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.

Greetings, We are in the midst of developing a wearable device for infants to measure BLOOD OXYGEN, HEART RATE AND BODY CORE TEMPERATURE. The wearable needs to be bluetooth integrated where the data is remotely transmitted to a Windows application where the staff will remote monitor device data. We prefer using Maxim sensor and a reliable but easy way to measure body core temperature. We need product design help as well to enclose the PCB. The PCB will be charged either by Micro USB or magnetic clip like most smartwatches. All interested participants SHOULD have the following experience: - MAXIM PULSE OXIMETER SENSORS - HEALTHCARE WEARABLES FROM CONCEPT TO PRODUCTION FOR INFANTS - PRODUCT DESIGN FOR WEARABLES FOR INFANTS Looking forward to all proposals.

I've recently started the creation of an new electronic device, and am I need of assessment on the process. I currently have the circuit schematics, pcb layout, and design, of the electronic device. I'd like someone who can evaluate it's compatibility/functionality, and if found inadequate, redesign/remake, circuit schematic and PCB layout, program the micro controller, as well as, evaluating and debugging an inicial prototype, when possible.
