Which Digital Potentiometer

[BJ43]

What digital potentiometer is being used in VV mods?
How would I wire it to a stepdown after removing the manual (bluebox),

Appreciate any help..

Paging Breaktru......
He is the goto guy for digital pots; his copper mod w/digital pot is one of the best ever.

The digi-POT is a DS-18689-100

Thanks Dalton.
The DS1869-100 for single battery converter. The 04050c requires 100K ohm pot.
For a Two battery converter I use a DS1869-10. 08100w and OKR requires a 200 ohm pot so you have to parallel a resistor across wiper to bring the 10k ohm down to a manageable resistance. Note: the stepping of incrementing and decrementing values will be increased so fine tuning is harder to achieve.

Thanks breaktru, as an aeronautical engineer I can handle basic electronics but normally leave all those black boxes to the experts. As an example if I remove the pot from one of the following regulator, how do I wire the DS1869-10 to it. I use two batteries but mostly 12v VV PT.
