I know a famous 317 Red laser driver out there just wonder if any other circuit that can drive the diode with one cell (3.7v)?
Hi M,
yes there's Lazeerer's Xdrive's that are awesome drivers. You just have to know the input current requirements for the diode you are using. The 700 mW Osram and the 500mW Mitsu will use 1 or 2 3.7V cells.

you can use 1x 2r2 ohm and 1x cap 10uF. yeah! good luck
