    Well I hope im helping you with this. From your pic, you have what you need, however, ive never used a toggle switch. One though is that your gonna have to get the smaller battery pack so that you can get the 12 Volts needed, or els it won't run to its best. So thats what you should do.

    Just curious, because I just saw the picture for the first time, because my PSP wouldnt let me open it. I imagine you could use the toggle switch, assuming it works in the same way as the switch I have, because the toggle switch appears to be one way as well. I would just be concerned with how you would want to mount it inside. Dont get me wrong, it would work, I'm just suggesting probly trying to find something flatter. All the parts I used did not all come from the same Radioshack, because I could not find everything I needed. Now you have the fan, it runs on 12 Volts. At first, I ignored that really, and I just attached two AA batteries to it. In order for it to move after I fliped the switch, I had to boost it with my fingers, and then it would run. I had to 2 of them on the fan, so only one, I can only imagine wont run well at all. Trust me, it took awhile for me to realize that, I just thought the fan sucked at the time. So you just need to get the appropriate battery holder. I recommend going to a different Radioshack, you may have more luck. Your only other option is using 6 AA batteries, but thats unecessary when you could only use one.

    Just another thing about the button switch you have. It looks like it has two black wires coming from it? Ive never seen that before, but then again, Im still learnign about it as well, so you could just experiement with it, and see what happens. Just get the correct battery holder, and it should be smooth sailing from there.

    Yeah, I kinda thought the AA battery holder wouldn't work, but I'm sure I'll be able to use it elsewhere to power a few leds on the RF don't you think? I went to Radio Shacks site, which I should have done initially, and finally think I know what parts I'll need. The "N" battery holder part #270-405 is the one you used, correct? And I also found the slide switches you mentioned as well, so I'm going to go ahead and order it all after I'm sure that the above part number is the one you used-it must be as it's the only "N" battery holder they carry as far as I can tell. I wasn't sure how I was going to mount the mini-toggle switch-probably epoxying it on it's side after grinding it a bit flat on one side. I'll just use them on my gauntlet later on down the line. Now I just need to learn how to wire a series of leds back to one or two power supplies/battery holders...Can anyone point me in the right direction? Thanks again Chris, you've been extremely helpful as usual...

    Re: Diving Head First Into Electonics...

    The "N" battery holder its the correct one that I have. So far t=you have everything for the fan. I dont know how exaclty LED's would work, perhaps if you post some pics I could make a logical guess, maybe they may function similar to the connection of the fan. Are you planning to put this on the RF front? Or the interior part that faces inward on the RF? I have heard of methods that use a ball bearing I believe, so that when you lower it, the ball rolls forward, and the LED switches on, and turns off when the RF returns up to its usual position.

    Just to throw this out, I had an idea while on the bus to a marching band compitition. As I notced everybody's several hundred dollar cell phones, I noticed that, especially on the flip phones, they have mini screens. I had the idea of if ever possible, to get hold of a cheap phone, and dissassemble it, removing the small screen and seeing if I could control it to some affect, and put it on the RF. Would be awsome if I were able to do something like that. Just an idea.

    Now that I think I have a handle on helmet fan project for the most part, now I want to move on to leds. I want to just have some leds here and there on my armor-like the two in the MQ-1/key slot area on the helmet as well as the range finder and gauntlets etc-some always lit and others blinking. I figure I can use a similar power supply/switch as used in the helmet fan project but I have one problem. I'm not sure what the receptacle that the led itself is plugged into. See what I'm looking for? I have the leds but I'm stumped on what I need to make this happen. And what will I need to make some of the leds blink-and anything else I'll need for the project? Thanks guys-sorry, but I'm NO electrician to say the very least...

    Re: Diving Head First Into Electonics...

    You know, after realizing how much humidity in the air and ther amount of heat there was on halloween, Im thinking about upgrading to a larger fan. Good thing is, even the larger fans Ive seen still run on 12v.


    The LED's I imagine needs a board to sycronize the blinking. Ive seen them before, and I think the hyperdyne servo control board actually does come with two led lights that work in sync with the servo moving up and down. Kinda funny, can kill to birds with one stone. Unless, you can try to buld a circuit board. I know that at a radio shack, they have all the parts so you can construct something, the thing is, you need to know what to do. lol, thats where experimentation comes in, because I have no idea how to. I have actually thought about this, something to try in the future. Was just wondering if anyone before has ever thought about using a small cell phone screen to manipulate to put in the rangfinder, woould be pretty cool.

    Re: Diving Head First Into Electonics...

    This is my kind o thread!! I'm a college student at Cal Poly Pomona, major in...... yea electronic technology!! if yea seen my friends C3P0 outfit i made the eye lights and fan in his helmet work.... not to mention rig it so the power supply was in his back!!

    LEDs are nice little lights, but they really don't "plug in", yea sodder them to wires. be extra carful due to they have a charge, you must make sure the posative side of the batter is hooked to the posative side of the LED..... i asume you guys know this

    any questions, i can most likly answer..... ok i will try and answer. Blinking lights, may i recomend useing capacitors?... they are fun and can discharge and recharge at a rate you want thme to... but that may also be more complex... too long of post, sorry!

    Re: Diving Head First Into Electonics...

    one more thing, if you have pictures of things you need help with, i could help yea out.

    Ha, finnally someone who knows what their doing unlike me trying to learn it through trial and error, zappin myself, only endin up to look like Albert Eistein's hair. I managed not to long ago to replace a whole light fixture in my house's laundry room. The electrical wireing was old and caused some issues, so I had gotten a new whole floresent light fixture, and replaced all of it.

    A question to Marx, is your major closlely related to electrical engineering? I am planning on doing this when I get into college. Thanks for your help!

    Re: Diving Head First Into Electonics...

    I see-well sorta.I assumed that the wires/leads coming directly off the led itself went into some kind of receptacle rather than just being soldered directly to the wiring. I assume you just tape it up after and affix the led where you want it? How about power supply for two leds? Would they work off of an AA or couple AA batteries? I know my maglite led kit for my flashlight runs off two AA's, and that's three leds total. As far as capacitors, do you think you could be a bit more specific. You're talking to someone lacking in the technology department. Perhaps you could pick a specific capacitor that would do the job for us as I'm sure many of us want red leds here and there on our armor and buckets etc...And thanks alot, it's nice to have another person familiar with electronics here to help out!!!

    Re: Diving Head First Into Electonics...

    ::craks knuckles::..... ok first, yes my major is that which you think. The diffrence is... well lets say engineers draw up plans and i will be makeing them

    alright forget the capacitors... and much else realy.
    go to http://electronics.howstuffworks.com it tells all on how stuff works... so if you want to make something new go there, type it in and see how it works

    second, i belive many people here have done LED things, (light emitting diode) and i bet many will help. If you need help makeing lights flash on a gauntlet go to the gauntlet forum and begin a discusion on such. if they don;t help.... well i will try my best.

    Re: Diving Head First Into Electonics...

    Thanks for the link, I definitely could use some info on how this all works. I'll also check the gauntlet/armor area and perhaps create a thread on the subject. I'll figure this all out eventually.
