Test Jig, Future Work, and Nearing the Goal

We are so close to both meeting the campaign goal and the end of the campaign! So close! We’d love your support for the final push so we can close in and blow past that goal. For everyone who has backed the campaign, thank you for encouraging us to work on open source biomedical imaging!

Would you like to experiment with biomedical imaging or spectroscopy, or support open source projects happening in this genre in future? Now is the time to show your support! Learn more on the main Spectra campaign page.

Test Jig

Currently we are working on a test jig so that each PCB can be tested while at the manufacturer, so we can ensure functionality of every delivered unit. It’s based on a Raspberry Pi and also has it’s own little PCB for lights, buttons, and mounting the Spectra PCB for testing. Still needs a bit more work to mount it all neatly in a small box, but the testing and programming scripts are all functional. Requirements for the test jig were as follows:

  • remote debugging capabilities
  • unique serial number for each device tested
  • log of each device tested
  • programmatic control over powering the device under test
  • measure board-level power
  • fixture needs to be able to reset itself

Future Development

Also in the works are some updates to the dashboard so that it works reliably on OSX, Windows, and Ubuntu - thanks Dan!

As for future work, we are planning a deep learning tomography effort based on some papers at ICLR suggested by Tom Bishop, who has attended the Spectra hacknights. We hope to be able to obtain better spatial resolution, with a small amount of data!

Almost There!

Thanks again if you’ve already supported the Spectra campaign. If you haven’t yet, now is a great time to do so - we’re nearing the end of the campaign and would love to push through the goal and make these fascinating techniques more accessible. Thank you for your support!

Product Choices


Spectra Starter Kit

This kit has everything you need to get started experimenting with biomedical imaging, including a small tank phantom, 32-channel flex electrode array, USB cable, and fully assembled, flashed, and tested Spectra board that works with easy-to-install open source host software.


Spectra Deluxe Kit

The whole deal, ready to go. You get everything in the Spectra Starter Kit, plus a custom portable enclosure, an electrode expansion adapter, and a 32-channel, gold-plated electrode cable for performing EIT scans on almost anything, anywhere!


Expansion Kit

This kit includes an electrode expansion adapter and a 32-channel, gold-plated electrode cable (the same as those included in the Spectra Deluxe Kit). The expansion adapter lets you patch out to a standard 0.1" header so you can connect it anyway you want to anything you want. The 32-electrode cable allows you to stick the device on a variety of conductive objects of different sizes as each electrode is independent, gold-plated, and protected by an insulated injection molded cover. The expansion kit gives you the flexibility you need for nearly any experiment.
