An excellent topic on how to deal with SPAM. Is something wrong with StackOverflow's spam filter? Recently there have been huge numbers of spam topics related to football streaming. They have all been spam flagged and deleted but there are more getting posted all the time, I just flagged another 6 or so a few minutes ago. This has been going on for around 3 days now with these topics getting constantly posted over and over again in the

I have a project that uses an ESC to run a brushless motor (Hobbyist RC plane sized, 24 gram, 1300-1500 KV). I would like to experiment with eliminating the ESC and driving the motor with my own circuitry and control software. Are there any good tutorials or other starting points?

I'm designing an ESC with a small microcontroller running at 3.3V. The BLDC motors I have chosen are extremely small, and run best at 3.7V. I have the power supply for both of these (3.7V is VBATT, 3.3V is obtained using a buck converter). They are 3 phase, and the controller needs to be sensorless. I would like to measure RPM and current usage as well if it doesn't mean I will have an overly complicated design. All the docs I have found are great for higher voltages, and ridiculous currents (I will max out at ~5Amps at 3.7V, I don't necessarily need to design a 100V, 300A ESC). Questions I have: Is there a reference design I can follow somewhere around the net? What kind of protection circuitry should I use? How simple can I go? Are there any ICs that will simplify the circuit even further? Any other recommendations/tips/pointers?
