A great low buck setup that is often overlooked is multiwii airplane with minimosd for long range osd. The flip32 is cheap and available. I know you didn't like APM for the purpose so maybe the ease of code hackability of multiwii would be more up your alley.

You can run cppm, spectrum serial or even sbus from an openlrs receiver into those boards... And you don't need an inverter for sbus since its inverted on both ends ;-)

There's a lot of big rigs out there with 600 HP, bit no one cared because they are only slightly heavier than this trailer park icon.

We certainly expect nothing less than honesty from you guys and you delivered, I'm sure they will fix their problems but shame on them for glossing over this issue. Seems to be a basic ee problem that they should have not had o. Such a premium priced setup. Inexcusable as no doubt there are many retailers around the globe with this product on their shelves.

Skinnier arms with ribs like I beams would be more efficient as you want the area under the props as open as possible. A more 3d interlock system would be rad too, you could get even more surface area for the glue if the seams were less vertical, I know that creates overhangs, but I would think it could be worth the effort.

Great tips, Ian. Thank you. I'm trying to improve my design skills and will definitely look into your suggestions for a future version. Take care.

Helluva torque converter in that one, lol.

This is the silliest thing I've seen all week. JavaScript isn't as bad as people make it out to be.... But this.... This? Why? Lol
 
NEW PRODUCT – Espruino – Open Source Javascript Microcontroller
http://adafru.it/dvz

Try the JavaScript of things with the Espruino - the world's first open-source JavaScript microcontroller! This little board has an STM32 microcontroller pre-programmed with Espruino all ready to go so you can start playing with Javascript-microcontrollers. Warning: if you only use Assembly and think that even embedded C/C++ is for wimps, this device might explody your head. 

The Espruino is a tiny computer with a JavaScript interpreter, allowing for instant feedback from whatever device you're working with. Simply set up your code with the Espruino and send it to the device without having to wait for the board to 'flash.' 

The Espruino's fast response time has a lot of advantages. It allows for quick and easy debugging and is a great way to test your project before your big reveal. In addition, you can control the Espruino from almost anything - Windows, Mac OS, Linux, RasPi, Android, anything that can talk to a USB Serial port. 

While the main advantage of the Espruino is its instant execution, it can also be used as a traditional board through a Web-based IDE hosted on your computer. The microcontroller also uses less power than Linux Boards (although its of course a lot less powerful as well) so will run longer on battery power, it has loads of IO pins, and it can be used as an IO board for PCs, Macs, or Rasp Pis without having to program it first. Simply take the Espruino out of its packaging and get started! 

There's also more info on the Espruino page including tutorials and code examples. Click here for technical details and a diagram

You probably want to use bigger power wire for that much distance.... There's going to be a not insignificant voltage drop over that distance with that much current going through tiny servo wires.... 16 ga may be massive overkill for the current but the voltage drop will be less... Really, a separate battery and ubec down there would be best.

See this page... At 15 ft 5 volt over 24 ga wire drops almost 2 volts... http://www.bulkwire.com/wireresistance.asp

 2014 Raspberry Pi Bake-Off at Hendrix College #piday #raspberrypi @Raspberry_Pi
http://adafru.it/b112632

2014 Raspberry Pi Bake-Off at Hendrix College:

If you’ve ever wondered what’s so amazing about these little $35 computers, then wonder no more!

The Raspberry Pi Bake-Off is your chance to showcase your own Raspberry Pi projects and creations – for bragging rights, and for the chance to win a Raspberry Pi!

Hendrix College will host the 2014 Raspberry Pi Bake-Off on Friday, March 14 in the Student Life and Technology Center to showcase projects built using the Raspberry Pi learning computer.

…The Raspberry Pi is a credit-card sized computer that plugs into a TV and a keyboard. It costs around $35 and can be used in electronics projects and for many of the things that a desktop PC does, such as spreadsheets, word-processing and games. It also plays high-definition video.

How many watts are you going to be charging with at a time? I figure you're going for the range of something like a big car stereo?

Car alternators are a finite source you know, and pulling extra juice will cause worse mileage. A caravan should have a decent sized alternator, but it might be handy to add another car battery near the chargers as a bit of a buffer.

I'm sure you've done the math but I haven't heard you talk about it so I thought I would ask.

+Ian Ferrell Yes, that would blow the 15A cig fuse. We'll be running a 6AWG wire from the battery, and have a watt meter to track draw/voltage. All the connectors will be fused as well.
