Like the names imply, the fine and coarse controls will work together to adjust the outputs that you want. For instance, if you wanted to set a voltage output to five volts, you would first put the fine control to its center position and then use the coarse control to get as close to the five...

No, you can't get any kind of permit to legally blind someone. I truly fear for the future of our hobby. Ed

Hopeless!

Re: New Host Available for Pre-Order: The Survival Laser S4X Wow, you read my mind. :thanks: Ed

You asked this question and received reply's and information links in this thread: http://laserpointerforums.com/f44/how-do-you-adjust-drivers-current-94764.html Why don't you read what people have already told you and ask your questions in that thread if you can't comprehend their answers...

It sounds like you didn't have any lasting damage then, if you can still see fine detail. There is a very small area of the retina that really registers fine detail and that area must still be OK. When I was younger I used to read scales on slide rules and vernier calipers with ease. At...

And those same people are surprised to learn that a pound of gold weighs 12 ounces. :huh: Ed

My order was shipped out the same day I ordered it. I got it a couple of days later. Probably depends on his local post office schedule. Ed

That sounds fortunate that healing was possible. Did you do anything in terms of medications, vitamins, or other treatment to promote the healing? Have you had a retinal examination by an ophthalmologist to confirm that there is no residual damage or is it possible that your brain might be...

Many years ago I had a bad experience with Ray-O-Vac batteries leaking so I switched to Duracell. After that I found that the Duracells would leak too. I think that any alkaline battery has the potential to leak. It seems to be mainly related to battery age and discharge state. The older...

Payment sent for test load. Thanks, CoherentRays

I would definitely second Pi R's advice about removing batteries for long term storage, especially alkaline cells. I've had expensive electrical equipment messed up with corrosion in the past from leaking alkaline cells. Ed

Re: Second Build, 405nm ~650mW PIC HEAVY... i killed it, literally :'( Nice pictures. Too bad the "learning experience" turned out to be a bit expensive. It happens to all of us in one way or another. Keep at it. Ed

In my case, my wife is so violently allergic to chemicals and especially insecticides and herbicides, that the slightest whiff of them can be as dangerous or even more so to her than the sting of a wasp or hornet, so I think a laser would be my best choice if I needed to destroy a nest. The...

Only problem is, when you're vaporizing the insect, you have to be aware of what will happen to the surface the insect is sitting on. Shooting down an insect in flight would be a fun sport, as long as you're careful to not bring down an airliner with it. :yabbem: Ed

In all of the posts in this thread I don't see where you have ordered a battery charger for those batteries. Usually these batteries are sold and shipped with only a partial charge on them so you will need to charge them before your first use. Xtar, Opus, Pila and many others have good...

Those oversized pictures are a pain even with a large desktop monitor. If I resize the browser to show the whole picture then the text is too small to read easily. Ed

Wow, Thank you, Dr. Evil, for starting this thread and then bumping it back up into view. The items in the first post so perfectly described me. I'm OK in a one on one situation but in a crowd I'm pretty quiet, content to just listen, observe and learn. A few years ago when I was talking...

Here's a little fellow I was playing with a few years ago: As far as I know, he's still alive today. Ed

I tried to order a test load either assembled or as a DIY kit. The sales page says sold out in either configuration. When will you have more in stock? PM sent. CoherentRays
