Rasberry Pi Computing.

Would anybody here be (or have children - or grandchildren who are) experts in this field of micro computers?

I want to build something (tilt switch - with 6-8 switched outputs) - scoured the web and cannot find what I want prebuilt.
But I'm pretty sure that with these cheap computers it has to be easy enough. They've introduced a new simple controller board which may be it too.

Basically I want to build an ADAPTIVE LIGHTING module. Using an IMU to determine angle. Maybe MEMS though inertia is an issue. I have used magnetometers and they are set off by anything big and metal (trucks). Single axis and 3-4 programmable switch points per side.

I'm sure it's actually pretty easy - but it's like looking at the ocean and saying - OK I want a fish and I know it's out there somewhere. First you have to learn about boats.

Have you thought about using a cheap used Droid phone? They have the technology built in and use it for bubble levels and camera apps etc.

If I just wanted sensing - there are MUCH cheaper/easier options.
Has to run off 12V - has to switch a good 3Amps PER relay. I'd prefer closer to 5 or 6 amps.

I need to be able to program
"If <rollangle> is GT 5° then switch Relay 1"
"If <rollangle> is GT 10° then switch Relay 2"
"If <rollangle> is GT 15° then switch Relay 3"
etc.

Found a company in China that does masses of sensors - And if I go analogue I'm sure Ken (Decosse) can point me at a voltage based solution.

All you need is a rock and a string, don't overcomplicate it.

Exactly how long have you known me? - Inertial systems really don't work (so I am a bit wary of MEMS) - Nor (from experience) do magnetometers - I think it will require Gyroscopes and Accelerometers.

One-chip gyro w/ analog out. Run AO to 2-bit (literally) A/D

crap won’t work.

Need to find an old school artificial horizon instrument

Looking at this!.

Looks good to me, but what do I know? Would you hook that up to a Pi and then use that to switch lights on/off?

Pretty much - yup. Though, I think following FE_rex suggestion I will forget the Pi. Found a neat, though not so little, box with programmable interface and built in relays for 2Amps. That'll suffice for testing.

I have a similar but rather old tech box used on mining vehicles. And up to a point it worked really well. Into a a bend and at "x" degrees switched on a LED Spot mounted to point at the road where you need light. Worked well on open roads but was based on magnetic field and Big trucks would convince it I was leaning. With the Adaptive headlights I forgot all about the idea. But want to re-investigate. For now just simple R&D - but one hopes to do a bit of distance again once COVID permits. And on something smaller/lighter than the R3.
