PHR-803T blu-ray laser diode in AixiZ housing powered by rkcstr's Micro-Drive

[TheBeeman7]

I got that same laser module but it wont unscrew or open to put in a 405nm 150 mw diode Please help did that module come with a 650nm 5mw diode because is so i think thats the one i have

[happyguy82]

@TheBeeman7 The diodes have to be pushed out with considerable force and the same can be said about the installation process. I've got a few spare AixiZ modules with the 5mw diode built in that will require removal. I'm happy to post these to you for free if you would like them.

[TheBeeman7]

@happyguy82 i know how to get them out but it won't unscrew to let me get to that point where i can get them out

[happyguy82]

@TheBeeman7 ok I can only guess that your module is stuck, overtightened or the previous person has applied some kind of threadlock glue before screwing the both parts together.

[TheBeeman7]

@happyguy82 thanks any way

[happyguy82]

@TheBeeman7 Just to clarify, there are 3 parts to the module. The body itself unscrews at 1/3 from the top and the lens also unscrews off the top. As before I am happy to send mine which unscrews ok.

its 3 not tree THUMBS UP IF THIS PISSED YOU OFF

[jeroen207]

I have what question of your project, Did you solder the laser in the housing? and how much volt does it need?

[link1478]

eight zerho tree tee laser diodah

[unicyclst]

Did you honestly solder directly to lithium batteries?

[happyguy82]

@unicyclst yes but I'm aware of the risks and how to mitigate them. :)

[skimowhite586]

@happyguy82 how many mW does it have

[happyguy82]

@skimowhite586 eerrrr I can't remember precisely to be honest but what what I recall, these blu-ray lasers have a lower mw power output than the red ones. I believe it was 170mw or perhaps it was as low as 120mw. In any case, they are sufficiently powerful for melting black plastic.

@happyguy82 dude great vid hahaha how u make it less severe soldiern

[grassul88]

Your English - shit, man!

[mustbethebe]

@grassul88 what the matter ?

not everyone has to speak english!

[ImOnaBoatFool]

do u need a driver or can u use the one that come with the aixiz housing

[happyguy82]

@ImOnaBoatFool yes as the original one wouldn't be powerful enough.

[ImOnaBoatFool]

@happyguy82 i dont have a driver could i just use a capacitor if so then what kind

[happyguy82]

@ImOnaBoatFool no way, these diodes are so sensitive that you'll really need a PSU that regulates the voltage for you, otherwise you'll burn the diode out almost immediately.

[ImOnaBoatFool]

@happyguy82 even for a 16x red laser

[happyguy82]

@ImOnaBoatFool ohh yes definitely. any laser diode for that matter.

[iceCOLDkillaxDLoL]

@ImOnaBoatFool make an lm 317 driver

Finally!!! Someone who annunciates what he's saying and doesn't mumble. I understood everything this guy said and all the gadgets used. Totally freaking amazing for a youtube video! What's just as amazing, is his accent doesn't even sound local! Eat that, all you mumbo jumbos!.

[AJEET465]

can someone help me i want to make a burning laser but i dont know were to get the aixiz laser housing and do you even need it because isnt it just there to hold the laser diode in place.

[happyguy82]

@AJEET465 the AixiZ housing has a lens that focuses the laser. that's why you need it. search for aixiz laser housing on google

[AJEET465]

@happyguy82 so is it like the blue lens that comes up when you disasemble the dvd burner ?.

[happyguy82]

@AJEET465 no not really. the axixz lens can be turned to focus the laser, just like on a camera. it can focus the beam either to burn stuff or to shoot long distance.

[boxmour1]

it really pisses me off how u say three....THree not Tree gooool...dw ily

[tyler2260]

cool

[daniyal2008]

@happyguy....where did u get or find the laser housing?????? help!!

[PorkChopify]

How hard was it to calibrate the driver?

[ossumguywill]

@PorkChopify it's not. You set it to low current, attach it to a load (test load or an actual diode), hook up a DMM to the laser pins and set it to the desired mA. The max recommended for this diode is 120mA.

[iseeacircle]

isnt uranium like dangerous? or like cancerous or something xD

[happyguy82]

yeah but not in small quantities that's been turned into glass. furthermore I wasn't ingesting it :P

[ossumguywill]

@iseeacircle no. It's safe until you breathe it in.

[ZZAKON]

Can you please inform me if 200mW "blue ray" is stronger (burning power) than a 200mW red?

[happyguy82]

errmm nah.. Red would be more powerful. Basically Red shines much further, is A LOT brighter and easier to focus. I don't know why people make blu-ray lasers anyway. Just coz they look nice I guess.

[ossumguywill]

@happyguy82 not really. Red is more visible, but blu-ray is better for burning 99% of the time because things will absorb more near UV than red light.

[happyguy82]

ohh ok thanks. makes sense.

[ossumguywill]

yeah np it's confusing because red seems more powerful but really it's not.

[happyguy82]

I still find it hard to believe what you said tho... if you were referring to IR then yes I can appreciate. The power is there but our eyes can't pick it up hence we perceive it as dimmer but the power is the same.

In the case of UV laser like blu-ray, when we shine it on a white surface it should reflect back UV very well but it still seems dimmer than a Red would?

Why do materials absorb more near UV light than red? If it does that with IR then UV would be the total opposite right? thx.

[ossumguywill]

I once saw a cool graph, I forget where, that showed which colors we see best. Green light at around 555nm is the most visible to humans, while laser red is about 1/5 that much. We have evolved to see some colors better than others simply because they are more usefull. We see green because we need plants, red for fire or blood, and blue for water. (these are guesses) for some reason, we are the most sensitive to green. And almost everything is "black" to UV. Some things absorb almost everything.

[happyguy82]

thx

[boone473]

What current are you running the PHR at? Are you using the default Aixiz acrylic lens?

[happyguy82]

errm 96mA I think. yes standard Aixiz acrylic lens

[WhoTubeProductions]

What about the MicroFlexDrive V4?

[happyguy82]

FlexDrive V4 is a different driver. That's even smaller. That can run off a smaller sized battery because the FlexDrive is a boost/buck circuit which means it will drain more current from the battery to boost it's voltage.

[WhoTubeProductions]

Well, what driver will let me get a higher power laser without breaking the diode?

(sorry im a bit new to laser building)

[happyguy82]

something called a 'pulsed driver' because they pulse the output rather than put out a linear supply. however pulsed drivers are a lot more complex and expensive.

[WhoTubeProductions]

Can you reccomend the parts for a build with a pulsed driver?

and prrox cost?

This would be GREATLY appreciated, and if it all works out ill sub you. Ehh, ill just sub you anyway, i like your vids!

[happyguy82]

Hahaha no unfortunately pulsed drivers are out of my league :(

[ossumguywill]

@WhoTubeProductions dr. lava makes a TTL modulated driver. He also makes a step-up DC to DC driver called the flexdrive.

[WhoTubeProductions]

@ossumguywill Awesome thanks, I'll look into it.

[happyguy82]

Yes with this driver 'Micro Drive by rkcstr' it will work with a 9v battery. It will also work for red laser diodes. Reds use more current but lower voltage compared to Blu-Ray.

No heat sink. I only leave them on for 30 secs at a time so it's ok.

[UltraViolence14]

oh and will it work with a 9v battery ?

[UltraViolence14]

have you got a heat sink for that ? they get so hot
