    Has anyone tried DX SKU #123406?

    I'm looking at them to use for lighting at an outdoor event; given the possibility some of the lights might "go missing" I don't want to use anything expensive. I do realize the claimed brightness (250lm) is only potentially reachable with a higher-voltage rechargeable I'm not going to be using...

    Just wondering - 18500 => 3-AAA carrier adapter?

    Just wondering if anyone's ever made an adapter to run a light that uses 3 AAAs in a carrier from an 18500 cell. My "just curious" solution - wrapping the cell in some thin foam and using a 5mm thick magnet on the tail (negative) end works, but isn't very "cool". ;) Granted, I understand not...

    Constant-current driver for lantern upgrade?

    While buying some other items, I ran across a disc-type hanging lantern, and decided "what the heck". [My tent is on the small side, I'm fairly tall and I'm tired of bonking my head on the lantern I've been hanging in the top of the tent.] 48 white 5mm wide-angle LEDs, run direct-drive in...

    Annoying Abbreviations

    Some time back, I started seeing a lot of people online using the expression "FTW" more and more often. This confused me, because the only meaning I was familiar with is the one commonly used in biker culture, where it stands for "F**k The World" and often that didn't make any sense in context...

    Brand Loyalty

    What food items do you insist on a particular brand for, even if other people insist "they're all the same"? In another thread, march.brown was declaring his love of Lidl's Mango Chutney, and that no other brand would do. For myself, as a peanut butter fanatic - it's JiF Creamy, or nothing...

    A Work In Progress

    I've mentioned before that I occasionally go camping with a group of friends, and I had this idea for lighting up my campsite: The "body" of the unit is a Strecket aluminum cabinet/drawer handle from IKEA, 2/$4. I stink at fabrication, so I prefer to look for items like this that can be...

    Embedded Tritium

    I'd love to see a flashlight with a tritium glow vial embedded in the power switch. For an electronic switch that would be easiest, as such wouldn't necessarily have to have a flexible boot and could be some tough clear plastic like polycarbonate or Tritan. I imagine that it would be more...

    Trail Marker Lights

    Before my question, a bit of background: Every Labor Day weekend, I go on a camping trip in the Sierras hosted by a local club. The campsite is a primitive one, fairly heavily wooded and a few years ago the "LED throwie" concept gave me the idea to create trail marker lights - so if someone had...

    HELP! Optics for the output of an RGB LED color controller

    I haven't seen anyone mention this RGB LED controller here; it strikes me as pretty nifty. ;) I plan to build one and have it drive 6 1w LEDs - 2 each of red, blue and green, arranged in a hexagon, the hole in the center being where the wiring will pass into the casing. The problem is ... how do...

    Request: Help Finding Circuit Designs

    I'm looking for two circuit designs, and hope y'all can point me in the right direction. The most important is a "darkness switch" to turn on an LED-based light when ambient light fails. Most of the circuits I've seen are asking for 9v or more - I need one that can run off the 3v that's running...

    "Stealth" Mag Upgrade

    I've been thinking about this for a while now, and I'm throwing this out to those here who know a lot more about this than I do. I recently had the idea to modify a standard Maglite flashlight such that it's not obviously modified - but has had its performance substantially upgraded. If someone...

    Reusable Cell Phone (&c.) Chargers

    I've found these little gizmos to be really useful! Not only can they recharge my cell phone, but (with the right adaptor) also my PDA and almost anything else that one can charge off of a USB port. The idea is that they take one or two AA batteries and boost the voltage to around 5v. I now own...

    Looking for the right LEDs....

    Greetings, all - I'm new here, hope I'm putting this in the right place. I made some trail-marker lights for a group camping trip I went on over Labor Day weekend from some white LEDs I bought from BestHongKong.com a while back, CR2032 coin cells and tape. Granted my trail marker lights didn't...
