Production Update

Production is going well and all parts are in from boxes, packing slips, flexPCBs, electrode cables and more. We are just waiting for the main PCB fab to complete, then will move on to kitting and mailing out.

In the meantime, here are some stories from our travels!

Laser Cutting at Noisebridge

Noisebridge hackerspace in San Francisco has been a stable and wonderful makerspace for the last 10 years. One item it has is a great laser cutter. I moved to this new design for the PCB enclosures as it’s much simpler to do in a larger quantity.

flexPCBs and Phantoms

We have a fantastic set of fully tested 32 electrode, gold plated cables in, as well as all made to order phantoms from our plastics extruders. The flexPCB electrode array that fits in the phantoms came in too and in the picture above you can see what was left after we de-panelized them.


We were also asked to speak and workshop at DEFCON’s ever expanding Biohacking Village about biomedical imaging and paths forward for open healthcare innovation. The biohacking village had an interesting range of talks on hacking existing medical devices, and got members from the FDA, medical device companies and security hackers to have some conversations together which seems like a great step forward.

Stay tuned for the next production update coming soon, and join our discord chat channel 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.
