How I Greatly Improved My Cheap Microscope
In this video I take my old, cheap educational microscope and extensively upgrade it for better usage and video-making capabilities. I add an xyz stage, a 2K digital camera running at 10 to 15 fps, and an epi-illumination assembly to give the microscope the capability to do reflected-light microscopy. Since all the upgrades are completely DIY, it is also possible to continue upgrading it for other types of microscopy like dark-field or polarized light microscopy.

    just a small thing it is physically kinda impossible to go much under 500nm with light microscopes because your light wavelenght is literally maxing out in that range. you are pretty much at the edge of what a normal light microscope can deliver.

    • @BirdbrainEngineer
      @BirdbrainEngineer 6 วันที่ผ่านมา

      With no extra tricks, optical microscopes can resolve objects as small as half the wavelength of visible light, which means it would be possible to make out features down to about 200-250nm or so. So, technically there's still some ways to go, not to mention having worked with it a bit by now, in practice, without painstakingly finding the most optimal z height and all, I am only able to resolve features down to about 500nm (with the 40x objective that the microscope came with)... beyond that it's really a chore to really see anything on a real IC for example.

    I really like the stepper motor controlled bidirectional stage. You could do the same with stepper motor and a higher pixel camera for focusing so the stepper motor is controlled by software that determines when an object is first in focus, takes a photo, then incrementally focus further down in increments and taking a photo at each focus increment until the object is just out of focus then stack the individually focused photos.

    love the video. quick q tho: at 10:4 i am unsure why the sum goes over i. I get that you convolve a select channel j per each kernel k. Then you take the growth function of the result. for each Gk you multiply by a weight coefficient Wk. each weight belongs to one channel i tho, you do not sum over all weights, right? (also otherwise the indicies dont really work out)

    • @BirdbrainEngineer
      @BirdbrainEngineer หลายเดือนก่อน

      I am not good with mathematical notation, and I do remember that while making the video I was not sure how exactly to really represent the whole algorithm, but I guess you might be right that the i does not belong under the sum there, as the result is for the i-th channel in the first place. My mind works much better with algorithmic way of thinking rather than with mathematical notation... I straight out get a headache every time I need to make sense of mathematical notation in papers for something haha.

    Could we directly use the spin coater on windows instead of the homemade graphical interface ?

    • @BirdbrainEngineer
      @BirdbrainEngineer หลายเดือนก่อน

      I am not sure what you mean... Do you mean if it'd be possible to interface the spin coater to a PC running Windows? If so, then the answer is that technically you could, but one would need to write quite a lot of extra code to facilitate some sort of protocol to talk to a program or webserver on the PC. If you mean that whether the spin coater itself could run Windows, then the answer is no; the hardware is far too weak for that, and even if you used a proper raspberry pi to run say Raspberry Pi OS (Linux), then you'd technically lose the RTOS capabilities of dedicated hardware, which may or may not work out.

    the gap created by the print between your windings and the laminations probably causes a lot of reluctance. reluctance motors in general are lower torque and are more sensitive to air gap also. for your KV: you should do the opposite test, drive the motor at a set RPM and measure the output voltage under open circuit

    pretty cool but is it possible to build a computer in Lenia that runs Doom.

    • @BirdbrainEngineer
      @BirdbrainEngineer 2 หลายเดือนก่อน

      Someone already asked that some weeks ago haha... The answer is... Both! A certain Lenia ruleset can simulate Conway's game of life, which is Turing complete, therefore in that case Lenia itself is also Turing complete and could compute anything that could ever be computed, including Doom. At the same time, there are some rulesets that are trivially not Turing complete (eg. The ruleset that would simply simulate diffusion/blurring). For any given ruleset, there is no known way to easily tell whether the ruleset is Turing complete or not. If somebody could figure it out, it'd be extremely big news and very useful outside of the field of cellular- and continuous automata as well.

EDIT: also Im just curious and i doubt this comment will get seen but how do reluctance motors induce a back emf/ resistance of some sort to the input voltage. all motors of some sort have some sort of back resistance because as rpm increases output power increases and thus input voltage and current draw should also change. or if there is no back emf or anything how would a motor like this work or what shape power chart would it produce?

      Yes, the Raspberry Pi 3 is what I had laying about and unused. As for using the Zero... I'm not convinced it could handle the stream at such a high fps (maybe the Zero 2 could), plus the stream over wlan is going to be a concerning proposition compared to just lan. I did try to stream over wi-fi in this case too, but it did have some problems... but that could simply be because my router is kind of far from the microscope and the signal quality isn't really the best it could be.

      Yes. At 1080p you can easily get 30fps, 60 might be difficult but iirc the Raspberry Pi cam 3 is able to do it technically. You will certainly need heat sinks on your Raspberry Pi though, as the streaming is quite demanding, even with the heat sinks shown in the video, the Pi gets up to like 60-65C.
