I like the music choice!
Witcher Music in the background, WOW
I downloaded the stl's and they had to be scaled by 2510 to get it close to size in CURA 5.6.0 to fit the phone holding piece and had to mirror image it as well to fit my phone. CURA actually scaled them 1000 on arrival!
love this video. and epic voice.
Near Slit , What is there ??? Diffraction grating or Mirror ?How to select wavelength for this caase? for example 400-700nm for analytical analysis of chemical solution or dye /Where you had connected DVD Diffraction grading? Have you connected the mirror? At the edge of the slit? Or you have connected in front of the camera-Lens?How to get absorbance -wavelength curve for a cuvette
How to Calibrate the Device? Means ROI of Image EM Visible Spectra. Does it give emissions? Thermino?
I love how you even mentioned that we need a cup of coffee-- I'd really need one to get through this project lmao

Hello, I'm using your video as my reference for my project. I wonder how did you make the spectrograph from the values displayed in the app? Thank you
Basically I draw a graph using 3 known concentration solutions. For every measurement I compared the solution with a 0% (only the solvent), to compensate for the cuvette. With the 0% I've "zeroed" the app (Reference option in the app) and take the measurement. I picked a frequency to use for all measurements.
I've added all tree values to a graph (concentration / light dropp) and connected them with a line.
When you measure a unknown concentration, now you can compare the dropp to the graph and get the value.
If it doesn't make any sense let me know and I'll make a separate video explaining and demonstrating at the same time. "See you" later.
@@beermoneylab7492 okay, I'll try what you said. Thank you again
@@beermoneylab7492 hello could you make that video

Cool project! I have a few questions:
1- Interesting voiceover, what software did you use? Are you not confident in speaking English? Or are you an AI in totality?
2- Does the Theremino software already know the frequency response of a handful of cameras, including the one you used? It seems you would need to make some major calibration adjustments otherwise.
3- What music did you use? It sounds like a chilled down Kitaro, from India.

Can you please link up the camera used in the video.

Thank you very much for sharing this interesting info and video. I have just few questions. 1-Where can I get this tool? Could you explain about the software? How can I determine the exact wavelength and absorbance of the various concentrations? 3-Could you clarify the wavelength selector in more detail? We can replace it with a normal CD.

Umm. Nice Witcher music. I'd like to take a look at your wares.
I could hear this in Geralt's voice.

I downloaded the stl files. But all files look he same. Am I missing something here? Do I need to print any one of these?

Hi could you publish your files of this spectrograph as I would love to recreate it
Hi.
The spectrograph it is adapted to work with a Microsoft LifeCam Studio web camera.

@@beermoneylab7492 I was wondering did you do any modifications to the camera?

cheap LED light can't replace sunlight at all. Your scheme says "sun light" and this is right, cheap led light is wrong.

@@techpiku1Too many questions. Seems you still need to learn a lot, before build one. It will be simpler for you buy one, or go to lab, or ask engineer to build one for you.
Asking for that software for absorption analysis
