Do job One; ++; Do job two.. vs multi-tasking + priority tasks
@ Paulvdh:   What i get from the last comments is that the MCU has headroom to calculate away and stores data into a buffer, then an ISR which is consistently clocked uses...

Do job One; ++; Do job two.. vs multi-tasking + priority tasks
Well, i have repaired a number of synthesizers that you have to tune the envelope lengths with an oscilloscope, so multiple voices all have the same ADSR filter and amplitude...

Name that 1970's capacitor. Great size and specs.
Iv went through and replace all the aluminum electrolytic, the only ones that tested on there way out were 10uf or below. I have seen shorted and burnt tantalum's in the past....

Touch Sensing (Capacitive, Proximity, others?)
With playing around with led switches controlled by Mosfets the charge from my fingers on the gate would keep the leds lit for some time as the charge slowly dissipated. Touching...

Touch Sensing (Capacitive, Proximity, others?)
pnp sources npn sinks. Either way people should play around on a bread board.

Touch Sensing (Capacitive, Proximity, others?)
Play around with simple PNP transistors. Ever touch the base of a transistor and watch it magically sink current through an LED?

Seeking tips on interfacing to 24VDC
Adding a resistor to the logic high input of Q1 divides the voltage down to safer levels at +5.6v.

Seeking tips on interfacing to 24VDC
I just designed a quick logic converter that should suit your needs, depending on your data speed you may have to or can tweak the resistor values. I am not sure of your current...

Seeking tips on interfacing to 24VDC
This rs-232 interface IC may work for you, It can handle +/- 30v input and have an output logic voltage of vcc. Although the DS14C89AN ic shows it  inverting the...
