    my first project "The Turk"

    Merhabalar... Umarım Türkçe yazdığım için yanlış yorumlanmaz çünkü yazacaklarımı ingilizce yazabilmek için çok uğraşıyorum burada Türk birine denk gelmek çok güzel lazerler hakkında çok bilgi aradım ama bulamadım burası benim için iyi bir kaynak oldu. Siz nerden katılıyorsunuz Türkiye'de...

    constant current driver

    THE AMC 7135 chip is very simple build a laser circuit with one cell li-po battery. So .. The other question? What could be alternative chip or electronic parts for constant current driver ? i will maybe found an other chip/electronic part in Turkey.

    constant current driver

    i am sorry my language is not good. :( if i try use a only one lithium battery LM 317 ? What is it minimum supply voltage LM317 constant current driver ? is it suitable use a only one lithium battery ? Do you anybody test it?

    constant current driver

    Thank you very much. i want build diy this driver . i need a schematic. i was build a project this link. --> http://laserpointerforums.com/f50/my-first-project-turk-88596.html but i use a 2 battery this project. Now i build a new laser with lpc826. i think use only one battery. if i use LM317...

    constant current driver

    Hi all i have a question. i have a LPC 826 and 1 cell lithium battery 3.7 volt 4000 ma. This question is ; how i drive LPC 826 with only one lithium battery ? thank you ...

    my first project "The Turk"

    Thank you very much for all comment. Yes it is include a flashlight and laser. And it is not teflon it is a Plexiglas. plexiglas like glass but not glass. Plexiglas is Poly(methyl methacrylate) (PMMA) is a transparent thermoplastic, often used as a lightweight or shatter-resistant...

    my first project "The Turk"

    be continued i was solder all cable and it redy to test.. i hold it cover.. i was test run first time.. the current 135 ma now.. i was test run first time.. the current 400 ma now.. you can see a beam i say a one more thing .. i was register here and i was read too...

    my first project "The Turk"

    Hi again me.. i add a moore pictures .. The host.. But the laser two function include. Laser & torch. i was use a 1 watt led lamp. you can see the picture. Devam.. The LM317 driver for led torch i soldering power cable This is laser driver but this driver two stages driver...

    my first project "The Turk"

    Now i will add a pictures and explane how i build .. The first LPC 826 diode Diode and axiz housing More electronics parts i was soldering diode and isolate cupper wire you can see And this is a aluminium cooler. block aluminium drill and cut left side.. i hold axiz modul...

    my first project "The Turk"

    Hi all i am again :D :) :thinking: yes i know i am ask a many question.. But not now.. i have not a question. i was build my first project "The Turk". i have a 90 pictures for this project. i sellect only 23 pic and i will upload now here. i was use this LPC 826 diode LM317 driver...

    LPC 826 driver with LM317 circuit

    Thank you very much for your answer. i have a 4 piece 1n4001 diode. put it serial and connect to my driver. But i don't use a 1 ohm resistor. Because i have a multimeter and the multimeter include a ampermeter. i was build circuit. i don't successful.. the 4 piece diodes very hot and the current...

    LPC 826 questions ( voltage and amps )

    Thank you very much. i search a heatsink. maybe take a cupper heat sink but now only test it. i do not run long time .. maybe 10 seconds.. this video is first test run.. But sorry i was talk Turkish language.. Maybe the second i will talk english..

    LPC 826 questions ( voltage and amps )

    i give my diode today. i test it run now. i use LPC826 and axiz. the driver LM317 constant current mode. i use 3.4 ohm resistor but the supply voltage for diode is high then 2.2 volt. i measure 2.8 volt and the current is 420 ma 0.42 Amp. is it problem ?? is this voltage will kill my diode in...

    LPC 826 driver with LM317 circuit

    i am change current resistor increase 9.5 ohm and then the diode voltage down to 2.2 volt. ok but the current down 160 ma. i have a power loss.. Please give me a idea for this operation? Help please.. i calculate the power. is it right ? 2.2 volt and 0.16 amp. Power = V x I ---> Power = 2.2 x...
