Quadcopter – Enhanced Lost Model Alarm

Just 24 hours earlier I built my first Lost Model Alarm.  Not being satisfied with good enough, I’ve built an enhanced version.  LoMaE_3Of course, you could just buy one, but where’s the fun in that.  As mentioned in my original posting, I wanted the alarm to have multiple modes for engagement.  First, I wanted to be able to have it triggered while the TX is on using one of the available aux controls.  Second, I wanted it to always come on if the TX looses power (or presumably range).  I’ve managed to figure out how to do this using the Turnigy 9x Pit Trim pot (Aux 2).





DIY Quadcopter Build (MultiWii / NanoWii / Qbrain)

QuadApr14Feb 2014:  If I didn’t have enough hobbies already…  I’ve just gotten myself into the world of quadcopters and flying.  I’ve never flown before.  My RC experience is limited to 4 wheels on the ground.    Navigating with 2 sticks and learning the world of yaw, elevation, pitch and throttle has become my next challenge.  I’ve wanted to learn how to fly for some time, so here we go..

I’m not going to re-create the wheel as credit goes to the folks over at marginallyclever.com for putting together a great build log of the DIY Betamax Quadcopter.  In a nutshell, for less than $300 you can build a very capable quad that should give you plenty of fun and also provide the ability to mount some small and light equipment.  There’s also lots of optional add-ons like GPS that will make the quad smart and more easy to use.  It also uses Arduino-compatible MultiWii which is software that runs on the NanoWii to allow you to control your quad (or other RC machines).
