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...

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...

Have hand drawn sketches.. Need to put into 2D CAD format for Patent application. I need the attached 3 drawings converted into a CAD drawing with the following guidelines: 1. Drawings formatted for 8.5" x 11" paper. 2. The required margins are, top 1", left side 1", right side 3/4", and bottom 3/8". This refers to the portrait orientation for the sheet and does not change if the drawing is in landscape orientation. Everything, including sheet numbering must be within the margins. 3. The drawings generally must be black and white line drawings. We should avoid shading, it should not be necessary for these views. 4. The safe way to handle sectioning is just to use solid diagonal lines. 5. Reference numbers must be 1/8" high. Use Arial 12pt for reference numbers, Arial 14pt for sheet numbers, and Arial 24pt for Figure numbers. 6. The drawings can be "diagrammatic" meaning not scaled representations of the ob...

I currently have a prototype for a new portable comfort headrest that was designed by one of the engineer. Overall, the design and prototype turned out fine. However, it needs a slight changing in terms of securing and adjusting it. Right now, the prototype carries a strap that holds the device behind any seats, but my concern is about safety, secured device and better idea to adjust the device instead of using straps. I would like to know, if you can finish the design with better secure and help me to built the new prototype as soon as possible. The project is done and design properly. As I mentioned, it just need a slight changing . This project won't take long. I will share the pictures of design and actual prototype as we go along. Also, I am looking for a packaging design for this portable headrest. Please contact me regarding this new product. Good day.

Our project is very simple, the general idea is to produce a product that can rise up a board (a wood piece) to as high as 25" from as low as from 2-3 inches without any electronic components involve but yet it is stable from collapsing. The wood board also can be locked at any height between 2-3" to approximately 25". The materials uses can be just wood or metal/wood, we are open for discussion after you learn all the details. In fact, there are tons of mechanism already exist on the market to work exactly like ours. This project is more like a modification of an existing method to meet our product requirements. If you can do the product design as well, it is a huge plus. So that your right brain and left brain can work together instead of going back and forth with the product designer. If not, no worry, we will hire a product designer here and you just work on the mechanical part is also fine. Please be aware, I am a designer myself, I have a high expectation on ...

Overview We have a product which has been manufactured in the prototype stage. The documentation is not clear. We need to get the documentation back cleaned up for a manufacturable product. We will do this in several stages. Stage 1 (estimated time 8-16 hours) Get a workable cad model in Solidworks of current parts. We have pictures and cad files. IGES The iges files do not translate well. They need to be brought into Solidworks, then saved as Step files, then brought back into Solidworks. This converts the bad geometry. DXF Compare these with IGES models and note any differences. Pictures Compare these with IGES models and note any differences. Stage 2 Stage 2 is dependent on the success of Stage 1. It will involve getting the correct motor and gears into the model. Stage 3 This will involve getting the plastic skins on the machine.

I need a ME to design a mechanism that would go in the arm of a foam bed lounger that would allow a tray type piece to be attached to the arm of a structured foam arm that would have a sturdy clip to hold a plastic or light weight wooden tablet tray that could be adjusted slightly only for the users needs. It's a retail product that we sold for years with a over hanging snake light. I want to eliminate the light and and electric components in the lounger and instead have it be able to hook a removable tablet tray to the left arm

I use a laptop to remotely access a PC. These are both tightly secured so I can not add software. I need something that can intermittently press buttons every 30 seconds (I will open a word doc) so my remote access won't time out during a 6 hour period. The "robot" does not need to be pretty, can be powered by batteries or any other source. My main focus is function.

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...
