I need a program for an Arduino board so that it can generate 4 types of PWM. 1. Sinusoidal pulse width modulation - SPWM 2. Selected harmonic elimination - SHE PWM 3. Space Vector PWM - SVPWM 4. Hysteresis band current control PWM The user must be able to select the type of PWM that he wants and the frequency (1-200 Hz). The system is intented to work with a SINGLE-phase inverter. The Arduino board that will be selected will be anyone with an ATMega micropcessor. The final deliverable should be the arduino code files with extensive comment documentation.

In need of an electrical engineer to design a preamp for a dynamic microphone (using a DIY board off of EBay is fine, audio fidelity is not a major priority), as well as a volume control for a set of headphones. The project enclosure should have the following: 1. A 4-pin XLR connector for headset (2-wire mic, 2-wire headphone) 2. A 6-pin XLR connector for the following: a. 2-wire incoming audio from external source b. 2-wire outgoing audio to external source c. 2-wire for 12V DC 3. A volume dial for headphone volume control 4. A push-to-talk button to un-mute the mic 5. A beltclip 6. No external mic controls are needed. A set-and-forget it internal pot can be utilized. This is for a custom intercom beltpack with specific needs.

We need to have the layout done for a small USB 3.0 camera. The camera uses a Cypress CX3 and an Aptina image sensor. The entire camera has to fit on a PCB of 29mm * 29mm, where we need to leaf a space of 1.5mm around the perimeter. The 4 corners of the PCB have to be rounded with a radius of 3mm. - The schematics of the camera is available in Altium. - All the footprints are available. - An initial placement of the major components has been done to verify if the design fits. - The layout has to be done with a 12 layer PCB. - With drilled via from top layer to bottom layer - With drilled via from first inner layer to last inner layer - With laser via from top to first inner layer and bottom to last inner layer If you are interested then let me know, I can send you the schematics and the initial placement of components in PDF format or possibly in native Altium format. Best regards

We are looking for consultant that can help us do some fairly basic electronic design work. We have budget for this project and are ready to start immediately. Essentially we want to take an existing reference design for WiFi enabled smart plug (   [obscured]  /tool/TIDC-SMARTPLUG-WIFI ) and perform the following modifications: 1) We would like to have two (2) completely independently controlled and monitored egress power ports. Per the documentation, the relay, meterology and microcontroller per egress port is "scalable" so this looks to be a fairly simple task. We would ask for help both with the hardware design as well as the software modifications to be able to control/monitor the second port similar to the primary (note: I am linux software engineer with 20 years of experience, but I have never written hardware drivers). 2) We need to add an electronic or mechanical switch: the board will be housed in a lockable chassis, I just need some notification when the ch...

A harmonic filter was built in simulink, all that is needed is the tuning of the pid and capacitor of the voltage source inverter which would allow for the source current to become sinusoidal. compensation currents and reference currents must not change, if pid is correct hysteresis should occur where both currents track each other in a hysteresis band. This is an easy job and requires only 1 hr of someone who has experience. I need this done asap, very quickly.

I need someone to design a quadcopter with an autopilot function. The autopilot needs to be a program that keeps the copter flying around a device connected by bluetooth (or an RFID tag), stabilize it if knocked, and land safely when the battery is low. The copter will be in a small 70mm in diameter "shell" that will be designed by another individual in conjunction with the development of the electronics. Along with the copter, I will need an RGB LED light that will change colors based upon the gyroscopic sensor, temperature sensor, and accelerameter. I would also like a microphone to be built in so the copter and LED can interact with music being played. I will need a prototype made and the ability to manufacture in the future.
