Greetings, work on my DIY Telescope GOTO mount continues again.
ET-Base40 Proto board with PIC16C877 cpu, 2-line LCD Display, Stepper motor and driver board. Wired up for first test.
After several attempts re-learning ‘C’ to program the pic, I have the motor on a swing with the rotation on the LCD display.
Unfortunately due to working on it late at night a couple night ago, I managed to fry one driver chip and destroy a motor. Oh well, progress is not without some costs. (about $7, not really a concern)
Here’s a youtube shot of the action: http://www.youtube.com/watch?v=MIUbCfqXFwA
Time to get back into it, more work to be done!
