Thanks SUPRKR. This gives me additional confidence that the solution we’re developing will work. I’m making steady progress on getting everything ready for the big test this weekend. While it’s been slow going, I should have the final test PCB ready to plug in on Saturday. Owing to the small size and very close placement of the four pins on each of the three Fakra receptacles that have to be soldered to the PCB, it’s been very challenging to make these by hand. And yes, you’re right. The four pins and connecting wires in the cables carry +12v, ground, LVDs +, and LVDS -.
My car is now at the shop for threading of the cable for the front camera from the grille under the nose cone to the area above the crash bar behind the nose cone. As noted in my earlier post, I could not find a way to do this, and concluded that the front bumper would have to be removed. The shop, however, thought it might be possible without front bumper removal. Let’s hope. I’ve asked them to photograph and take note of the procedures so I can post them here. Obviously, anyone who does this mod and mounts the front camera under the nose cone will need to know how this is done.
Your post also suggested another mod that might be possible once we got this front/rear camera system to work: creation of a dash cam that would continuously record the front and rear images for play back on the touch screen or downloading. With HD cameras front and rear this would make for a dash cam vastly superior to any commercial products. Of course, the technical challenges here would be substantial but if it’s possible I think we have the knowledge and know how among our members to get it done.
But first things first. I hope to report on the results of the camera switch test his weekend with both video and still photos.
