Currently, the LEDroid power supply needs to supply the following:\n* 0-40 Volts @ 150 Ma Power to the LED array.\n* [[12 Volt @ 200 Ma for fan cooling|12voltCooling]] \n* 5 Volts @ 100 Ma for Arduino Control\n\nWith the arrival of the FETs - any FETs, we are going to do th [[40 volt test|http://docbox.flint.com/~flint/ledroid/40v_20150514_072910.jpg]].\n\nThe subsequent current design is to use the [[Berserker Power Supply |http://docbox.flint.com/~flint/ledroid/berserker_20150514_072910.jpg]] with an [[Arduino powered PWM module|http://docbox.flint.com/~flint/ledroid/2015-05-13_556_berserker_bb.jpg]] . This will operate either in single or two stage PWM mode.
The 12 Volt Cooling Power Supply component as of 2015-05-12 is as follows:\n\n* Low Voltage Consolidation with 3 7812's [[Picture|http://docbox.flint.com/~flint/ledroid/20150512_094308.jpg]]\n* Consolidated within the 40 Volt Power System [[Diagram|http://docbox.flint.com/~flint/ledroid/2015-05-13_556_PWM_bb.jpg]]\n* [[PC Power Supply|PCsupply]]\n

26 May 2015\nToday's diagrams:\n\n* [[Beast Light Pix|http://docbox.flint.com/~flint/ledroid/beast_20150526_073012.png]]\n* [[Berserker Beast Wiring Diagram |http://docbox.flint.com/~flint/ledroid/2015-05-26_555_4bb_bb.png]]\n* [[Berserker Beast Fritzing File|http://docbox.flint.com/~flint/ledroid/2015-05-26_555_4bb.fzz]]\n\nThis morning I built a 4 hi version of the light:\n\n http://docbox.flint.com/~flint/ledroid/beast_20150526_073012.png\n\n...and while this solves the problem, I am only driving the series array\nwith 125 Volts at 0.06 Amps through the FET. The FET is very cool and\nhappy and the 555 dims this very nicely with no flicker. If I short the\nFET Source to Drain, the current goes up a factor of 5 to 0.35 Amps, and\nthe LED array gains about 10 volts to operate at 135 volts.\n\nWeirdly enough the 4 hi LED array (nicknamed "The Beast") even at this\nme-Ger current level is really quite bright, and very dim-Mable with the PWM\ncontrol. Needless to say, I am casting about for a way to get the FET to\ngive me the extra 10 Volts and say north of 200 ma.\n\nThe design combination of the Berserker Power Supply and the Beast LED\narray is a hard one to beat from a value engineering standpoint.\n\nhttp://docbox.flint.com/~flint/ledroid/fet_opto_bb_2015-05-26_bb.png\n\nI am currently (no pun intended) rebuilding the system on a smaller\nbreadboard which will allow me to mount the entire beast to a heat sink.\n \nhttp://docbox.flint.com/~flint/ledroid/2015-05-26_555_4bb_bb.png\n \nI have done some research on "Buck Converters":\n\nhttp://en.wikipedia.org/wiki/Buck_converter\n\nNote if worse comes to worse I will add a relay to short the FET source-to-drain for \nthe really high power.\n\n27 May 2015\n* Changing FET resistor to 33k gives 10 v p-p at gate and full non-flickering range. See [[photo |http://docbox.flint.com/~flint/ledroid/bbb_20150527_112040.jpg]]\n* This will be turned into a brass board for production next.\n

Got 4 of these [[low voltage boost converters|http://mklec.com/modules/power-modules/voltage-current-regulators/oskj-150w-boost-converter]] maybe one idea is to modify these...\n\n\nFor the Butterfly Capacitor, I need [[P Channel FETs|]].\n[img[http://image.shutterstock.com/display_pic_with_logo/9/9/61386544.jpg]]\n
