  1. Hey guys, I'm leaving my current (dead-end) job doing misc IT-related things and running backups, to hop on and work for my friends CLEC/wISP full time. The salaries are comparable. What kind of future do you think CLECs and Fiber carriers will see? Is it a smart move to drop out of school to accept the position; I would be the only employee and would eventually graduate to a senior technical advisory position in the future.
  2. First and foremost, your motor is not designed to run nitro. You're fuel system is not set up for it. You'd need bigger injectors and upgraded lines. What a lot of performance cars run is methanol injection as opposed to running a leaded performance gas (like the 110 Octane I put in my car ;]) Your best bet is nitrous oxide injection. It works similar to what you're describing. You splice your fuel line and put a T-connector in there. You run the nitrous solenoids into your intake manifold, as well as the new 'fuel line' you've created. That way you don't run 'lean' (too much oxygen, not enough fuel) when you spray the car.
  4. Is a TOS agreement really 'legally binding'? This what I'm using on one of my sites; how will this hold up in the court of law?
  5. Does California throw your car on the dyno and put the detector in your exhaust; or do they just use the diagnostic port. Some cars, you can prevent the obd port from reporting codes with an eprom flash.

  7. Not to back pedal, but after some googling, a optoisolator would rock. Switching a valve on would be a matter of: digitalWrite(ledPin, HIGH); is somewhat helpful, but I'm still unsure as to what else needs to be inline with that optoisolator
  8. as for the hard/soft shift you will probably want to do that by declaring the current/voltage as a variablebecause then you could use 1 button to change the current or voltage. as if you did it with hardware you could use regulators to set voltage but then you would need 4 regulators. or you could use resistors and would need 4 switches to switch all 4 of them hard/med/soft. What about a potentiometer? I would like the software to be 'aware of everything'. I'd like it to 'know' that it's shifting hard, and even maybe able to display it on an lcd.
  9. Also, I wouldn't want there to be a delay when manually shifting either.
  10. You can actually control how hard the clutch pack engages by varying voltage to a line. I'm thinking of using 3-way dip switches for the user to control how hard the shifts are (hard, medium, soft), and looking into a way to output variable voltage to that line; something similar to a relay, but with variable voltage.
  11. It would take to long to piggy-back relay it. Speed is a must. Remeber, this is for a racing application. Redline shifts are perfect, but the rpm should be user-configurable in that mode.
  12. I downloaded the Eagle demo a few days ago, and have yet to install it. I'm looking forward to playing around with it and designing some boards.
  13. Your post is probably the most insightful one i've seen in a very long time. I'm going to try to snag that book, or some other print-material to read at night before I snooze. I just wish life would allow me some spare time to learn this like the back of my hand before producing a product; though in my previous life experiences, nothing is as insightful as diving right in and fiddling around! I found a relay schematic, on the Arduino site (; though I'd have problems sourcing those parts, and I'd still be unsure as to which relay to use. I'd have to agree that an opto-isolator sounds like the way to go, but made me think of a horrible situation: Let's say 1st gear requires voltage on valves 1 and 2 2nd on 1 and 3 3rd on 2 and 3 4th on 3 and 4 What if the opto-isolator blows and valve 1 is engaged, now the car shifts to 4th also enabling valves 3 and 4? Some type of mechanism should cause the device to release all valves if it detects failure. On other feature I forgot to incorporate would be a 'pass through mode', basically another 4 relays that allow the stock connections to the valves to be put back through to the stock AT computer. If you're willing/interested in drafting a schematic and sourcing the parts; I'd be more than willing to compensate you! Let me what you'd like. Thanks much in advance, Joe
  14. How much would you guys want to just design the circuit for me and source the parts? As much as I desire to, I'm having trouble picking this up.
  15. You completely lost me. I've tried to research as much as possible, but again, I'm a lost software guy in this hardware world; and it's really a limiting factor. I wiki'd transistor, but I'm not sure why it would be required off the Arduino. Doesn't the Arduino output 5v from the pins? And what's this of a Darlington transistor array? Sorry to completely drain your time, but google and wiki just having some trouble explaining all of this to me.
