I've been doing research into some home brewed add-on people have made for Arduino. I was surprised to find that there are a ton of custom shields that people have developed and sell right now (check this out: http://shieldlist.org/). This gave me some ideas for developing products myself. I'm trying to gauge what people are looking for in new Arduino product. If you could take a really quick survey that I designed to test the market, I'd really appreciate it? Here is a link to it: https://www.surveymonkey.com/s/PTSDD8Z Please let me know what you guys think would make great products for Arduino! On a related point, I was wondering about the feasibility of a brushless motor shield. I am working on an Arduino based dual rotor mulicopter with some friends (here is a link: https://www.youtube.com/channel/UC566tCzMbp-S5ThKuPQO_6g. We aren't too far in yet). I think for others that make "Arducopter", it would be nice to do away with external ESCs for controlling brushless motors. I think it would be far more convenient to have a shield that acts as a substitute for ESCs and also act as a power distribution platform for on board components. Is it dangerous to be running that much current on a PCB on top of an Arduino? Would it be wise to connect a 3S LiPo in parallel with the shield ESC and an Arduino, or could that damage my Arduino? Thanks in advice for the help!
