My first quad-copter!

Last year i was getting interested in quad-copters and the potential of those cool flying things! Starting to read about them made me decide to try and build one myself. And i started to search the internet for parts and how-to’s to build them.

Back then the quad-copters weren’t that popular yet and self build quads where the way to go if you where capable of basic soldering and following tutorials that is. I also wanted to make my first build as cheap as possible. That in mind i started to browse Chinese websites for quad-copter parts and electronics. And i managed to gather all the vital parts:

  • X525 frame
  • A2212/13T 1000kv motors (4x)
  • 1 x KK board 5.0 (better get the KK 2.1.5 with LCD Display)
  • 30a speed controllers (4x)
  • 3300mah 3 cell battery
  • IMAX B6 50W 5A Charger/Discharger 1-6 Cells
  • HXT Simple Lipoly Monitor 2S~3S
  • Turnigy 9x transmitter and reciever
  • Propellers (1045 CCW 2x & CW 2x) (Counter clockwise & Clockwise)

 

X525 Frame, motors, BECS and flight controller all bought from dealextreme. As a starter kit this has good value for its money. I would also suggest to buy additional propellers and spare parts if you are new to this hobby. You probably will crash a lot at the beginning and its a hard wait for spares to arrive from china when you crashed the quad.

Turnigy 9x transmitter. This transmitter has lots of possibilities for the low price. It is flashable with another firmware which brings this transmitter to another level. After that it competes with transmitters in a price range at least 3 to 6 times the price you pay for this transmitter.

This is the finished build of my quad copter. As you could see on this picture the KK multicopter 5.0 board is exchanged for a KK Multicopter 2.1.5 board which has a display on board an is directly tweakable from the board itself.  This makes changing PID controller values much easier and is one of the reasons i exchanged my first flight controller board with this new one. Unfortunately i did built this before i was in the blogging mode resulting in no pictures of the build itself.

Altogether the initial price tag on all this together is around 260 euros. After building and tweaking it do i still say its worth it? Definitely yes, the fun you will be having while building an own quad-copter against the out of the box experience with other of the shelve quads is much bigger. One of the advantages of a self made quad is that if something breaks you will know how to repair it because you have build it. And another cool thing is you will feel like macgyver while building it!

Well uhh.. and now!?

Okay, i must admit it has been a while since i have posted some things on this blog, but i had a quite busy business life and in my spare time i did not have the urge to post some blogs about work related stuff. So the blog went kind of down the drain by the lack of time and energy like the titanic hitting the iceberg….

So why do i write this post you ask? Well, i am changing jobs and i suspect that i will be having a bit more time to do stuff like this. And somehow the irresistible urge is arising to do some blog posts. The only thing what will happen is that i will probably start blogging about random stuff that i find interesting and not limiting myself to BI or Arduino topics.

Second thing is that it will be a bit more informal. English is not my first language and writing quality blog posts in English takes a decent amount of extra energy for double checking the writings. I still try to deliver something readable but it may happen that i oversee errors or typos because of not reading it 5 times over and getting it checked by another person before i post something. Feedback is still appreciated and i will do my best to get the posts improved over time as i learn and blogging gets easier for me.

 

Now lets start to talk business…. So i am back and i want to start blogging again. But the big question is: “About what!?” Probably something i am interested in will be suitable. So to name some things i’m busy with is my baby daughter Sophie (7 months old as of writing), quadcopters, brewing beer and home automating aka domotica.

And with this teaser i will end this “first” post of hopefully more to come.

Stay tuned!
