hmm... do you suppose i need better heatsinking? Something more than the two DHs? Or should I skip out on the 420mA like the LPC is supposed to be able to handle? And just... turn down the power a bit?

My grandpa told me that he read an article in the new york times that talked about "holographic" hard drives. He said it could hold data that was burned into a 3d medium.... did anyone see this article? I want to know more about it... could mean more high power laser diodes on the rise. Maybe...

I'm using an LM317 ddl driver to supply about 405mA to my LPC-815. While I have the circuit running on a breadboard, I have the diode in an aixis module with two, DH dorcy original heatsinks around it. After about 5 minutes of continous running, the module seems to get pretty warm, almost...

guys, wicked lasers will always be heftier in their prices since they advertise everywhere. They have banners like ours, they have commercials, and they provide lasers to use in large movie productions. The price is in the name, it like buying an ipod, instead of a zune. Ok, crappy analogy...

for a nice diy atx power supply with heavy current capacity: http://www.instructables.com/id/Convert-an-ATX-Power-Supply-Into-a-Regular-DC-Powe/

ya kinda like the facebook app. Where you can PM other members with the push of a button, where you can flick your finger up the screen to scroll through the topics, (General, Red, Green, Blu Ray and Violet, etc.) Where you can view say, the last ten posts on that particular thread in a nice and...

hahaha niceee.

What about programming? Anyone here know how to make ipod apps?

Perfect. That's exactly what I needed to know. Thank you much!

I'm just about to set the current level for my flexdrive v4. I do have the users manual read and I know which pins are input and which are output, but shouldn't there be a small capacitor somewhere on the board that needs to be shorted out before i connect my diode after testing? If so, where...

I'd still like one since it means i can carry the book around with me on my laptop.

Interesting. I don't recognize the 10 and .1uf caps in the current regulating schematic. It shan't be hard to add those two to the parts pile! Mica... doable. Variable current control... no go. This is all definitely helping. Thanks a lot everyone!

Calc? No way! Finally! A useful application for my last semester of math! :D Yes try an FTP folder. That way only users who found this post will have access to the password. I've had bad experiences with bit torrents...

naw i mean like an Iphone-ipod touch app. Just like I can download movie info on mine to get movie updates with my flixter app. Kinda like i can check facebook with a facebook app instead of loading the browser and webpage.... A mobile LPF site would be handy too since i could save a link to the...

I don't know about anyone else, but sometimes I'd like just pop up lpf on my ipod or cell phone sometimes just for a quick reference. What would it take to get a mobile version of this site going? If not, an ipod touch app would be pretty slick too.... :D How can we make this happen? Wouldn't...

haha sweet! Do you have the LD driver on the same pcb as the motors' circuit? Or do you have a flex drive hidden in the module? Either way.... very nice!!

I have to wonder though how this guy has been able to come up with such a wide range of sleds... maybe we can figure out how he gets them so we can bypass the middle man? What if hes getting them all from the U.S.? You have to at least wonder since his prices are sooo lowww. :-?

Ah so it sounds like drilling may not be such an issue then. I'll probably just make many 1/8" holes in some sort of a circular matrix for the fan to push the air through. Ya I would've shorted my circuit if you hadn't have said something! Thanks! That seems kinda goofy tho..... posistive? It...

Niceee. This is very quality advice thanks again! The 317 bolting sounds very doable... I suppose that the fan would best be mounted in the rear panel, away from the LD so the ICs can be properly cooled when near the rear end of the enclosure. So what about vents in the enclosure that the fan...

Thanks for the help guys! Ok so heatsinking to the chassis shouldn't be necessary then... about the small cpu fan, should i focus its airflow more around the LD module? Or around the LM317s?
