Hi Red, Thanks for the info again. I plan this to be a permanent job, so with the correct and most efficient way and yes, also the safest. So my main question is. what would you propose I do and the components I use, battery etc and any more suggestions. The company I work for is quite...

Yea ignore that, I drew it wrong

Hi red, I've changed it now, that missed my eye! Can you check my latest post I replied to you with. I've put in a wiring drawing, and some questions that i hope you can answer. Cheers

Hi cyparagon, What I'm going to do is do a full check sheet of the data and see what spec everything is and will work at. Tbh red has answer most of my questions for me and shown me what I thought. I've done a lot of maths and I understand this stuff as I'm a qualified electrical engineer...

Hi Red, I've had some free time now and drawn up the wiring diagram for approval. My only remarks are.... The 08 Datasheet says the Absolute Max Current is 3.5. And with 3 x 1 ohm resistor = 3.75 its 0.25 over. what do you think? I don't want to blow these boys! 1.1 ohm would cover it. what do...

Hi Red & Sta, I've changed the name to 08, however I cannot find where to edit the title of this thread anywhere. cheers

Hi red, Thanks for the info: I will look at this all deeply tomorrow and make a wiring diagram and see if you approve of it. It's 11pm here and tomorrow I've got to crash test some cars! So I need my sleep. Speak to you and everyone tomorrow :) bye !

Hi Diachi, I was having a look at a power supply. Lithium kind was $40 and was 7.5V with 248A. What circuit arrangement would I need to get that to work then ? Cheers

Hi Red cheers! It would seem you knowledge is very valuable. Would it be possible if I could get this on a wiring diagram of your suggested idea as I feel this would be better ? Nothing special, just pen on paper and just make a circuit which is all clear for me. That would be great. I don't...

Nononono :) I am wiring the LD in series. But the lm317s in parallel. Do you follow ?

Iknow this, that's why I'm connecting them in series... Have a read of my thread please

Hi Diachi So why do I need the 7.4V when you mention its 2.5V. Can you explain this please and with the maths if possible. And cheers. Iknow they will be connected in parallel, as this is better for the amps

Hi DashApple, I'm aware of the drop out voltage. But what do you mean in CC mode ? If I had 4 LM317's would this be 1.25V x 4 to cover all 4 dropout voltage.

Hi red, I'm from England, so sorry if the meanings are different. What do you mean by 7.4V cells? Is that a 7.4V battery? if so, could you explain why I need a 7.4V battery when the LD works below. Series = 34V / 8 = 4.25V Mid And thanks for the different LM's I will look into them and see...

Hi red. Did he wire to the LD's in series or parallel? From the maths in my thread I know that they will be parallel. It just depends on how many lm317s you have due to the power supply output

Hi all, Yes I've had a few lasers made before, just something like the one is a bit different. If you could answer my questions within the thread that would be good. And if you do, can you explain why please. Going to be making this project this weekend. I've done all the maths now and...

Hello everyone, I welcome myself to this great forum and hope you guys can help me with my current situation :thanks: I’m going to categorize this into A) B) C) Recently just bought a 08 Laser Array and need to know how to get this boy working! I will run you through my maths and hopefully...
