    well,earlier today somone posted somthing about making a whire radio (jokingly) and that got my brain turnin im not gonna even try it with the white wire, but if i got a 12 vold lead acid battery, and a thrift store radio, would it not be possible? i dont think the radio part would work very well, being a stationary radio moving... but if i found a small radio and dismantled it and somhow mounted it somwhere if its small enough, in my project box. and get a whole system going.... blinkers lights etc. i know i could get it to work, but is there some JUST PLUG IN THE WALL way of charging the lead acid battery? i wouldnt know cause ive never used one..... thanks and any info will be appreciated!

    Yeah you could get a charging port and smart charger for a simple SLA battery. Check out this site http://www.electricscooterparts.com/
    I've bought a good amount of stuff from them, quick shipping and nice electrical parts on the cheap. I use insulated connectors so I dont have to worry about soldering anything. Also gives you the ability to disconnect and rearrange your electrical system.
    Having a radio on a bike that would be audible while riding would have to pull some major wattage though. You'd need some high powered speakers and a good deck for it. So to me an on the go system doesn't sound feasible. However if you wanted built in tunes for those times you wanna park your bike and chill with friends or something like that you could probably get that going just fine. In any case, it's always interesting to see the projects you have buzzing around in your head dude. Keep it up you may just rock the MB world.

    ill take that as a compliment lol, but i got the idea, cause my dad is doing the same thing on his 86' harley softail. but in a molded fair-ing i dunno how to spell it.i realise it would take a bunch of volts, and thats why i wanted to get somthing rechargeable..... i actually have his old harley bat. trying to see if i could use it somewhow, instead of paying 15 bucks on 1 battery! guess that doesnt compare to the 70 dollar 1 he gave me lol. he said it didnt hold a big enough charge for his drag engine.... i probablly wouldent even use it all that much... i usually just use my mp3 in my helmet, but only use 1 earbud, and make it barley audible, so i can stay alert. but if that battery isnt 20lbs lol i might use this idea on my push bike at the very least, cause i do wanna lose some weight...

    My 5ah SLA must weigh a couple pounds at the very most. You'd probably want 7ah depending on how long you want your tunes going. When you think about it you definitely get your moneys worth since these batteries can be charged up 300+ times as long as you don't abuse them by deep discharge. Even still I think having a good system on a bicycle would be too much bulk unless you made a system right into a saddle bag setup so everything could be self contained, hidden and waterproof. Why not just look around flea markets or something for an old/cheap portable boombox. Look for one that uses 8 C or D cells if possible to make the required 12v. Then just tear everything out of it and mount in your own saddlebag setup. Speaker on either side, radio guts in one bag, battery in the other and you should have plenty of extra space for storage and extra power for a good lighting system (which is a must IMHO.) You can mount the speakers wherever you want on the bike with adhesive backed velcro and tuck them back in the bag when riding in bad weather or when not in use (or even when taking the saddlebags off when you park/lockup the bike) You could even look around for some small used all weather speakers so they don't get destroyed even if you do decide to kick up more roostertails in the slush with tunes going. I've heard boomboxes get pretty darn loud I wouldn't doubt you being able to hear them while motoring around.

    thanks jake, i am going to wire this into my turn signal project. i would be more than happy to have saddle bags, but where do i get any? (for a decent price?) thanks. im thinking of finding a radio that has the old style dial that will fit in my project box. cause the radio stations round here do what they like to call "10-in a row rock blocks" and that makes for very long commercials. and i want to change stations. so i might just tear up a clock radio and hook up some beefy speakers. 1 last thing. where do i get a charger for a battery like this? http://www.radioshack.com/product/i...tery&kw=12+volt+sla+battery&parentPage=search thanks.



    my bad jake, i didnt read the 1st post duh.

    I run a sirius satalite radio on my MB. The satalite radio is already built for 12 volts, has a headphone jack, and is small in size. My receiver only draws .5 amps, so a small 2.2aH 12 volt battery is good for a couple hours of ride time. Oh, and there is no such thing as commercials on satalite radio!

    On your battery... most 12 volt sla batteries will list their maximum charge rate on the battery. A small 1.2aH battery, you would probably want a simple wall plug charger with an output between .2-.4 amps. Available at various web stores or local electronics store.

    Depends on what type of charger you get. Some come bare wired, but most should come with alligator clips on the ends.

    Yes, the white wire radio was joke and to be honest, I'm sure that you would get too much interference. I'm thinking you would get a buzzing sound that changed pitch as your motor revved up and down.
    But, If you really want a radio and after reading this thread, I'd say you do, why not just go with an old stereo out of a scrap car. It's been many years but I used to do this, It's simple and cheap and as you know, you can sit in a car for hours with the radio playing, hours and hours if you think about it. You would have to mount speakers and a battery but that is not a big problem. Just make sure that you get the plug/wires that come from the stereo if you go to a auto scrap yard as it's a real pain soldering wires to the posts that the plug would slide into. It would also help if the wires or the stereo itself had markings telling you which wire goes where..eg. red=positive,
    green =left front ..blue=right front ....that sort of thing.

    Most that I've been to have a shelf in the front office full of them, but those are taken out because they can ask money for them, or you could look around for a rust bucket around your area. Just remember that newer push button radios have one wire that is always "on" so that the radio remembers your stations. Not a big deal but I'd look for an older dial radio for 10 or 20 bucks.

    With this kind of info you can do it in a half hour and you do not have to use all the speakers , just do not let the unused wires touch each other. The "accessory" wire is the one that is the memory and is always on power, unless you want to program the channels in every time you start up the bike.
    You could even go with a small amp or booster and a sub woofer (boom boom box) but everything takes power. Also, I would not use the "ground" of the bike frame. I would just go right to the battery with the ground so that it is not getting any bad **** from the motors magneto. Oh...by the way, don't forget an antenna

    Glad I could help and I wish you luck with your hunt and if needed, don't forget to ask before shorting out a wire.
    After you get that going we can work on

    I'd go for a much larger battery than that dude, especially for that price! 1.2ah probably isn't going to last a long time running speakers loud enough to be heard over that 2 stroke. It'll run even less time if you put a lighting setup on the same battery (and why wouldn't you, do you really wanna charge 2 or more batteries every time you get home?) And on top of that if you DO run these SLA batteries down below 10v you can cause permanent damage to them. You want to always be sure that you're going to have power to spare and that charging isn't going to be a pain in the butt as its best to recharge them asap after use.
    With my lighting system I used 16ga automotive wire and a ton of parts from that electric scooters part site. There was no soldering involved just some cutting, stripping and crimping. I used a bunch of insulated tab terminal connectors to hook up all my components. You'll have to be sure to get a multimeter too just to make sure you're getting your polarity correct or you will destroy your electronics or start a fire. Always place a fuse as close to the hot terminal (+) as possible just in case something shorts out.
    Maybe you could get a pannier bag setup built for Ebikes. some of them have two side bags and a top bag meant for batteries/storage. You would just have to find a way to mount a rack on the stingray, the rack would probably require some modification since the rear wheel is so small on them and the seat is further back than common bicycles.
    I like the idea about the car stereo much more than the boombox however you would probably have to keep it as one solid unit. Which means if you wanted to put it on your dashboard it would be incredibly clunky. A boombox dial would be just as difficult to incorporate into a dashboard. I've taken them apart before and it would basically involve re-engineering the whole dial mechanism and syncing it to the correct frequency again In either case you'd have tons of wires mounting anything up on the handlebars like that. I would think it would also be a ton harder to waterproof exposed like that rather than secured and under the flap of a bag. The push preset ones would be perfect, I'm pretty sure modern LCD radios suck down more juice too which is not favorable on a machine with no alternator (yet) :)

    If you want I can assemble a parts list off that site for you. I can vouch for them, I have my electronics box almost complete (just have to mount it on the bike, hook up the brake switches and headlight) and every component works perfectly. I think their stuff is chinese but what isn't these days... In either case I didn't receive anything that was overly flimsy, defective or even rough around the edges.
