Here is some new imagery for your amusement.
Concept art and fantasy laser images
As part of the ideas behind these concepts, I recall a science kit I had as a child with a small parabolic reflector. It had a small attachment with a holder at the end which, when it was pointed toward the...
Some folks have asked about the optics mounts I made. So, here is some detail. You can see some nice beam experiments using these in this LPF thread and more at my lasers page here. Larger (800x600) images are linked to the thumbnails shown below.
Of course, if you need scientific precision...
I hope everyone had a safe Halloween weekend. November already:eek:?!
I received my optics kit (nice set of lenses, prisms, mirrors, filters, gratings) from Jack, so yesterday I headed to the hobby shop and got myself some balsa wood, an engine mount for an RC airplane, some clamps (the dude...
Wow, they have some beautiful new graphic images of product, and they also have a public saftey message about pointing at aircraft.
Not bad, I must say.
I have a NEBO model 5050 which (like many of their similar items) has a red laser pointer. It travels quite far. I pointed it across a dimly lighted parking lot at night and the dot was smaller than the size of a baseball at >400 feet (they claim it reaches 450 yards). As low output pointers go...
I've seen some hilarious slogans, phrases in many signatures here, and I was thinking of some funny thoughts for bumper stickers (of course you might see them on T-shirts, e-mail sigs). I'll start with a few you may recognize based on other phrases. You get the idea. This could be a funny...
This is not a priority for me (like one member sez, "if you want to burn stuff, get a lighter"), but a popular topic and many questions are about burning stuff. So, let's have some fun...
I set the laser on power level 3 for these tests, and set it about 5 feet from the target. I laid a towel...
So, I found a few posts regarding back reflection and possible internal damage.
My question is about the aperture being closed. Many portables (such as my RPL-400) have a small slider switch to block the aperture. I guess this is primarily to keep out dust when it's not in use. Is there any...
These were taken in my office with daylight. The laser is set at the lowest power (1 of 9). The blue LEDs on the Beast are a nice setting, and the brand of DVD-RW is fitting, eh? A friend had given me the Obiwan figure years ago. Concerned, he seems.
Here, I donned my safety glasses and...
Hi,
I've been fartin' around here for about a week now, so it's time to say hello, and get to know some of you.
First, let me thank you all! I had finally decided to give in to my desire to own a "real" laser (the pointers we play with in the conference room at work don't count), and in my...
