Okay guys, I did this before I left for work this morning, as soon as my Diode arrived in the mail. The video should speak for itself.

Much power, fantastic laser :beer: :drool:

To frying mosquitoes on the fly ahahaha

It would be interesting to know the actual current draw, not the estimated current draw with the test load. Either way, cool :cool:

Yes, it would help to know how efficient it is, by knowing the current it's taking to get to that power.

Nice laser, but very doubtful that it is only 1.1 Amps to the diode to get 1.6 Watts!

Most likely, the driver is being by-passed by accident or something to that effect...

What lens?

I forgot to mention that I have measured up to 1300mW with a driver set at 1.1A, but it is highly dependent on temperature.

aixiz 405/445.

How do I get current draw?

Test load should show what current is being put into the laser right? On all my jibdrives I have had, and I've built 3 or 4 guidesmans with them, with the driver unsinked, I have always gotten 1.1-1.3W

Was just wondering why I was getting 1.7W, when the driver can't be doing more than 1.3A according to jib, unless it is heatsinked

Try putting your DMM set to Amps in series with batteries..
I believe Jib's drivers are linear Drivers and not Boost..
That test will give you a very close current draw at the LD..

Jake is this the setup you were having trouble with that you sent to DTR?

No, it was the diode, and I blew that one to smithereens. I think the driver when I had it heatsinked touch the host and blew up, both driver and diode were lost that day.

This is a brand new diode I got from jordan in the mail today, and another jib 1.3A driver

Yeah, I know and said that. It has NO heatsinking whatsoever, unless you call a piece of electrical tape heatsinking

I had one doing this with a 405-G-1 lens (and fully charged batteries), but the driver was heat sinked

I neglected to check the current draw :yabbem:

Peace,
dave

I just checked the current draw, 1.42A, no driver heatsinking, and a 405/445 glass lens. I would like to run this baby at 1.8A, but I'm very satisfied with what it's making at 1.4A.

I was planning on selling this, now I think I'll wait and swap out the diode when I get another!
