hello there, I have a small computer product I'd like to get its circuits designed. Submit a bid only if you have the expertise and have worked on things like mouse, touch pads, and design softwares. Will consider more if you've also got software expertise to integrate this with the PC & Mac. Best Regards Eric

Currently have a two jointed (two axis) armature controlled by RC servos. The servos are currently controlled with sevo controllers but I would like a gyroscope to move the sevos automatically to keep the cameral platform level when moving the stick around. Also would like some kind of switch to turn the gyroscope off and move the sevos manually with the servo controllers. I would prefer if off the shelf or commercially available parts were used. There are several types of inexpensive gyroscopes available. The ultimate long term goal is mass production of this unit.

We need a high efficiency AC Solid State Relay (SSR) for a 120-600 VRMS (40 A max) load. Currently, we are using a triac output which has an approximate 1.1V drop during conduction, or roughly 42W of power being dissipated by the relay at maximum load. I want to drive this power dissipation down to 1W for the relay so we will need to go to a different relay design. The trigger voltage will be 3-32V DC. The dV/dt value must be greater than 600 V/us and be able to withstand transients and an electrically noisy environment. The bid should include design, simulation, prototyping and measurements taken directly from the design.

  [obscured]  /design/1521/11 has a tutorial named "Standalone (Bare-Metal) USB Device Tutorial". Translate this project from ISE to Vivado. Familiarity with zynq preferred, this project has potential to grow as it will later be expanded upon. For this project just the conversion. Keywords: FPGA Verilog Zynq Vivado ISE Xilinx (and maybe embedded linux) For debug etc this project runs on Zedboard, please advise if you have zedboard or equivalent. Otherwise we may need to schedule for screen sharing.

I need someone that is experienced in Eagle CAD to make a change to an existing PCB. This change consists of hooking up three new low power MOSFETs, adding 0603 three resistors, and rewiring a couple of nets. I will provide both the eagle schematic and PCB, plus a pdf of the new schematic with the changes highlighted. If we are happy with the results, this will probably lead to future jobs too. I'm a circuit designer but I'm not very good with Eagle. So no circuit design experience needed, just lots of experience laying out printed circuit boards with Eagle CAD. Thanks.

We need three white papers developed, one for each market segment, that shows how to use a Solid State Relay in a typical application. The markets are as follows: 1. Aerospace/Defense 2. Medical Equipment (and diagnostics) 3. Transportation/Agricultural Equipment For each whitepaper, we need a problem to be stated (as in motor/heater control, etc...), a circuit design, simulated or tested, results and discussion of the results and comparison to other similiar designs. We are planning on using this for marketing and sending to engineers in these industries to help give them better ideas on how to use our products or give them a starting point or new ideas for the application of our products and/or technical knowledge.

I need a breadboard circuit with the final schematic and the right values and BOM. We need an AM detector which has 120kHz at 2Vpp and is modulated with 32kHz, 10mV. The demodulation sub-circuit has a diode and an RC which has to match. Due to small Signal to Carrier ratio, we will get a huge ripple which needs to be filtered out. The 32kHz comes with 8 periods per bit and has to create an output level of 100mV.

I want to design a iPhone 5 Case that has slots to accept power from the following potential power cords: +iPhone 4 +Apple notebook +Regular USB +Samsung Galaxy S4 +LG G2 +Nokia Lumia 520 +HTC One I want the case to have slots for each of these cords to plug into. Each slot would be covered by a plastic fin. My hunch is for this to work, each of these slots could lead to a central charging pad (see enclosed photo of charging pad) that is sandwiched between the phone and the case (ie the charging pad is on the inside of the case). I enclosed hand drawn sketches of what I had in mind. Please pardon the chicken scratch. If you have any questions let me know. Need electrical engineer to design manufacture ready CAD for this. To apply, please send application listing experience, word 'elephant' towards the beginning of your application, and whether you think the charging pad is the best solution for this challenge. Don't do hours of research upfront to find the best solution for this a...

I would like a circuit designed to produce a current with a specific voltage, waveform, and frequency. The design will be used to build a prototype. I will request a confidentiality agreement, provided by my organization, for the project. I may request several circuit designs afterwards with slight modifications, or seek advice when assembling the circuit.

I need circuit designed for a solid state relay, optically isolated from output to input to 7.5kV, for a load voltage between 125-250VAC (60 Hz) under a 40A max load. It specifically needs to have less than 100uA of leakage current when it is in the "position". It must also have a tolerance to transients with a dV/dt > 600 V/us and input DC voltage range from 4-32V. I need it designed, analyzed, and tested under a 15A load along with all testing results.
