I had built my 3led cap, but i don't like to wear a cap while playing, and it is quite awful-looking
So I wanted to build a 3led clip, and use less material, make it lighter and little. In my cap I used 3 leds (3 volt forward voltage, 30ma forward current) with 9 volt battery, and 3 resistors of 200 ohm (the calculator said I needed this).
For my clip i want to use only one resistor. How should I set up the whole thing? I'm going to use same battery and same leds.
