Just in case we go with a waterproof quad (I'll move it out to another thread if not), I spent some time over the weekend seeing what I could come up with.
Here is my initial layout for a 450 quad (its actually 445) printable in 14 parts and except for the domed top, glued together.

I think there's a hint in the 3rd video
My powers of observation must be slipping, what did I miss?
-
Blimey! That's set the bar up into the stratosphere.
Very well done Alex.

And congratulations to Pussykrew for winning artist of the year!
Reminds me of the episode of Game of Thrones where Khal Drogo pours molten gold over Viserys head.

James,
Hmm!
Its still there, I just looked.
edit - note to myself, must look for new posts before replying

Hi Nico,
It's a dual gang UK power socket - the type that's normally screwed to the wall.
I used something like http://uk.farnell.com/mk-electric/k2747whi/socket-outlet-2-gang-13a/dp/987207:

Yesterday I started my printer on a 34 hour print. It seemed to be going well so I left it. When I checked on it this morning the print coordinates had jumped back about 15mm and it was happily printing in the new position.
For a while now my front to back axis has had a lumpy feel to it with lubrication having no effect so this morning I took a hard look at it. The timing belt on the left side motor (the one that drives the print head front to back) was lifting at the hard to move point. I dismantled the drive and can see the pulley is malformed.
The timing belt is also damaged.
I need new parts but they are not in the shop, so what do I order?

You can do it http://umforum.ultimaker.com/index.php?/topic/4912-ip-camera-to-keep-a-remote-eye-on-your-ultimaker/ if you have an old smartphone laying around.

My vote is for:
1) A waterproof machine that can carry a GOPRO
However I will probably build #2 if that's the way the vote goes.

IMHO the best fix for the "imperial problem" would be if the 3 countries on this planet which use imperial units officially would change to metric units to meet the other 99% of the World.
What?
We measure in mils which is nothing to do with mm, its 1/1000 of an inch.
There are 12 inches in a foot.
3 feet (not foots) in a yard and 1760 yards in a mile.
There are 22 yards in chain, 10 chains in a furlong and 8 furlongs to the mile.
There are 9 inches in a span and 2 spans to the cubit which is half a yard.
So whats the problem there. :grin:
Woofy,
(who is campaining to have UK speed limits set in furlongs per fortnight).

Ian, my friend.
I know why you are sad - and I can help you.
GET THAT ULTIMAKER OUT OF ITS PROTECTIVE CASE AND PRINT SOMETHING!
(See the new happy corner pic).
I guarantee a smile on your face (:-)

Very nice car,
and Wow! that's some serious power you're dumping into the wheels. I guess traction control is down to your thumb on the stick :smile:

Hi - Good start.
Question 1 already needs one to define cheap - which you do further below.
I think that there needs to also be a question - large and simple.
I also think that it would be cool to ask if we want a project that can be built to start with fairly cheaply (£500) and then by swapping out some of the gear, adding FPV and gopro you and up spending £1000.
So a flexible "platform" that could satisfy many uses - there is a risk it might not satisfy any?.
I also wonder if its possible to rank some of the things that you then ask about - if everyone just ticks them all (who wouldn't) then you will not have a good measure - if they rank then, and everyone ticks everything, but everyone puts waterproof first (PLEASE!) then you know what to narrow down.
Thanks
James
Agree with all of that.
-
Ha ha, "Camel" was definitely a bit "tongue in cheek" :grin:
Waterproof is good. It would be great to land on a lake, dipping a gopro or similar into the water to video the fishes, then take off again.

You sure on that math? 1.2kg of lifting sounds like quite a lot. Actually, that's about the weight of my 2 meter sailplane.
Not 100% sure on anything really.
Its hard to pin down the specs on some of these motors, but generally these 2210 motors seem to be in the 520g to 740g thrust region. Just taking the lower limit gives 2kg of thrust. That sounds about right to me for lifting a quad up to 1.2kg.
Also, the Phantom 2 vision plus uses 2210 motors and has a take off weight of 1.284kg.

Hi Guys,
I've been following this thread with interest and thought I'd chirp up. I've been looking at getting a quadcopter for a while, been drooling over the Phantom 2 vision plus for weeks - but at 1000 pounds its expensive.
I like the idea of building one, but I know so little about these things. I went to hobbyking to see what the cost would likely to be. Wow, the options are mind blowing. I put together a list but would appreciate experienced people to look over it. I think it all matches up but I'm fumbling a bit over it.
HK-T6A-M2 - Hobby King 2.4Ghz 6Ch Tx & Rx V2 (Mode 2.. GBP14.56
155000212-0 - Thunder QQ Super - Multi-Rotor Flight Co.. GBP11.57
9244000085-0 - Multistar 2212 - 920KV Multi-Rotor Motor.. GBP26.09
9045000002-0 - MultiStar 10-4.5 (CW Rotation) Multi-Ro.. GBP1.44
9045000003-0 - MultiStar 10-4.5 (CCW Rotation) Multi-Ro.. GBP1.44
9192000130-0 - Afro Slim 20Amp Multi-rotor Motor Speed .. GBP31.46
Z50003S-30 - ZIPPY Flightmax 5000mAh 3S1P 30C GBP17.48
This comes to GBP104 (EUR130, USD174) and includes the Transmitter as well because I currently have nothing.
The takeoff weight of these parts is 700gm including the battery. I think this should give a total thrust of around 2kg -2.2kg which should make a 1.2kg aircraft reasonably nippy. I would hope for 10-15 min flight times but if we make the battery easy to swap over it should not matter too much. What do you think?
Can I suggest a name for this project?
The "Ultimaker Camel"
(because a camel is a horse designed by a committee)
:cool:

Look at the Business seller information and note the address.
Then read the returns policy!

I use http://www.solveering.com/instep.htm to do the conversion and output a stp file.
It still does not give feature extraction so probably no better than your SW import, but the model can have new features added and subtracted. (I use Geomagic).

Yay!
It's been a long hard road, but I'm pleased you got there.
:-P

Robert - wow, what a valuable resource.
+1 for pinning it.

Does it get better with time?
Heh heh, Nope!
Let’s design a multirotor together.

I spent some time over the weekend working on a waterproof quad. Here is my first draft, I'll move it to another thread if we go with a different design. Its a 450 size quad (actually 445) printed in 14 parts. All parts are glued together except the domed top which is screwed on.
