    "appraisal"/advice on pricing

    I've got a post in the "Buy, Sell, & Trade" section, but I need some sort of informal "appraisal." Please see http://laserpointerforums.com/f39/possibly-sale-stingray-ii-405nm-253mw-peak-55667.html for more details. DISCLAIMER: It is not my intent for this to be a shameless plug for my "Buy...

    FOR SALE: Stingray II (405nm <253mw [peak])

    [edited to added price] $120 shipped OBO (I am so sorry; $120 shipped to the continental US. I'll ship overseas, but I'll have to add more for S&H. [I added the price so hastily to my post that I forgot to include that detail.] My apologies for any inconvenience this may have caused.) [see...

    Want to sell/trade Oakley Metal Plate (Rx) frames

    Due to my lack of attention and poor planning, I am now the proud owner of two (2) pairs of matte black Oakley Metal Plate (prescription) frames. One set it at the optometrist getting filled with my prescription. The other set is in transit to my house schedule to arrive in the next couple of...

    phosphorescence and Blu-ray

    After I got my Blu-ray laser a few months ago, I thoroughly entertained myself by shining it onto the phosphorescent screen of my CRT television with the lights turned out; leaving a [brief] glow-in-the-dark trail on the screen. Then naturally (as I'm sure many of you have probably already done)...

    edited to add: SOLD I have acquired a brand-new Wicked Lasers Advanced 35mW model laser. It retails for $139.99 at WL. I don't need it. I'd be happy to get $90 out of it, but I am open to all reasonable offers.

    Li-Ion 18650 question

    Mods, move this elsewhere if need be.  Anyway-- Do Li-Ion 18650 batteries ever peak higher than the norm of 3.7V.  I ask because I have two 18650s that my multimeter shows are well above 4V.  One reads 4.15V and the other at 4.25V. I tested numerous other batteries whose voltage were within...

    RPL voltage

    Does anyone here know what the voltage is regulated at in a [non-adjustable] RPL? Just curious. Thanks

    question about voltage for 405nm pointers

    eBay user heruursciences sells these 405nm modules quite often. My first observation is, his units take a AAA battery. I'm just wondering what he has done exactly to work down the voltage on these diodes. It seems that most 405nm modules use substantially more voltage than 1.5V My first guess...

    Anyone interested in an RPL

    Just wondering if anyone is interested in buying an RPL unit. I got the thing from pseudo over a year ago, but it tends to just sit on my shelf most of the time. I'm not 100% sure of its average output now, but when I got it, it was outputting about 330mW. The last I checked it (back in July or...

    SONAR CASES [all sales have been finalized]

    ALL SALES HAVE BEEN FINALIZED; thanks for looking Feb. 5, 2008: So back in September, I attemtped to sell four (4) Sonar cases that I have.  They've been sitting on my shelf (obviously people were not willing to pay my asking price.)  So I am revising this post.  Obviously I'd like to...

    different battery direction

    I know that most handheld laser devices have the battery/batteries going in into the case negative side first; putting that end closest to the diode. And other lasers are the other way around, with the positive side going into the case first; e.g., IIRC, the old-style Pulsar (I'm not familiar...
