HackEEG CrowdSupply campaign coming soon

HackEEG has been in short-run production for a limited set of customers for over 4 years, and is being used successfully in major research institutions all over the world. Now we’re excited to announce that we’re going to sell a batch of HackEEG on CrowdSupply soon. Click the image above (or here) to sign up to be notified when the campaign goes live!


HackEEG connectors

I got new versions of two flavors of connector boards back from the manufacturer recently. One flavor (DIN EEG connectors) was partially assembled, and I built it this weekend. The other flavor (screw terminals) was fully assembled. Here’s some pictures.

Connector-8 DIN 42-802 board with electrodes

The Connector-8 allows you to connect human electrodes to the HackEEG via DIN 42-802 connectors.

Connector-12 is for connecting the HackEEG permanently to wires via screw terminals, this can be useful when integrating into other devices or for connecting test equipment.

They look great. The only issue is that the Connector-8 board with the DIN 42-802 electrode connectors is somewhat hard to build. When soldering the the electrode connectors onto the board it’s difficult to get them to be 100% vertical. So I’m thinking about using some other connectors that have a different orientation, but have a large flat side that makes it easy to get them to all be exactly straight.

Here’s four of the unassembled Connector-8 boards:

These connector boards are open source hardware and are made for the HackEEG, a high-performance biosignals acquisition shield for Arduino Due and Mega2560.


Starcat blog

Hi, this is the Starcat blog. I’ll be posting things related to Starcat projects and other interesting related items. The first project I’ll be posting on is HackEEG, our ADS1299 Arduino Due And Mega2560 shield that is a high-speed, high-resolution analog-digital converter and amplifier, designed for biosignals acquisition. It can be used as an EEG if it is used as a battery-powered system. I’ll say more in upcoming posts. Welcome!
