Hey, I’ve been noodling on the idea of adding a little microcontroller to an old car to track oil pressure and RPM. Ever tried blending classic mechanics with some smart tech?
RustFang RustFang
Nice idea. Hook up a sensor to the oil pressure port and a magneto‑style RPM probe, feed both to a tiny microcontroller, and you’ll get a clear readout on a small screen. Just make sure the wiring stays neat—no tangled cables in the radiator pan. If you use a CAN‑bus module you can even log the data to a notebook later. It’ll be a quiet upgrade, but the car will still feel like the old good times, just with a little extra brain.

Sounds solid—I'll grab a small CAN‑bus module and a low‑power screen, then map the wiring so it stays neat under the hood. A log file later for diagnostics? Sure thing.

Sounds good. Just remember the screen is a weak link; keep the power isolated from the engine ground so you don’t fry it when the alternator jumps. If you can add a little watchdog timer, the micro will reboot on its own if it ever goes haywire. Keep the wiring short and tucked away—nothing should catch on a spark plug or a loose bolt. When you pull the log, you’ll see a whole new layer of data to keep the old beast in shape. Happy tinkering.

Got it—I'll isolate the screen power, add a watchdog, and keep all the wires short and secure. Thanks for the heads‑up, will log everything and keep the beast running smooth.

Glad that helped. Keep an eye on heat near the radiator, and when you pull the log just look for any sudden pressure drops—those are usually the first sign of a bad seal. You’ll be keeping this old machine alive long enough to make us both proud. Good luck, champ.

Thanks, will keep an eye on the heat and watch for pressure drops in the logs. I’ll double‑check the wiring and keep the screen isolated. Appreciate the pointers.Thanks, will keep an eye on the heat and watch for pressure drops in the logs. I’ll double‑check the wiring and keep the screen isolated. Appreciate the pointers.

No problem at all. Just keep tightening that harness and you’ll have a smooth ride. Good luck.

Will tighten the harness and keep it tidy. Thanks, and good luck too.

All right, let the gears keep turning. Cheers.
