CLARIFICATION: We DO NOT need renderings ! We need mill work shop drawings in order for the shop to build it. We need 3d views but they will be line drawings with dimensions. We need drawings to give to a woodworker so he can build this bar. We prefer you do the in autocad / sketckup but if you have other software just mention what you would like to use. Drawings must be in enough detail ( dimensions etc.) so the woodworker can order material and build it . We need plans, elevation details, section and 3d views ( 2 minimum) Attached is a rendering of the design for the bar. Also we have attached a bunk bed design we had done - this shows the quality of what we want for the desk. We do not have any files of the rendering of the bar - sorry/ Please just submit two examples of similar restaurant bars you have done - Please note submissions without a fixed fee will not be considered. Thanks

Looking for someone with advanced FEA skills to create a model of a simple impact socket wrench having specific material and dimensions properties (supplied), and then simulate an air impact wrench loading on this socket for the purpose of optimizing the mass of the socket for a specific target load. Modeling the load of an impact wrench is not simple and built in features in AutoCAD are not what we want. This is not the same as a static load, hence the need for someone with the advanced knowledge to model this correctly and simulate needed conditions. Details of hammer mass inside the impact wrench are different for every brand and model, so will need to be approximated. We can supply ballpark figures of rotational load and spikes of impact typical to an average model. Resistance to spinning is based on thread friction between bolt and nut and given CoF with no lubricant. Here we can assume full tightness and allow no rotation, however some torque will still be absorbed or transferr...

We want to create a custom iphone 6 plus case with a funnel for directing the sound of the iphone speaker at the bottom. The case must be airtight around the speaker to most effectively direct the sound. We want to have this 3-d printed asap. We want a service provider who can create drawing in Solidworks or a similar program and also advise on printing materials. We want the service provider to coordinate the printing and get the part shipped to us. The bid should include costs of creating the drawing and coordinating the printing, but the printing and shipping costs do not need to be included in the bid. However, we would like an estimate of printing costs to be included. Previous experience in creating iPhone cases strongly preferred. US location is also a plus for coordination with printing and San Francisco / Bay Area would be great for in person meetings about future projects. Your proposal should include: 1. Examples of similar projects 2. Completion date 3. How man...

Hi there, I'd like someone to build a 12v circuit for me that provides a 60hz sinewave oscillator. We'll later take this sinewave oscillator and use some MOSFET transistors to amplify the signals. We'll then connect a transformer to create a 12v-to-120v inverter capable of 5000 watts. The power source of the inverter will be a 12VDC deep cycle battery rated at 110ah @ 20 hours. The battery will also be connected to an alternator providing 100 amps at 14.3 VDC. If you can build the oscillator, that's all we need for now - but if you think you can build the whole project, then great - please indicate that in your proposal. I look forward to your proposal! Please include the word "inverter" in your proposal so that I know you read this project description. Here's some reference material:   [obscured]  /watch?v=VDi_uFSr3w0   [obscured]  /wp/?p=415 I'd like the inverter to be as close to pure sinewave as possible, but that objective will be limit...

Hello, I'm currently adding to a robot prototype I have, and would like to work with someone who has experience in working with manufactured products. Ideally you are a mechanical/electrical engineer or an industrial designer that would either help with the internal electronics and motors or a designer who will help with materials and 3D designs that are ready for manufacturing. The things I have already worked out are: - The way the robot navigates - Self balancing on ball (see picture) - Dimensions The things I need work on: - A way to interact with the robot - Developing the arms to fit the design - Work with parts (micro processor and such) to help when it comes to manufacturing

Hi, I'm in need of architectural renderings for 8 homes, both exterior and interior images. I've seen examples of various styles of renderings online; B&W, color, and 3D. Attached are a few that I like. I'm wondering how much it would cost for each of these? Can you also let me know how long it will take, as well as what materials you'll need from me in order to complete the job. I'm happy to answer any questions. Thanks for your time.

I'm looking to create my own line of cabinet knobs to sell via my website   [obscured]   Currently, I'm selling a number of other top manufacturers. For my personal line, I'm less interested in completing with the top brands like Amerock, Top Knobs, etc. for standard metal hardware and more interested in selling unique, artsy knobs closer to those sold on places like Etsy or Anthropologie, obviously without copying anything proprietary. I'm especially interested in products that can bring positive attention to the company. I'd be interested in sourcing from disadvantaged communities, using unique and sustainable materials, etc. The more we can create a brand that people talk about, the more it will help with sales of all of our products. I'm looking for a sourcing expert to take on this task and lead the way. This person should have a mix of experience, connections, and creativity.
