Great idea I have just the board for it too.
Will this work?

Yes. The board I posted is the same, just a smaller version. Nice thing about that uno is you can replace the chip if you mess it up and also use it to program your own chip for your own circuit. 
FWIW:
In addition to the STAB-diseqc 1.2 generator Titanium mentioned:
When I google 'diseqc 1.2 generator' I also find one from emp-centauri. I don't know what it can do, exactly.
For DIY I find the juras-projects website (quite interesting website, by the way!). Maybe his projects are programmable to diseqc 1.2-commands, too.

I was mounting the motor to the bracket and according to the picture in the booklet the latitude adjustment should go to 0 degrees. Mine does not. I'm using the holes for latitudes 10 to 45 degrees. There is a latitude mark for 0 degrees though.
Are you installing at a location at "0" degrees latitude? No? Your location is 42 degrees North... Don't worry, it doesn't apply to you!

Just wondered if I was overlooking something.
Turns out that I'm unable to mount the motor with the provided u-bolts. They won't tighten down on the Rohn 45 leg. Of course, no one around here has shorter length u-bolts in the proper width or style/shape. So now I have either find suitable u-bolts or be creative to get this job done. Any suggestions? I could try to repair the SG9120 also (hrum, I thought I had bought a SG2100 but......). I'm considering using standard straight bolts instead of u-bolts or use some kind of spacers on the provided u-bolts but I suspect it wouldn't secure the motor to the tower properly. I could get some shorter u-bolts but then the width would be different and I'd have to drill new holes and the u-bolts wouldn't be of the original design/shape.
Always used the stand-off bracket when mounting on a Rohn. Here is a photo of a home-built stand-off.
$25 and a trip to HomeDepot should get you back in business!
If you have a J-pole (J-Mount DS-3000 or similar), use two U-bolts to mount it on a single leg of the tower. Not as sturdy, but fast and cheap!

I'm assuming that's a 2 " galvanized pipe. I think 2-1/4" pipe will work also. Maybe smaller than 2" would work also.

I think I had one at one time and I think it came with the SG9120. I don't know if I tossed it or squirreled it away somewhere. Just like hardware, it takes less time to go buy more than to search for it. Besides, I like your idea better. I've seen some fancy stuff done with Sinclair antennas where the mounts extended out from the tower also. I think I saw a triangular mount that would attach to 2 legs of the tower and extend the mast out from the tower - that would be fancy for me.
I got the SG9120 opened up on the bench. Disconnected what was labeled limit switches from the control board but still no movement. It appears that the metal gear wasn't greased all the way around and the non-greased area is rusted. Not sure if the problem is in the motor until I can get it out to test it independent of everything else. Turns out I need to go buy some allen wrenchs. But metric or SAE? Since retiring, I miss the tools I once had access to. Finding parts for this thing will probably be another adventure. By the time I get done with this I could've bought another new HH90 for less money.
Just got the SG9120 working again. Not sure of what fixed it. Took out the motor, applied power and it worked. With the motor out I was able to manually move the gears to the tube - no binding. Put everything back together and it moves east and west again. I don't think the hard limits are working, though, since I can go past 80 degrees in both directions. Hopefully it'll be a reliable motor again. After I get my antenna mount "kit" built I'll get everything back up in the air. Tomorrow's going to be a crummy day and the wind is forecasted to be a bit high so we'll see how it goes.

Yesterday, I got mine up on the tower before the storm showed up. I opted for the aluminum angle for the arms but I'm not sure if it'll be reliable. Some crunching of the aluminum occurred while tightening. I considered hanging on the arms for a test but since it's up 15 feet above ground I decided not to do so.
I mounted the motor but haven't put the dish up. Anyway, it would've been a "good" test to see if anything would shift. The antenna weighs a lot less than me. But then there's wind load.......I wonder if I should have got an HH120 instead since this antenna is actually 99x90 cm.
Now that I got the LNBF replaced I went to program in the Ku sats. But, my HH90 is only rotating +/-35 degrees when using USALS. The manual says it should rotate +/-65 degrees. Not much of a problem for the western part of the arc but there are more viewable sats to the east. I did change from USALS to DisEQc 1.2 and I was able to move the dish +/-65 degrees. I guess I could just use DisEQc instead of USALS but I'd rather use USALS. Is there anything I can do to continue to use USALS or is a motor defect?
Highly unlikely to be a motor issue. USALS is a receiver calculation, not a motor memory position or memory calculation. If the motor mechanically rotates to +/-65 degrees using DiSEqC 1.2, verify the receiver settings. If no software limit is set in the STB, there is a USALS calculation error with the receiver.
What receiver are you using?
What receiver are you using?
Azbox Elite. I get other sats within the +/-35 degree rotation. I disabled the software limits but still no-go beyond +/-35 degrees with USALS.
Yeah, I tried to use enigma but restored back to the last official Azbox firmware. I have an Ultra with the same firmware also. I also have a MicroHD.
It's hooked up to a BUD right now. The wife would be very unhappy if I took it offline.
