:beer: forever :beer: , last night i was awake and let the laser on the entire night, max temperature was 38,56°C or 101.41ºF on a run time of 7 hour's =) thank you for the apreciation =) soon i will post a video of the cnc working out some MDF

well then once i make the video of the CNC working then i will post it here =) thank you :beer:

so here i am, building my first very powerfull laser :drool: i brought the M140 diode mounted on copper module from DTR some LM317T from ebay (paid 1.20€ piece :gun: ) some great 1ohm 3W resistor on ebay peltier cell 90W 12V 6A on ebay ( no more used because useless since wen the laser goes...

Hi, your reply, gets a +1rep :gj: from me,this info make me think about a experiment i can make,:rolleyes: since only 34,03g are alluminium,and the rest of the electrolitic iron is about 146g maybe using a dallas termometer attached to the alluminium part can give me the right feedback on...

:bowdown: i am so sorry, now finaly i get it, the profile picture i put is in memory of my lpc-826 open can laser diode ( my very very first build and laser), since i have to go out now have litle time, but wen come back i will change it, excuses i didint mean to offend or "steal someone's...

i realy dont know, :thinking: at the bigining i was thinking about a "stupid joke" then wen i see that the thing goes on, i left them without replying enymore, btw, can someone please tell me if the improvised heatsink can handle at least 800mW of power? ps. you are talking about me for the...

@greenlander tank you, for the patience, i still need to read a lot on this forum, to knowlege who is who :D te opinion of you guys is precious,because you like other old members of LPF have much more experience than me on lasers, btw the holder is dumbed allready ;) waiting to come at home...

thank you, for your reply, and for the right holder,but i forgot to mention that in that holder i was thinking to fill the gap whit termal epoxy, is it still worthless the idea even using active cooling? ho is Blord? edit: i was not looking on a mA to mW chart but a post made by DTR were there...

Hi to everybody, first of all i have to thank you guys for the good work providing information on any level for lasers ,and since my first baby died by excess heat after some (?12/15?) hours of continues operation (i forgot it on :yabbem: ) now i am thinking to take one of tose great 445 M140...

:) hi there Cyparagon, maybe you are right, my idea was only pure logic seeyng the photo of the LM317,if you notice there is a treathed tube on the right, so i was thinking about the laser being mounted and that air inside the tube (spacing betwen laser diode module and heatsink of LM317) due...

not to be rude, but i have the LPC-826 LD from odicforce's ebay shop and use it continuesly for around 15 minutes at 2 different current level, first one at 330mA and the second one at 610mA (i have video proof about this) ,it is true that it became very hot (the aixis module) in the first...

:eek: That heatsink is too small (the one on the LM317) the LM317 can handle on its own only 0.25W of power but whit proper heatsink can go up high to 1.5A (heavy duty 3x3x4cm heatsink and overflow of air forced by a cooling fan). the LM317 IC has an internal shutdown sistem that is trigered...

thank you, i fixed the links in my quotes,if you cannot view just copy and paste in the browser the playn text cant wait for you reply on what you think about the laser once you see the video. peace :friend:

Hi, first of all, please excuse my very bad english grammar, i do speach better than i write :o however, it is a long time since i viewed this forum and a lot i learnd from you guys on lasers and for this i can only say :thanks: . since i was building my first laser and driver, i say'd to myself...
