Looking for an experienced Electrical Engineer/Printed Circuit Board designer to refine an existing PCB for a consumer electronics product and prepare it for mass production. Project is ongoing with a target launch date of winter 2017. Prototyping milestones will be given for design, preparation for manufacturing, and simulation/testing. Guitar experience (as a hobby or professionally) is favorable. Experience with piezoelectric sensors also favorable. Role requires strong interpersonal skills, time management, and ability to collaborate with a multi-talented team. Final deliverables are a working PCB and all associated schematic/layout files necessary for production.

Hello i am looking for a hardware circuit/schematic design engineer who is very good is designing circuits/schematics. Basically i have a schematics which needs to be modified. i have one sierra wireless aircard 320U connected to the USB1 i have one TL-WN722N wireless USB adapter (wifi) connected to USB2 your tasks 1) now we will use Sierra Wireless Airprime MC7355 to be connected to mini PCIe M.2 slot hence we need to design a circuit so that host can talk to the modem on mini PCIe slot and obviously the modem must be connected to the SIM card slot. 2) and wifi must communicate with the host with some reasonable bus. in other words this usb must talk to our hardware 3) we need to add RS232 , RS485 ports to the schematics as well. Pre-requistes: please make sure you have worked on designing circuits involving sierra wireless airprime with PCIe slot and wifi as well Regards

For this job, you will be required to complete a total of 5 lab reports (Labs 6-10) and simulate digital logic circuits in a program such as Logisim ( or LogicWorks or any digital logic simulator. You must use simulation software to check your work and build schematics, saving schematic files, as well as taking screenshots of the schematics being simulated successfully. You will need to save every Logisim/simulated schematic file (.circ) as you build it while completing the steps of each procedure in each experiment and submit with a well formatted report. When submitting for review, you will send the report, the .circ file, any screenshots of a simulated circuit, and any other relevant information/data. Laboratory Experiments 1-5 have already been completed. You will only need to do Experiments #6-10. View the EXAMPLE files to see how the work was done and how to set up and format properly. I have included COMPLETE examples of Labs 2, 3, and 5. You can view INCOMPLETE and possibly inaccurate Lab examples 6, 7, and 8. However, these may be incorrect results and still do not have the simulated digital circuit. The only real work is completing the questions, any calculations, and creating the schematic being simulated for the lab experiment. Skills required: Electronics, Digital Logic, Circuitry, Knowledge of Components, etc. Compensation is negotiable depending on your skills and how well you do on the reports.

We need a schematic for a digitally controlled variable power supply that can switch between AC and DC and can switch polarity for DC voltages. Needs to be stable and precise. Voltages need to vary from 0 to 30V, and 0 to 5 amps. This needs to all be controlled by a Raspberry Pi 3. We can handle all the programming - just need the circuit design.

Looking for an EE with consumer electronics products background on a multi-week project to design a system to detect the rotation distance and direction of a ring. The ring is slow turning and low resolution. Solutions are either optical encoder or break-beam encoder (open to other suggestions!) The design must be small (product is size of a golf ball), energy efficient, and low cost. Looking for full end-to-end design including concept, schematics, layout and component selection.

I'm looking to create an all in one VR device similar to this: Looking for someone that can create the internals of the device, should be similar specs to the link above. This device will run Android. Basically looking to put the internals of a high end android phone into an all in one VR headset. If you're a product designer too that's even better.
