We need an interface cable designed and prototyped that will incorporate three channels of charge mode amplifiers with gain and a single channel 15W speaker amplifier. This cable will connect a device containing two piezoelectric sensors and one speaker to an existing embedded system. Currently, the embedded system connects to a slightly different device which contains a speaker and two microphones. The goal is to include the electronics in the prototype cable that will interface the new device to the existing embedded system. We would like this designed and fabricated ASAP and would like five cables made after we have tested the prototype. A non-disclosure agreement will be required to work on this project. See attachment for the requirements. Applicants should be well versed in analog circuit design and PCB layout.

Project Specification 1 Project Overview An Electronic Speed Controller (ESC) for Vertical Take-off and Landing (VTOL) Unmanned Aerial Vehicles (UAVs), such as quadrotors and hexarotors. Contractor is ordering from Manufacturer to construct, based on Mystery ESC 40A design, similar ESC controller with improved functionality. ? Performance identical to Mystery 40A ESC. ? Data output through I2C bus is required, specifically RPM of motor, temperature and current. ? PID control of motor RPM is required, so the ESC drives motor at constant RPM through during whole mission. ? Mounting holes have to be added to the design, to attach the ESC to the airframe. ? High-end components are to be used. ? Custom firmware based on open source code ? ESC has to be able to receive commands through I2C bus 2 Project Details 2.1 Inputs/Outputs ? Input Data: PWM signal, commands from 40Hz to 1kHz ? Output Data: I2C bus (3,3V logic) ? Data inputs (PWM, I2C) have to be isolated from the battery ground (optoi...

Using two enforcers (with reflectors) I have a prototype already made. The board inputs a signal from the two enforcers and outputs either a 1, 2 or 2,1 (depends on the direction of crossing the beams). I'd like to document and create a PCB sketch from it to eventually order multiple units of it.

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.

The project is to create a prototype for a wireless transmitter/receiver that works with Bluetooth Smart (low energy) and radio frequency signals. The device will need to receive instructions from a cell phone based app, and subsequently transmit a radio signal. It will also have to relay information regarding it's battery life to the cell phone based app. The Bluetooth signal must have high security. Ultimately, a reproducible design is needed for the design to be manufactured in production quantities.

Hello: Previously you responded to a request we published in Elance for estimators to perform quantity takeoffs. We were forced to place that request on hold due to projects being placed on hold. We are now preparing to commence work on some of those projects that were previously on hold. We are looking for some outsourced estimators who can perform both conceptual and detailed quantity takeoffs for these projects in all divisions. We especially need estimators that can do take offs on Mechanical, Electrical and Plumbing (M/E/P) systems. Experience with Planswift is a definite requirement in our selection criteria for Estimators. We need to utilize that program such that we can confirm the scope has been captured. Please reconfirm that you utilize Planswifth. If you are interested in providing estimating services to us at the rates you previously quoted, please send us your contact information (including E-Mail for sending project plans). Thank you.
