Photo 7 - This is my high tech solution to holding all the components in place to solder, "scotch tape". photo 7
Photo 8 - When you have a LOT of pieces to solder it takes a LOT of scotch tape. Simple idea, works great. photo 8
Photo 9 - This is the bottom side of the circuit board. The largest pieces are .1 ohm power resistors used to enable the "peak & hold" function of the injector drivers. All the long component leads get clipped flush with the surface of the circuit board. photo 9
Photo 10 - Here most of the IC's are in place. The small components for the injector drivers are in place too. The section on the right is the three channel feedback area. The 8 aluminum shapes above the circuit board are the injector bungs that end up being inserted into the manifold runners (later photos) photo 10
Photo 11 - My original idea was to use the inside surface of the die cast aluminum enclosure as the heat sink for all the T0-220 deivices, (transistors and power supplies). When the enclosure showed up and I opened it up, the ribs made it clear this wouldn't work. A quick scratch of the head showed that the TO-220 devices could be mounted to the floor of the enclosure. Works great!

Photo 12 - Here's the circuit board test fit into the enclosure. At my slow "developmental" pace, it took me about a month of evenings to solder everything into place. photo 12
