Interesting.
I looked at this and while it does have some good features, it is also missing some or does not mention some important things.
It does not look to be very portable and that is extremely important for many users.
Also, the mention of 0.25 v positive offset may be questionable, depending on the method used. If the output voltage is variable, the standard output would cause the offset to vary. Not necessarily bad, just a question. Basically, it appears to be the same as a spooky-2 using a tablet.
