Well I ain't dead yet... I have mostly kept up on the forum reading. I finally got out of my way to build a doohickey to read and display my exhaust temps. I'm not a fan of the Edge readers that are available so I created my own. As a reminder, I installed 2 K type thermocouples in the up pipes of my exhaust system when I put the transmission in. So here it is - the wire frying, bug smoking, and of course the "why in the &%&$&# isn't my code working???" phase. The blue squares in the left upper section on the proto board are K type thermocouple readers.
Well hard to have a bunch of loose wires in the cab and I really dislike point to point bread-boarding so I tried my hand at creating my own circuit boards. Sure looks nice in purple (the only color offered by the prototyping company).
Adding parts:
All assembled:
Drat!! Made a wiring mistake in the board after all. And then realized I cut the wrong wire while trying to fix double drat!! But hey for a first try...
I upgraded the display when I moved over to the finished board. I got one with a backlight so I can see it at night driving around. It also give me the ability to display up to 8 temperatures. I have the capacity to expand the reader to handle four thermocouples and four temperature sensitive resistors (white connectors on the front of the board).
And here it is all boxed up with a pair of thermocouples plugged in.
It has been really nice being able to see what the exhaust temps are. Especially towing the forklift to help a friend/coworker out when his kids bought some used metal working machinery from work. It was 107* the day I towed the forklift up to his place to drop it off. EGTs were steady around 1150* at 60 mph in 9th gear (direct drive) on the RTO6610. I still need to get a temperature sensor installed the transmission and another in the rear axle. The following morning I picked up the machinery (a bridgeport style mill and 2 manual lathes - around 10k Lbs) and after work drove it all up to his place where we unloaded it (it was 105* that day). Hey A310 - you got a spare 3-53T you want to donate to replace the worn out Continental in my forklift? It just doesn't have the oomph to roll itself onto the gooseneck without an assist from a 6000 Lb come-a-long.
