Hello there !
I'm so glad to have found your video Andras !
Your saber is awesome. You made a wonderfull job !
So much you decided me to build my own.
I've ordered the boards and some leds :
- 110 x green 5mm leds 140° 4000mcd 20mA 3.2/3.4V
- 80 x red 5mm leds 140° 3000mcd 20mA 2.0/2.4V
I plan to make a two string led blade : the main string will be green and the secondary string led will be red and should be trigger as a FoC/blaster hit.
That's the main idea. I need to make some test to see if the secondary string won't produce too much shadow when not lit up. If this is the case it will made a good second blade 
Thank you !
