i've made a 2MSps Logic Analyzer using Arduino Mega. Please check it out at AMLA - Arduino MEGA Logic Analyzer and give your C&C. Cheers.
Not bad for a few days work.

this is a distress call in busy time while considering several brand of USB LA to buy. since the signal to be tested is only 20KHz, so i tried with arduino. so i guess i dont have to spend extra $100++ for dedicated device. i'll see the effectiveness while in real situation testing.
