I will install it at the powerline between my Lipo and my Power distropution, I will be able to measure the current that is coming out of the battery pack and in combination of the voltage over time, I will be able to calculate the mAh that I have used out of the Lipo and can save the Lipos more precisely.<br />

<br />
Sadly the vendor on eBay ripped me off and I had to repair the TX, he reverses the voltage and fried a lot of the circuits. I replaced som voltage regulators and the TX is good to go now.<br />
<br />
I immediately flashed the TX with er9X custom firmware and now I have a perfect TX for my nDROiiD.<br />
I use it with my TR6A V1 which provides a SumPPM sadly there are only 6 channels on the RX but it will do the trick for now. I will try to get a sumppm encoder to use all 8 channels that are available on the TX.<br />

I took nDROiiD with meh and made some Spectacular aerial photos in superwindy conditions.
The copter was very flyable and stable despite of the wind.
I am very satisfied right now.
It were also my first flights with my new tx: Turnigy 9X with er9x mod.

Altough an backflip does not work because of some broken front motors :-/ .<br />
I used my crappy Keychain cam because my GoPro is far to expensive for that kind of maneuver.<br />
<br />
Now I need to improve my throttle handlin, to loose less height:<br />

Maby warthox can help:<br />

<br />
Preparation: uncomment #define InflightAccCalibration<br />
<br />
Step 1 :- Copter on ground, Motors off:<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>- Stick Combo: Throttle + low yaw left + pitch foward + roll right<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>-> Copter Beeps 2 times: Function activated (do it again to deactivate: copter beeps 3 times)<br />
<br />
Step 2 : get airborne and level copter either by trimming TX in hover mode or level it in acro mode.<br />
<br />
Step 3: When copter is leveled (no drift) switch off engines while airborne: copter beeps.<br />
<br />
Step 4: Switch Engines Back on and land: copter beeps long and new Offsets are stored in EEProm<br />
<br />
Step 5: Start again and notice the new new calibration (Important: If you trimmed in level mode: take back all trims on your TX or you will propably crash)<br />
<br />
<br />
Method B: Using the passthrough function<br />
<br />
Preparation: uncomment #define InflightAccCalibration, assign passthrough to one of you aux channels.<br />
<br />
Step 1: get airborne and level copter either by trimming TX in hover mode or level it in acro mode.<br />
<br />
Step 2: activate switch "passthrough"<br />
<br />
Step 3: land and deactivate "passthrough": copter beeps long and new Offsets are stored in EEProm<br />
<br />
Step 4: Start again and notice the new new calibration (Important: If you trimmed in level mode: take back all trims on your TX or you will propably crash)<br />
<br />

I made some short flights in the past days but nopthing serious.<br />
<br />
I had some pretty rough days in december. I was pretty occupied with my Taekwon-Do club and hat not much time for the ncopters.<br />
<br />
But I managed to do some software tweaks:<br />
<br />
I finished and perfected the acc autocalibration and I finally managed to restart the gyro calibration routine at startup if the copter has been moved durin calibration. Pretty handy...<br />
<br />
<br />
Second small projekt was the revision of my fpv gear. I was unhappy with the bold camerahousing and decided to spend some money for the original GoPro skeleton case, this case is lighter and has the opprtunity to connect the video out plugs while the camera is in the case. Abolutely worth the money.<br />
This way the camera is protecteds way better than beforce. Only drawback: The camera has to be mounted upside down but the gopro is capable of rotating the image live so I still can do fpv and all recordings are rotated too. *sigh*<br />

<br />
I programmed a feature that allows to find the perfect hovering zero point for the ACC sensor while inflight.<br />
<br />
At the Shreddiquette community I took part in programming the same procedure after an idea of a fellow programmer and I ported the idea to Multiwii.<br />
<br />
Why:<br />
<br />
<ul>
<li>In reality there is no flat surface, so calibrating the ACC on ground will bring you close to a good value but you still have to find the perfect trim by trial and error.</li>
<li>Every copter is different so a perfectly flat surface does no recognice the inaccuracies in a copter, COG, bent arms, askew pylons etc.</li>
</ul>
<div>
Doing this inflight makes sure you are defining the zero point while in a perfect stable hover</div>
<div>
<br /></div>
<div>
How:</div>
<div>
<br /></div>
<div>
<ol>
<li>Arm the function with a stick combo (see below)</li>
<li>take off and find the point of no drift (in acromode or in hovemode with TX-trimming)</li>
<li>disarm via Aux1 and Aux2 (Aux disarming is a requirement) while flying, fon't worry there is a failsafe that prevents the engine from turning off while yu still have throttle > minthrottle. The offset is measured.</li>
<li>Land and redo the combo to save the measured values. (be sure to undo the TX-trimming you did while flying in hovermode)</li>
<li>Take off again and be happy ;-)</li>
<li>You can do the combo again if you do not want to start the calibration anytime before taking off and do the measurement, to disarm the measurement. If you do not want to save the meausred value just do not do the combo. The values are lost after you cut power. You can always repeat the processover and over again if you are unhapy with the result.</li>
</ol>

Paul from <a href="http://www.flyduino.com/">www.flyduino.com</a> is supplying me with all the stuff I need to get airborne.<br />
He also delivers the newest protoypes for my testing purposes - like the GPS bob or the new Flyduino v2.1.<br />
<br />
He developed the famous Flyduino controller which is powering many many multicopters right now. Also he developed several boards and bobs and offers a lot of RC products for reasonable prices.<br />
The quality of his products is outstanding and the service is great. He delivers fast and reliable and is offering great support. I can recommend this shop and his products.<br />
<br />
My nDROiiD quadrocopter is using the following Flyduino products:<br />
<br />
<br />
<ul>
<li>Flyduino v2.1 flight controller</li>
<li>Flydusense v2 Sensor Board</li>
<li>Flydubution Power distribution board.</li>
<li>Green and orange 8" and 10" props</li>
<li>GPS Bob prototype</li>
<li>Numerous plugs, pins, bolts and a Bosch BMA020 Accelerometer bought at flyduino.com</li>
</ul>
<div>

I am optimizing the software right now. There were some very bad drift issues - so I think about replacing my BMA020 with another accelerometer.<br />
<br />
I have a problem with the Mag, the motor currents distort the mag readings severely.<br />
<br />

Today I got a GPS Bob made by aBUGSworstNightmare from Paul from www.flyduino.com for testing purposes.<br />
After some time of reading and understanding the pins I now have a working GPS onboard.<br />
I am looking forward to try position hold and coming home functions!!!<br />

At the beginning I made the mistake to peek at the copter below the goggles to be sure where it flies. But this is not a good idea: You have to let go and dive into the experience and fly like if you are onboard - only doing so you can be sure to control the copter properly.<div>
<br /></div>
<div>
Tipps for beginners:</div>
<div>
1. learn to fly the copter and be familiar with it's reactions</div>
<div>
2. find plenty of space</div>
<div>
3. perhaps bring someone to keep an eye on the copter while you fly and warn you if you are about to crash into something that is out of the FOV</div>
<div>
4. DO NOT PEEK. Just concentrate onto the screen.</div>
<div>
<br /></div>
<div>
I had some problems with a wobble of death. After agressive maneuvers in stable mode the copter control escalates and I crash. </div>

After a tipp from the rcGroups forum I decreased Level P and the problem seems to be gone.</div>
<div>
I have to make further testing to verify this.</div>

Another troublesome device was the magnetometer. By installing it upside down and turned I had to alter the settings in the software. I had a hard time finding the correct values because I thought that turning the coordinate system is right: After a tipp from Alexinparis I found the correct values and now it is working perfect. The copter holds the heading like a charm.</div>

These Units work wonderfully and are so small, I don't have a problem hiding them beneath the flydusense.<br />
It was a bit tricky to reprogram the magnetometer reading since it was upside down.<br />
I found the perfect parameters for the baro by accident - It is hovering in place perfectly.<br />

I choose the option to call it with my android phone and a couple of seconds later I get a SMS with GPS Date of it's current location.<br />
With this data and the GPS in my phone I can find the copter easily, I did some tests today and the result is promising - I need to get used to the unit though. I will do some hide and seek field testing tomorrow.<br />
<br />
Next Step: Install a better hood for the copter.<br />

<br />
Paul from <a href="http://www.flyduino.com/">www.flyduino.com</a> was so kind to send me a new Flyduino 2.1 for testing and I just soldered the pins onto the board and transferred the firmware, I only used the needed pins now and left the unused pins empty.<br />

<br />
I also had some problems fitting my vibration dampeners to the Flydusense v2 while using the inbuilt dampeners. This nearly loose dampeners were the reason that my boards got separated from the copter after the crash because the threads were to short to get a good grip at the bolts..<br />
<br />
I noticed that the bolts Paul sells in his shop fit exactly into the big holes the Flydusense v2 has.<br />
Now the Flydusense is dampened and secured.<br />

So be shure to head over to <a href="http://www.flyduino.com/">www.flyduino.com</a> to order the boltes and the Flydusense ;-)Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2950694758113781959.post-69214316178965226042011-09-20T14:18:00.000+02:002011-09-20T14:27:28.196+02:00and Disaster strikes ... again!Last weekend I was in Ostfriesland at my father in Law's house, he has a wonderful farm in the middle of nowhere.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://dl.dropbox.com/u/9886652/2011-06-10%20-%20Langerack/3.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="http://dl.dropbox.com/u/9886652/2011-06-10%20-%20Langerack/3.JPG" width="320" /></a></div>
<br />
<br />
After I did somecalibration flights to find better PID parameters I attempted to do a short FPV flight since there was pleeeenty of space around the house. I fired up the gear and climbed upa few meters, because I am not very good doing FPV yet I looked at the copter beneaht the FPV goggles and noticed that it has drifted off quite a bit. I tried to determine in which direction it was heading but it was to late, the wind had taken over command and it was flying further away from me, too late I decided to let it come down, I watched closely at the copter to get a clue where it crashed and ran to my car, unfortuneally the assumed crash site was on the other side of a channel. I raced around the channels but did not find it. Than I headed back to the other side of the channel and searched between the two channels on this small peninsula - nothing.<br />
I crossed the next channel an searched a little swamp and the fields there - still nothing. I thought I hit a channel and this was my second copter gone in two weeks. I sorted out which of my friends gets which of my spare parts and thought about spending more time Windsurfing and with my girlfriend... I gave up again. Because the GoPro was onboard this was a real disaster....)<br />
<br />
<br />
<br />
Then I remembered an important fact: THE FPV GOGGLES!! I watched through the googles: static, DAMN - I raised the antenna from my shoulder and I got a black picture: The TX of the FPV system was still operating!! Yippieh!<br />
So the copter hit ground and not water - but where the frack was it...<br />
<br />
I remembered the fact that 5,8 GHz signal is very sensitive on blocking so I put my hand before the antenna and I determined the copter was north of my position. So I went northwest and did a second bearing to determine the crashsite, I searched for 15 minutes. In the meantime my girlfriend and her parents came to help and brought their dog - but this dog was busy hunting rabbits so he was no help.<br />
<br />
After 10 minutes I circled around and was nearly at the point where I first looked , north of the first channel and THERE SHE WAS - or there was what was left of her. She was hanging in a sheep fence just 1 meter to the bank of the channel and about 800m where I was standing as I started the flight , If there had not been a fence...<br />

x: I was standing here to fly<br />
1. my first searchnode<br />
2. second attempt to find it.<br />
3. I remembered the FPV system here and got a fix<br />
4. I circled around here and spotted the crashsite<br />
red lines: my driving route<br />
<br />
The rear pilons were badly bent, all props were broken, one Motor wos ripped off, the flyduino, and the flydusense were severed from the centerplate and the flyduino was without power (so no buzzer "Find me!" signal), the Lip was lying several feet away from the copter but still connected to the TX of the FPV (how lucky can a man be??) The GoPro was 3 Meters away the protective housing of the Gopro was shredded but the cam was intact and is working.<br />
<br />
I collected all parts and double checked the area (very important: There are cows on the meadows - the can choke on these pieces) I got every single part and was heading home lighthearted. I just saved a lot of money.<br />
<br />
Back home I checked the equipment: Despite the motor everything was still working. I was lucky that she crashed rear first otherwise the gopro would be no more.<br />
The Pins of the flyduino were badly bent but no shortcircuit happened. The motors where still running and the sensors were doing their work. I logged in to giantcod and ordered 6 new motors and got me a cold beer.<br />

I was very astonished that the alu was bent like hell, even the holes but the epoxy was completely unharmed.<br />
<br />
Lessons learned today:<br />
- leanr your lessons man!!! Still no telephone number on it.<br />
- pull the breaks as soon as possible I should have turned of the engines right in the moment I noticed the drift.<br />
- GPS GPS GPS! I need GPS!!<br />
- I definetely need a tracking device<br />
- I need to make shure that the Lipo stays in place and that it can still power the electronics after a bad crash<br />
- better protection of the flyduino tower it got ripped of like - i dunno what.<br />
<br />
<br />
After all it was a lucky day - The copter is almost back in the air - I still need a replace motor and cochones to fly again.<br />
<br />

ps.: Thank god for the FPV system!!!!<br />

Well this is why:<br />
<br />
Last week disaster striked.<br />
I went to the beach to fly my copter an do some nice FPV while filming the giant unifeeder ships, I forgot a screwdriver to mount the FPV equipment.<br />
So I was left with some flights around the picknick blanket.<br />
An hoer later we packed and I wanted to turn one more round, seconds before landing I noticed that the copter went a little bit to far, I was over an open air restaurant so I throttled up, (I did not want to hurt someone).<br />
This was the moment I realized that I had lost orientation. I could not see where the front of the copter was.<br />
I tried some Pitch and roll amneuvers to get it back but it was hopeless.<br />
<br />
Then I did some a very stupid thing, I went into dive and ran towards the copter. It crashed somewhere in the woods in an old castle ruin at the shore - we searched for hours but it was hopeless - old ruins, woods, thorns, high grass and old industrial buildings and not a single clue where in this area it could be.<br />
<br />
The most stupid thing I did was to mute the buzzer seconds before tekeoff because I reprogrammed the voltage code and made a mistake so it buzzed all the time during flight.<br />
<br />
I wanted to cry because I put so much money and work in it - I just added the baro and the mag.<br />
<br />
I thought about giving up this hobby but then I enterd eBay/Flyduino.com/and Hobbyking and about 6 Days later this is the result:<br />

<div class="" style="clear: both; text-align: left;">
Since the first copter was so good I did only minor modifications:</div>
<div class="" style="clear: both; text-align: left;">
- Flydusense V2</div>
<div class="" style="clear: both; text-align: left;">
- mounting hole for buzzer</div>
<div class="" style="clear: both; text-align: left;">
- wiring for LEDs now more clean</div>
<div class="" style="clear: both; text-align: left;">
- lots of improvements regarding wiring and drilling</div>
<div class="" style="clear: both; text-align: left;">
- HK SS18A ESC</div>
<div class="" style="clear: both; text-align: left;">
- coloured 8"/10" props from Flyduino</div>
- no more QuaroPPM because the HK TR6A delivers a Summ PPM signal<br />
The copter is built more accurate because I got more skilled by building the first one I included all the learned lessons from the old nDROiiD.<br />

The most important lessons I learned from the crash:<br />
- always put your Phone number on the copter<br />
- NEVER mute the buzzer<br />
- include a lost model buzzer routine that can be switched on and off<br />
- include GPS tracking<br />
- never fly over terrain that you do not know well<br />
- always keep your eyes on the copter while it crashes<br />
- NEVER GIVE UP (thanks to the guys in the RCGROUPS thread for the support)<br />
<br />
The first stunt and FPV flights are already done and I am quite happy with the results. The new coloured props are a great help and the copter feels a little bit better in the air. Still some PID tuning to do but there is hope...<br />
