Been making a 445nM laser.. when done I am hoping for 1000-1200mW of power..

For today a low powered test with no heatsink, running fairly cool, and probably 150-200mW.

The beam and its reflections are indeed blue, but my camera probably oversaturates and makes it appear purple.

Yup, bit of cameras make it purple instead of blue because of how bright it is. Just as you know use these with care, as they are extreamly dangerous. I'm looking to buy my third one soon for CNC use, since I have a 700mw Arctic and 1200mw 18650 CREED

I installed my Photo Gallery on my new Website, and I'm adding a few things every day so far and I think I still have another drive full of images not seen by anyone other than me yet, including some project stuff and art

The tektronix scope is broken but I got it dirt cheap and hope its just something simpel that i can fix. Not sure what the Interrogator set is suposed to do, interrogate people ??
Just bought it for the guts though as I have no plans to interrogate anybody cheesey

Looks like a nice find GluD!

Pics discharging 120J into foil with exposure. Bank can handle a total of 780J. I thought it was cool how you could see a rainbow-type effect in the aluminum dust around the trails.

No logging today, the old Ferguson apparently wanted a day off. I was barely out of the garage before a steering joint snapped. No big deal perhaps, but if it had snapped while at speed it could have ended in a disaster. The surface of the severed bolt had some rust on it, which implies that this was an old crack that had grown over time.

Looking a little cross-eyed there, grampa?

While i'm in this thread, i'll post two pictures from my spare time job, unloading grain boats at the harbour. I used to have a ton of great pictures from there, but after annoyingly formating the wrong memory card im down to just these two:

Now running around a watt
(4.25V, 1250mA)

I just love the patterns it makes on my walls when plastic melts.
but the camera just fails to do it any justice, in reality its about two times brighter, and the entire room glows blue from the dot.

Those thyristor module's isolated baseplates make good bussbars for caps... not to mention its also a switch at the same time!

Nice idea! Shame it doesn't work with my IGBT, my screws are too short and the mounting holes too deep. sad

You bet!

Although I wouldn't want to try this with anything higher the 24V or so.... wouldn't trust it.
but it works! (isolated devices)
