An Active Power Filter is needed to remove harmonics in the current and voltage from the supplied mains power. The working is measuring the distortion in current and voltage and eliminate those by feedback that signal in the opposite way. Myself I am a technical engineer but would like a assistant to help me with it and a programmer to program the small microprocessor need to calculate the signals. I think the dsPIC chips from Micro Chip can be used for this. (dsPIC33EPXXGS50X FAMILY) I added a thesis pdf file in were the principle is explained. If have more questions or remarks, let me know

We are paying for written application notes based on Silego’s configurable mixed-signal ICs. These parts are very versatile so there are many applications that they can be designed for. The application note should be a 1000-3500 word technical white paper describing an application and how it uses the SIlego part. Writer will be responsible for generating the content as well as writing the app note. · 1k-1.5k word manuscript + 2 figures: $750 · 2k-3.5k word manuscript + 3 figures: $1,500 We have many topics that we can suggest for this or you can suggest your own for approval. Examples of topics include: Using GreenPak to generate a strain gauge, using GreenPak to create a salinity sensor, creating synchronous state machine with the Asynchronous state machine block in GPAK. Here are some examples of app notes that were done in the past: http://www.silego.com/softdoc/app_notes.html Please let me know if this is something you would be interested in doing.

My (cut down) Arduino seems to restart under heavy load - as in lighting an LED strip consuming 1~2 amps. It works fine with lower loads. I need an expert to look at it and advise me what could be wrong? No time wasters needed! If you have the skills and worked on something similar before, then please send me the following: 1. Your mobile number with country code and all 2. Similar project you have worked on Work will only be considered complete when your proposed solution works.

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).
