Already four years ago, i have constructed an all aluminum equatorial platform for a friend. After  several iterations, still with analogue electronics, it performed perfect tracking.
This is the very first prototype:
 

This is the four year old prototype. Still in use by a friend.

Up till now, there are nine platforms in the field. Testing went on, and all of them are now operated by their owners smartphone. This long testing period turned this construction into a very reliable astronomic Gadget.
And now this turns into a family business. Youngsters take responsibility. A pretty cool situation we think.

Luis, a cutting machine operator takes care about the metal-work.
Pia runs the homepage and step by step, grows into software.
Quirin, an industrial management assistant, takes care of finance, book-keeping, shipping and
all the administrative stuff.

 
Sure, there is finally myself assisting it all and of course taking care that everything
is up to our quality goals.
