I have problem with the hardware (http://www.lirc.org/receivers.html). 1. what is the w for the 4K7 (resistor)? 1/4w, 1/2w, or 1w? 2. what is the v for the 4.7uF capacitor? 50V, 100V?

If my back of a fag packet calculations are right the maximum dissipated power through the resitor is about 100mW, so 1/4w is fine. Given the cap is just to smooth the 5V output of the regulator, then 50v is more than enough. Ian ____________________________________________________________ Do You Yahoo!?
