    Empty Waterproof Enclosures for Custom Diving Electronics

    I am designing a product for diving applications and I'm wondering if anyone knows where I can buy an empty waterproof enclosure, like a flashlight but without the internal bits, for testing some prototypes. Or is it easier to just buy a dive flashlight and remove the guts? Any ideas on cheap...

    Review: Fenix HL12R

    GREAT review, going to purchase one. Just haven't decided on this one or the hl30r yet :) Fenix if you're reading this... sell the headbands separately!!

    Small UV Flashlight that accepts NIMH

    Looking for a cheap, small UV Flashlight that accepts NIMHs. AA, AAA, I don't really care. $10-15 ones are all over Amazon, but with questionable quality... A lot of them have like 9 or 15x LEDs which is pointless. I'd rather have just one good, focused LED than 12 cheap SMD. Anyone have one...

    Converting electronics from alkaline to Li-Ion?

    perfect, this is essentially what I'm going to do. thanks! Oh I've got plenty of Eneloops :) Will the circuit that I linked be sufficient or do I need something else? Got any examples / alternatives?

    Converting electronics from alkaline to Li-Ion?

    I need some new projects to keep me busy. I was thinking of converting some electronics designed to run off alkaline batteries to instead take rechargeable lithium ion batteries. I have batteries lying around from old cell phones, digital cameras, etc that still hold a charge. I also have some...

    Off Road LED Light Bar 8-20"

    looking for an offroad LED light bar, hopefully someone can steer me in the right direction! I'm new to all of this and don't know what to look for. I was just browsing SuperBrightLEDs and they look pretty good, and i'm satisfied with their replacement bulbs which replaced all my interior...

    Fenix CL25R alternatives?

    I want an LED lantern powered by 18650s. I am about to pull the trigger on the Fenix CL25R unless someone wants to sway me otherwise :). Are there any good alternatives in the sub-$100 range? I want something compact for casual camping, not those emergency survival ones that are huge and bulky...

    9V Rechargeables - LiIon or NiMH LSD? Max Voltage?

    I have some high-current applications that unfortunately require 9v batteries. I hate the wastefulness of primary batteries, most of my electronics have NiMH LSD in them including my flashlight. Maha Powerex makes 9.6v NiMH LSD but they are cost-prohibitive at $10 per battery. They are...
