    help wanted making a simple like for airsoft

    a while ago I built some bike lights which though very simple do work very well and I fancy making a light for airsofting on the cheap. My bike lights used a philips masterlin MR16 bulb, an old bike light housing, standard cermic socket and was just connected to the battery via a couple of 4mm...

    regulator help (for bike lights)

    I'm curently getting 14.6v with one bulb with batteries which have been fully charged then left for a day. It drops to 13.9 with two bulbs though and would like to get a regulated 15volts to the bulbs. the power supply is made up of 24AA cells 2parrallel by 12 series but I could change it to 24...

    has anyone made flashing bike lights?

    I was just thinking it would be really cool if you could have two LED units and have them on a slow flash for road use (or one constantly on and the other flashing) You could get really it it and put a trigger switch near your thumb to activate a 8Hz strobe if someone runs infront of you trying...

    non-lethal force

    Would a 800plus lumen bulb work with a flashing function though? My bike lights take a while to cool down so I'm not sure how much difference turning it on and of 8times a second would make to it's normal blinding effect (which is rather large since it's a overdriver 35watt MR16 bulb)

    increasing circiut conductivity

    I have some modded bike lights and at the moment it's a very simple mod but I'd now like to try and get more volts to the bulbs by sorting out what I think will be a fairly big drop in voltage due to teh stuff I've used. I've currently got two banks of ten AA cells too provide a 12volt source...

    building a strob cicuit into a light. How would I?

    I have an idea that it might be nice to have a strob feature on a little light. I was thinking abbout biulding it in to a mag solitair with a 8mm LED mod It seems to me you'd save power by having a strobe and you could have something which could be "useful" on the street. Do you guys think it...

    Thats really nice Is it me or do the circes in the diagram not match up quite right? Is that to allow for metal strength (I have to write a program that invloves drawing circles you see)

    using rechargable CR123 to run a 12V system

    I don't want to use a lead acid pack, They weigh a lot and it would defeat the purpose of building the light. I could still save a load of weight over a lead acid by running Nimh AA cells

    using rechargable CR123 to run a 12V system

    Right since I'm a mountain biker I've been thinking of making a very bright headlight for it. My brother built up a nice system using bulbs with built in reflectors that run at 12V and runs on a battery which works out at about 12Nimh AA cells. I was wondering if the rechargable CR123 would work...

    my Maglite Solitaire LED mod

    would this work with a 3mm LED so you don't need to drill out the reflector?
