A one year doubling rate would be extremely fast by industry standards, and if you put it in space it does not need to be very energy efficient at all. 23:28 < nmz787> I've been studying whatever I can in my spare time lately on the deflection coil high-voltage controlling an electron beam 23:29 < nmz787> so I can try to get my SEM working 23:30 < lsparrish> Freitas Atomic Separator Replicator is kinda cool. http://www.molecularassembler.com/KSRM/3.14.htm 23:31 < nmz787> yea, we've talked about that in here a bunch 23:34 < xtalmath> lol, what would happen to all the uranium being sorted together? 23:35 < lsparrish> Hmm. Maybe just sort that into very thin rods. 23:35 < nmz787> err, I guess we've talked more about Freitas atomic assembler 23:36 < lsparrish> Yeah, the macroscale ideas don't get as much press. 23:37 < nmz787> isn't that basically just a solar-powered ion-implant machine? 23:37 < nmz787> seems just like a mass-spec with a deposition system 23:37 < lsparrish> His numbers: weighs 120 tons, processes 1.25 grams per second, uses 11 MW of energy, and replicates once every 3 years 23:38 < lsparrish> yes 23:38 < lsparrish> it's a huge, inefficient monster of a system. 23:41 < nmz787> anyone in here in phoenix, AZ? 23:41 < nmz787> and also an EE? 23:41 < xtalmath> I think cheap diy microfabrication tools is the best bet for discovery/invention/innovation 23:42 < nmz787> I had some ideas for a laser lithography tool using a microscope and video feedback of a grid of dots moving offset from the lasering-area 23:43 < xtalmath> nmz787 can you elucidate? about the grid of dots? 23:45 < nmz787> just so you can track where you're at... and the dots should have a high-resolution accuracy to begin... such that you can watch the dots in the video, know where in the XY plane you are, and also know if you need to speed up or slow down the motors because the screw position you're at is longer than it was a moment before 23:48 < xtalmath> on a 2D galvano mirror with flex hinges, theres typically 2 mirrors, one on top for the power laser beam, and a square on other side, a led shines on the bottom mirror, and the square beam reflects on a quadrant photodiode, so that the signal is proportional to deviation 23:49 < xtalmath> this way the system knows where the mirror is pointing at 23:50 < xtalmath> I just read about this in a book called "practical opto-electronics" by protopopov ... 23:50 < nmz787> huh 23:51 < nmz787> I guess my thinking was that microscopes are pretty common 23:51 < xtalmath> yes, microscopes are 23:51 < nmz787> so something that could ride on top of that might be nice 23:51 < xtalmath> in theory, all you need is an inspection objective 23:52 < xtalmath> they have a beamsplitter, so one can insert a beam, but not sure what powers we are speaking of, and if it would damage optics somewhere 23:52 < xtalmath> oh and the 2d deflection mechanism of course 23:53 < nmz787_i> ah, well i was thinking offset so you could just use a bluray drive writer head unmodified optically, just connected to a power controller for the beam diode 23:53 < nmz787_i> they have near-TEM00 beams 23:54 < nmz787_i> at close to the diffraction limit 23:54 < nmz787_i> and also quite common 23:54 < nmz787_i> moreso than microscopes I guess 23:54 < xtalmath> that is a good idea, I wonder how far their focal point is from the lens? 23:54 < nmz787_i> but at least they are the part that would wear out more 23:54 < nmz787_i> pretty close 23:54 < xtalmath> seems problematic 23:54 < nmz787_i> like half a millimeter I think 23:54 < nmz787_i> not for litho 23:55 < nmz787_i> and that's only for the smallest spot size too 23:55 < xtalmath> then how do you get feedback from the microscope? 23:55 < nmz787_i> http://diyhpl.us/~bryan/papers2/optics/photolithography/High%20resolution,%20low%20cost%20laser%20lithography%20using%20a%20Blu-ray%20optical%20head%20assembly.pdf 23:55 < nmz787_i> raspi with camera and 120FPS I guess 23:56 < nmz787_i> idk, might be too slow, and you just have to calibrate once with the grid 23:56 < nmz787_i> scanning with the camera in video record mode along the x and y axes, to correlate and setup a table of position corrections 23:56 < xtalmath> thanks for the paper! 23:57 < nmz787_i> but then in that case (the lookup table of corrections) you can't account for a motor skipping steps (if using a stepper) 23:57 < nmz787_i> I don't think that would be a problem with a DC motor though 23:57 < nmz787_i> though I'm not sure 23:57 < xtalmath> I mean, how do you view with microscope, while the bluray module is in the way? 23:57 < nmz787_i> (since you can be sure to reliably pulse a DC motor) 23:57 < nmz787_i> oh, just slap it off to the side 23:57 < nmz787_i> 'slap' -> mount 23:58 < nmz787_i> it would be a constant offset from the video 23:58 < nmz787_i> but the video would only be used for feedback or calibration... and otherwise used as a normal microscope 23:58 < nmz787_i> maybe for inspecting what you just lasered 23:58 < xtalmath> oh, so the video is for position feedback, not for monitoring the pattern as it is being burned? 23:59 < nmz787_i> or if the colored fluid you are trying to pump through your lasered and developed and processed microfluidic is working 23:59 < nmz787_i> yeah 23:59 < xtalmath> ok I see, thats interesting 23:59 < nmz787_i> you can monitor the beam current 23:59 < nmz787_i> and a lot of laser diodes have built in photodiodes for brightness feedback 23:59 < nmz787_i> since the laser photo output changes with temperature --- Log closed Fri Jul 31 00:00:09 2015
