now i understand how to do a regular rheobus but how and whatwould i need to do a pushbutton rheobus like macromans in his pc-60 case????
Sorry, I totally misread the question. I thought you were referring to the xBus with the push-on push-off pots. Hence my trivial answer, sorry.
sorry, I must go to a friend's now, I don't have the time fot the shematics now but this is woh to build one use bit-tech's fan regulator's shematics, the one with the lm317 but instead of the variable resistor, use a digital potentiometer with an up down interface and take care that the value of the potentiometer is approx the same as the potentiometer's one
same here..i'd rather have the fans on when i want them ect ect.. but i also like the conventiality of just pressing the fan controller in instead of flicking a switch....
well c from what i read it looks like its a rheobus which means (to my limited electronics knowlege) that it pushes from on and off but all turns to control the voltage....i dunno maybe im wrong but thats what i thought thats y im interested in these things.........
I think the original question referred to a digital pot, wherer there's a push button each to turn it up and down. You'll just have to source a digitral pot and build it, but you'll be using a voltage regulator design since a digital pot can't dissipate the power required for a straight rheobus design. Ditto with the push-on-push-off pots, you won't get one rated 5W so you'll need to build the regulator design.
Of course you could always bodge one by simply sticking a push switch behind the rheostat, then create an enclosure for the rheostats that will allow them to move back and forth to activate the switches. Just call me bodger! (Bloomin' works good though)
I found a simple digi-pot controller at EDN Access - Digital pot control , a momentary DPDT rocker switch alters the setting. Problem now is finding the pot over here.
