Looking for an experienced electrical expert to help develop a device that can connect to a chip which will eventually make noise(in form of music sound) either through a radio waves, Bluetooth, WiFi or any reasonable and affordable wireless way to do it. Once this is agreed more can be negotiated as mass and details will be available.

We are producing a square waveform as an output form a raspberry pi. The wave is 0 volts (+-1v) when low and 3.3 volts when high. I need the high voltage stepped up to 16v +- 4v whilst keeping the (roughly) 0 volts at zero +- 4v. The output waveform needs to keep the square shape and the frequency will be about 2.5khz. I would need a parts list appropriate for a breadboard and ideally using part references from http://uk.farnell.com and a schematic for laying it out correctly (a photo of the complete board would be nice too).

I'm looking for a experienced electric / electronics specialist in UPS and batteries to help me to design an economic solution for backup 2 computers, 2 monitors, 2 pos, 2 printer, 1 pbx, 1 router, 1 switch, 5 access points, for at least 4 hours when commercial power was cut. It's not usual event, but it can happen once a month, so I would need that solution feeds with energy for at least 4 hours. I prefer someone who has experience, because you should take into account several parameters in ups, battery, etc like current float of battery, battery should never run out of energy, discharge curve of battery affected by temperature, etc I measured the circuit where all these loads are working with a current meter clamp. The total current measured were 2.5A / 221v and power factor around 0.8. Total power is around 442w I was thinking to use for this application : - VLRA or gel battery - Pure sine inverter charger http://www.aliexpress.com/item/INVERTER-24V-to-220V-230V-240V-Modified-Sine-Wave-Power-Inverter-DC-to-AC-3000w-6000/32456942300.html?spm=2114.01010208.3.2.lVOpmA Pure sine inverter charger has the function to conmute between commercial energy and battery energy. I would like to use the products that are available on market like the pure sine inverter if you have a better idea for this project, I would like to know your propose. Please, avoid copy and paste curriculum as your answer, I would like to know more about your propose about this project. Remember I can read your curriculum in your freelancer profile.

Hello I need to hire an Embedded system specialist who would help me to develop an application on Beaglebone. that would let me switch two RF signals. So far I have two CATV signal from different providers, but only one is connected to the CATV amplifier and when there is an issue with the CATV signal, I have to unplug the CATV cable from CATV amplifier, then I plug the another CATV cable to fix the issue meanwhile the CATV signal of the another CATV provider come back. I have a RF switch board that you can check its datasheet on the information I attached this post. Basically It should be feed with 5v between pins GND-Vdd. With pin Vctl you can control the RF switch when you change the voltage from 0 to 2v. You would help me developing the application that would let me switch from input RF1 signal and RF2 signal through a website, where I would have 2 options to select: Enable RF1 input or enable RF2 input. Besides, I would like to connect to beaglebone board a lcd display, where you would write the RF signal that is active in this moment. Finally, I would like to add a switch or something similar to switch from RF1 and RF2 input signal manually, just in case there is no network connection to beaglebone. I would switch RF signal manually. I've attached a picture of what I'm looking for. Please, avoid copy and paste curriculum as your answer, I would like to know more about your propose about this project. Remember I can read in detail your curriculum in your freelancer profile.
