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.

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.

We are looking to hire a firmware developer to assist us on a project to read data from a CCD array using a ARM Cortex M3 microcontroller. We already have a working prototype from other freelance developers/open source designs and for this fixed price project we just want someone who show competence in understanding the project and help us migrate the firmware from one demo board to another. This job post is just to identify right freelancers and test their skills before we start working on a hourly basis. Experience in hardware oriented / embedded firmware development - Excellent Programming Skills in C language. Some experience with GUI using java, python etc desired too. - Should have working experience with Atmel/Freescale/STMicro development tools - A major plus if you have previous work experience with CCD - previous experience on low cost demo boards from NXP and TI - Knowledge of ARM Cortex Controllers & Digital Hardware Circuits is desirable - Should have excellent de...

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 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...
