I would like to produce a book that reads stories out loud, similar to children's books that have farm animal sounds, but with sleeker/thinner electronics. The final product will read out around 2 hours of pre-recorded audio, have headphones, a way of detecting where in the text the reader is, and long battery life. I am looking for an electronics designer who can design the thinnest, most elegant solution and coordinate the Chinese/other manufacturers to deliver the design.

Attached is a concept for a farmer's market bag designed to protect produce as you shop. I would like someone to turn this general concept into a detailed design and then produce a prototype from the design files. I will need advice on materials and dimensions but I expect the bag to be sturdy and to be approximately the size of a large shopping bag. There are two versions in the attached please let me know which you feel is a better design. Please include in your quote: - Recommended Materials - Time needed to provide design files - Time needed to provide prototype - Total cost - Which design you recommend and why - Any concerns or limitations of the design Thanks and I look forward to reviewing your proposal.

Hello friends how are you? My problem is this: I am using a PIC16F887 microcontroller to program with C CCS pic c compiler. I have two push bottom one for and one for RB5 RB4. When I press RB4 a green LED should flash for 7 seconds, after which it goes and lights a red LED. When I press a push botom to RB5, the red light goes off and a blue LED blinks for 7 seconds, after which the program is reset, ports and flags are cleaned to start a new cycle. It is very important that must be programmed in CCS C

Hello, I need to get data from compressor machines via Internet. The compressors are from KAESER manufacturer and use Sigma control and sigma control 2. The objective is to connect a device via profibus to the controller. The device will get the data from compressor and send it periodically to a webserver or Database. We need an expert in Profibus/profinet technologies that can give us advice on how get the data from controllers via remotely. Also,If you already have a solution/hardware that do what we need, we will be interested in buy it and import it to Mexico. Thanks.

This project is specifically for the optimization of a Serit SP2636 Tuner using the ST Chip sets STV6110A and STV0903. We have the circuits working but do not perform as good as another similar system that we built. The Serit SP2636 is equivalent to the Sharp F7HZ0169 tuner can. The will require an advanced knowledge of DVBS2 circuit design including external hardware and the ability to optimize the software until the performance of this Tuner PCB matches our previous design. Experience in this area is a must.

The task is simple, recreate the teensy 3.1 with the same number of pins and specs, just make it as thin as possible using thinner pcb, chips on the back, etc. Bidders must provide evidence that they have experience designing and producing electrical chips. We need someone that can take this project through to a working prototype. If after thorough testing we agree that it performs to our satisfaction, we will look to produce the chips in some quantity but what you should bid for is just for building us a prototype.

I am a designer of of large (5-10m) kinetic (moving) wind sculptures. As I am not an engineer, I am looking to collaborate on regular basis with someone, who can take my detailed CAD drawings and descriptions - and develop complete Fabrication Blueprints, the Specifications and Materials List for each project, so I can bid it out. In summary, this means taking my detailed design concept and then engineering the details, connections and sourcing the correct components and parts - to create the complete Bidding Package. To get an idea of the type of projects, please see   [obscured]   and the CNN story:   [obscured]  /videos/tv/2015/01/28/spc-art-movement-wind-scultures.cnn Now I am developing a series of smaller kinetic sculptures (1m to 3m) and have several projects that need these kind of Fabrication Docs. FYI - the sculptures are mostly out of Stainless Steel and use ball bearings to facilitate motion. I would be glad for value engineering and improvement ideas. I...

Hey guys, We're an upcoming health company, and I need your expertise to help reinforce our weight loss formula for women. It is a protein powder that is going to have added natural fat burners in there, like green tea extract. I am looking for someone who can consult with me, to help improve the formula and make it a great product that will actually work well. As mentioned the 'base' formula is done, including flavoring - just looking for some extra ideas from experience professionals in the fields of what else could go in to enhance the product. Any ingredients must be scientifically proven to aid with thermogenisis, reducing hunger signals or helping with a weight loss plan in a practical way. So don't come at with me raspberry ketones :)

Need a DVR surveillance system designed and prototype. Preferably be able to record on a Flash drive or SD card. This system needs to be as small as possible. I would be completely fine with a USB port connected to a camera that plugs into a Flash drive. Need the system to be able to hold at least 2 cameras and record even after a vehicle or motorcycle has been parked. To conserve battery the system can go to sleep after a certain period of time of inactivity.

I have an idea that not only will be useful for me but many other people. I want to make a motorcycle lock with alarm, similar to Xena. This lock will have a remote key fob that will disable the electric shock option. The problem with the XENA locks is that, you can cover the speaker with your finger and the alarm can't be heard. After 15 seconds the alarm shuts off. Please respond with quotes and proposals.

I need to build a control device for something I'm building. I need to control a stepper motor to feed a wire, and then I need a 1-3 second delay, and then move a separate servo motor, to control a lever. I will build all the other components, I just need someone to provide me with all the electronic components (Arduino, Button, small readout Screen, 1 Stepper, 1 servo motor etc...). Here is what I would ideally like: 1. 2 button control (with a display) - 1st button will start the action (GO) - 2nd button will control count (So I would like to repeat the Go function 1 - 9 times) 2. So when the User presses the GO button, the Stepper motor will feed Slowly lets 360 Deg (I will need to able to change this in the code, because I need to specify the length and speed of the feed, which I need to measure after installation) - This motor dosn't have to be strong at all, I'm just feeding a small wire with this. 3 Once the stepper finishes its move I would like 1-3 second delay...

We have a small sensor to be protected inside a cylindrical housing and that will be periodically deployed. The sensor is a small laser scanner and the entire cylindrical housing can rotate which will allow the sensor to do a 3D map of its surroundings. Your task is to design the deployment mechanism for the sensor and which will have two actions. 1. the translation of some kind of hatch or cover, and 2. the deployment of the sensor itself The whole mechanism is to be powered hydraulically probably, but not necessarily, using a bi-directional hydraulic cylinder. Your task will be to design the mechanism producing a virtual 3D model of its operation using Autodesk Inventor. On acceptance of the job we will send the CAD drawings of the space available, the housing cylinder and the sensor as well as more detailed specifications.

Design an attachment for the SSI Schaefer trash bin where a homeowner can put on the attachment when required to dispose of yard waste or other items that won't fit in the trash bin. The attachment must be able to hang on to the can when being dumped by an arm from the side of the truck. The can is positioned with the wheels against the curb and the front of the bin is the downward side when dumping. The unit will be designed with the ability to stack for mass production and ease of shipping multiple units simultaneously. I am interested in taking the design to my trash company to see if they would want to buy a number of these attachments. The deliverable will be a powerpoint presentation with the specifications and graphics of the design.
