Need a machinist to develop a custom air nozzle for low pressure - low velocity air. The nozzle is large - smallest diameter will be 10mm and the largest approximately 40mm . for prototypes the nozzle can be made out of any material. Paper, wood, metal are all ok. You will make several different shapes and size of nozzle then blow air through the nozzle. The air will carry small bits of paper or sawdust so we can visualize the air flow. You will take photos of the different nozzles recording the pattern of particle distribution and send them to me. I will give you feedback and we will continue trial and error to develop the right size and shape of nozzle.

Hi, I need a design of a monochromator (an instrument that breaks light and passes only light of a specific wavelength) (for more info/standard designs, google for 'monochromator' and select images) The total light wavelength range used is 300nm till 750nm The bandwidth (slit) of light I want to come though is a 50nm range And I want to be able to move that window(slit) of 50nm in steps of 2nm or 3nm So eg. I want to start with the range 300?350nm than I can move it up to 302 till 352, again increase by 2nm so to 304 to 354, etc all the way to 750 Also we need a lot of light. Think of 20 high power leds (white rebel leds, at 500mA each) we can feed in directly (preferred), or via fiber (to discuss). For datasheet on leds look here:   [obscured]  /products/luxeon-rebel/luxeon-rebel-white We are looking for a design that is relatively low cost to make. Control by steppermotor or servo. I'm expecting: -a part list of the components, where I can buy them and their p...

Have 3 key injection molded plastic parts that work together as a (patented) system. Material is 30% glass filled nylon. It is an outdoor application and need to model stress/failure under wind force loads. Have step files for key parts. Looking to have FEA done and improvements suggested based on results. There is a 5/8" fiberglass rod that attaches to the bracket and holds a banner and the wind force is applied to that rod. Videos of the system in action are available to help understand.

This project is new construction. The architectural work is substantially complete and we have CAD. It is a 20 BR/BA group home, one level, with approx 15,000 sq feet. Each room is to have its own controls. There are large common areas. It is to be located in a temperate area with 4 seasons, so heat and cooling is equally a concern, as is the desire for air flow. Apart from that, we are seeking an expert with a general concept that we would select to design and create the documents for the construction of the system. The CAD will be shared in the discussion process. Edited: Proposals should list the type of system(s) you would consider that meet the objective of individual suite temperature control, while also work within the physical parameters of the site and, are a reasonably affordable option. By reasonable, we mean for you to estimate what you think the materials and labor would cost on a scale of 1 to 10 where 1 is $50k and 10 is $150k. The physical restrictions of the home...

I am trying for a second time to find a freelancer that can provide mechanical, electrical, programming, and render for a unique idea. We have an idea for a device that can automatically measure and inject detergent, cell phone alert app. to provide alerts when laundry is done, remote programmable, pre-load liquid and powdered detergent to eliminate measurement and save costs. The system will then automatically inject into a washing machine based on computer program. The device must be able to be controlled by an electronic keypad and easy to use. It must also be able to be controlled remotely. It must be easy for even a child. Deliverable will be: 1. 3D CAD model 2. 3D CAD assembly 3. 2D drawing with general dimensions and specification ready for manufacturing 4. 2D drawing of the assembly with BOM(Bill of Materials) 5. 2D drawing for patent application. 6.

We need the ME of our tech device to be perfected in design for mass-manufacturing. Project budget would be USD$1500. We're a company who places design at the utmost priority. The aspiration of our company is to create technology that truly brings value - whether practically, or emotionally, to the world. In the past 1 year, we have been working to create our first product. It revolves around a technology that regulates voltage output, and is a mobile consumer product. Due to the complexity of our electronics, we have been delayed heavily, and realized recently that its design would have to be revamped. If our product would not be truly valuable to our customers, if it is not perfect, we simply could not offer it. So with our expertise, we have decided to make our device better. Currently, we already have the concept of the new device ready, and will need a truly exceptional ME to assist us with turning it into reality, and then perfecting it for mass-manufacturing Our electrical...

I have 2 adjacent properties totalling about 1.2 acres. In the center there is a natural drainage pattern that goes down to a gulley (ditch). I want to capture some of water when it rains and divert it into a tank and have the excess continue to the creek to continue to drain out wherever it goes (eventually to the ocean). I want a designer to receive my pictures and drawings and design an inexpensive system to harvest water during the raining season and filter it and allow the rest of the water go down.

Description This project will focus on the design of a street light powered by natural resources. The different types of natural resources will be examined and analysed, which includes, solar panels, wind turbine, hydroelectric power, bioenergy and tidal power. This is in order to determine which is the best method of renewable energy to use for the street light as well as due to the geographical location in which the lights will be located which will be the UK. Due to this factor, special attention will be paid to most other resources as there is limited sunshine in most of the UK. Also, the energy capture management will be considered as the energy will have to be stored in order to aid longevity of the lighting and to back up in case there is a problem with the system. The lighting system will also be considered and different existing lightings will be examined and analyzed in order to determine the best and most appropriate system. The structure of the street lights will be design...
