micro-air easy start

I've several times criticized micro-air's claims but I'm going to back them up on the "slowly raising the voltage" statement. I'll place my bets that they're using a microprocessor controlled thyristor for the hardware. There's no need to keep that a secret as it's not rocket science and commonly used. For somebody who knows how AC speed controls work, it's obvious and there's no need to say it. For others, an explanation would just be a tutorial of something that's pretty common. The "magic" is the algorithm in the microcontroller that determines how to ramp the peak and RMS voltages. That's a trade secret that they will be tight-lipped about. What makes or breaks their product isn't so much in how it works, but in the time and effort of designing and perfecting the control algorithm. Here's an application note for hardware that could be used for what the micro-air does:

Sure I could be wrong. Based on the size, price, and description of the micro-air, it just looks like it's a thyristor device.
