The dreaded electronics

Most people dread the "Electronics" section of a bike project. I'm a bit odd in this regard. It's been one of my favorite sections. The reason for this is because I enjoy electronics. For christ sakes, I build an under water ROV for my senior project in college. Yes, I'm a geek. No need for you to point it out. I'm well aware ;-)
 My "work bench" at the start of wiring everything up.
 I got so into making everything that I forgot to take time to eat, let along take pictures. Here's the final result. Small capacitor bank to place of the battery. It's a total of 60mF. Black box is the super secret relay used for super secret things. If I told you what's it for I'd have to kill you. A main fuse and then all the accessory fuses. The other bit of wiring there between the relay and fuses is the 555 timer I used to build a flasher relay to work no matter if the flashers are LED or normal bulb operation. Like I said...geek.
Here's the start of the final enclosure of the electronics above. A piece of straight through 3" exhaust pipe on the right. On the left is a 3" inner diameter exhaust pipe coupler.
 Cut 1" off each end of the coupler and this is the result.
 Now take a piece of 14 gauge sheet metal and use the grinder for over an hour and you'll find there were two 3" flat disks inside that sheet. Neat trick huh?
Those metal disks will then be welded to the 1" sections cut off of the coupler. You see what I did there? I made custom end caps for under $6. More to come later. But for now I must consume pizza and beer!!!
