SU-10A Speech recognition board In the late 1970's I worked at a company that made speech recognition products. The devices were 3U (5U?) rack mount. They had either an embedded DEC LSI-11 or Data General...
Dealing with an -Wincompatible-pointer-types warning Couldn't you add a rawbytes array to the union and avoid all the wrangling outside?
Also, the two uint16s only cover half the uint64. That's OK in your app?
uint8_t rawbytes[8];...
One for the analog engineers Someone else will know if €299 is a "good price" but it looks like a lot of fun
Five integrators, two multipliers, relays to set initial conditions. Good to two decimal places....

PB0 works, PB2 doesn't > return PINB & _BV(PB0);
It's not a bool return, it's just a number that results from the 'and' expression.

White noise generation ? In #39, that is not a pink noise source. It's just a low-passed white noise source. The spectrum is not 1/f.
The MiniMoog had a pretty good pink-noise filter;...

Odd Frequency Crystal Needed I think we're misreading that frequency band chart...
SLF is 30Hz to 300Hz
ULF is 300Hz to 3kHz
VLF is 3kHz to 30kHz
So audio tones range from...

In ASCII that becomes "nunkwo" which sure looks like swapped character pairs of "unknown" with the last 'n' dropped/...

Secondly, how do I uninstall built-in boards and libraries which I do not need? You find where the libraries are in your Arduino library folder, and delete them by hand....

PCINT0, PCINT1, and PCINT2 are all within PCINT[7:0] Huh? No. You have 24-ish pins that can generate interrupts. So there are three registers to enable...
