Hi veganbikes,

I love my "gadgets".

I was just typing "It's really not that complicated" and than had to stop until I could get my laughter under control. Yes I'll admit it's complicated when taken as a whole but when I was putting it together it was small steps so as to not feel overwhelming.

The Shimano Di2, shifting cabling was actually the easiest part, it was pretty much plug and play.

So the hard part was getting the rear brake working right. I'd already had the front working just fine, only took me about 30 minutes with cutting the housing and tuning all three levers. The rear wouldn't release and of course this is 8:00 pm and Ace hardware was already closed. This really sucked because I'd already figure out the fix but the store was closed. All I needed was a "Spring". The torture of it all. I actually ended up adding springs to both front and rear so the levers have the same "feel."

The electrical center, ie white box in the middle, is what I most proud of actually. Compared to the Di2 and multiple brake levers that is the complex part.

Going to geek out for a minute here.
Other than the control head, ie white box with switches, everything else is mounted in the front trunk and frame bag. This has a LiFePo4 battery which charges/runs everything else on the bike. I have hookups to charge either via a solar panel, located on my Bob trailer, or via a single AC connection. Right now it simple switch/relay with an lcd to monitor voltage/current load but I plan on replacing that with an Arduino, microcontroller board in the near future if I can ever make the time. So from my perspective that's when it going to get "Complicated"

Thanks for the replay and glad you enjoyed a look into my insanity.
