Hello William, Thank you again for all your incredible support and for providing the previous version for us to test. We will proceed with testing that version shortly. Before we do, we have one more critical discovery to share that we believe…

Hi William, Thank you for your detailed explanation. We purchased the Biosensing Starter Bundle (including the Ganglion) on June 09 of this year. I understand from your note that as long as the sample index increments by 1 consistently, I only ne…

Thank you for your reply. * I was only able to move the switch slightly downward, but I’m not sure what exactly counts as the "DOWN" position (see the attached image for my current result). * Yes, I have connected the two electrodes clippe…
