Looking for intermediate to expert in the area of digital circuit design, schematic entry, pcb design and prototype development for a small design based upon the ESP8266 chip. The board will sample an analog signal, process it according to set criterion and send and receive data to a server over wifi. Will also receive data over wifi to be sent to a DAC and/or other device. Prefer those with experience in both hardware and software design for this platform. Will need to develop prototype as well as troubleshoot both hardware and software for the project. Would be helpful if applicant is very familiar with Linux software development in C and C++. Arduino development and other microcontroller project design and implementation a plus.

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 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.

hi. this project which is attached is about power computer. they are four things to do in this project . the first is do flowchart for control vhdl. the second is to use software call (quartus II 9.1 ) for Vhdl. the next step is used components for example( add-sub, multiplexer, register, and controller which is must be same as the flowchart design. the last thing is, you can use software call( luichart to draw the flowchart)
