The REAL Kryton GB round #3. Taking payments now.

No idea how you would run the batteries parallel in a tube. Still 1A is a lot of current for an un-heatsinked 317. Plus i was planning on buying a preset driver, because I cannot afford to blow a diode. Ugh, looks like a beast may be a no-go...

Who ever said the 317 wouldn't be heatsinked? The beast will have plenty of surface area inside to heatsink a driver.

Also, running batteries in parallel in a tube is fairly easy. It takes a couple pieces of rubber and two wires.

Whats so hard about setting the current on a driver? Its pretty impossible to mess up, especially with a 445.
 





Never said it was hard, just don't want to take the chance. As for 317 heatsinking, the inside of the beast is round I assume. T0-220's aren't exactly round.

Alright, I've had enough. I think I would have taken the square peg/round hole situation into consideration. I obviously can't tell you anything, the guy who can't even set a laser diode driver.

Trust me, it works.
 
You sure didn't tell me anything in that post. As I said before it's not that I can't set the driver, I've built robots for christ's sake. I'm just not a rich f#@k that can blow $50 diodes. :yabbmad:
 
Why don't you spend the money on a dummy load instead of a preset driver? Then you can be sure that the driver is set properly, or didn't get bumped slightly, etc. I'd never trust the pre-set value of the driver. The "hard" part about setting the driver yourself is soldering the jumpers on the driver, not the adjustment. You can save up for a $50 soldering station to do that with later too.

Spending money on the tools--including your own skills--not paying for services, is how you stay "rich."
 
I have a soldering station. I'm by far no stranger to electronics. My problem is figuring out what driver to use with 7.4V input. At one amp, an lm317 will get hot. I've also never trusted those linear regulators very much. When they fail they let the full voltage through from my experience with them.

What about the LM350? Good up to 3A!!

And for the LM317, you don't have to use the T0-220 heatsink, you could heatsink it with any shape aluminum or copper. People have even heatsinked these things with copper pennies with success.

From what I have seen the forward voltage is around 4.0V - 4.4V. But the most common FV I have seen people having with the 445nm diodes is around 4.3V - 4.4V

I believe the discrepancy comes from different batches or just the variance in how the diodes are made.

I'm currently setting up a lm350 driver for my Kryton Groove. The Beast has a larger driver chamber than the groove and the grooves more than big enough for a heatsinked driver in T0-220 size.
 
Yeah, I was going to suggest Uranium search, but I decided to just put the info down anyway.

From my own personal experience of 1 diode my FV was 4.4V, and I searched for others and in about a minute I found that is about what everyone else has for FV as well.

It is amazing what you can learn with the search tool on this site. :yh:

So true, :beer:

Man I wish I could get in on this GB!!! :yabbem: I won't have any $$ for another 3 weeks. Hopefully Ken will have some extras to sell me later? :whistle:

Hey Kevlar, don't worry :D ... Ken said he is going to have 100 grooves made and 30 Beasts made. IIRC (and I just checked) only 73 of the grooves are spoken for and 17 of the Beasts. I think within 3 weeks time not too many more will be taken and hopefully you will be able to own a piece of expertly machined aluminum from Kenom's Designs and LPF History!!!

I hope so, these things sell like hot cakes!!! And for good reason too. :bowdown:
