Have a look at this: http://en.wikipedia.org/wiki/Light-e..._and_materials (hier in Deutsch: http://de.wikipedia.org/wiki/Leuchtdiode#Flussspannung) Lets say you have 3 green LEDs --> you need (worst case) 10.2V for lighting them up. That's why you need: a) a LED driver b) a voltage that's high enough (i.e. 12V) An easy to use 'LED driver' is an ULN2803A. Rgds aBUGSworstnightmare P.S. How to get 12V out of a device that's supplied by 5V??? That's like trying to get a 55in from your 15.6in laptop display. |

Please leave it as it is. It's the only thing I can fly better than you and I'm pretty sure if you once start to fly helicopters, it only takes a couple of weeks and you dramatically decrease my self-assurance. |

@ paul
what about this www.flyduino.com plate in 0.5mm for the micro quad ? i believe the 1.5mm plate i have here is too heavy but it looks better than the red arrow ( just my opinion ) |

I really forgot about your solution. Thanks for reminding me and filling the black holes in my grey matter! |

just a tip to save some cables, specially servo cables for the flydumini (probably it adopts to other copters too)
if you have the possibility to get a receiver with headmounted pins you could do this. My sender is a T8FG so i can set the output channel mapping as i want them, allowing this or with a bit luck you simply can plug your receiver into the board without any cable. i used female headers with 5mm height |
