Then I can probably sell few of the extra ones. I’ll fix few things with the setup and document it bit more. Then I can probably sell few of the extra ones.

The fastest is playing the whole buffer in half a second the slowest is very low resolution (all values in long steps) but takes couple of minutes to run throught. There are 256 byte memory in the pic we use, so 256 values, 128 for two pots etc. (continued)… The fastest is playing the whole buffer in half a second the slowest is very low resolution (all values in long steps) but takes couple of minutes to run throught.

However, the resolution decreases, since the pots are read one by one but still quite fast in a loop. The current code supports one pot values to memory and the other one used as the speed. Storing two pot values to memory halfs the available buffer, but additional eeprom or pic with bigger eeprom would solve that. To sum it up, you need to change the pic code a bit to store values from two pots and you split the memory between those two, still this is quite ok if you need short loops. The length of the loop is relative since you can adjust the speed. The fastest is The current circuit supports reading four variable resistors simultaneausly of which we have been using two.

So if there are some kind of variable resistors / sliders / pots inside the joystick, it can. If the analog input is voltages, eg accelerometer, a minor change should be made to the circuit. Switching joystic, the normal ones with just 4 switches of some kind can also be recorded, but that needs different sizes of resistors serially with each switch to identify the 4 or 8 positions or using different pins in digital mode for each switch and changing the PIC code accordingly.
