Its been a long time since i have done some hardware electronics but its something i want to do more of so i decided a Power Distribution Board for the quad was the perfect starter project.
The idea behind this is to develop a Mini PDB specifically designed for the mini 20A ECS that are about right now for 250 or smaller mini quads.
During the wait i decided to CAD it up and see what the result should look like with LittleBee 20a esc’s in place (Having models of these parts will help later when i decide i want to make my own frame).
Finally today the wait was over. came home to find a nicely wrapped envelope form OSH Park in which i found my PDB’s.
They look great. Super impressed with OSH park and i will be using them again. They are double sided, with solder resist and silk screen on both sides. Just 10 working days from design to my doorstep.
And the cost of all this excellent service? . . . . i got 3 copies for £8.40 including shipping. Couldn’t ask for more.
Over the past few days I have been having great fun flying my new Hubsan X4 Quadcopter. This is an amazing gyro stabilised RC quadcopter that is small enough to land in the palm of your hand. It can fly perfectly indoor or out and has enough lift to carry a key chain camera. Only problem is after reading on the forums I realised that the small blades are fragile and can easily become damaged during crashes. Many Quadcopters such as the Parrot AR drone have prop-guards to protect the props from impacts and so I decided to design a set for the Hubsan X4.
These parts were printed on my printrbot and the design files can be found on Thingiverse (http://www.thingiverse.com/thing:61127). The bumper weighs about 4 grams in total and is completely push fit. flight time is slightly reduced as you would expect but this is easily outweighed by the fact that bumps with walls and objects no longer stop the props (causing the quad to fall from the sky).
In the future I may re-design this to be a bit stronger / lighter if I get the time but till then I thought some one might find this useful.
