I know this has been convered and the 6X diodes are "old news", but I'm excited and besides I took a few nice pics which someone might find useful. I really took my time harvesting the diodes from this sled, determined not to have any disasters. It's a nice sled, love the PBS cubes, dichros and...

HAHAHAHA! You fooled me, I thought you were serious about that being your "girl". She's more manly than a lot of men I know. :crackup::crackup:

Hey Ray, nice to meet you. We need a few more "old timers" on the forum, based on results of a recent, "how old are we" thread. Judging by your nick we have the same taste in books. :tinfoil: Tell us what lasers and laser components you have.

Re: First Laser build and first red Good work with what you have at hand. Be careful driving it at 450mA! That's not exactly a safe current, looks like jayrob's copper module is giving you excellent heatsinking for it to survive that.

phototransistor would be an easy option I reckon, with a focusing lens infront of it depending on the size of the target you wanted. Like THIS

Posting mine again with the correct KRYTON logo this time:

Yes HIMNL9 - please have a look and tell me what you think.

If you look directly at the sun without eye protection how many mW of energy do you think your retina is assaulted with? I'd be curious to know... Answered my own question - according to wikipedia typical sunlight contains 120 watts of light energy per meter2. That's equates to 0.00012W/mm2...

By-passed the switch and it's still behaving badly. I now suspect that 1ohm resistor... I drove the driver with 11.4v and got a linear increase through the range... I think this testload is dropping the voltage more than it should be and we're running out of steam... I'll buy some different 1ohm...

hmmm. yes, that would make sense wouldn't it... I'll try that out tonight. Thanks Gryphon, I hope you're right.

My condolences electron. Time heals all wounds, look after yourself mate.

I was up late last night building myself a nice little test-load. As you know it's pretty simple stuff, put it all together with a switch to flick between 6x IN4001s and 4x IN4001s. I've got a nice convenient socket to plug the multi-meter leads into and aligator clips for hooking it up to the...

I grow LOTS of herbs too. Don't have time to list them now. Netwave - sounds very interesting! I may pm you soon to find out more. We might be able to do some trading. :yh: Here's a pic of my current edible garden - Not a lot growing right now, too cold and gloomy here.

Re: FS-IGORT build bluray 191mW Can we have a bit more info please? What model diode? What current is it set to?

I wouldn't worry too much, your most likely problem will be how to clean the greasy fingerprints off the window. :crackup:

Love my vegetable garden and we grow lots of different veg in the spring/summer/autumn. The winter here is a bit tough, but we've got onions, chard, fennel, radishes, bok choy, broccoli, celeriac, leeks and some broad beans going at the moment. Oh and a few peas in too, but not doing much at the...

36 this year, all year. Life just keeps getting better!

That's a very good photo especially considering your modus operandi! Very impressed. Yeah post more josh. I need to buy me some more green, it's being budgeted for as we speak.

Thanks AAlasers, I think I will grab a set and I'll write a bit more of a review when they arrive. However, not having a LPM it's hard to accurately assess these things. I can discuss the beam fidelity after passing through the dichros and estimate the losses; I'll do my best.

I noticed this set of 2 dichroic filters on o-like's website, only $29 for the pair. Anyone know if these are a quality product? I can't find them for anywhere near this price on other sites. RGB combining system I'm planning to start building my scanner with these, getting the optics together...
