Here you are my latest crash during a heavy snowing.
I had some damages: one motor with bended shaft, an arm of the Q450 was slightly broken and rubber band philosophy always wins. In fact thanks to the rubber bands both the cameras simply detatched from the platform falling on theur own weight, avoiding sustaining the entire platform weight, as at the opposite, the poor motor #4 did.

Arduino Sonar hc-sr04 code
I use the hc-sr04 for keeping my quadcopter at same altitude triggered by an added channel but also for automatic take-off and automatic landigs (still in progress).
So i used this piece of code to initialize it and do some test.
Is is good enough within 3,4 meters, not more.
This is the arduino hc-sr04 code: Continue reading “Arduino hc-sr04 code: example arduino sketch”
Ho deciso di tradurre questo articolo in italiano poiché ho notato che molti dei lettori sono per l’ appunto, italiani.
Ho ricevuto la mia nuova i2c sensors breakout board…
Questa è quello che nella configurazione del software MultiWii viene chiamato GY_80 o
Non sembra essere indicato il marchio del produttore o il modello / seriale. Quello che si conosce sono i nomi dei singoli componenti utilizzati per questa scheda Continue reading “[ITA] Multiwii MWC 10DOF cinese (aka GY-80) e Arduino: connessioni e test iniziali”
This post is under constant update until i find a complete solution
I’m publishing it even if it is not complete because i’ve found some working (into compiler)
code and probably there are a lot of people out there in my same situation and we can help each other. So… UPDATES 2012-12-06
I made all connections
code and renamed vars so you can actually understand while you read I compiled and uploaded the sketch (the first one has errors)
I added an
LED for signaling the status changes I’m working on thelemetry (battery voltage)
I switched to a new
ping library I released new
code I updated this
discussion about arduino + sonar/ping + kk/hk board It works with any configuration (tricopter, Y4, Y6, xcopter, quadcopter, hexcopter, octocopter, 12 rotors and so…)

Yes i have to admit it: last time i tried to take off just with goggles, it crashed. 🙁
It was frustrating also for the poor #4 motor that lost all the small balls of the shaft bearing, consequently grinded within magnet and coils: corps everywhere. didn’t cry, yet. Continue reading “HK V2.1Altitude Hold with arduino and sonar/ping sensor”
If you just downloaded the KKMulticopter Flash Tool on Mac OsX, like me and once launched you get:
Uncaught exception in main method:
java.lang.UnsatisfiedLinkError: /Library/Java/Extensions/ librxtxSerial.jnilib: no suitable image found. Did find: /Library/Java/Extensions/ librxtxSerial.jnilib: no matching architecture in universal wrapper

Well, i just received my i2c sensors breakout board…
Here it is what the Multiwii software configuration calls GY_80 or
There is no brand, no model, no serial.
We know something just about single main components/chip: Continue reading “Multiwii MWC, Chinese 10DOF (codename GY-80) and Arduino Nano V.3: hooking and testing”
