (to present to my tutor group) to explain how Charge Coupled Devices work. I think a couple of your images would be perfect. If I provide a citation and link, may I use this image?
Cheers,
Sam
Yes please, go ahead!
Hi Jack, I envy your works and I’m intrigues with your camera mods, are you available to chat, I have some
Similar work I’d like done and would like to have you consult with me with payment to you.
What is the best phone number for you so we can chat for a minute and see if this is desirable.
Many thanks
Paul
Sorry I’ve been busy and missed a lot of messages. Please leave your email here and I’ll reply back.
Hi, thank you for your reply .. my email is pwx444@gmail.com, please reply to me… if you don’t mind please email me your phone number and I will call you to chat for a few moments. Thanks
Hello,
i am using a translator so sorry for my english …
I use a D5100 for astrophotography (https://www.astrobin.com/users/archcam/). I currently use a coldbox, but I would like to do some tests on the cooling of the dslr. I saw that you have found the PTP command with which to read the sensor temperature value. What command are we talking about?
Corrado
Hi, it’s a build-in test command from factory calibration tools. We extracted it and run that in the hacking suite a long time ago. It’s quite a challenge to implement that in standard libgphoto2. We need to alter library funtions.
Hi, I have been trying to revive an old 35mm film reel camera of my father’s. I have used Raspberry Pi Zero along ( https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/ ) with its HQ camera module ( https://www.raspberrypi.com/products/raspberry-pi-high-quality-camera/ ) to make things work.
Even though the camera is working now digitally, the problem is that since the sensor is really small, the images are a bit zoomed and it’s really wiggly, I mean even breathing is making the image hazy due to movement.
While googling, I found your camera project, I was hoping you can kindly guide me through this…
“wiggly” – Are you referring to rolling shutter effect? I have not used ras pi camera due to its limited IO/bandwidth. If you want mechanical shutter to work with rolling shutter, synchronization is the key.
Hi Jack,
I’m very interested in reproducing some of your work on the nikon D850 sensor. I’ve got a couple fpga dev boards laying around that would fit the bill. Are you releasing your source anywhere? As I can’t seem to find any reference to any of your board designs or source codes anywhere. Would it be possible for me to get access to any of this material? (for personal non-commercial use of course)
Hi Oscar, unfortunately I do not plan to release the RTL code as many IP I made were for other projects. But I could build FPGA image for you if you provide pinout/IO mapping to your FPGA board. What dev kit do you have? Are you willing to layout the IO breakout board to suit your custom dev board?
Hi Jack,
It is understandable that you won’t just release your rtl. Are you willing to share some protocol details and the schematics of your converter board. That would be enough for me to write my own RTL. A lot of the details are already documented nicely, but I’m talking about stuff like registers and addressing.
I just found your email message. I’ll reply to that.
So I bought a damaged d850. It was almost functional when u bought it. Then I took it apart. So now I am wondering if I can use the Sony IMX-309-AQJ and build a drone camera for photography. Or. If u still have the z, the sensor is the same lol. I tried to read the article but it’s a little over my head. If you could let me know your thoughts I’d appreciate it. Thanks
I’m not sure what exactly you want. Directly dump raw image?
One thing I thought of was a dedicated astrophotography camera.
Hi jack, My name is CHEN Pei I want to y dump raw image from aps size camera like sony a6000, do you think it is possible with your fpga design? Please give me some comments to cjhien@163.com
Hi Chen, according to my camera archtecture spreadsheet, your A6000 should be using the IMX210 sensor and has 12 lane subLVDS interface. So yes, that’s certainly possible
Hi, we are trying to make a cooled camera using the IMX309AQJ sensor. But, now we can’t find the datasheet. Your scheme should be the only way to work it out. Would you like to provide the technical information of the sensor interface?
We are from China. Many people in our astronomical circle try to make refrigerated cameras. They use CCD sensors instead of CMOS sensors. We have a low-cost solution to avoid Dewing by using vacuum, and We can spend only about $100 to purchase the sensors of D850 . We hope you can provide technical information about the interface of this sensor. I are confident that we can solve other problems, we can cooperate to make the first CMOS cooled camera made by enthusiasts.

Hi, I want to build astrocamera using imx071 from Nikon d5100. Could you please share information about this sensor (for example protocol, registers, pinout, schematics). I want to write my own program so I would be grateful if you provide information about the interface.
My email is supermmassivve@gmail.com
Hi John, For IMX071 all the register setting is already available on the NikonHacker Wiki. Go to https://nikonhacker.com/wiki/IMX071. I didn’t hack the pinout, just used the original sensor module.
Hi jack,
We are working on an artist book and would love to reproduce some of your close-ups of bayer filters.
Could we get in touch to discuss rights/credits please?
Hello Jack,
I tried to leave a comment on one of your blog posts but I don’t think it worked!
I’m a fellow camera enthusiast and embedded systems engineer working in the space industry. I love your work and never thought it would be possible for someone to achieve what you have with these sensors. I’m currently in the process of making my own fully featured hand held camera which is nearly complete. You can see the ‘blog’ I’m writing here for it although I haven’t updated it in a long time. https://docs.google.com/document/d/1gnEBzrgK05kzuTFEPspbsJ127sbl_kKvJMLyx1T–wY/edit#heading=h.vmkrgwd2xs0f
For my next project I would love to use a full frame sensor thus finding your blog has been huge in unlocking using these large sensors. I wonder would you mind sharing some information you have about them? Perhaps we could talk via email. I might be able to share somethings with you as I have many datasheets for industrial Sony image sensors and a good relationship with GPixel and Framos.
Many thanks!
George
Hi Jack,
Running on ecp5 serdes’es with a similar sensor here. Is your SLVS core tied to a Xilinx implementation or does it manage its own input / clock recovery / deserialization? Typically to run on a FPGA without a hardware serdes ?
Hi David, this SLVS-EC core is a specific design on Xilinx HPIO/HRIO architecture. I handles phase recovery, decoding, depacking using soft logic. The phase recovery has some hardened Xilinx block. The rest should be portable to other FPGA. But it requires IO speed to be comparable to Xilinx’s.
