I wanted to share a new product I developed based on the particle photon. There are more details here: http://perfecttuning.pswebstore.com/en/gauge/54-universal-gauge.html
It’s an automotive 52mm universal gauge with 3x 0-5v inputs available to connect almost any car sensor like wideband, EGT, Oil pressure, oil temperature, coolant temperature and more.
I also included CAN bus communications to retrieve data from aftermarket ecu like Megasquirt, MS3Pro, ECU masters, AEM, and maybe OBD2 too.
The device is always offline but I’m using the wifi to give a web interface to the user for an easy advanced configuration and firmware upgrade.
The enclosure is made of billet anodize aluminum.
