New Detailed Tutorial and Joining the Tool Foundry

Spectra is an open-ended tool, though we’ve found we got a fair few questions that could be answered with a more detailed getting started video tutorial to get people to a basic level of proficiency as fast and easily as possible.

Check out the video below to see how to go from a Spectra device in a box to getting your first images from a tuned device. You can definitely go much deeper than this with Spectra, but it’s good to start out on the right track. For more in-depth tutorials on particular techniques, there is openeit.github.io.

We are proud to have been accepted into the competitive Tool Foundry accelerator backed by Schmidt Futures and the Gordon and Betty Moore Foundation, which encourages open access tools in science and have been working through their bootcamp all the way up to their recent showcase in New York - you too can apply to it! Here is a video of the final showcase for the accelerator, speaking about the reasons to democratise medical imaging:

Recently we moved countries, and hence paused sales until we figure out how to manage vendors, customs, and sales in the UK after doing this successfully in the US. Stay tuned as we are currently actively making a new batch of Spectra devices which will be available soon, whilst resolving these new arrangements as we go!

Remember, you can join our discord chat channel and newsletter to stay in touch once you get your device!

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.
