Hi
I have Celestron NextStar 80 GTL, just bought it second hand. Played with it, decided 8 AA batteries don't last long and would be better to hook it on car battery. Made everything, checked polarisation and still hooked it wrongly
and blew up stepper motor circuit. I had 1 in 2 chances to do it right, but it went wrong, how the hell can I win lotto than?
Now, where in Australia can I buy this circuit?
I know which part blew up, its L293DD, not available in Australia, can order it through x-on website but its printed circuit.
Who can do surcafe mount soldering in Perth, or maybe someone on this forum could do it, I will pay of course. Some companies here in Perth ask $100 just to change this little part with 20 legs
Can anyone help please!
Thanks in advance
bob
