New pen style blue-ray...Home brewed :)

[rog8811]

There is no particular seller, they just come up now and again. Here are some I have found......

You need to know that it is not just a case of taking the front off and pushing in the module.... you need to cut the external thread off the front and bore out the front end to fit the module. Then the module needs to be modified to have an isolated contact for the battery. Sketch below gives an idea of the setup in the module.

rog8811, WOW that is nice and small regulator cirt. How much mA and volts is it putting out with 2 3.6V batteries?  

 

[rog8811]

How much mA and volts is it putting out with 2 3.6V batteries

I set it to 40ma, voltage unknown as I didn't measure it but it will be less than 5v.

Picture below shows the dezombified output...along side a senkat red in the same host.

I have been asked by many people for prices for complete blue-rays, I am still waiting for the final price on the GB PS3 before I can quote that, due to popular demand I have been looking at the idea of making a kit of parts for the blue ray ( You could attempt the red with SMD as chido says) as follows.

Modified barrel with tail cap and clicky switch (it is not the nicest feeling clicky in the world but it does the job)
Aixiz module with isolator and battery contact button

You just need to add your LD, Circuit and a pair of TR10440 batteries from DX.

I could do it for $40 (£20) ...I would need to find out how much postage to the US would be though. Let me know if you are interested. If there is enough interest I will make a post in the buy sell trade section to formalise it all....

All I need now is for the new Blue-ray GB to get under way and I will have 5 of these for sale.......... thats if anyone is interested of course

rog8811,

Will the Xbox diode work for you? I'm in the process of tyring to get some sled right now but I'm pretty new here and have no rep so a GB it out of the question. I'm trying to price 100 sleds so the cost will be about $23 to $25 each before shipping. This way I can just pay for it then sell them and not have people pay and wait.

 

[rog8811]

Are these sleds for the Xbox HD, that flogged has been working with? There is no doubt that they would do the trick in this barrel.... It looks as though some experimentation is required to find the ideal drive configuration for them.
I would be well impressed if you could get them for the sort of price you are suggesting.

I think I'm getting close, at least I got 10pcs at $28.65 each after shipping to test. I should get it in 7 to 10 working days he said.

I was looking at you part list and I think I can find every thing except for the resistor. Where did you find it and it is a 22 Ohm 1/4W right? Also do you know where I can find some 25 Ohm also? I was thinking of test is at a set 40mA, 35mA and in between with a pot. What do you think?

 

[rog8811]

Where did you find it and it is a 22 Ohm 1/4W right? Also do you know where I can find some 25 Ohm also?

Ther 22 ohm resistors were part of a multi value pack from ebay, as far as I know 25 ohm 1/4w is not a standard value.

I was thinking of test is at a set 40mA, 35mA and in between with a pot. What do you think?

If I were using that LD I would start at zero, work up to Lase point then go 10 ma more, same as the PS3's.....Run it long term at that then gradually up the anti.....until you find the zombie point

In other words you will be going into the breach for all future builders to discover what the safe, long term, values are for this LD. Good luck

ok i built the circuit from your schematic and it's really nice and small.
running a 360 hd dvd bluray diode using 2 cr123 batteries at 6V but when using a meter, it reads approx 8V.
what would be the optimal part list for that setup?
i took 2 years of electronics but i'm rusty on it since i rarely use the knowledge and all my notes and crap are at my parent's house.
i've heard 35mA is pushing these diodes pretty hard so 30-35 is what i'd probably be happy with if possible.

 

[rog8811]

what would be the optimal part list for that setup?

The optimal would be as follows
7805 regulator
100 ohm multiturn pot
10ohm resistor
10mf 16v capacitor
1n4001 diode
2 RCR123A batteries   (7.2v)

You will notice a couple of extra items in there....
The diode is for reverse voltage protection, rechargables give the extra 1.2v volts required to get enough overhead to keep the regulator working and the pot to fine tune it to lase point +10ma for a safe output.

That driver is superb! I got to try it sometime. I was thinking: is it possible to make a small and simple optical feedback circuit somehow, or has this question been asked already? I'm sorry if it's a stupid question  :-[. Maybe it's not needed at all... Either way, I think it's a nice and simple driver.

Excellent pen style lasers btw, 5/5. Good work!

 

[enkryptik]

wow thank you so so much. this is a really nice driver and totally satisfied with it. gotta go to frys to grab a few parts today

 

[rog8811]

@ FML

I'm sorry if it's a stupid question

Not at all, I have seen in the past a couple of threads about optical feedback, usually it is someone wanting to disable it. I know that users have found that the pin you expect to run the opto diode, on LD's like the stontek reds, turns out to have nothing connected too it.
I don't know if you would gain anything by using feedback on low mw LD's, as they do not heat up much and therefore the current doesn't change significantly.

[enkryptik]

don't have to use the diode do i?

 

[rog8811]

don't have to use the diode do i?

I just put it in as an optimal item, it will protect the LD should the batteries be inserted the wrong way round, I didn't fit one as I didn't have the room in the module

Regards rog8811

 

[enkryptik]

heh k cuz i was running out of room and i still need to put in the 10ohm resistor when i know where it goes.
