Alright everyone, I made a simple speaker system in my backpack...
It all started on christmas break when I was grounded and had nothing to do. So, I stuck a broken pair of headphones in my backpack thinking.. hey, you might be able to hear the sound! Then I got creative and took apart my 'HandyPack Color' for my gameboy (its a magnifier+sound amp) and stuck it in there. When I got to school I played it, but decided it was not loud enough.
So.. I took .5 watt speakers and replaced the small ones... bad idea.
When I let someone play their little ipod, it played loud, but afterward their ipod had a high-pitch sound until he took out the batteries... not sure of any long-term damage.. :icon_sad:
So, one day I had an idea. I looked on the internet for a nice, small pair of computer speakers. I found a cheap $15 set at RadioShack, so I went off and bought one.
I got them working off of batteries and it was awesome! (The first pair I bought got fried because I got the + and - on the battery case backwards) So, I'll show you how I made them and show a few pics of the final product.
What you'll need:
-Cyber Acoustics Amplified Desktop Computer Speakers
-8 AA Battery Holder
-5 AA Batteries
Alright, after you get your stuff, here's what you do.
First, get the AC adapter, and cut it. Make it long enough so that where the speakers will be and the batter pack will be can connect. (Mine is directly under, wraped in paper so that nothing touches)
One of the sides of the wire has a white strip, this is the negative wire.
Now, get the batteries in the battery pack, this is where you get creative. I used a paperclip to substitute the 6th battery and small wire to connect the 7th and 8th battery pins together.
I just happend to have a 9-volt battery clip, so I used that to connect the battery pack to the AC adapter, but you could also just run a wire on the inside and connect it. Lastly, I cut a white piece of paper, then rolled it around the battery pack and taped it so that nothing external touches it and connects wires together.
2. Taking it apart:
Alright, now you need to pull outward on the foam part, you should have just removed the front. Take out the four screws, then remove the face plate. Remove the last four screws from the speaker, then discard the faceplate.
Alright, heres the tricky part, you need to cut the wires, then re-assemble them after removing the speaker case. (In case you didnt notice, you cant remove the speaker from the black plastic casing!) So cut all the wires, then put them back together.
3: Installing the speakers:
Ok, find a place to put them, and.....well... put them in there. I simply used some Nylon thread and sewed it in there. (Nylon thread is REALLY hard to break). If you have a better idea, go ahead. Just make sure that the metal speakers dont touch the circuit board. I made the cool little blue LED stick outward, so you can see it through the backpack.
So there you have it. By the way, these speakers are VERY loud, and you have a volume control in the circuit board for easy control. If anyone actually does this, PM me with some pics or something. Oh, and I'm actually selling this. I have at least 1 more customer.. Im selling them for 30 (20 for parts, 10 for profit).
Oh, and one more thing. I haven't actually found a real use for them, although lots of people like to see them in action!
Pictures attached, pretty bad quality on the third one, though.
