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...
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.
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?
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...
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...
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...
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.
The LM317 driver for led torch
i soldering power cable
This is laser driver but this driver two stages driver...
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...
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
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...
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..
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...
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...
