Whats the difference from Blue HEG band and this one?

"signal not quite as reliable on USB power, though mine can be battery powered and used wirelessly"

could you elaborate more on this one please?

would a standard USB battery pack (non lipo) improve reliability?

They don't have an engineer to replace the tech with something more scalable, and the Peanut never really got out of beta so it's pretty fragile. IMO it was half-baked and too costly to produce - with probably a few too fingers in the pot as is usual for medical/medicalish tech. This tech had some great founders but they never had much help, the Peanut was done by Hershel Toomim's grandson who is too busy gaming the cryptocurrency market and doing the silicon valley hotshot thing at the moment to finish the job. Bob at Biocomp (he is Biocomp) is nearing retirement, also, so I'm really the one carrying the torch. I kind of approached him at first saying I was gonna take the work and scale it down cost-wise with some much needed feature improvements whether he liked it or not lol (it was all public domain by the time I was publishing stuff anyway), but he turned out to be pretty cool and I've worked with him a bit since :-) I'm so stubborn about the idea of getting this out nearly at-cost and at the best feature vs cost ratio the tech market can provide that I've gone full in, and am learning EE and a lot of software development from scratch in order to give this out as freely as possible as an ethical statement. You have to do it yourself to do it right in this world, and business and for-profit mentalities very often end up stifling innovation and therefore medical progress as soon as they make any ground - in order to keep that ground. It's like a minefield of little emperors and I have decided to be a shut-in engineer :P

Thanks for the reply I am glad to hear it is better. interesting to see the implementation of Peanut device which is super expensive I think it cost 400 usd just for the device not sure why they can't drop the price.

Hey Leo! Thank you for your support first of all. I am just waiting on the confirming prototypes for V2 to crank out a whole bunch. And no the blue one I think you are talking about is Biocomp's headband. I based my work off of theirs with their help (even cited their patent on my headband, which is public domain) deliberately to drop the price and explore the space myself, while that device was what they were able to produce several years ago and imo is way overpriced but they're pretty nice people. The connections cant be shared without pulling the blue band's connector off and wiring it manually to the ESP32, I am however adding software support for the Peanut as per Biocomp's request. Mine is functionally superior for the most part though obviously not the O.G. and signal not quite as reliable on USB power, though mine can be battery powered and used wirelessly.
