Re: Replacing the 7805 on the Raduino so something that does not get so hot

The switching mode regulators are invariably noisy. that's the main reason to avoid them.
MVS Sarma had a suggestion, we can remove the backlight LED out of the regulator and directly feed it with a resistor from 12v. that should significantly bring down the power consumption from the 7805
