  • Swapneel Datta 2016-05-27

    Hello. I’m an undergraduate electronics student in college and a maker. I’ve been making electronic projects ever since I was in fourth grade in school. I’ve been looking for a good reliable board for my next product - a high efficiency universal battery charger cum waveform generator, that would be cheap and with minimal external hardware, an all in one solution to power supply in the 0-24 volts range. I aim to unify the traditional switch mode power supplies and the currently existing function generators that colleges use for demonstration purposes, with a cheap and all in one solution so that even underprivileged colleges and even schools can afford one.
    My product would need to be microcontroller monitored, and this board seems just perfect for the application!

  • frankthatank02 2016-06-24

    Silego GreenPAK 5 Development Kit has to be the tool that helps me bridge multi system designs. One school class taught me FPGA by Xilinx and another PLC with Rockwell 5000. I need to see the big picture of Electrical Engineering with respect to all human needs via industrial, commercial, residential, medical, etc. Prototyping is the foundation of building a great product yet human necessity fuels and inspires us to create. I too am wheelchair bound and have difficulty with classes accommodating the labs and lab times so hands on practice is almost non-existent and thus hinders my learning. Autonomous robots now/ today with my recent injuries must be a part of my daily life and desire the tools to create these needed designs for the people from prosthetics to voice/ visual control applications of strong, hardy, durable products that are cost effective.

    Thank you

  • velizarw 2016-06-24
