Does anyone know any many pulses the (crankshaft mounted) hall sensor creates per revolution?
ah, but you see, i've already got the microcontoller and everything that I'll need to connect it to the output of the crank sensor I think. No need to buy those partsi almost went to rose hulman the phone thing and legos were pretty cool recruitment tools.
Sparkfun is the place to go to get any kinds of good components with a description of what they do. Adafruit, and digikey are good too. It's just a matter of preference. If you are new to programming then you can get an Arduino since they are easy to cobble things together with and have billions of examples laid out for beginners otherwise any chip will do. I suggest getting a serial 2 pin lcd that way you have more pins open for other sensors that you are inevitably going to throw in nor or later. Also it will help when you cannibalize it for another project. its easier to work with and just as simple to code.
Here are two examples that I have copied for other friends drag and show cars that should help you get going. I included the page with comments because they often help add in a little more insight.
nixie tube this one looks great and uses some nice retro tech
pic ax nice and small with a good ability to add more things if needed
For the mounting vacuum forming is a good thing to have and extremely easy thing to make that creates professional products quickly.
If you really want some fun and busy work, design it with an FPGA. It may cost a little more but you will give your self a mighty big hammer that most people never heard of, including your profs.
good luck
I would think 2 pulses? The flag of metal goes by twice per rev.Does anyone know any many pulses the (crankshaft mounted) hall sensor creates per revolution?
the rev counter? You mean for the tachometer in the gauge cluster? sorry.. i'm really not sure what you mean here.dunno what else has been said on here but the signal for the rev counter normally comes from the ignition pulse. It fires once per rev and fires more often if the engine is moving faster.
Why didn't you just get a ready made oil temp sensor? Its already encased and tested to work.My oil temp sensor just arrived. Its tiny! But that's beside the point. I was wondering if anyone had brilliant ideas for what I might encase it in. I don't want to drop the thing in the oil by itself.
