Counting grains, measuring reporting and sharing their properties globally

Hello Ask USDA, I am impressed that my question was processed over the Christmas weekend.  I have been reading more about grains, grain quality, grain grading, grain cleaning, grain sorting and related things.  I still have not found reports that tell the number, sizes, weights and qualities of grains. The closest is things related to

Comment on Color Sorting Grains video

Bench Industries Portable Color Sorter at https://www.youtube.com/watch?v=b_ZmpyvZKp4 It looks like it is also possible to sort by protein and biochemical content. Whether that can be done in real time is probably only a matter of cost and programming and FPGAs. I just read about sorting of colored rices where the evaluation was done, not on

Machine vision and Industries – ZWO group on Facebook about microscopes and noise imaging

David, The lens is usually a fisheye or other lens with 1X magnification. You have to add it to a microscope meant for a human eyeball. A decent microscope is expensive and odd shaped for humans, so it does not fit in an industrial or lab or security environment. What I want is a 10x

Comment on old style MIT lab presentations. They are SO slow

Optics: Fringe contrast – path difference | MIT Video Demonstrations in Lasers and Optics https://www.youtube.com/watch?v=IZGnYe7BUms This is like those old serials – always ends with a cliff hanger. How irritating. Some good stuff, glad to see it. But wish he would not be so Socratic, and more measurement and data oriented. But this is a

Comment on Making Petrified Lightning – application to solar system colonization, global needs and new industries

TheBackyardScientist,  Making Petrified Lightning …with electricity? at https://www.youtube.com/watch?v=m7YznIKe7bU 3D printing metal. You can use metal or glass powders, control the current, and randomly choose next points – probably run on Arduino. You have all the skills and stuff mostly. Maybe someone already suggested. You might invent a way for YouTube viewers to work together, combine

Contact Imaging Sensors, Linear CCD arrays for gravitational and magnetic imaging

Jean, I was trying at least two pathways: 1. Build circuits to read the analog signals from these linear sensors, and put the fastest and best ADCs to read and store the data. The focus on high precision measurement of the signals as a function of reference voltage. 2. Somehow learn to talk to these

Comment on plasma cutting video by Jason Michael Saunders, referring to 3D printed rockets

Comment on YouTube Jason, I watched this Genius of 3D Printed Rockets video the other day. They are using plasma discharge heating, but it is not very well controlled at all. They say “it works really precisely”, but it throws off heat and light and bits of wire, and fluctuates a lot. It only needs

Looking for low cost linear arrays of photosensors, maybe contact image sensor arrays

Jean, I want to find a contact image sensor CIS that has high dots per inch, large color depth (bits per pixel color) and fast speed (lines per second). I need three of them, and don’t know where to buy the parts. I just started looking and found that the mobile document scanners (Brother) seem

Comment on video to measure wavelength of sound and apply reasoning

Waterloo Double Slit 1 at https://www.youtube.com/watch?v=acgb5uP4CBM David, I think it would help viewers if you draw a wave on a transparency and overlay it onto another wave to show what is happening. Put two arbitrary time series and look where they match or do not as the time difference changes. Put a time series made
