Hi Bob,

I have actually progressed a bit from what I have posted. I am not particularly happy using a gearbox and having to "hack" a telescope that I will be putting it on (Meade 12" Dob). What my idea now is if I can make a wheel with enough spaces it won't need a gearbox etc which means no slippage. This might mean getting a stainless steel disk laser cut (if the price is right). For the sensors I would be extracting them from and old mouse.
I have been also thinking of connecting a Bluetooth to RS-232 converter from Jaycar (XC4130 is the catalog number) to the Dave EK box so I can use it on my new laptop.

Attached is what I am getting a quote on. I will let you all know the price when I get it.

Also I have got a quote on the MAX232CPE RS-232 level converter:

Sub total: $19.80 - MAX232CPE RS-232 level converter x 5 of them
Freight: $7.50
Total: $27.30

if anyone wants one just pm me...
