I was getting tired of my disorganized electronics in the dome, so I made this little holder that mounts everything cleanly and is easily removed.
It’s just a piece of acrylic bent into a U-shape with an extra L-shaped shelf glued in the middle.
The various electronic boards are velcro’d into place for easy removal and the whole thing attaches to one of the dome ring supports.
Top: Syren10 Speed Controller (Dome Periscope), 12V/24V DC/DC Power Converter
Middle: Power Distribution Board
Bottom: 12 Channel RF Receiver
I secure the wires that run up to the dome to make sure I don’t accidentally pull everything off when the dome is removed
Please ignore the 16 gauge wire as well, I was running short of something lighter but didn’t want to make a special trip to the store.

I’m using simple 12V SPDT automotive relays in my droid to control switching of power between normal operation and the charging system.
Typically automotive relays are 30A/40A, but I felt I needed something a little bit more substantial. I found these 60/80A relays at SkyCraft for less than $5, which is very reasonable. I’d tried to find something local but came up blank.
The only catch is the terminals are 3/8″, instead of the more normal 1/4″, luckily I found some at Pep Boys for a couple of bucks. I’m hoping to work on getting my electronics re-installed this week and i’ll swap these into my setup at the same time.
Back when I was thinking about stepping up my Pittman dome motor to 24V, and not wanting to have the extra complication of tying two batteries together to make 24V, I’d ordered some small Voltage Converters from ebay to experiment with.
I’m probably not going to install it for the new Dome motor as it’s working fine at 12V, but I do have a 24V supply in the dome for the rear logic lights. This will allow me to have a single 12V battery and save some weight. There is a loss of energy and battery life due to the conversion, but it’s supposed to be in the 90% range.
Update 5/1/08: Andy tipped me off that these board can also be found here.
