    Ive noticed that on twitter, links to rumble are shown as "unsafe". Such a desire to control what people watch. Regardless of these attempts to discredit and defame, rumble is picking up some serious traction in the last month or so. Whatever will the control freaks do when they lose control of...

    For those who enjoy long form podcasts, my recommendation for tonight is Dr. Kevin McCairn PhD in systems neuroscience. Now retired he has taken special interest in SARS and its long term damage.. Worth a watch if your only source of info on the virus and mRNA tech is mainstream. His guests are...

    G-Ball Adjustable Lens Adapter - Focus Fixed Lens Laser Diodes

    I too am curious of this. No mention on here or ebay. "1) % efficiency in light output"

    Brooks hit what, 70 people? including babies that couldnt walk, old ladies, and killed an 8yo kid in front of his brother. Showed not one iota of remorse, wasnt charged as a terrorist, nor with a hate crime. Very telling how the media and leftoids completely ignored what was behind the attack...

    Minimum power required for PCB etching?

    I etched boards for a few years but got lazy. Its a tedious endeavor. I got quite good at it, but hated the toner transfer part. Finding the right paper was a pain in the rump, Even tried the special made clear transparencies from the local electronics shop. Just such a pain lol Something as...

    Minimum power required for PCB etching?

    Damn, I knew that would have been too easy. Though at least one step can be skipped and that is the toner transfer by using black paint and engraving the layout then directly into the acid bath. Some neat systems out there, this guy showcases one with appealing results.

    Minimum power required for PCB etching?

    Forgot to add and will reserve this spot for pics; I bought a block of nubm08's where I plan to remove a row of 4 and use the remaining four in their mounts to knife edge and focus the combined to a fine point just deep enough to breach the copper layer on PCB clad. Would 20W be sufficient, or...

    Minimum power required for PCB etching?

    So I finally upgraded my generic laser engraver from its stock "2.5W" which turned out to be 1W. I replaced the diode with an nubm47 and am successfully etching into aluminum with the aid of black marker @5.5W. I would love to be able to etch PCB's by burning off the copper clad and avoid...

    Battery long term storage levels

    Every time I find a deal on quality 10440's and harder to find sizes I buy extra even when I dont need them. I check all the cells and charge / discharge to 3.8V before I put them away. I hear its an ideal voltage for long term storage.

    Help identifying diodes

    I think I may have overshot the current big time. This "benbox" software is super buggy. The intensity setting for high output will produce different currents at a given value each time you change the value. So where I had tested 5.1-5.2A there may have been much greater spikes. Ive got it set...

    Help identifying diodes

    One more question regarding these nubm47's So I got one installed on a laser engraving machine. Nothing special, its a run of the mill generics that was advertised as being 2.5W and was only outputting 1.2W and blew at 2.1W. I turned the trimmer up on the PCB and was feeding the new 47 LD...

    Help identifying diodes

    Only when heating up a cup of coffee! I ran the first test in the block, then the second test (post extraction) in a testing mount that tightens down with threads instead of a press fit module. The output was without lens in both tests at equal distance.

    Help identifying diodes

    interesting. I'll check that out when mounted. I didn't use a lens initially because the diodes were in the block and didn't want to fiddle. Was just going for the baseline test prior to heating to see if there was any signs of damage. The average output was 5.7 - 5.9W @ 4A

    New toys for high power flashlights

    What areas of a vehicle do police officers target? Laser guns require a reflective target to get a reading off of so police have several primary targets that they aim for when clocking moving vehicles. These include: Headlights / tail lights Grill License plate Those are shiny and...

    New toys for high power flashlights

    Wasn't comparing them, but given the nature of the post even the red LED would be overkill. That is unless the goal is not to make a point of 'back off' and enter into the realm of doing harm. Increased brightness of red may cause discomfort, but do not trigger the neutralization of the...

    New toys for high power flashlights

    lol I had the same thought using the red led out of the 'cashew' projectors. IIRC they run at 12A or so. Would have to wire up with a relay but i'm sure would be very effective. Perhaps a timed short pulse so its not so dangerous?

    Help identifying diodes

    The windows of the LD's were clean before extraction, and am not noticing any new spots or lines in the output. So I think its safe to say they acquired no damage during the extraction. I was worried some flux or indium may splash. Cant remember where I read it, but there was also correlation...

    Help identifying diodes

    I meant its a good thing they are not pressed into their seat and soldered. That would be quite tricky. Ended up setting the block on top of two AL blocks on the edges. Placed a thermal probe in one of the holes of the LD block and gently heated. Popped em out with little issue and didnt exceed...
