9v batt nalang ang gamitin mo gamitan mo ng 7805 o kya naman zener nalang.
Isa lng kc 9v batt q dito eh. Tpos antagal pa icharge Mas maganda kung AA batt lng ung supply.. Hehe |

I think katulad lang sya nung mga single cell LED driver.

pre try nyu muna aralin yung SMPS o "switch mode power supply", dyan nyu malaman kung paanu gumana yan.

ngayon ko lang nabasa ito, meron ako nyan naFREE ko sa cp unit ko nung namili ako ginawa kong led flashlight!  hehehe saktong sakto yung led sa butas  mabilis maubos ang charge ng battery kapag walang load sa output, yung load kasi ang nagpapaoscillate sa boost converter, naidiagram ko na ito sa papel di ko lang mahanap yung papel na pinagsulatan ko |

cd = candelas, measure ng liwanag ng ilaw.  self oscillating boost ba 'yung circuit? |

Mxado kc maliit ung label e Nkalagay sa manual tanggalin ung batt kpag wlng l0ad. Ung saken naiwan q ung batt.. Pgbalik q mainit xa. |

nge. sana ginawa niyang normally OFF 'yung transistor kapag 'di nag-oscillate. makakasira ng baterya 'yan at pwedeng mag-cause ng sunog.

oo nga, but it can be designed to either turn OFF or continue to oscillate para 'di shorted 'yung battery. dummy load or bleeder resistor pwede na. good engineers always think of what the end users will most probably do that the designers will never do. it separates men from the boys. |
