Hello All,
I am new to this forum but I am happy to have stumbled upon it. Back in college a couple years back I did a project that involved taking as input the boost (pressure) of a super charger or a turbo charger and at a certain pressure, it would activate a pump and some solenoids to inject an alcohol/water mixture into the manifold. This would lower the combustion temperature in the cylinder and would allow high performance motors to run lower octane fuels or add more timing for more power.
Therefore, what I will need at a minimum is:
- Servo output PWM (to control HB-25 motor controller found here:
http://www.parallax.com/Store/Acces...SortField/0/Level/a/ProductID/64/Default.aspx)
- Minimum 3 standard outputs
- Analog to digital input (Need to read 0 - 5 V from a pressure sensor)
In school I used a Dragon12 MC68HCS12 EVB found here: http://www.evbplus.com/dragon12.html. It was a great board, but it is cost prohibitive. I am looking to build a few of these for my dad and some of his friends as test units.
I am not sure how these would be programmed, but I would like to avoid CodeWarrior and anything that would cost too much for a license for the time being.
The two main questions are:
- Are there any specific boards that anyone can think of that can give me what I need?
- Does anyone know of any other motor controllers that can handle 12 VDC and 12 A continuous current other than the $50 Parallax controller mentioned above?
Thanks for the help,
Paul
