Auto focuser home made

[solarboy]

Hi guys 

Having a go at making a auto focuser 

The ones you buy are so expensive for whats in them so I looked into making one for myself. 

I have bought a motor gear box £40 a circuit board £7 I have bits of ally plate and cables laying around the shed don't know much about electrics so I will leave that to my stepson who has just into astronomy he is an electronic engineer and computer programmer so I will leave that with him to sort out

If he needs any ideas, then have a look at Rob Brown's offering (https://sourceforge.net/projects/arduinoascomfocuserpro2diy/) I've built a few of these & they all work a treat
