We need a PCB as a timer for managing a 36W Led Panel and a 3,5V water pump Input: Adaptor 24V/3,5A constant voltage Output: LED panel (36W but drivers need 24V, 3,5A) // 18hours ON / day Ouput: water pump 3,5V to 12 v max // 2 minutes every hour MCU needs timing function You'll prepare the Gerber files and the screens for the PCBs and also a detailled BOM You'll make a small sized PCB and keep in mind the solutions to make it cheap. Thanks

Like to design control board to power a split AC unit fan with out all the crazy items that we need to adapt to use these new inverter power fans. Right now we are gutting the compressor to get control panel / inverter and do not need this once designed. Fan is 36V with 5V control signal, variable speed.... We would also like to be able to over ride the limits of the cooling from 64 to 58 degrees in these units on a seperate board, some companies have done this, but the application of how it work is very bulky and not high end clean look. So if you think you can help lets link up.

We are looking for a capable electronics engineer who can design a CMOS Board Camera based on an Aptina AR0134, MT9M021/31 or similar sensor (1.3MPixel). The camera will operate in snapshot mode, taking an image on demand from an external trigger. (max 2 images per second) It should have a good quality board bayer interpolation, either using a dedicated Image Signal Processor OR an FPGA. It should output data via a Digital Data Bus as RGB or YUV (RGB preferred) The camera will be controlled via SPI, I2C or similar. Advanced camera features such as Auto Exposure, Auto White Balance, Auto Focus etc will not be required. For development and testing a board mount lens will be used. At a later stage the board will eventually be fitted behind a zoom lens module, but this does not form part of the current requirement. If you have previous experience with a similar project and can complete this design producing a camera prototype with a high quality image, then please reply indicating your former experience with CMOS image sensors and also indicate a "ball park" cost for your work. Also please suggest your preferred sensor device, and option for color interpolation. Firm Specifications will created and agreed by both parties before committing to firm price.

This projects involve designing a single circuit board assembly for various components. I currently use an arduino, HX711 amplfier and wifi module as 3 separate units as a prototype. The unit will accept an input signal from 4 array strain gauge assembly, exactly like a bathroom digital scale. It will use 4 purchased 3-wire strain gauge load sensors . The circuit should amplify the signal, clean and process the signal using a low-cost microprocessor (i.e. Arduino Teensy, or alternative) and then send the signal via a wifi module also incorporated onto the board . Combine these into one circuit board: - Strain gauge signal amplifier (example: HX711 Load Cell Amplifier) - Microprocessor unit (example: Arduino Teensy or low-cost alternative) - Temperature sensor - IoT low cost wifi module - Run's off battery or an AC adapter that plugs into the wall. The design does not have to use the same components I prototyped with. I am looking for a low cost mass production model that achieves the same purpose. If you have done a similar project with  lower cost components, that is desirable. Expected Deliverable: A circuit design on a single board that achieves the purpose above with a low-cost component BOM. No physical prototype is necessary.

Looking for an experienced audio electronics engineer for a simple circuit and PCB design. We have two products needing attention. The first is a passive version, and the second is an active version of the same device. Very simple stuff, we just want to make sure we get it right the first time. Work for hire, we own the design. We need you to design the circuit to work to our specs, and create a PCB design that implements it. This is a ridiculously simple circuit, so quick and easy money.
