Remote controllers

I have gathered a large number of remote controls. Most or to be precise, all of them are to control a motor potentiometer and in most cases a number of relays for switch avrious programs in and out.

Below are two types, one is very simple,a nd the other came in pieces (chip + photo reciever).

A search on eBay or AliExpress will result in many hits.
