DWV

Power supplies are rated at full draw, so a 12v 1amp power supply will deliver 12v with a 1 amp draw, if you are drawing less than 1 amp, the voltage will be higher.

Most electronic devices are tolerant of minor voltage swings (+/- 10%)

Looks good!

You're right, if we are not using the full length, why not just cut it off even with the edge of the platform?

New guy here, I am looking to build one of these for my 8" dob, I pretty much have everything I will need here, but have a couple questions.

Could you extend the segments (following the same curve) to get longer times between resets, or would that put the platform/telescope on too much of an angle?

And would changing the angles on the top plate to bring it to the tip of the segment, change how it would work? (so you don't have that point sticking out)
