Dave [quote][i]Originally posted by willem[/i] Hi there, To all the guys familiar with the transistor controller and the different resistor values you can use on the wiperboard,..here the latest calculation I made which I use on my own controller. obviously the highest value needs to be the first pad and so on. This is the setup for a 12 step wiperboard and therefor 10 resistors, 11 steps to be controlled by the transistor (last step is 0 resistance therefor you only need 10 resistors) and the 12-th step is fullthrottle.

Topic Review willem  posted on 19-9-2008 at 08:26 Dave, The values in the post derive from a calculation sheet I've created 2 years ago. The values from the calculation are based on a linear power response. Not a liniear voltage response. If all the pad values are the same, for instance a 10 pad wiperboard with each resistor 33 ohm, you will get a linear voltage response but certainly not a linear power response. Power is calculated in P = U x I (P = Watt, U = Voltage, I = current). This is the reason why the resistors do not have the same value. To answer your question: The values in the post represent power progressive curve iti20090  posted on 16-9-2008 at 11:40 Hi Willem Are you achieving more linear or exponential response with this combination?
