Reply to "The new heater for Pearl thread II"

Minuscule progress lately on this - Life keeps getting in the way.    (but then, it took a while to figure out what the heck my-newfangled oscilloscope was telling me.  Maybe if I had paid more attention when my computer techs were showing me stuff....  hmmm?)

A couple more component changes got me to a range of approx. 75 pulses per minute to about 300 per minute.  Not perfect to "idiot-proof" it, but good enough for me.  As a reference, my heater is currently running about 150 pulses per minute and it is warm, but not "hot", so the 300/min will be close to running "too rich" and blowing smoke out the exhaust pipe (yes, the heater has it's own exhaust pipe - Cute little thing, too).

I've also been pouring over Amazon for a little plastic enclosure to put it in (about the size of a pack of cigarettes), a push-button switch to power the whole system on and off (heater and pump) and am currently stumped for a terminal block for the back of the box to attach wires to.  I know what I want, just haven't used the right combo of key words in the search bar to find it - I'll find it yet!

So the next part will be to build the module, mock it up under the dash with some sort of attachment (there is only one place it's gonna fit and be handy) and start making up a wire harness for it.  It would be cool to put the control in a center console like in a modern car, but that ain't gonna happen!  I'm replacing a pulse board that currently sits next to the heater in the car nose with this one that sits under the dash so the wiring harness will be totally different.  Once I decide where to put it I'll mock up a harness, remove it, wrap it in something like shrink wrap for that "professional look" and re-install it.   If all this sounds like a project for over the winter, you're right.  The stuff that's in there now is perfectly fine for now so, like "Mr. Natural", I can keep on driving.
