I'm looking for a "bogo process" transfer function for a PID loop plant. That is to say something that's not real hardware but just so I can calibrate the software/ensure that the loop is generating sane values prior to connecting it to a real plant and working on tuning. The "bogo loop" would just be say PID core -> PWM output/DAC -> analog filter -> back into uP via ADC -> digital fil

This may not be the appropriate place to post about this. If so, just ignore it, and my apologies. Honda has a dual-mode charging system for US models. When the headlights are on, or any other combination of things that increases the amp draw through the system to a certain point, the computer tells the alernator to put out 14.4V, or thereabouts. But at all other times the alternator...

I am playing around with this old scope in which the power transformer winding for the CRT filaments is arcing internally. In fact years ago I did put in a hi-pot 6.3 VAC transformer and wired it to switched AC internally and it worked for a long time. But now the replacement is arcing. The filament is elevated to about 3,500 volts negative DC. What is the possibility I could find a cheapo ...

George said he needed a problem to think about.... here's a bit of a change from your usual design projects. What's the simplest useful electronic product you can think of? Excluded are small amplifiers & oscillators, those have been done. Heating items such as kettles are excluded as they won't be very useful in this situation. Reaction radios are out due to legal issues. By use

(Not California this time- instead, another Sanctuary City, Seattle.) America's version of Liberals are adamantly against securing the country's borders. It's allegedly insensitive at the least, at worst racist, to prevent people from going where they please, when they please. Meanwhile, the City of Seattle has decided it has a "homeless problem". Their solution includes bui
