So I am interested in possible applications of phase change material. A few kickstarters around that are using them in small amounts to keep drinks cold or hot for longer. I am looking for an engineer/product designer to put together for me a brief on using phase change material as a method of maintaining a bath at the ideal temperature. The concept below is essentially what I am looking at but using an amount of PCM to actually create the product.   [obscured]  /2012/03/19/perfectly-warmed-bath/ Would need to know feasibility, costs, effectiveness etc....to determine whether I pursue the idea. Anyone keen to help out?

I need an electrical engineer to help me design a PCB for a strain gauge indicator. I have most of the schematic already, but will also need some help connecting the already-designed circuit to the PIC18F, so some research may be in order if you don't know how to use the PIC18F. Attached is the schematic. Hope to hear from people soon and hope to get this done as soon as possible! :) Note: I will handle all the manufacturing myself.

Auto cad drawing of silicon ring I need a simple auto cad drawing of a silicon ring ring is .85 CM wide .15 CM thick 19 MM inside diameter It needs to have rounded outside edge and eased edge on inside....think wedding ring....no sharp edges see attached picture The only variation I need from the picture are small perpendicular lines approx .50mm deep, .50mm wide and 1.75mm apart around interior inside of ring. FYI: I am trying to make this ring a little more flexible and promote airflow to pass through when ring is placed on tool. I am open to suggestions. I need this done within 24 hours This project is for the manufacturer so they can make molds.

I have .pdf plans of an existing apartment which need to be turned into CAD drawings using layers and blocks I will provide. No site visits, no details, no 3D rendering necessary. Consideration will be given based upon proposed price and completion time. Some specifics: - Everything must be drawn using layers and blocks based on an example plan that I will provide along with the .pdf image and photos of the apartment. One existing/demolition plan, one construction plan, and one reflected ceiling plan will be drawn per the example and notes provided. - No annotation is necessary, but dimensions must match those shown on .pdf plans, and building elements must align in plan. - I have rough measurements of parts of the apartment. These will be used to scale the .pdf of the rest apartment to use as an underlay in AutoCAD, and drafter shall make intelligent choices about dimensions that are not provided. - Using PLines (polylines or shapes) to draw elements is ABSOLUTELY NOT acceptable,...

Hey, I need someone to hack the garment steamer process for men's clothing. This is for home/personal use only. Here is the steamer I have:   [obscured]  /site/conair-extremesteam-professional-handheld-garment-steamer-white-blue/6627506.p?id=1218763369275&skuId=6627506 I want someone to come up with a mechanism by which: 1. Men's shirts and trousers are steamed automatically using a hacked version of the device displayed above. Please note, the device is generally used in a vertical position and you have to control the rate at which the device moves over the clothing. 2. Both the front and side of the shirts and trousers need to go through the steaming process. 3. I would be willing to pay extra for the following services: a) Water is filled in the steamer automatically. Come up with a 3d printed module that replaces the original component and water is refilled in it automatically. b) A contraption device that flips the clothing to front and back. So I can hav...
