Hang tight for the wall of text and grab some

My plan is to have a solid EAGLE CAD schematics base for my MultiWii connections. Most commercial shields are very complete but most of the time too complete or lacks one little something.
I also wanted to have a shield specific to each of my projects so I wanted a way to make my own. Started looking into DIY PCB howtos and will link the ones I found the most helpful here:
- Draw the Schematic: http://www.instructables.com/id/Draw...CadSoft-EAGLE/

- Hobbyist DIY PCB design rules: http://www.instructables.com/id/Make...CAD-tools-by-/

- From schematic to PCB: http://www.instructables.com/id/Turn...-PCB/?ALLSTEPS

I would really appreciate any feedback as most of this is information from posts here and there and not much is practical experience yet




1- Arduino Pro Mini 5v 16MHz Pin Out information:

Most of this is from berkely's blog and info glanced here and there. I am a complete noob when it comes to electronics and I am learning along

D2: THROTTLE or PPM SUM signal. For the Y6 and Hexa you need to use two of the RX channels pins (D5 and D6) to connect more motors. So you need an RX that has PPM SUM enabled. This means all RX outputs/inputs are on a single pin. On the shield it is also better to use this connection to feed the RX it's 5V from the same regulated source that powers the pro mini. So a 3 pin connector is needed here on the shield. The...Continue Reading

Hello everyone!!!

Wanted to share my current tricopter (also Y6) design. I am on my third big crash and nothing broke on the frame yet! (30ft+ dead drops...)

It is all made from 6mm Plywood, 12mm wood rods and 6mm diameter nylon threaded rod cut to size.

This is how it looks from the top:





On this picture you can see the two top frame layers. They are screwed together with the nylon rods and nuts and the pressure holds the booms tight, but loose enough to give in case of a crash. The top plate only has holes for the boom holding rods, the bottom plate is cut a different shape to have holes for the lower plate support

You can see how the booms are held on this one:
