Ok I have in mind a device that I have a vision for. The technology, potentially, could be used for many applications. I have one idea right now that would form the basis of design. **note this product involves electronic components such as market available GPS module / antenae. I am willing to pay to get a very good product, however it will be broken into sections, each with various weighting in progress payments. Meaning, no point paying the full amount only to find it isn't feasible. So I propose the following overall breakdown : 1. Investigate Phase - Investigate the components I propose or suggest alternates, with regards to achieving the specified outcome. Investigate any patents (freedom to operate), or potential for patenting this idea. Provide feedback as to whther the idea will work from a technical standpoint, and approximate costings of components, with basic design and manufacture approach. (In a nutshell, can my vision become reality with components currently availabl...

We are wanting to develop a small scale educational simulator/model of a typical New Zealand rotary cow shed. Here is a video clip of a rotary cow shed in action.   [obscured]  /watch?v=jpsV-zTVzF4 Note: This project only requires the 'cows' to be developed. We are wanting to demonstrate how to maximise the efficiency in a rotary milking system. We are wanting to demonstrate the principles covered on this site:   [obscured]  /milking/in-the-dairy/rotary/ To do this we intend: 1. Adapting (rebuilding) an lp record player, something like this (  [obscured]  /watch?v=W60ZmpdiKlo) as the model rotary cowshed platform - where the cows stand. We will slow the speed down to the actual speed in the cow shed above and also make the circumference larger to cater for the model cows. 2. Obtaining some small scale model cows (we need to fit approximate 30-40 around the circumference). This is where this project commences. We want you to assist us by: 3. ...

integrate an infrared thermometer into a dog walking harness (see puppia vest for an example) that gives a temp reading in intervals. When the dog temperature reaches a target temp the harness sends either a sms message to the owner or gives a signal through a small light on the harness that turns red (indicating the dog's temp has reached a dangerous temperature)

Attached are 5 sheets that need to be re-drawn as electrical drawings(last 2 are same page). It is important that these need to be in normal, electrical drawing format with some line straightening, and standard symbols. If this does not make sense to you, then may not be a good idea to quote. I expect a first pass, then some revisions, then a final release to call it good. Hoping to get this square, as I have another 2 other drawing sets that are larger that need the same kind of work, and success on this gives you first dibs on the next. I am looking for improvement on the sketches to get to good elec-dwg format, not simply making a cad version of the sketches. Feel free to ask Qs. I will provide a title block for use in autocad format once awarded. -Mark

Have small hydro electric plant. Have ordered 5000 series Datakom controller for remote control of 1 turbine/gen set in power house. Should be simple system to connect controller thru internet or however, then to switchgear for opening turbine etc, causing breaker to close, then give control back to an already installed float/timer system that is already installed and works well. I have a switch gear engineer that wired all and been working with us for 30 years, that will be involved and we will all swap ideas and work together. Datakom controller can be found on the internet along with wiring diagrams for hook up, some of these on ebay. These are set up for diesel gen sets complete controlling. Our systems are not much different. Will need to teach us the software supplied by Datakom and may need to change or build a new one. We have never done this before and will be interesting. 2 plants. Then we may refine the system, find a factory to build controllers branded for us, have a pr...

I'm looking to design a prototype with electrical components These electrical components will be used for products that sell between 10$ - 70$ to consumers. So these are not big products. They are the size of regular home appliances. Some of these devices require electronics and some do not. Some are purely mechanical, or may not require electronics in the first place. I'm looking for somebody that can design a digital schematic of how everything connects, if at all possible. If digital schematic is impossible then a physical prototype will need to be made, however a digital copy would be preferred. I will reveal more once we converse a bit Looking forward to hearing from you gentlemen!

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...

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.

If any parts of this project is of interest to you ? please let me know. In this build project there was a decision to change the original plan for a house- Existing plans are for a 1- family home. Instead a 2-family home with one apartment on each floor will be built with the same exterior/shell. Further changes are: thinner outer walls: new wall thickness should be 20 cm instead of 40-50 cm which gives more inside space. The stair will be removed as the upper floor will have its own entrance. There should be 2 bathrooms in each apartment. 2nd floor should have its entrance on is south-east facade. That facade can also have windows added. 1st floor entrance can be moved along same facade or to SE or NW facade. Assume no walls are load bearing. Options: Sauna, walk-in closet Attachments: Set of drawings in pdf format Sketchup file. Pictures of plot and environment Picture with model of house inserted ( scale, perspective and placement are not perfect - only to give a...
