You must draw the complete hardware plans. The choice of components is yours. I need a working prototype. butt if i can have the complete hardware plans . I can submit it to a manufacture. must work on Android os. butt if you have a better idea. all listen. IM LOOKING FOR A HARDWARE DESIGNER. ITS JUST A PICTURE .(drawing) IF YOU COULD BUILD ME A WORKING PROTOTYPE. TELL ME WAHTS THE COST OF A PROTOTYPE.

Currently seeking an electronics engineer to design a custom circuit / PCB based on a working Arduino PID controller prototype. (MCU programming is not part of this solicitation but may be involved in follow-up work.) Budget negotiable based on experience & expertise. Size: Approximately 5cm x 5cm, 1 or 2 Layer Input Power: 120VAC @ 60Hz MCU: ATmega328 The device will have various inputs and outputs (buttons, sensor, buzzer, LEDs, etc.) that will be PCB-mounted and/or attached via PCB-mounted connector. It will need to have an integrated power supply as well as a solid state relay circuit (opto-isolator / triac) for controlling a separate mains-powered device. It should also include safety features common and/or required (UL, CE or otherwise) for use by consumers. The design must follow best practices and be verified by common rule checks. Deliverables include a complete technical specification (gerber files, schematics, design files) and a detailed BOM outlining the most...

Part 1 - Taking our specifications, the freelancer will calculate the appropriate ferrite core dimensions, winding and circuit configuration to allow the correct frequency performance to be achieved. Part 2 - The freelancer will source the closest ferrite core and wire for the windings available to the theoretical values and formula and perform a further calculation of the frequency performance and efficiency. Part 3 - The freelancer will produce a bill of materials and a design drawing as the final deliverable. A final payment will be made once we have manufactured the prototype and it has achieved the calculated specifications.

A 1hp electrical motor whose coil got burnt needed to be rewinded. First, the casing of the machine need to be remove to unveil the burnt coil. After which the burnt coil can be remove from the armature (noting the number of turns and winding pattern in the armature). Then another coil are wound inside the armature to make the machine works again.

I have in idea and need to develop and build a small prototype just to prove a concept. I live in Australia. Sun here is very strong. But I've noticed that parts of grass in a tree shade stay green for the whole summer and you may save time and money watering it. There is shade only for two hours, but critical western sun hours. So, I want to create a simple light mobile device that can cover grass with shade for specific most hot times. Small sun panel with brightness sensor and small air pump which blows air into a parasol to create a shade for grass. Or, a motor and rails to cover grass with light material protecting from sun rays and then bringing it back. This device must be easy to carry, easy to install and adjust, cable free and suitable to stay outdoors. Anyone interested being a part of this project or simply developing a working prototype - please, let me know.

I am looking for someone who can build our second prototype. We need a screen that can be easily visible in direct sunlight, bluetooth technology to talk to our mobile app for screen to display things, and a magnetic backing for the device to magnetically attach to something. All needs to be weather-proof because this device is meant for outside use, so perhaps a protective casing around device that will not inhibit the visibility of what will be displayed on the screen.

Using a Rasberry Pi 2, monitor a analog input and using software compute commands needed to adjust a speed to maintain a set value. For example, if the set speed is 100, then we need to see if the actual value from the analog input is greater or less than this, apply a delay to adjust the response to match the real world response time. This value is then inserted into a RS485 ( Modbus) string and sent to a speed controller. This is a continuous process and is very slow response (5 seconds).
