I need a program for an Arduino board so that it can generate 2 types of PWM. 1. Space Vector PWM - SVPWM 2. 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 frequency will not be changed with a potensiometer because of the noise but from the serial monitor. The system is intented to work with a SINGLE-phase inverter. The Arduino board that will be selected will be arduino uno. The final deliverable should be the arduino code files with extensive comment documentation.

This is to hopefully find and start conversations with the right company/individual. We are looking for a firmware person to join our team for a security based project based upon a Zigbee mesh network. Experience in this type of topography required (including pairing, encryption, fail safe messaging, etc.). Also experience in Sharp's memory LCD (2.7") and either custom fonts or Ramtex icon and font package. Our current processor is a Microchip PIC8, which we need to upgrade to either a PIC16 (with enough RAM support to buffer display in memory) or switching all together to an ARM processor (which we would then need to scrap any code written so far). We are open to either a standard work for hire contract, or even possibly an equity/full time position with our company in Wisconsin or Remote. We are really looking to build a solid team of individuals as we launch this project over the next 6 months.

Our devices are connected to the Wifi network via Texas Instrument CC3000MOD wifi module and MPS430 as the microprocessor. We are seeking an engineer to transform our C code from cc3000MOD to the new CC3100MOD. We need re-create the initial peering between the Smartphone and the devices while maintaining our app logic. Today the CC3000 uses the "smartconfig" peering method ? we want to mode to the cc3100 AC peering. We would need to go over the connection commands (burned to the MSP) and translate them to work with the cc3100.

Design a Proof of Concept (POC) working prototype of a test chamber using Proportional Integral Derivative (PID) solution to digitally control the temperature, pressure, flow rate and volume independently. Generate a User Interface (UI) to monitor and regulate the above parameters via a PC/ tablet device. Test chamber will have pressure control valves at both the inlet and outlet to regulate the pressure differentials during operation. Finetune the PID control and UI system after POC prototype is built and tested.

This is a small project to design an ultrasonic range finder using a single transducer. I would like to find a designer who's willing to not only play the role of a designer, but also spend some of the billed hours explaining the design to me in Skype video sessions. The main priority is to design the schematic, implement the circuit on a breadboard and test it. The second priority is to design a PCB and going through manufacturing and assembly. DESIGN REQUIREMENTS - The circuit MUST use a single transducer to both transmit and receive ultrasonic pulse train. - The transducer MUST still be able to function function after being in contact with water, but operating under water is NOT a requirement. - It MUST be possible to fit the transducer in an enclosure such a way that water cannot enter the enclosure. - The range finder MUST have a range of 10cm - 2m. - After each measurement cycle the circuit MUST be put in sleep mode in which power consumption is negligible. I hope we can wor...

Hi there, We run a science enrichment program and in the course of our work we have developed numerous toys that we use in our program. We know the kids (our clients) like them because when the toys break the children come back and ask us to fix them. We have also sold some kits that we put together. We are looking for someone to help us take these projects that we have developed in-house and turn them into products. We are looking for someone interested in working with simple materials, has some experience with electronics and likes to think out of the box. Some of our projects are made of cardboard, paper and so an interest in folding and working with cardboard is desired. We need to solve some design issues in taking this to market. We are interested in simple clean design. We have a web site with some samples of our work and will share information with interested designers.

The screen size is from 8-11" inches big and it will have a capacitive or resistive touchscreen to be used with a pen. Resolution does not need to be high. And grayscale or simply black and white is enough. The finger and hands of the user will not have any effect on the screen. By using the pen we can draw on the screen. The pen should be adequate to the type of touchscreen (capacitive or resistive) The drawings on the screen will stay for as long as possible by means of a small battery so count on 1mAh or so but we can go higher for an initial stage. I depends on the whole system consumption so try to choose low power components. There will be a reset button and when pressed the screen is cleaned and all info is erased. Before erasing the screen the information should be stored in memory. A second button will be used to show the stored drawing in memory back on the screen. Any subsequent reset will overwrite the memory info with the info on the screen at the time the button...

I want to build a 2-bedroom cottage in a remote area where sun is aplenty (Siem Reap region in Cambodia), but where I cannot count on a reliable utility company. Therefore, I need to put together a self-sustainable source of electricity (110V-50Hz) for the lighting, fridge and some electronic devices (TV, radio, computer, etc.). I estimate my needs to require at least a battery storage capacity of 3KW battery storage (looking at the newly-announced Tesla Powerwall, but a bank of gel deep cycle (200Ah) batteries could also do the job. I did some research and found most of the major components I need (PV panels, MPPT charger, batteries, Inverter). I am looking for someone qualified to: 1) Validate my components for compatibility and balance. 2) Provide a more complete BOM, including jump cables, wiring, junction boxes, switches, remote control panel, etc. 3) Draw a detailed diagram of how the various components are attached to one another, with proper minimum distance between them if...

Hi Guys, I am stuck with MOSFET over heating issues. I really need to resolve this fast. Behind schedule and over budget. How is $100 to the first person who steers me to success? Details are here ...   [obscured]  /support/power_management/non-isolated_dcdc/f/196/p/421954/1508657#1508657 I prefer not to award this to any single person, and tie this up longer. I need suggestions / answers immediately. Once I get the circuit to work from your guidance, I can award / pay. I am hoping to find a power expert that has seen and fought this fight before, not just anyone who is tossing out random suggestions (although I would take that now)
