Description:
Your task is to draft a mini racing drone from my design specifications.

The drone itself will consist of two pieces of moulded carbon fibre:
- bottom hull
- hood

Key features of the drone:
- two piece construction with interlocking lip
- tube arms (16mm outer diameter, 12mm inner diameter)
- fit 6" diameter propeller (152.4mm)
- 16x19mm standard motor mounting
- fit standard HS1177 camera with adjustable camera angle from 0° - 70° of tilt
- fit standard flight controller circuit board (30.5mm square mounting holes on the bottom)
- 4mm thick at motor mount
- 3-4mm thickness of hull

THE ATTACHED ZIP FILE CONTAINS SKETCHUP FILES WITH DIMENSIONAL DATA, PROTOTYPE IMAGES AND IMAGES TO USE AS A REFERENCE

Deliverables:
- Technical CAD model of drone components
- Inverse CAD model for the moulds for both pieces
- 3D renders

Bonus points for:
- finite element analysis to highlight structural weaknesses and suggest improvements
- include motors, propeller and other electronics in the 3D renders
Wants:
Looking for:
- accuracy
- aggressive style

I would prefer a sketchup model. However I am willing to accept other formats and software if your design is good enough! Especially if you do finite element analysis.
Ask for Sample:
Yes
Software:
  1. Trimble SketchUp (Google)

We do not use sketch-up is it possible to convert to PDF or jpeg so we can view the files.

I'm very experienced in designing in carbon fiber, and for different processes, and can design/build production RTM, prepreg, or vacuum infusion tooling. Happy to take on a project like this but I think you will find the going rate to be about $70-$150 an hour. I would do for a discounted flat fee, but would still need 2 or 3K, not including the tooling design. Having said that, if you can work in sketchup yourself, I'm happy to have a look at what you come up with and give you some design help for no charge.

Decker:

- Lipo will be 4S 1300mAh (32x35x67mm)
- ESCs at a minimum will be Littlebee 20A (24.5x12.5x3mm) but if bigger ones can fit that's great
- Motors will be 2204-2206

What size of LIPO and ESC's do you plan to utilize for this design? Can you also indicate the motor selections you plan for.

mediabox, I've added a new attachment with 2015 versions of the files. Let me know if you still have problems.

I can`t open the sketchup files. I have Sketchup 2015 and seems like i have to install the 2016 version. :facepalm:

UllrichNumber7, the deliverable's don't have to be in Sketchup format. You will however need Sketchup to view the required dimensions etc.

Question, what do you get when you pay peanuts?.
Wed, 20 Apr 2016 21:19:06 +0000
I don't work with sketch up sorry.

My thoughts almost exactly, an almost free design worth $$$$ or ££££. I think when I have a design I'll market it and pocket the cash myself.

And you want all of that for how much???

Unicycle
Hi all, thanks for checking out my contest! I am involved with a company that is looking to receive some entries for a "prototype" electric unicycle. If you aren't familiar let me give you a brief background. Remember the hoverboards last xmas?? The electric unicycle works on essentially the same principle (upside down pendulum theory) to achieve self balancing capability. The current offerings on the market just don't cut it, the plastics are basically thrown together around the requirements of a build, rather than incorporating the necessary components into the design for a smooth finish. I would like the final product to be somewhat futuristic/prototypish looking, maybe a bit sporty. You can get a feeling for whats out there by doing a google search for "electric unicycle". Integral to the design there are 3 requirements. 1.) Obviously the plastic fairing will need to have a cavity for the wheel, but in addition, it will need to subtly include a space for lipo batteries, (doesnt have to be in any particular shape however), and also must include spot for a pcb control board. Both of these items arent excessively large, the PCB is about 4X3 inches and the batteries are about 5X5X1 (but can be reconfigured). 2.) I would also like to incorporate into my design a headlight, and a tail light if possible, but most concerned with head light. Would also like to leave the option open to include small bluetooth speakers, however these would not take very much space at all. 3.) Finally, this design will need to have a retractable handle for balance when getting on/off.

Chocolate Melangeur
I need a stone mill grinder powered by an electric motor. There will be two granite stones weighing circa 10 kg each that will spin on top a granite base, which weighs 15 kg. The base will be at the bottom of a stainless steel pan, which will also contain the 2 stones inside it. The pan will spin by the action of an electric engine/reductor, as its base will be locked on top a metal spinning disc connected to the engine/reductor shaft. The two stones will spin in opposite directions by the action of the spinning base. The stones need to apply a force on the base in order for them to fine ground cocoa bits. In order to that, a system of coils needs to be built so that a force can be applied on each stone. The stones and coil system will have to be easily detachable from the pan, as well as, the pan itself from the disc that holds it, so that chocolate can poured in another recipient.

Industrial Design of a Hand Pulse Detector
We are looking for a industrial design (outlook) of a hand pulse detector. This device will consist of the following. 1) Two metal plates on the device that will come in contact with hand when grip on it. This will form a closed circuit between the plates and thereby detect the electrical pulse from the hand (refer to attached for the existing device). Ideally the area of each contact surface of the metal plate should be more than 2000 square mm. 2) A micro USB port for charging the battery. 3) Power Indicator 4) ON/OFF switch. Internal design of the device is not necessary but must cater enough room to house the below 1) 1500 square mm X 1mm (thickness) PCB 2) 750 square mm X 4mm(thickness) battery. The design shall be in 3D CAD.
