QUOTE(dchew @ Nov 8 2008, 11:36 PM) ok, but its hard to find led blub in kuching, any1 can tell me where to find the white n blue 1? i saw 1 shop selling white 1 for RM3 per bulb, dam exp.. haha.. then i think wan 2 export LED from here to kuching there.. wan do business v me? be partners.. lolz..^^ btw... is there any ideas on how 2 make the LEDs in a line? there means i put 1 line on top the interior of the case... any pics? Added on November 9, 2008, 2:27 am QUOTE(Aquariusdenz @ Nov 7 2008, 10:52 PM) normally is 3 volts LED... but i think you can get different LED with diff volts... so wat is rating of he resistor u used?EDIT: i ever tried connecting 3 LED's and stick under my CRT (looks cool but stupid idea  ).... i used resistor for each LED and i chose the 5V molex power.. my LED works well and didnt burn at all..  just to get suitable resistor if you use 12V...u connect it in series of paralle?

QUOTE(Aquariusdenz @ Nov 10 2008, 09:59 PM) i forgot which resistor i used for the LED but i know that im connecting it using parallel circuit... i've tested another set of LED which i didn't add in the resistor but connect in series to the 12v power... its 4 LED's in a row... as what we learnt in physic, voltage divide in series circuit so 12v divide by 4 LED's, each LED gets 3v of current... i've tested this and my LED does not burn after i used for half years... so the 12 v power is from PSU? or from other source? coz after i think... the PSU will get overload if i put 25 leds... will it blow?Added on November 16, 2008, 4:13 am QUOTE(meons @ Nov 10 2008, 04:57 AM) huhu wan do it but can it use at casing maa sure.. y not? after i done it up.. i post some pic let u see.. haha...Added on November 16, 2008, 4:17 am QUOTE(dchew @ Nov 14 2008, 10:05 AM) ok to make it simple, i found this guide on the internet and might help every1 regarding LED questions good guide... will sort of following them.. heheThis post has been edited by davidhomestudio: Nov 16 2008, 04:17 AM |
