Just wondering if the following is doable. I'm now running my flat

field light box off of a 3 -6VDC, 700ma wal-wart type power supply.

What I would like to do is run it through the +6V out jack on the

AP900 control box. Is this doable, or does a possibility of damaging

the unit exist? Any idea of amperage capacity of this jack?

The 6 volt output jack is limited in the amount of current that you can draw.

How much does your lamp draw?

Roland,



There are four of the Radio Shack mini lamps. I believe they draw

around 100 - 150ma each. The 700ma power supply works fine, but if

the 6V jack would work, it sure would be handy...

Give it a try. The regulator has a built-in overcurrent cutoff, so the worst

that can happen is that you lose power, but the device is fully protected.

Roland,



Thanks for the info. I gave it a try last night (quick test only) and

it appears to work. I'll give it some more testing this week out at

our observing site.

I did the same thing for a light box. I bought some 6v lamps from radio shack and 5 sockets. It works great!

I built it out of an empty 2gal paint bucket.(plastic) I mounted the lamps in a piece of luan plywood and wired them out the back. I recessed the plywood about 3" off the back of the bucket. Then I cut two pieces of diffuser material so they would be about 6" away from the bulbs. Then I cut a hole in the lid just a bit bigger then the diameter of my scope. (AP140) I then stretched a layer of white fabric over the bucket and snapped the lid on. This holds the fabric in place. I just aim my scope at zenith and place the "light bucket" on the end of the OTA. I also lined the inside with aluminum foil to prevent it from becoming a lamp. Although, before I did, it was handy for tear downs in the dark.
