One LED light in the bedroom on 230 V, Color LED strips in the living room window pane with my own color controller, controlled from a PC: http://panteltje.com/panteltje/pic/ethernet_color_pic/index.html and none make a noise, and all of that comes 'on' the moment you switch it on, the LED strips can be modulated by music in color and amplitude. You can get 230 V LEDs here at the supermarket, they are getting cheaper too, some have a remote control I think for 'on' 'off' and color, and have labels indicating power consumption and light output.>What do you think the odds are that >FINsix will make it to 2015?Well the CV of some of those great people may mention they worked on the most advanced power technology ever invented and patented by MIT <insert professor name>, when presented on the *next* website. Last night I did read up on PC ATX power supply efficiency, the current 'best of the crop', and that is something like 93% (for 400 W at full load and 50 % power level). http://www.plugloadsolutions.com/80PlusPowerSupplies.aspx click on 'what is 80 PLUS certified" To be better they will at least need 95 % in their converters. At 60 W 5 % is 3 W, and 3 W in that small housing they have will get bleeding hot. So 98 % would be better, but it looks like they still use a diode bridge, still need mains isolation, absolutely need mains RF filtering, and output filtering (inductors!), so and those things have losses too. And the 230 V version. ebay is full with LED and laser diode drivers.... small PCBs.... As they say, waiting for their products, do not hold your breath.

Furthermore, the = >>overall reduction in component count, specifically of through-hole componen= >>ts, means fewer points of failure.It is not that surface mount makes the thing more resistant to vibration and shock. In fact the slightest bending of a surface mount board will cause disaster, the old resistors and caps with wires through holes would keep working when the board bended. It was an old mil requirement that wires had to be through holes in pins and folded around those some times and then soldered.... Not sure that still goes.

If you can keep your device secret, keep it secret. That costs nothing, needs no paperwork, has no fees, and never expires. But, that doesn't work if you're selling something with a clever circuit that anyone can take apart and understand.> RCA profited mightily from its guerrilla hold on radio patents.

IIRC, patent damages would still be collectable on the pre-expiration period of infringement even after the patent expired. Cheers, James Arthur
