I'm looking for an electrical engineer to design the following: A circuit receives variable voltage from an SCR dimmer: (  [obscured]  /wiki/File:Lightdimmer_with_diode_bridge.svg) and passes it through to a load (a lightbulb). When the light bulb blows out, the device automatically switches the power to a backup light bulb.

I need an electrical engineer to help me design a PCB for a strain gauge indicator. I have most of the schematic already, but will also need some help connecting the already-designed circuit to the PIC18F, so some research may be in order if you don't know how to use the PIC18F. Attached is the schematic. Hope to hear from people soon and hope to get this done as soon as possible! :) Note: I will handle all the manufacturing myself.

We need to design a HV source up to 44KV of HV that feeds from a regular 120V AC source. Output signal will charge a ROD but no current will be used the rod is isolated. There are no requierements in power form and frecuency could be any frecuency as long as its a double polarity (positive and negative signal) The idea is design a small electronics/electrical transformer, very robust and weather proof. As small as posible it would work 24/7 ionizising the rod but just to charge it no current would flow.

Hello I am in need of someone to create all the files needed for me to produce a simple ion meter (mv meter, potentiometer) Here is an example.   [obscured]  /proddetail.asp?parent=12&prod=377&seq=3&TotRec=9   [obscured]  -china.com/enproductsview/604.html We need to make a much simpler cheaper version. We have made a much more complicated 6 channel ion meter in the past. So to that end, I have all the design files, we actually have 2 different models, so the basically all the details are worked out, all the components, values and schematics and so on. What I want to successful elancer to do, is use the data on the files for the multi-channel projects we have already done. Use the knowledge to re-create the drawings, gerbers BOM etc, so I can have a simple ion meter made. The ion meter needs to work exactly as we have made in the past in terms of the components and schematics layout, i.e we have worked out how to make the mV meter. It works by measuring ...

We need a low voltage indication pcb board to install in a lamp that runs off a rechargeable 18v battery. Ideally it would flicker the load (which is an LED bulb) occasionally at the warning level and shut off at a lower level. Ideally, contractor wold assist in finding a reputable manufacturer to produce the boards.

We are experimenting with the flow of a fluid through a device. The fluid is housed in the device and sealed with rubber diaphragms at either end.We are looking for an electro mechanical unit to oscillate the fluid through the device via stimulation of the diaphragms. The device has a volume of 500mL. The unit should use diaphragm A to send a pressure wave through the device. The unit should sense the pressure waves arrival at diaphragm B on the opposite end of the device. When the pressure waves arrival is sensed at diaphragm B the unit should use diaphragm B to create a return pressure wave. The unit can operate on just diaphragm A, or diaphragm A & B. The unit should be cost effective. See attachment for example of Diaphragm A only stimulation.

I'm designing a motion powered electric generator. I have come up with a way to generate the current, however I need help resolving the other electric components such as a rectifier or a capacitor that may be needed to turn the AC current to DC to charge a rechargeable battery. The power stored in the battery is to be used to light up an LED lamp. I'm designing this project in collaboration with and for communities that are off the grid. Thus the workings of the device need to be resolved keeping in mind that the manufacturing cost.
