Revised One Watt audio amplifier with a Mini USB port and a IS31AP4991A amplifier. C1 thru C3 are 1uF ceramic caps, C4 is a 100uF electrolytic. R1 thru R3 are 4.7k-ohm resistors. R4 and R5 are 47k-ohm for a gain of 10 (20 dB) on the amplifier. As in the previous one-watt amplifier, a stereo signal from the 3.5mm jack is combined into a mono signal using a simple resistor network. The USB input is only used as a 5-volt power source.

9x Cree XP PCB for cheap 9-LED flashlights. Although the Cree XP LEDs have a separate, electrically neutral thermal pad, it has been joined with LED- on this board, to help spread heat away from the LEDs. Most LED flashlight drivers use the LED- for current regulation. This board won’t work with those drivers, unless you find another way to isolate the LED- from Batt- in your flashlight. It is meant to be a drop-in replacement in lights which don’t include a driver.
