Custom Board

[siracalypse]

I'm trying to find a way to make/find a basic control board that will send 3V to an RF transmitter connected to a switch.
I would also like it to timestamp each time the trigger is pulled (and store that data so I can plug it into my pc).

How would I go about doing this?

This is all I need it to do, essentially. I do not need it have ramping or any features other than timestamping a lever switch activation. It doesn't need to be a paintball board at all.

Not exactly what you’re looking for but might spur an idea. I logged pressures and each “trigger pull” at the solenoid connection with time stamps using a simple data acquisition system. Let me know if you want more details.

If you had access to an Arduino board, you could connect a couple of lines from your trigger to GPIO. Then use HID code and run that via USB to your pc to a log file. It's similar to an app I wrote for Android. It will run 15 seconds and logs how many times you tap the screen then it tells you the bps. But this being a hardware solution, this would be way cooler. (Now I'm thinking of doing this now )

If you can explain to me exactly what you want to do I might be able to help you.
A few questions that come to mind:
What exactly are you hoping to achieve?
Do you want help to build a tiny Board (I could help you)?
Do you want to add a microprocessor? I am assuming you want to because you want to send timestamps
Do you need USB?
What will you do for power?

I can't do much with the information you gave.
If all you wanted was to actuate a RF transmitter with 3V power from an existing board all you would need to do is figure out how the Microswitch is triggered, add a transistor and a optocoupler in parallel to the microswitches out put. Have a 3V regulator which you connect to the boards 5V rail or the battery. The gate voltage of the transistor should be tie to ground via a resistor on the output of the optocoupler. and the Source of the optocoupler should be connected to 3V line. The source of the Transistor should also be connected to the 3V line the drain should be connected to the RF transmitters power input. Remember to connect the RF transmitter to ground. Now every time the trigger is pulled it also acuates the optocoupler which will then trigger a transistor which will turn on the RF-Transmitter power. You can use a capacitor on the transistor to keep the signal alive for a bit longer. An alternative to the microswitch is to put the optocoupler with a resistor in parallel with the solenoid that way you will have more controlled pulses to the RF transmitter.

I assumed A LOT, so with out knowing what you want to do it is difficult to help you man...
