A very neat project Andrei. I kept wondering why you chose the Mega. I'm glad you explained it was because using the Mega made that display a lot easier. I learned quite a bit more about light and spectrometers. Thanks for sharing.

Very nice for Optical spectrometer but there is also a pc and apk software that make diy spectrometer easy using just DVD groovs and camera . But I asked you several times to also make Wide band RF spectrum analyser using easily available wide band RF modules . Now days everything becoming digital and controlled by just one pack chip so young generation is not able to find technical details and knowledge RF electronic is one of them but for that they should have at least one instrument which is Spectrum Analyser I know there is also other options like Sdr but building scanning based spectrum analyser is much Informative as it cointains lots of important radio technology like superheterodyne circuit etc and even FFT based is very unique because FFT is very Important algorithm for mordern age .

Off-topic question: since light is an EM wave, why can’t we measure electric current when we shoot light through a coil of wire? Why can we only detect it when it hits something like a ccd camera?
@narayanbandodker5482
Жыл бұрын
I just realised that radio waves are detected by the coil, so maybe it has to do with wavelength or something

I like how you did your optical setup. Times like that, I wish I had a 3D printer! (But nowhere to put it in our tiny house.) One thing I didn't understand is, you kept saying you were going to "load the code from below." But what the heck does that mean?! I really don't understand. EDIT: Wait, were you talking about "download" -ing the code? Is that what your think "download" means?! Ha ha ha, that's funny! Is that it, really? LMAO! Sorry, I just thought of that after I wrote my question. But is it true? It must be--you have so much trouble pronouncing everything, so that's the only explanation I can think of. Maybe you should try listening to people actually speaking English, you might learn a few things. Although I will say there's probably not many people who can pronounce "spectrometer" correctly anyway, so you'll have a long wait, lol. I'm not trying to be mean, really. Just sayin'. I do like your projects. I just have a little trouble understanding you sometimes. Excellent project! You covered a lot of concepts. By the way, the prism doesn't "speed up/slow down" the different light frequencies, it diffracts or bends them, according to how the wave hits the interface. You can't really change the speed of light. (Also your graphic with the prism was wrong-- the bending occurs at the interface of the media, not in the middle.) 👌

Hi. I need your help! In this video kzitem.info/news/bejne/1Wh3rqdqapNiloo , in the transmitter code you say that these values mapJoystickValues( analogRead(A0), 13, 524, 1015, true ); they have to be measured. How are they measured?
