Low altitude hold, auto takeoff, autolanding with kk or Hk v2.1 + Arduino + Sonar

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
  • Reviewed the 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…)

How to Enable real Bridge mode for UPC Cisco EPC-3925 with HTML Injection

A.K.A. Public (and probably static) IP address for residential UPC customers.

I have a huge bandwidth internet connection, so why don’t let my friends download or upload files to my house, it makes feel us closer, it’s funny to share things, it can be actually useful in some cases.

I live in the Netherlands and here are several companies which offer different internet connections, but the common element is that houses are built with fiber channel in mind, differently from Italy, that’s why we have actually 50Mbit in download and 4Mbit in upload. For this reason I want to try to discover, for example, whether the ip address is a static one (still the same in two months) and other funny things.
So the first thing to do is to check if the router distributed by UPC can actually act as a bridge so I can manage myself all incoming connections having a public ip address. Also I have a spare Cisco E2000 with dd-wrt that eventually can assume the public ip while the cisco turns in a simple bridge.

HK V2.1Altitude Hold with arduino and sonar/ping sensor

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”

Raspberry video streaming server for keychain 808 with ffmpeg

Hi there,

I’m writing down some notes about

installing, configuring, testing an 808 Keychain Webcam #3

even if i think it can be appliable to several different models (if they can actually act as webcam).
