[RadioTelescope] Radiotelescope round 2

[Craig Williams]

Due to various other stuff (job, new house, etc) I kinda dropped this but
Harry is obviously keen to get going again soooo..

Who's interesting in doing some work this weekend?

We still need to fix up the controller box that is attached to the scope,
and replace the power (something I'm not too sure about).

We'd probably also need to provide a mounting solution for the board Harry
is building.

Anyone keen for Saturday evening?

Hello Committee

I'm about to build up an interface board (shield) between an Arduino Mega
and
the two stepper driver modules for the Radiotelescope.

I've got some stepper motor code done on the Arduino which could be used to
serially instruct the stepping (ramp up, constant speed slew, ramp down) in
the final system. Alternatively, it could be used for testing the mount
motion
and then reassigned to another project requiring an Arduino.

The parts cost (including Arduino Mega) is around $150 and I've just asked
Bob
whether that is appropriate expenditure to be reimbursed as a UCC project.
If
UCC has an Arduino Mega then the interface-board-only cost is closer to $70.

I can buy the parts and proceed but if it runs and remains at UCC, would
committee let me know if that is a recoverable cost ?

All the best
