So... I've been a little short on updating...there's a lot going on.. But I wan't to say that I'm still looking for some python developers, FPGA, even openSCAD... Below is a preliminary (incomplete) list of where the development is going...

If you'd like to be a developer, email us at dev at ramanpi dot org....and we'll set you up with a developer forum ID, etc.. or you can sign up yourself at dev.ramanPi.org and we'll get you started..

You can find this list, which will be update as often as possible here.. If you think you can contribute to any of these areas let us know!!

3D Printable:

• Spectrometer (just the spectrometer, separate from the raman system)
  • Geometry and "self assembly"
• Beam Splitter Assembly
  • Newer Optics to conform with kit specs ( meaning no eBay )
• Mirror Mount Assembly
  • Newer Optics to conform with kit specs ( meaning no eBay )
• Objective Lens Assembly
  • Newer Optics to conform with kit specs ( meaning no eBay )
• Laser Shutter Assembly
  • Completion of shutter assembly
    • servo needs more solid mount
    • rotator needs to be longer and will divert beam to indicator
• Filter Selector Assembly
  • Newer Optics to conform with kit specs ( meaning no eBay )
• Beam Dump
  • Possibly add sensor to measure laser color and power
• Cuvette Tray Assembly
  • Rework gearing and slide mechanism
  • Include the cuvette peltier

Electronics:

• Spectrometer (just the spectrometer, separate from the raman system)
  • Total circuit redesign using an FPGA
  • Ocean Optics USB4000 compatibility
    • protocol compatibility
    • pin configuration compatibility
  • Possibly integrate FPGA circuit on same board as CCD (or 90deg mount)
  • Client software will accept input from spectrometer outside the system via usb
• controlBoard, interfaceBoard and raspberryPi integrated onto single board using the raspberryPi compute module.
  • This will eliminate the stm32 development boards.. and reduce the PCB manufacturing costs significantly
• Outer case
  • Elimination of the PC computer case and create a specialized box for the ramanPi specifically.

Software:

• Client Software
  • Develop new client software based on a use case study
• raspberryPi backend software
  • Complete server end software that controls the system and retrieves and processes the data transmitted to the clients.

Firmware:

• Spectrometer (imagingBoard)
  • Develop firmware to establish full Ocean Optics USB4000 compatibility.
• controlBoard (will now be controlSection)
  • Shouldn't need to be much change in direction, just completion of portions for PID control of cuvette and imaging peltier, etc..
• interfaceBoard (will now be interfaceSection)
  • Also should not need to be much change in direction, just compltion of menuing system and touch panel interfaces, etc..
