    Hi All, I'm looking for some help designing a few small PCB layouts. My end goal is to have 4 independent wireless MEMS accelerometer boards that transmit data to a micro-controller board. The micro-controller also will have a bluetooth module so data can be output to a cell phone or laptop. The 3-axis accelerometers will be sampled somewhere in the frequency range of 1-2kHz (to accurately measure vibration). I should note that, as a mechanical engineer, I have minimal ...

    We are looking for a contractor to help us with simulations for a PCB antenna. HANDS ON EXPERIENCE WITH IE3D IS A MUST. The work includes the following steps: 1. Antenna simulation for free space (Base Design) -- simulate the return loss and radiation pattern and prove that the simulation is consistent with the reference design. DELIVERABLE 1: Charts, graphs, etc showing that the simulation for the Basic Design is consistent with the reference design from the manufacturer and provide the ...

    Looking for some assistance in the design of a Class B power amplifier. This is the final stage in a servo system. The power amplifier drives a motor whose coil resistance is typically less than 2 ohms and around 100 microhenry. The power amplifier is supplied typically with + and - 24V. It works but needs some tuning. So we're looking for someone with circuit simulation experience, and with experience optimizing power amplifier output stages.

    So I have a concept project I am working on. A small electronic device that I could really use some help with. I have some designs done in Proteus, and Gerber files, but its not yet completed. So I need someone willing to start from scratch and deliver gerber files. In short, the design has a 16 pin pcb connector, which pulls 12v dc power, outputs sound, outputs 5v usb charging power, not reading capabilities, to 2 usb females, and ...

    My original design is not yet complete. I want to change a few things on this design, and have a few things added. 1. Pad size changed from 60 to 125mm. 2. A cooling unit of some sort. Would like recommendations on this after you look at the design. 3. Add a pcb bluetooth module that outputs audio and phone calls from a cell phone or tablet. This would need to also have a small button to turn the bluetooth ...

    200 Amp On/Off Switch I am in need of creating a nice on and off switch for a project that I am working on. I need someone who already has existing experiencing working with this type of work. I would like to make an electrical switch that can handle 200 amps of current for an electric vehicle that I am using. I want to be able to mount a switch similar to this item here - http://www.ebay.com ...

    I'm exploring a new project that will require the development of a passive rfid tag capable of being read over a distance of between 5cm and 100cm by a mobile phone. The tag will be used in clothing and so needs to be water proof / heat resistant and wearable. I have found a tag by Fugitsu which looks ideal but I need the tag to be readable by a mobile phone not an independent tag reader (Fuji tag datasheet ...
