[sdiy] Incremental encoder to up / down counter or pots and an ADC

[sleepy_dog at gmx.de]

ah yes, TopUp it was, and probably taiwan too, korea was another company 
and product that we dealt with at that time, i mixed them up ^^
I also don't know if we still have some of that gathering dust somewhere 
so I could check whether they also broke down like the ones I privately 
purchased
