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 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...

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.

I require a bespoke KVM device, with the following features: 1) In-line functionality - The device must sit between a computer and its KVM peripherals, so that a local user can make full use of the system, as well as a remote user. 2) Video support - The device should support D-SUB VGA, DVI-D and HDMI connectors. 3) Keyboard/Mouse support - USB support only required. 4) Storage - The remote user must be able to provide files to the computer. This should be implemented by uploading files to the device, which then presents a USB storage device to the computer. This should include the presentation of an ISO image as a USB CD/DVD drive. 5) Connectivity - The device should have at least an Ethernet connection, but ideally include a 3G/GPRS module for use in the event of wired network outage. The primary non-functional requirement is minimum cost per unit for production. I would need to see at least a high level design of the hardware and software before I could accept a proposal. Su...

This posting is for the delivery of a schematic and PCB design and layout of a 40W, 110V, 60Hz sine wave inverter. This includes design documentation and all files (GERBER, etc) required to manufacture and modify the design in the future. The incoming power will be from four of the attached lithium-ion batteries, arranged in a 4S configuration, which are already regulated to a 4.1V maximum charge by another circuit. Therefore, maximum input for the inverter circuit will be 16.4Vdc. Circuit size should be no more than 3x2x1" (LxWxH), and the smaller the better in all cases. Height is of highest concern, but overall size should be as compact as possible. The inverter will be in an IP56 minimum container, so heat generation is an issue to be mindful of - heatsinking to the outside is possible, but a design that generates little-to-no heat is ideal, and should be possible with this low of wattage. Audible noise should be non-existent - transformer selection should be of high quali...

Hi i am looking for the multiple loop feedback structures that should be applied on continuous time current mode filter and design equations for that project. In mlf there are two topologies FLF and IFLF. we have to apply the combination of both of them in a single topology and design the equations. If any one are good in this topic please respond or you can contact me. Thanks..

Our company is seeking a freelancer to design and build a data logging board that will be used in an exposed outdoor environment. The device should be housed in a weather tight enclosure. The enclosure will need to have a bulkhead connection in order to allow a water hose to be connected for pressure sensor readings. The device should also be capable of storing readings from a pressure sensor which detects water pressure. The readings would ideally be stored onto an SD memory card for later retrieval. The device should have an external ON / OFF switch. The device can be made using an off-the-shelf device such as an arduino if the cost is less than designing a custom printed circuit board. In summary, the device should have the following operating characteristics: -- Weather tight enclosure suitable for use in an outdoor environment -- Bulkhead connection for water pressure connection -- External ON / OFF switch -- Pressure Sensor capable of being in continuous contact with ordin...
