What is the location to get analyzed spectral data in [wavelength, intensity] at at the SpectralWorkbench/capture page?

by Reallygeek | almost 7 years ago | 0 | 0

I've never really used API's before, so forgive me if my terminology's wrong.

I'm looking to get real time data of the intensity of wavelengths for a robotics program.

Thank you.

Noise when Trying to Analyze Spectrum

by matthart610 | almost 7 years ago | 1 | 0

This is my first time trying to use this and the images I had taken from my phone of the diffraction pattern show only noise levels when looking at the intensity vs. wavelength? Any suggestions? Is the slit too big, do I need a better camera, is there possible excess light bleeding in?

Here are the images of the calibration and a tungsten bulb:

how to export data from the spectral workbench capture site?

by Reallygeek | almost 7 years ago | 0 | 0

I'm try to get real time data of [wavelength, intensity] from the "https://spectralworkbench.org/capture" page. I want to export that data and import it to an arduino script for a robotics project.

Does anyone know where that data of [wavelength, intensity] gets stored/ what's the variable name?

Another idea I had is creating the data as a CVS file and exporting that. Does anyone know anything about that?

How should i go about converting svgs to jpgs or pngs

by Flameytail | almost 7 years ago | 3 | 0

I am using this tool co calibrate fire test colors for our schools science fair. I need to create a science fair board and i need to print out the readings. i dont need it to be super accurate just to have a definite measure- ability. i am extremely new to this so dont judge

that is the lab procedure that i have created

1. Configure the spectrometer box(acording to the included instructions)
2. Go to Public lab Spectral workbench and click the "Capture spectra" button in the top right corner
3. Make a account with public lab. A real email is not necessary(no verification required)
4. Plug in the USB cord to a USB port on your computer
5. (I am using Chrome web browser for this experiment so I do not know how to configure the Safari or Internet Explorer version of this) Locate the camera icon in the top right corner of the search bar.
6. Click on the symbol and change the camera to the spectrometer module that you plugged into your computer.
7. Place the spectrometer module in the test tube pincher attachment, with the camera farthest into the clamp and the lense pointed at the blowtorch . If needed apply tape to the module and the holder till firmly attached
8. Use one a seperate clamp to hold a thermometer into place in the flame of the blowtorch
9. Fire up the blowtorch
10. Make sure that the Nichrome wire is free of contamination by heating in in the flame till it turns bright orange
11. Quench the wire to make completely sure that the wire is free of contamination
12. Click the button titled
13. Scoop around 200 mg of copper sulphate up with the nichrome twist. To non scientific measuring that is a small pinch
14. Place the wire into the flame and click the start recording button
15. Save the spectrum recording as the chemical name to your public lab account.
16. Calibrate the sample by clicking calibrate on the main bar
17. Adjust the bars that apear on the colored bars on t bars of color that you have captured
18. If they do not need any adjusting save the image.
19. Create a folder in your desktop titled "Spectrometry Samples"
20. Download the file as a image and create a document with all of the images on the documenti

ive probably messed a few things up so

Power & connectivity error messages with DSK 3.0 Cameras

by Bronwen | about 7 years ago | 0 | 0

(posted on behalf of a new user)

The camera that came with our original Spectrometer 3.0 kit worked fine with our MacBooks (Model A1342) running OSX/Windows 7. The camera included in the kit was the EPC2MB Ver: 1.00, dated 2014.11.04. The 46 Spectrometer 3.0 kits that we ordered came with the JDEPC-0V05 Ver: 1.00 camera, dated 2014.10.24. When we plug these cameras into our laptops, we get a "This device can perform faster" error message in Windows. The camera shows up as an option when using Spectral Workbench, but there is no video displayed. By plugging the camera into a powered USB hub (a hub that gets its power from an AC adapter), the issue goes away. When we use the cameras on the OSX side, the camera is detected by Spectral Workbench but there is no video (just like in Windows). Again, the issue is resolved by using a USB hub.

Why can't I calibrate? Glitch?

by hanswilms | over 7 years ago | 4 | 0

I'm trying to calibrate my minispec, but everytime I click to "Save" on my calibration, the save button just turns into the loading circle and never stops. Happens on both Chrome and Internet explorer. Is there a non-HTML version I can download or something?
