The user interface is simpler, just add LCD display and 4 keys. I remember using a induction motor drive that had on a corner of the PCB 16 (SIXTEEN) potentiometers, for configuration of ramp up, ramp down, acceleration, deceleration, max speed etc and these were internal variables, you could "figure out" the real output values (from delta Hz to delta RPM) but it could take a while... (takes in to account slip of the motor and other motor characteristics...). Also changing algorithms is quite easy, changing from a Bessel to Chebyshev -.5db is not so easy peasy... Hi Chris,

In fact, I’ve tailored some of my own more popular posts (about how op amps work) towards teaching people in certain niche areas. Some of the best sites out there (such as Instructables), helps people to learn about their project or the subject they are studying. The mere fact that they are offering free information (that is assumed to be correct) is a very big draw for the masses. Unfortunately, as far as competition goes, there are some major leaders in terms of “how things work” and the smaller players often fall off the map, hence fewer parties trying to explain a topic like when to use analog versus digital circuits.
