my first build (lab style phr)

[Tech_Junkie]

Yeah I'm not going to use batteries either.

Everything sounds great md. Cant wait to hold them in my hands.

I cant wait to machine them and supply u guys with them! Also ill prolly start making heatsinks if there is a demand for them

Ahhhhh k. gotcha then ya no problems. Alot of computer parts suppliers sell fan controlling modules and they control the fan rpm by changing the voltages and if i remember correctly anything over 3v and as high as 14v will run the fan

awesome!

This build is awesome! The phr diode will have a VERY long life

 

[mdjd07]

Thank you! I hope so

Thanks guys. All the lasers I have built have always used batteries for the power supply. Time for me to step up and expand.

9V supply to the fan will work it will run at a lower rpm but still sufficient for cooling, one thing, you may want to give the fan its own power it will drain a battery rather quick from my experience

will do. i was going to wire my fan right to my switch where my 9v goes to the driver. i am not sure if this would be a problem. the fan im using says : 12v dc / 0.13A / 1.56W / DC Brushless Fan.

Glad to help

I have a question: Could you make a hole for a power jack? It would also need a place to screw it in for mounting purposes, I'm using the sparkfun power jacks for the 5, 9 or 12V wall adapter. You could screw the negative terminal into the case and have it be case negative. This would work great for BRs and other case-negative diodes.

will

Is this what you are talking about?

I already have a 1/4'' hole in the back of mine, and was going to ask if I should put it in all of them.
I could make the hole any size
Heres a pic of mine

 

[mdjd07]

Also here is the pic I said I would show you of the change I am making to the box...The section of dashed lines will not be cut out like the origonal therfore serving as a heatsink. And where the star is will be a set screw to secure the axiz.

 

[ossumguywill]

No, I have this

and this

however, I now see that you might need a square hole or a hole big enough to fit the metal part AND the end of the plastic part so it can go all the way in to the power jack. Can anyone recommend a power jack designed to be stuck through a hole and tightened in (I hate glue)? preferably one that would work with the sparkfun wall adapters.

thanks,
will

 

[Tech_Junkie]

Grommets work well too. I'd leave the hole at what it is now.

 

[mdjd07]

Ill leave the 1/4'' hole, but if people need a different size hole that is not a problem at all.
No comments on the new design of the front of the box? Guess its good?

(I hate glue)

I hate glue too, but gorilla glue is amazing

A+ bro. Much better design.

 

[mdjd07]

Thanks! I thought so too, I guess I will just have to drill some holes in the side of the box for venting the fan?
