My TIOx setup with 3d printed box.

Post by Megascott » Sat Aug 08, 2020 2:05 am

Hello,

I've assembled Jeans TinyIOx into a case, including 8x 7 segment 4 digit displays. Thought I'd share it here. I am going with an aviation style for my FFR Cobra build, this display will approximate a twin engine display. Two of each sensor, including left and right bank widebands and EGT's.

I didn't use the proto area on the TIOx, rather I mounted the board to a standard 50mmx70mm perfboard. The perfboard and the 5V buck converter is mounted on the lid of the case and wired to connectors on the bottom. The perfboard is wired up as per the same as the Megasquirt 3.0 wiring diagram for the temp and the input for the Pressure and EGT sensors uses the same circuit as the TPS input of the MS3.0 board.

I am using standard GM temp sensors and the offshore SS pressure sensors, as well as 2 AD8495 0-5V thermocouple boards. Easy to scale in TunerStudio.

Printed on a Prusa 3 V2 with PLA. The case only requires supports on the connector cutouts. I glued Boeing style Dzus fastener style screw heads on my case, because the print is flat on that face. No screw holes on the front, drill as required. Attached is the .STL Zip file.

Thank you for all the details. The links don't work for me (it seems to be for an app?) but I can go to the banggood web site and use your description for each item.

If you have pictures of the whole setup in place and overall pictures of the car, I'd be interested in seeing them.

Jean,

In the lay days of C19 I've spent some time cleaning up my project. I spun a pcb for the TinyIOx and two SLC OEM boards, as well as the associated input and output conditioners/drivers.

This board will fit on the back of the 8X Seven segment Display case with the Ampseal connector and tow connectors for the Wideband outputs on the back.

All of this will fit in the dash of the Factory Five Roadster that I am in progress building.
