Description:I have a provisional patent and am looking for help to make a prototype. The device should have two digital tuners controlled by a computer, each capable of receiving digital radio signal and digital ID co-broadcasted by radio stations. The computer uses one tuner to scan radio frequencies and sorts available radio signals based on station name, program genre, and music group. This device should be able to find a radio station based on station name rather than by frequency. Some national radio stations such as Public Radio broadcast on multiple frequencies on overlapping terrains. In a moving vehicle, when the signal deteriorates on one frequency, this device should be able to use the second tuner to scan for better signal and achieve seamless transition from one frequency to another without interrupting the program by switching the roles of the two tuners.
Wants:A functional digital radio receiver capable of:
1) tuning in to a radio station based on station name, program genre, or music group co-broadcasted by radio stations;
2) maintain the best reception of a radio station broadcasting on multiple frequencies.
Ask for Sample:If you can put together a functional prototype, I will reimburse you for material costs in addition to the prize, plus 10% share of the patent.

Server 3D Explosion
I need to have a server created to match an existing piece of art, which is an exploded touch screen. Unfortunately the designer is no longer available who created the exploded touch screen. The design should match the look at feel as much as possible and use the same colors and style to show an exploded 1U server.
The Steam Punk Jet Engine F3
Looking for someone to design a cool graphic for my Formula 3 race car. The idea is to render the image onto a 3D image of the vehicle and tweak it until everyone is happy. I'm working on having a 3D image done in CAD as we speak - but would like to start the creative part by soliciting ideas on what kind of images might work on the different parts of the vehicle and how it all ties together. You will see in the attached powerpoint what kind of concept I'm after (Bugatti, VW, etc...), steam punk, jet engines, etc... and you'll also see picture of the actual F3. Again, this will work best once I have a 3D version - so this first round is all about finding cool artwork and figuring out what goes where. I DO want the sheet metal pop-rivet look (from the Bugatti) as the main them for the F# with cut-outs similar to how it was done on the VW to expose the guts. I also think that the large engine cooling shrouds on each side of the vehicle could be jet engine, possibly with small flames shooting out of the vertical breather fins - but that's just one idea. I welcome any and all other ideas.
The purpose of this project is to look into the feasibility of creating a proof of concept electric powered UAV that is autonomous, can carry varied payloads (fixed camera, camera on a gimbal, carry case to transport goods, etc.), has a flight time of 60+ minutes, and most important, radical in design! Must have at least 4 engines. Not looking for a COTS solution or similar. I would like to have the UAS to be modular for various mission capabilities. Mission (Crime Prevention, Fire Management, Emergency Response, Intelligence, Fire Investigation & Damage Assessment, Accident Reconstruction, Search and Rescue, Forensics, Event & VIP Security, Tactical situational awareness & targeting, Perimeter & convoy security, Covert Intelligence, Surveillance and Reconnaissance, Anti-piracy, tactical ship boarding, De-mining, Emergency & disaster response HAZMAT/CBRNE management, etc.) payload(s) and flight characteristics might include: • Surveillance with Gimbal, or Gimbals to allow for 360 degree view o FLIR, HD RGB (or HDMI if possible), NIR, NDVI, LWIR, Lidar • Area Mapping for mitigation, disaster recovery, assessments, inspections, etc. • High Speed with Heavy Lift capability for emergency medical devices/medications. o This is for cargo, with an understanding that a balance will need to be struck to determine maximum flight time. • Tether Mode (for training and long term situational awareness). o The possibility of powering unit and payload feed via tether. • Modular, hot-swappable, payload chamber(s) for Sensor Arrays for various scenarios that might include: o Collision Avoidance o Acoustic Detection and Location (Military, Public Services) o Electrochemical and Infrared Imaging Gas & Liquid Detectors (Environmental Air Sensing, Gas and Liquid Leak Detection, CBRNE) o Field Communications (Military) o Radiation Detection (CBRNE) o Ability to drop payloads such as: • Surface Vehicles (Rover, Boat, etc.) • Infrared Beacons • EPIRB (Emergency Position Indicating Radio Beacon) • Sea Dye Markers • Stable in high wind (65+ km/h) environments o Preferably dust and water resistant • Sealed electronics area and designed for all weather flights o With regards to the Gimbal: • Dependable operation in wet, sandy, or humid environments, extreme temperatures, and in sustained winds of up to 50 km/h • Important: This UAS will NOT be weaponized Must be able to transition from Hover to Forward flight while conserving power: - Fixed Wing Flight; or where the Rotor Wing is locked to operate as a fixed wing - Rotary Wing Flight; as a quad copter with sustained hover capability - Conventional Takeoff & Landing - Short Take Off & Landing - Vertical Take Off & Landing - Reversible In-Flight Transition - Reversible On-Ground Transition. In addition, once the transition to forward flight is engaged, I'd like for the engine(s) to be a silent as possible. No parachute or net for recovery, and no launcher to get it airborne. While I'm not looking for a COTS UAV, I would like for it to use COTS Hardware and Software for the build. Rugged, reliable and capable - dependable in extreme environments • Up to 50-minutes endurance with payload, continuous operation model • High wind tolerance o 40 mph (65 km/h) sustained, o 55 mph (90 km/h) gusts Pre-assembled backpack deployment – airborne in minutes • Folding design protects payload & includes battery for powered standby • Payload, battery, arms, and legs are easily replaced in the field without tools Environmental Temperature Range: • -22F to –122F (-30C to 50C) Navigation LED’s • Red/Green • Red/NIR Modular chassis and modular electronics for easy access/replacement Must weigh less than 55 lbs./24kg With regards to dimensions, I think it will depend on how much of these requirements can be satisfied. Mobility is important so, the dimensions should allow for the UAS to fit into a case or similar. The attached images are for reference only. These show VTOL aircraft capable of transitional forward flight. In addition here is a link to a real example. https://www.youtube.com/watch?v=hUNJTAybCQQ

Modern Design 12v FAN
We are looking for a modern design of a Fan that will be powered by a 12V DC brushless motor. The design must fulfill ALL of the listed requirements to be eligible for the prize (please read all requirements till the end): 1. Design • Modern look & feel • New design, no redesign of existing models • The fan has to use a fan blade, so no Dyson models • Innovative and accessible for a broad audience (see image 1 – mood board) 2. Quality • High quality finish with the use of quality plastic • Components / parts have to be (nearly) seamless 3. Product requirements • Compact - See image 2 for measurements • Light • Rigid • Strong - for bumpy conditions • Easy to use • Quiet • Safe - Loss of fingers is not allowed • Durable 4. Performance • High output • Low usage • Efficient! 5. Technical requirements • Use of a 12V DC brushless motor • Use of 12V wiring • Easy to use locking mechanism • Easy to use positioning solution Product description: This contest will consist of designing a fan that will be powered by a 12V DC brushless motor. Base of the fan: The Fan needs to be mounted on a previously designed base (image 3), so the 12V wiring must lead from the motor housing through the fan to the central point in the base. Fan blade: Designing the fan blade is a crucial part of the contest. The design of the fan needs to facilitate the maximum blade surface possible within the size restrictions of the overall model. Also the fan blade has obviously safety restrictions, so caging of the fan blade is required. This has to be in line with the esthetics of the overall design but shouldn’t interfere with its performance. Positioning and locking: The fan needs to be able to turn/pivot in all directions and be able to be locked in any position. The locking mechanism needs to be low tech, easy to use and in line with the esthetics of the overall design. Also it has to be strong and be able to resist bumpy conditions. Motor: The fan will be powered by a 12V motor (for dimensions see image 4). The fan will be operated by a potentiometer mounted on a PCB (for schedule see image 5) of which the form can be shaped to fit the design (needs to have realistic dimensions for production). The motor and the potentiometer are both external components, so selecting or designing them are not part of the contest. It is important that you have taken into account the dimensions of both parts, the wiring that will be used and the weight the motor has. Speed Control: The speed should be controlled through a turning knob connected to the potentiometer. This knob is an integral part of the design and should be aligned with the overall look and feel of the design. Wiring: Wiring is an essential part of the design and needs to be done efficient and realistically. Furthermore the wiring needs to be accessible for assembly and concealed in the design. Overall requirements: • All solutions need to be manufacturable and preferably seamless integrated where possible; • Parts need to be manufactured using injection moulding with minimal mould complexity; • On conclusion all files should be of a professional quality (including STEP files) so they can be handed over to our Injection Moulding partner; • Non injection components should be minimal and easily available in the market or easily manufacturable; • Modern, minimalistic but high quality look & feel is an absolute must. Documentation: Please provide high quality rendering images (in three colors, matted black/grey, glossy white and glossy red)and preferably 3D PDF(.U3D) files during the contest. STEP + STL files are required on completion. Communication: We will provide comments and give feedback on every entry as soon as possible. Also we will use the rating system available on the dashboard and use the discussion board for general information or comments. We will look at every entry and work as fast as we can, so no need to send unnecessary PM’s. Award: We will award the 1st price ($2,000) to the best overall idea that meets - or only needs minor polish to meet - ALL the requirements.
