THP Entry: Digital Gauges For Everything Automotive

DDAQ

Way back in 2007, someone on a VW TDI forum came up with a new boost gauge project. At the time, it was a remarkable feat of engineering, capable of displaying the manifold pressure on a tiny OLED on the dashboard. No project has yet reached this caliber since. [Digital Corpus] is revisiting the project, making it his own, adding a few upgrades, and entering it into the Hackaday Prize.

The D-DAQ, as [Digital] calls his new project is using an absolute pressure sensor, unlike its predecessor. This gives the turbo gauge a much larger range than the original project, and also allows the D-DAQ to measure partial vacuum in non-diesel turbos.

In addition, the D-DAQ has a much wider scope than the original project, and as such will function as much more than a simple boost gauge. [Digital] sees the D-DAQ as being a complete performance monitor and logger, capable of tracking the exhaust gas temperature, battery voltage, and just about anything else with 10 analog pins. Data will be saved to a MicroSD card, and instead of a single display, the D-DAQ will feature three 160×128 OLEDs.

It’s certainly not what you’d expect from a Hackaday Prize entry, but with these features, it’s very possible the D-DAQ could be a successful product
