At the moment most peeps are using the Pi with the Pi camera for lower latency video. It is quite straightforward to setup and send over wifi to a device. However, most people really want to use their Gopro cameras via HDMI out.<br />
<br />
Also the simple task of plugging in a 4G dongle to a Pi is not so simple. The Dongle needs more power than the Pi can deliver, so one has to start including messy powered usb hubs to the mix. Or using a LAN cable from the 4G modem to the Pi.<br />
<br />
The wikipad is going to be cannibalised into an DIY controller using the Arduino Pro Micro to make it as a HID controller. At the moment the is no drone control using Tower/Droidplanner so it is a case of using Tincore to overlay screen areas to allow the controller to press 'launch' 'Auto' 'Land etc etc...<br />
<br />
To achieve my goal of a 4G drone:<br />1) Solve the HDMI to CSI-2 (mipi) adapter riddle.<br />
2) Powered USB hub for the modem, or, LAN cable from modem to Pi? Hmmm....<br />3) Finish the Wikipad - to - Arduino Pro Micro (HID device)<br />
4) Take more break-time and walks. The brain is frying.<br />

So I've been thinking about adding a camera to my raspberry pi 2 board, ad using it to stream video to my android tablet recently. However, one can't just connect directly their fpv camera to this board.<br />
<br />
Everyone knows that the Rpi2 uses a unique 15-pin ribbon cable for its camera-in port.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhcwzHcHnaPehgcU8PsqX6lWwGhS0VlHnX3fTb85oXMdXPY3Lc7H5J3k25MfPpqeLFA8E_KyhQbaDjyGfy3m3WMi8hqUzlhfnqpZbH_BjzT8avNaNMf-7EqgW2tHIwjxwvVKQT19jF-MtY/s1600/raspberry-pi-camera-module.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhcwzHcHnaPehgcU8PsqX6lWwGhS0VlHnX3fTb85oXMdXPY3Lc7H5J3k25MfPpqeLFA8E_KyhQbaDjyGfy3m3WMi8hqUzlhfnqpZbH_BjzT8avNaNMf-7EqgW2tHIwjxwvVKQT19jF-MtY/s320/raspberry-pi-camera-module.jpg" width="320" /></a></div>
This means at the moment if you want to connect a camera quickly, and with no work, you have to buy the pi camera that is ready built with this 15-pin connector in mind.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfTARN8QtBwEx-xFSMbKFS0fYHwTsTMZFI4Pi_kjxHMpH4zBiUVAxM-z5Btjs6KTg4J1A2crhmrHE1nCPOZbWA3oSLyFVhFQ9oA0iB6fT3-zZZ44G_0JcSCoOhcTJwlPwtNPuUe6T1wmU/s1600/Raspberry-Pi-Camera-module+%25281%2529.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="202" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfTARN8QtBwEx-xFSMbKFS0fYHwTsTMZFI4Pi_kjxHMpH4zBiUVAxM-z5Btjs6KTg4J1A2crhmrHE1nCPOZbWA3oSLyFVhFQ9oA0iB6fT3-zZZ44G_0JcSCoOhcTJwlPwtNPuUe6T1wmU/s320/Raspberry-Pi-Camera-module+%25281%2529.jpg" width="320" /></a></div>
<br />
<br />
But what if we could find a way to connect an existing composite/av camera to this port using a simple adapter board module?<br />
<br />

It would allow us then to use out trusty Sony CCD camera with the super-low latency that the Pi2 hardware-GPU camera processing, and allow us to also have CCD camera quality.<br />

Here is the data schematic for the 15-pin CSI connector used on the pi camera:<br />

So, in my pursuit to make my android GCS work with a gamepad, I have experienced some interesting introductory hurdles, but hurdles which all gamepads are experiencing.<br />
<br />

My first and most ideal quest is to use a wikipad controller with my regular android tablet that I have. It was in a junk sale for $5, so I thought it might be a good thing to cut up and experiment with. I feel that it is an ideal shape and form for flying a drone with. It feels immediately comfortable in my adult-size hands.<br />
<br />
I am hoping to enable <a href="http://diydrones.com/profiles/blogs/how-to-run-a-mav-link-heads-up-display-on-android-or-windows-with" target="_blank">QTgstreamerhud</a>.apk with video via 4G:<br />

<br />
What I have found with the wikipad (on a non-wikipad tablet) is that I can't get it to interface. It doesn't work with a <a href="https://www.google.co.uk/search?q=usb+otg&safe=off&rlz=1C1CHFX_enGB509GB509&espv=2&biw=1920&bih=1017&source=lnms&tbm=isch&sa=X&ei=wYVcVb_YOMevsAH19IDYBQ&ved=0CAcQ_AUoAg" target="_blank">usb-otg adapter</a>, it doesn't work if I plug it directly, it doesn't work if I modify it with an <a href="https://www.google.co.uk/search?q=usb+otg&safe=off&rlz=1C1CHFX_enGB509GB509&espv=2&biw=1920&bih=1017&source=lnms&tbm=isch&sa=X&ei=wYVcVb_YOMevsAH19IDYBQ&ved=0CAcQ_AUoAg#safe=off&tbm=isch&q=hc-06" target="_blank">HC-06 or HC-05 bluetooth adapter</a> and connect through this. Why this is, I am unsure.<br />
<br />
My initial plan was to plug it into the tablet, and use a controller mapper app such as <a href="https://www.google.co.uk/search?q=tincore+keymapper&rlz=1C1CHFX_enGB509GB509&oq=tincore&aqs=chrome.0.0j69i57j0l4.1120j0j9&sourceid=chrome&es_sm=122&ie=UTF-8" target="_blank">tincore</a>, to map the controls to those on the flight app such as <a href="https://www.google.co.uk/webhp?sourceid=chrome-instant&rlz=1C1CHFX_enGB509GB509&ion=1&espv=2&ie=UTF-8#safe=off&q=vr+pad+station" target="_blank">VR pad</a>/Andropilot/Droidplanner v1. But as such the <a href="https://www.google.co.uk/webhp?sourceid=chrome-instant&rlz=1C1CHFX_enGB509GB509&ion=1&espv=2&ie=UTF-8#q=wikipad" target="_blank">wikipad</a> is not functioning.<br />
<br />
One google search on android tablets shows up that there is <a href="http://forums.androidcentral.com/google-nexus-4/257448-problems-bluetooth-gamepads.html" target="_blank">an issue with the bluetooth stack on android version 4.2</a>. I am using this version of android on my tablet, so this might affect my ability to use bluetooth as a connection for a gamepad. To test this problem I also have a <a href="http://www.makeuseof.com/tag/how-to-use-your-wiimote-as-a-controller-for-your-android-device/" target="_blank">Nintendo Wiimote</a> in my drawer that I tried to connect to my tablet. And, of course it will not connect. It connects to my windows laptop just fine.<br />
<br />
To help me find some hope in this slowly descending project, I also have a <a href="https://www.google.co.uk/webhp?sourceid=chrome-instant&rlz=1C1CHFX_enGB509GB509&ion=1&espv=2&ie=UTF-8#safe=off&q=ps2+gamepad+android&spell=1" target="_blank">Sony Playstation 2 controller</a> with usb adapter that I use for PC laptop gaming sometimes. I know this controller works as I use it regularly. And sure enough, if I just plug it into my tablet using my USB-otg adapter it immediately works and I can control screen menu items. My optical mouse connects just fine in this way too. Hope..<br />
<br />
So I can rule out bluetooth. It was probably going to increase control latency anyway.<br />
<br />
But, I still like the wikipad form factor. It just feels like my perfect idea of a flight controller.<br />
<br />
My next step, is to try to determine what is the difference between my working Playstation controller and the wikipad. Perhaps the wikipad controller has no HID interface chip on board? Perhaps they put the usb-host chip is inside the wikipad tablet and not the controller? Hmmm.<br />
<br />
What can I do?<br />
<br />
Well, <a href="https://www.sparkfun.com/tutorials/337" target="_blank">I have an Arduino Pro Micro in a box somewhere</a>... Perhaps I can use the ATmega32U4 chip it has to allow me to use it to connect directly over USB.<br />
<br />
I guess it will be a full on gamepad DIY project. I will have to cut all gamepad switches and joystick wires, connect them the Arduino Pro Micro, map them as Digital-in or Analogue-in connections, and hope that this then works. there is no reason why it should not. I will then have a fully open usb controller.<br />

<br />
<br />
Or, I could just use my Playstation 2 controller...But it has so much wire hanging off and no tablet mount. It just doesn't feel as good as a package.<br />
<br />
I guess I could try to buy a wikipad tablet? But I don't want to spend $80+ for an experiment.<br />
<br />
<u>Wikipad options:</u><br />
1) work on the USB interface<br />
2) throw it in the trash, lose $5<br />
3) try the bluetooth mod with a different tablet<br />
<br />
Let's see.<br />

I think not a crazy expensive idea.<br />
<br />
Why?<br />
<br />
Because I think the direction of this will lead to the elimination of the need for camera gimbals to make steady video. I think it will be done in software just like the AR Drone. Also, 5.8ghz gear will not be required - video monitors, transmitters, receivers, also telemetry modules will be redundant.<br />
<br />
This will also make drones lighter and smaller, and able to fly a little bit longer (unless the power consumption of the navio & Rpi affect this).<br />
<br />
Not time to yet to sell your Turnigy 9x, FPV equipment, and gimbals. But It is something to think about in a year or two; if you are not a hobbyist, just a consumer level drone flier.<br />

<span style="font-family: Arial, Helvetica, sans-serif;">If you want a cheap 3D FPV experience, you might consider using a <a href="http://www.ebay.co.uk/sch/i.html?_sacat=0&_from=R40&_sop=15&_nkw=google+cardboard&LH_PrefLoc=2&_pgn=2&_skc=50&rt=nc">google cardboard kit</a>. Combining this kit with your smartphone, and a skyped fpv video to the phone, you would get a 3D flying experience on the cheap. In SBS 3D, of course. There will be lag issues no doubt, but it would be cool for a spectator/co-pilot, or improving disability access to RC flying.</span><br />

I think that the DJI Phantom might have a heads-up on Arducopter as it's video feed is sent via 2.4ghz (wifi frequency).</div>
<div style="background-color: white; border: 0px; color: #666066; font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 16px; line-height: 20.280000686645508px; margin-bottom: 0.5em; min-height: 1em; outline: 0px; padding: 0px; vertical-align: baseline;">

It seems plausible that a specific video-over-wifi app can be made for Google Cardboard & Phantom 2.4ghz video and avoid the lag issues that would exist when using a 5.8ghz vtx & skype workaround to send video from a 'capture device & laptop' to a smartphone.</div>

transmitting video over wifi (2.4ghz signal) to a smartphone app and using the Carboard SDK/Project Tango SDK. It's smoothly compatible when you think about it, compared to attempting to hack most people's 5.8ghz vtx modules.</div>

I mean, are there any Turnigy 9x radio modules that allow you to use 5.8ghz, instead of 2.4ghz?</div>
<div style="background-color: white; border: 0px; color: #666066; font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 16px; line-height: 20.280000686645508px; margin-bottom: 0.5em; min-height: 1em; outline: 0px; padding: 0px; vertical-align: baseline;">
I am aware that there are 2.4ghz VTX & VRX modules available <a href="http://www.aliexpress.com/item/2-4G-600M-Wireless-AV-Transmitter-Module-w-2-4G-Video-AV-Receiver-for-FPV/1707815648.html" rel="nofollow" style="background-color: transparent; border-bottom-style: none; border-left-width: 0px; border-right-width: 0px; border-top-width: 0px; color: #01070a; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;" target="_blank">like this one</a> so it seems that the issue is converting your Turnigy 9x to use 5.8ghz..Or UHF frequency like OpenLRS or EzUHF system.</div>
<div style="background-color: white; border: 0px; color: #666066; font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 16px; line-height: 20.280000686645508px; margin-bottom: 0.5em; min-height: 1em; outline: 0px; padding: 0px; vertical-align: baseline;">
At the moment, In my eyes, this is the future for immersive flight on a consumer level. For most people who have already taken up the hobby of quadcopter building, it's going to be an outlay yet again for you guys to change both your flight controller & fpv transmitters. </div>
<div style="background-color: white; border: 0px; color: #666066; font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 16px; line-height: 20.280000686645508px; margin-bottom: 0.5em; min-height: 1em; outline: 0px; padding: 0px; vertical-align: baseline;">
The other option would be to use a dedicated goggle like the occulus rift connected to a 5.8ghz receiver, but who wants to outlay the money for a dedicated goggle when it's possible to adapt a smartphone that most people already own? It's a cost outlay dilemma it seems.</div>

<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">If you are using MegapirateNG and a Crius AIOP board with the Turnigy 9x, the standard 9x receiver doesn't enable the somewhat important throttle failsafe feature in Arducopter & Mission Planner.</span><br />

<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">It was quite simple:</span><br />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;"><br /></span>
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">I set up MegapirateNG on the Arduino software to enable the default PPM (Changing it from my previous PWM signal), and uploaded it.</span><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">I then plugged the ppm encoder board between the 9x receiver and AIOP, sending the 3 ppm wires (+5v, GND, PPM) to the AIOP board (+5v, GND, A8).</span><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">I powered the 9x receiver from the AIOP board also (powering using the PPM encoder board didn't work for me). I didn't use the MUX wire on the PPM encoder either. It's not necessary.</span><br />
<br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">Then, it was just a case of connecting the ch pins from 9x receiver to PPM encoder as you see fit for your needs.</span><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">I didn't have to modify the PPM encoder at all. It worked as it came, out of the bag.</span><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" /><span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">If anyone wants assistance I'm happy to offer advice. </span></div>

<span style="font-family: Trebuchet MS, sans-serif; font-size: xx-small;">I've been thinking about buying my first RC Plane: A bixler 1.1 with Ardupilot. My finger keeps wavering over the 'buy it' button but it's the conflict of cost with my weekly financial budgeting that keeps me from going through with the purchase. Anyway, my thoughts: I thought as I'm doing this project mostly for myself, and for my own education. I'll be sharing it freely online and making the code available for all. But I can't help thinking, it would be really nice if I could get that Bixler from the efforts I'm putting in. Anyway, whatever. I'm still doing this project no-matter.</span></div>

<br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">I'm finding it quite demanding, but I'm making advances. For someone who has never made an electronic circuit before, I'm not doing too badly </span><img alt="" border="0" class="inlineimg" src="http://static.rcgroups.com/forums/images/smilies/wink.gif" style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px; padding-bottom: 3px; vertical-align: middle;" title="Wink" /><br />
<br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">Anyway, I have learned now, that there are stages/sections to this circuit.</span><br />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">-The Arduino: prints screen text</span><br />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">-LM1881 part: syncs/strips vsync data (somehow. I'm not fully understanding of it yet)</span><br />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">-Camera: displays screen video</span><br />
<br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">I am not sure yet if the LM1881 is supposed to V-sync arduino data, camera picture, or both????? </span><br />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">I learned, that if I just connect the arduino signal + camera video using a </span><a href="http://img.dxcdn.com/productimages/sku_2711_1.jpg" rel="nofollow" style="background-color: white; color: #003bb5; font-family: arial, helvetica, sans-serif; font-size: 15px; text-decoration: none;" target="_blank">composite splitter adapter</a><span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;"> into the monitor, the picture is very very flickery.</span><br />
<br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">So I guess that the LM1881 removes either one or both signal's vsync to allow both to merge. But I still don't get this part, or how to link the LM1881 correctly. </span><br />
<br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">It honestly feels like learning a foreign language sometimes, or how I imagine people with dyslexia feel when trying to understand data. I think, as I usually do, that the project isn't fully understood by my brain properly yet - because it's not been laid-out in a way that my brain can understand it yet. Ugh!</span><br />
<br style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;" />
<span style="background-color: white; font-family: arial, helvetica, sans-serif; font-size: 15px;">Anyway, here's the video of it so far:</span><br />
