Need Suggestions for in-race-car PC. Car goes 300+mph. Video?
I've been reading here for a few years and watching the forum grow - I've finally run into a project where I need an in-car PC.
I crew on a race car project where I am responsible for all the electronics in the vehicle. This includes the Engine management system, and the data gathering system(s). This car is built for racing at Bonneville (top / landspeed) and we hope to be the fastest production body car in the world when the car is completed.
It's a custom built, tube chassis car with a 498cid Hemi and two ProMod 91mm turbos capable of 3400+ horsepower. We'll likely only need around 200hp to achieve our goal.
Here's a video of the chassis dyno tuning we performed last week, to get you an idea:
Anyhow, the engine is up and running on Megasquirt-3 which I assembled myself. I also use an IO Extender (add-on kit for megasquirt) to gather data from turbine speed sensors, wheel speed sensors, suspension travel, and a number of fluid temps and pressures.
I've decided that I need an in-car PC to run the TunerStudio software (a simple Java based app) to collect the data from the Megasquirt+IOX. The computer can be a low end, low performer because all it's doing is capturing data over the serial port at 115200bps.
HOWEVER, here are my questions:
(1) I am wondering if I can beef up the in-car PC specs such that I could also record 2, 3 or 4 channels of video. I *can* run independent cameras (GoPro or similar) but the problem is, it's a hassle to start each camera individually while preparing to make a pass in the car. I'd much rather have a centralized recorder with 2-4 channels of video.
(2) Are there decent cameras out there for this? I'd like HD 720p 30fps. Last year I used a couple cheapo Sanyo Xacti CG20 cameras with good luck (see in car footage from our other race car here:
(3) Can anyone here recommend cameras, and in-car PC specs for me? I am running short on time, the event is in August so I have 3 months to put together and test a system for use in the car.
Thanks so much for ANY input you may have,
