This job is to design and lay out a pcb that will verify thermal performance of a design in progress. The pcb shape and chip locations of the current design are attached in a DXF. Your job is to place resistors in the locations of the chips so that the power draw is approximately correct. Please confirm your design package can open the DXF before bidding. This will be a 2 layer board. The load resistors will go on top with vias under them. There will be copper pours on the back. Chips 2, 6, 6b and 9 should all have pours between 1 and 1.5 square inches. Other pours should be 2 times the length and 2 times the width of the chip. Do not coat these thermal pours with soldermask. You can choose 1 board voltage (either 24V, 12V, or 5V). Power and ground will enter through pads on the edge of the pcb. Please include vias in these pads. Use resistors from Digikey that are in stock. Resistor loads should be within 10% of the values listed below. The units of the DXF are mils. There are some ...

Hello, I need a proof of concept program developed on an Atmel xMega chip with TFT touch screen. The POC will read an input string and continually scroll the contents across the display in a structured format as explained below. In addition, there are some simple touch screen actions required. See attachment for requirements with images. Requirements: Initiate #9 logo on startup, display for 5 seconds Switch to main screen, which contains rotating display of text based messages The main screen contains three callout bubbles, with related message content and image Example screen: Screen needs to scroll content every 5 seconds, with top message being removed and replaced by middle message, middle message replaced by bottom message, and bottom message being replaced by a new message. Every 5 seconds, a new message is added and an older one is dropped off. For example, after 5 seconds, the example screen from above will now look like ? The screen will need to continu...

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 frequency will not be changed with a potensiometer because of the noise but from from the serial screen. 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 am looking to get a power distribution board made. It will be 3-4 layers and will have 12v input from top layer pad and distribute power to multiple pads across the board. I need 1 plane for 12v power, 1 plane for ground and top/bottom layers will have solder pads. There might also be layer for other trace connections depending on requirements for thickness of the board. There are 4 areas where I need 12v/GND pad on top layer to solder directly onto. The board I am looking for will be similar to this:   [obscured]  /forums/attachments/5/5/4/8/3/1/a7414440-197-pdbzmrrev5comp1.jpg But will not require all pads, it will be more simple. I can provide board size, measurements and hole locations. The board needs to be at least 1.6mm thick and have pads labelled for easy construction. Top layer will have text/logo that I will provide. Please tell me if there is any more information required.
