Sensing wheel direction.
You could try magnet sensors with a different sensitivity and try weaker magnets. If your magnets are close together the sensor might be affected by the magnetic field of both at...

Rocket staging timer
I would recommend changing the connections on your MOSFET to batt+,igniter,drain,source,batt-. That way you won't be limiting the current to your igniter.

Help: FT232r ceases to function when a relay is activated!
The circuit shown does not show how the motor is turned ON and OFF. Are the uc and ft232 powered by USB or from the same supply used for the motor?

AT90CAN128 availability
I'm having the same availability issue with the AT90CAN32 and AT90CAN64. Can't find them anywhere. We had the same problem with the CAN32 a few months ago.

problem with h-bridge
If OK1B and OK1D are not conducting you will have 24V on the gates of Q3,Q4 and they will be conducting. Check page 5 of the PDF you linked to make sure you respect the truth...

problem with h-bridge
If you apply a constant 5V to ENABLE and REV you have to force 0V on FOW or else both left mosfets will be conducting.

Resistor question (Blinking LED project)
You need to add a resistor in series with the LED to limit the current going through the LED. The resistor value depends on the LED's rated forward voltage and current. Here's a...

Problem in atmega16 SPI interfacing?
I've never used Codevision before but shouldn't you use "unsigned int" instead of "unsigned"? unsigned read_adc(void) { unsigned result; ...
