I have not seen if I can drive both wires at 90% and have it still run. I guess I'm not too worried about it. If all of a sudden it's on full speed all the time, there must be a break in the speed wire, or the controller is fried. Either way it warrants a look to see what's going on. The circuit will be able to drive it at 90%, or 100%, so I can figure it out later, as my current prototype can't do it.


ETA for another prototype... hmm...

I guess it depends on how much more we're going to change the design I know the circuit I need to control the speed of the fan and to read the temp sensor. I also have a circuit that will move the needle on the gauge in the dash. I think we have everything pretty well nailed down, so I could go ahead and order some circuit boards. The alternative is $100 for a development board, and build the entire circuit to make sure it all works.


Oh yea, Andrew, what are your thoughts on the dip switches I used on the boards I sent you? Too hard to switch/too annoying/easy enough?

If you ever find yourself in a fair fight, your tactics suck.
