shows an FFT implementation using a Cyclone EP2C20 FPGA. It can do 50ksps, 1K points, 12bit precision, 100 µsec/1K complex FFT @ 50Khz clock. May be a Zynq can be used to build a standalone device?
I wonder if the EEG signals can tell if your attention wanders. That may help improve meditation.
Have you looked at/played with the Muse or Muse2 EEG headband?
- lettergram 8y agoThat's exactly what we were doing (without an FPGA), you need at least 8 sensors to properly localize attention though (based on our experiments). Things like the Muse I highly doubt work effectively
- Erlich_Bachman 8y agoPerhaps you should try it instead of "doubting" without any basis. Based on my experience Muse is a great product and it delivers exactly what it says. It's hard to see any other EEG product competing with it any time soon (assuming similar cost usage style. Of course something like what "40 years of zen" are doing will be much more powerful).
- bakul 8y agoDid your experiment show a measurable signal difference between stable vs wandering attention? Mindfulness supposedly helps with executive dysfunction (either due to frontal lobe brain injury or ADHD). It would be an interesting experiment to see if feedback via such a headband can help improve focus.
- shaklee3 8y agoComing from the RF world, those numbers honestly seem trivial for processing. Is it just a money issue or is nobody willing to build something like you did?
- Erlich_Bachman 8y agoMuse Headband did, and they have a finished working retail product which reliably improves meditation practice. I've tried it personally. (No affiliation.)
- shaklee3 8y agoThanks. Love your show.
