I need somebody who is an expert in automation to design the control system for our CNC machine. Details of the machine will be provided later. You need to sign an NDA. Most importantly you need to work independently with little inputs from us. I am looking for someone who has experience in CNC machining Centres, 3D printers and Scanners. Please give examples of your past projects. This project might need longer commitments depending on your skill sets.

I am working on a project and need an electrical engineer to help with the physical layout of a few components. The circuit is simple and only involves a surface mounted LED on a MCPCB, a driver (maybe?), a switch and a battery pack. Your expertise would be in design for manufacturability and a good knowledge of off-the-shelf electronic components.

My project is to create synchronous rectifier for automotive alternator. I have already finished with the hardware (picture attached), now I need help with the software part. Basically it is three-phase bridge, created with low resistance MOSFET transistors, which need to be activated/deactivated at the precise time in order to turn input three-phase AC voltage into output one-phase DC voltage (12V). No voltage regulation is needed, this is done externally by dedicated voltage regulator, which does not require any interaction. The hardware will be controlled with Texas Instruments F28069 controlSTICK microcontroller (this is a must), so I need somebody with experience in programming Texas Microcontrollers. For more details, please do not hesitate to contact me. Already completed: - GPIO - ADC

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 (http://www.cburch.com/logisim/download.html) 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.
