increasing pot resistance via bs2
Let's Go!
Posts: 124
i have a 2 axis bowmar joystick that i want to control a motor with. the joystick has 2- 5k pots. i need 2-50k resistance pots for the motor control. these are mil spec precise parts so i want to stay stock with the joystick. is there any way to increase the resistance of my 5k pots, for example multiplying it by a factor of 10, via a bs2 so i can use the stock 5k pots, yet get 0-50k resistance out of the stamp.
it would be very difficult to replace the stock parts with 50k pots.
thanks,

Yes. You'll have to find the digital pot though. I haven't seen a 50k dig. pot, But I haven't been looking for one ether. If You find one, then a simple RCTIME statement will do the trick. Take a look at EXP.#26 in the Stamp Works Manule. SW20-EX26-Servo_Control.BS2.
This will help You in driving the Dig. Pot.

The DS1267-50 is a 50k dual pot version that can easily be controlled with a BS2
