comment Human body and current flow effects
Current in an electrolyte, including the various tissues of the body, is carried by ions rather than bare electrons. Prolonged direct current causes those ions to migrate to/from the electrodes. This causes localized chemical irritation. Most direct applications of electricity for medical uses (TENS, electrosurgery) tend to use AC.

comment Inverted signal in biopotential circuit
In what way is the phase "wrong"? You can't have a causal filter without a phase shift, so the best you can hope for is roughly constant group delay (linear phase) over your pass band.

comment Basic question about voltage
Consider: What does the step function look like from -infinity to 0? What does it look like from 0 to infinity? How can you use this to simplify the integrand?

comment Power 15 meters of LEDS?
It'd be easier to find a strand with all the LEDs in series and drive that with a higher voltage constant current.

comment Where have the 8 bit sound chips gone?
Why not use a modern audio DAC, but feed it a waveform calculated by an emulated AT-3-8912 in a programmable logic device?
