Asking for bid on a project LED Light Panel , PCB design.... End result desired is an EAGLE CAD file or equivalent. Include the necessary mounting positions for surface mount components. Also include the correct resistor and communication channels for LED color groupings. There expect to be at least 5 groupings for example.. I will send the LED light configuration to the finalist. Include in the design independent channels for each group of colours and addressable RGBs. this could be an ongoing project as we would like to innovate as we test and learn. Design the connector for integrated circuit to control lighting parameters. Include pin outs.

As a first step in creating Electrochemical etching machine we need a proof-of-concept experimental platform. It should : 1)Provide pulses from 10us up to 10ms of DC current to load (U=15-40V, I=100A max) 2)Have all adjustments to change pulse time, pulse voltage 3)Have outputs for oscilloscope to detect real current and voltage forms For the very beginning of the work, a circuit with rectifier, a mosfet, mosfet-driver, pulse time adjustment and inductive load overvoltage protection will be enough, so we can test your skills and get early concept. The load is a gap between electrodes, filled with electrolyte (NaNO3 water solution), and has complex resistance (active, inductive, electrochemical + inductance of power wires) If the proof-of-concept shows that the idea is right, we can offer long-term work for creating full power, complete etching machine

Looking for an experienced Electronic Circuit Designer and Microcontroller Programmer who has worked with Low-Power Microcontrollers like MSP430 and PIC. We are interested in designing an electronic circuit consisting of a low-power microcontroller to sense, collect and transform the data. The microcontroller would be connected to a Bluetooth Low Energy (BLE) chip to advertise the final desired data to smartphones. We want the whole circuit to be working on power generated by Smartphone's audio jack. Further specifications available for applicants to review upon request.

Together with our chinese partner we have developed a new MP3 player for kids, where they used Keil C for the programming of the hardware (PCB and display). Now their software engineer quit the job and they do not have a replacement. Therfore we are looking for a Keil C expert to continue the work or make a new software. The development could be supervised by our chinese partner (chinese speaking people prefered) or by us in Germany (english speaking people prefered)

Hi! We are developing a new a new Bluetooth headphone and need to find an experienced engenieer who can help our factory to find a solution around app control. We want to develop an app where the user can adjust the sound volume, bass, discant etc through the app instead of pressing buttons on the headphone. Our headphone will also have some more advanced functions such as multi channel intercom and noise cancelling functionality. We want the app to support that kind of adjustments and options too. We are looking for someone who can help our factory to find the right chipset and software to be able to control the headphone via the app.
