ramanPi is looking for developers!!!

****If you have Python, pyQt4, matplotlib, signal processing, optics, raman spectroscopy or FPGA experience contact dev @ ramapi .org! Or go to dev . ramanPi . org and sign up to the developer forums!

What I want to do:

Build a Raman Spectrometer based on a Raspberry Pi, make it 3D Printable and customizable..

An open source 3D Printable Raman Spectrometer that uses a raspberryPi, a couple of arduino compatible ARM boards, a really bright laser and some parts you can grab from eBay, adafruit, sparkFun, Mouser, or wherever...!

BASIC DESIGN GOALS:

1. Make it Open.. Everything.. All of it..

2. Make it 3D Printable.

3. Make it modular and easy to upgrade.

4. Make it as easy to build as possible.

5. Make it easy to customize and open to improvement.

6. Use only commonly available off the shelf components whenever possible.

7. Have a remote interface that will allow it to be controlled and viewed from anywhere.

8. Compare the spectra to the online internet spectral databases.

9. Provide the capability to log data to remote databases, share with friends and colleagues..

10. Not be just another open source spectrometer..

11. Make it easy to use and intuitive.

12. Make it attractive with an elegant design..

13. Make it useful and just cool to have!



My attempt and results

For the most current information, please visit http://hackaday.io/project/1279 I keep pretty detailed logs of my progress on that site.. Please let me know if you like it! I am a semi-finalist in the hackadayPrize!

Questions and next steps

Finish it and go to space!

Why I'm interested

Because Science!!!

Here's the new 'Semifinalist' video...

There are some pictures below.. just a couple.. But there are a TON more and a LOT more information over at hackaday.io... http://hackaday.io/project/1279

The entire unit.. TFT LCD, Touchscreen display... Neopixel 'working' indicator...Cuvette tray is on the right under the keypad...



Some pictures of the optical assembly...



The filter selector assembly....



The system from the side with covers removed...



System overview..



-------- older stuff... I need to clean up here.. =)

Here are some recent (now a little older) shots of the spectrometer portion...The spectrometer can be used independently from the raman portion, if someone wishes to build just the sepctrometer... It will perform similarly to an ocean optics, etc.. I will be designing adapters for fiber, etc...and it plugs into a PC via USB...





These are some test stands I whipped up for testing my geometry for the spectrometer...



This is the raman portion of the system...From the laser emitter on the right to the objective lens, beam splitter, etc...



A closer look, albeit incomplete view of the raman portion.. this is missing the filter selection assembly...and of course, there's no spectrometer attached either....



This is the interface controller board with the display and touch keypad...and the neopixel indicator ring..



A system overview of how things are connected..



Another more detailed, but probably a little outdated by now...



The casing for the filter selector wheel...



The raspberryPi, and the controller boards in their slots...



A test setup I used for testing the CCD and optics for the spectrometer..



The CCD Detector Array... Toshiba TCD1304 attached to an ST Nucleo F401RE which transmits the data to the raspberryPi via serial.



Inside the box, from the side..



From the top...



And a couple .gifs that show some stuff.. :)
