Re: Laser Barrels V2. GB. Second run. Kryton Groov Cool thanks :D

Re: Laser Barrels V2. GB. Second run. Kryton Groov You don't have to worry about anodizing I just want polished, this run was polished right? I'm actually thinking of trying to nickel /cobalt plate them

Re: Laser Barrels V2. GB. Second run. Kryton Groov Have these shipped out yet?

Re: Laser Barrels V2. GB. Second run. Kryton Groov Yup, that sounds good.

Re: Laser Barrels V2. GB. Second run. Kryton Groov Ah ok, I was thinking about trying to polish them anyway bare is fine for mine.

Re: Laser Barrels V2. GB. Second run. Kryton Groov You don't happen to still have a couple of black barrels left, or do I have to wait for the next batch?

Re: Laser Barrels V2. GB. Second run. Kryton Groov So everyone that still has orange by their name is waiting on the next batch?

Re: Laser Barrels V2. GB. Second run. Kryton Groov Replied to the email, no color though so I guess you haven't gotten my reply?

Re: Laser Barrels V2. GB. Second run. Kryton Groov That pd system is really sweet, I was thinking an adjustable power laser host would be cool, but that's an extra notch above that.

Yeah that's definitely a much nicer looking board. Solid state capacitor, diode to allow the capacitor to automatically discharge, pot that doesn't look like it will self destruct upon turning, resistors that actually fit between the through holes... The only thing that would be left on that...

Yep that's how I have it, I guess you didn't experience this odd only getting 1 ma out using the 100k resistor?

Hmm I just noticed that the way that kernelpanic drew the lm385 on his circuit is opposite the way the instructions say to orient it. Should it possibly be oriented the way kernelpanic drew it rather than the way instructions and the silk screening is? Looking at the side of the board with the...

I decided to build one more this time being very careful not to leave the iron anywhere too long, and double checking the lm385, but I'm getting the same results with the 100k diode. I measured 2.563v between the out and the adj on the TLV1117. I also measured 2.724v between the anode and...

Do laser diodes show any improvement from super cooling? Ie if you cooled it down to -30 or more would that give you any better results than around ambient?

Yeah I tried it that way too, it's just easier to adjust the potentiometer with it in series measuring since I can just use some clamps, not enough room to clamp onto the resistor. But I did double check the resistor and got the same values. Dunno why it's off by 100, but it seems to be...

I also tried running both the 2.7k and the 100k in parallel to see what I got, that ended up maxing out around 100ma The math though says that it ought to have been: 1/2700 + 1/100000 = 1/R, R = 2629 so (1.2 * 5000)/(2629 + 5000) + 0.05 = 836ma It seems like my circuit is off by a factor of...

Thanks! It was originally designed for the kes400a diode, which 62ma max would be a fairly decent max for. I replaced the potentiometer with a 5k potentiometer (since the one I had was broken) I was getting odd values of 1.1 to 0.9 ma or so once I did that with the 100k resistor in place...

Thanks, Kernelpanic, if you don't mind could you explain a little how you calculated the max current numbers? I tried assuming that the potentiometer was set at 0 ohms, and that 1.25v was going over the 2.7k or 100k resistor, but that should be 1.25/2700 = 0.46 ma, and 1.25/100000 = 0.0125 ma...

Since I have a few of these, but the potentiometer is rather crap, I'm trying to understand how this circuit works. Specifically how the resistors effect the ma. I understand how the DDL circuit works where you have just an LM317 voltage regulator, the regulator tries to keep a 1.25 VD between...

Re: PHR-803t GB 15$ #2 shipped I'd like one, let me know where/how to pay.
