Need to design the gate control circuitry for an Multilevel Modular Clamped Capacitor Converter. The gate circuit will be using HCPL 3120 optocouplers and need to know how many required. The optocouplers will need an input resistance into the device and an output circuit with the use of a capacitor in parallel with a separate power supply for the 3120s and also an output resistance , diode and another resistance so to calculate dead time and assure the MOSFETs charge properly and discharge quickly through the resistor. I would need a calculation of the resistors, diodes and capacitors needed for the circuit. I would also need a schematic of the connections required and how to be connected. Discuss with me for further information of what you need. I will send all the specs of the converter when discussed. Require full and correct operation. Need urgent completion, one day, no time wasters!!!

We are working on building IoT prototypes using various hardware and clouds platforms. We are looking for a experienced freelancers to speed up our process. You will work with our technical team with remote access. You may have to work on hardware platform from scratch and connect the hardware to cloud running some application on it. Application won't be too difficult. It can be discussed later. Hardware platforms we have are Raspberry Pi, Intel Edison, Linkit One, FRDM, CC3200. Options for cloud platforms are AWS, Azure, IBM Bluemix, Thingspeak, Sandbox etc. Programming languages we are looking forward are C, Python, Node.JS. You can even suggest platforms of your choice which can be helpful for building industry level applications. Please mention your experience with IoT in the proposal.

I do need someone to analyze frequencies captured on the ear and recorded something similar to those on the file attached. There are many more hours of recordings captured - this is only an excerpt. Analysis should include - frequency range, source identification and all details you can get. It should be in the form of a report. If successful this could turn to long term project as the company will be in need of such an employee. range is open. please apply only if you are sure you can offer good service 100 % success. I will send the file to the people who will apply. Please send me your email address.

We are getting ready to make the switch to 3D Control Panel Design and need some help getting some "Parts" created in 3D from 2D drawings, spec sheets and photos. While some of our suppliers had 3D files available, there simply are some we need to create from the above items. In most cases, we just need a representaion of the part with minimal detail. Once in awhile, we need more detail, especially if its a part we will be using often. This would be an ongoing relationship as the need will come up fairly often.
