Coolant temp gauges.
I made about 15 by hand.
Handed off prototype to an EE, and an ME.
Spent about $2500 in man hours getting the boards designed, plastics rendered and prototyped etc, more refined software written.
I was going to have to go in another couple thousand just to get all the circuit boards made (hundreads) at a profitable rate.
Then tooling plastic molds, and running that was going to be a killer as well. What would have made it profitable was to have it the "brain board" interchangeable with a bunch of different applications "display" boards and do a whole breadth (not just nissans) of applications.
All in all, the company was NOT positioned for it last year, and still is not now. In two years we might be.
Surface rust already? Faster than I had thought. So-Cal was just under 2 years.
Stainless hardware is too brittle, the surface "rust" is a reaction with the black oxidize. There is another coating I am considering, but the RPSport Subframe Support Braces have not hit the sales volume to justify stripping and processing the hardware like that.
If you have any major issues with your hardware (you really shouldn't), please write me asap and I will fix it.
