I have mine put together tonight and it's pretty cool.
I opted to make a permanent cable, and add a larger DC-DC buck adapter with a USB port to power my DIY focuser.
Maybe I'll add a nunchuk adapter at some point when i start guiding... for now this slews nicely with the hand control.
I'll print a 3d box for this later... for now, the zip ties... as I wanted to test.
I have a question about a pulse sound in the drive motors that I'm experiencing while slewing while using this device with Sky Safari 7.
It sounds like the motors are almost trying to stop then continue a couple times a second
It doesn't happen with the hand unit alone.
It does happen whether the hand control is plugged in at the same time as the HomeBrew or not.
At first I thought maybe I had something in my RA gear as it is cyclical but it does it on Dec slew too, and stopped and works as expected upon removing the HomeBrew.

The first 5 seconds of the audio file are without the Homebrew(using the HC), the next 7 are with... I filtered it in Audacity to see peaks and get the mode and it Sounds/Looks like about every 565ms
Is SkySafari maybe polling for position data and interrupting communication?
Maybe Wifi packet transport?
This happens when using wither SkySafari "buttons", or the physical HC buttons to slew.
I'll try it with a different device(a tablet) later in the morning.
Edit: added a noise removed sample of just the pulse.
