Can anyone help me out with my project?
I think ya'll could help me with my project. I have no experience in electrical engineering other than a 4th grade science fair project on the difference between parallel and series circuits. And 1 high school electronics project that I messed up, but still have that project & it works due to teacher tinkering with it.
So now I'm attempting to tinker with electronics. I've taken a Paper Jamz amplifier that was powered by 4 aaa batteries and modified it to be powered by a 6v 300ma ac/dc wall wort w/o destroying either.
Whoa who!! Now time to try something a bit harder.
This project is to make a attractive desktop Solar USB charger, dual stereo amplifier, mp3 player system (Pandora's Box). Seeing Joshua Zimmerman of BrownDogGadgets.com's heavy duty solar charger in a tin & USB charging circuit I believe that my project is possible. I will probably be purchasing both of them and hack together a Dual USB solar charger with 2 AA batteries.
Looking over this post could someone draw a schematic in "English" with missing parts added?
So I've started to tinker. Here is a list of all the things I have. Got pictures of some of them but not sure if I have to go pro to post.
(* Not married to some of these parts)
2 Paper Jamz amplifiers 8ohm 1w stereo speakers (each powered by 4 aaa batteries)
1 5v 200mA solar panel *
1 Paper Jamz battery pack * (4 aaa batteries) Not sure what batteries to use. Can power both amps w/ 1 pack.
Coby 1gb USB mp3 player (playback functions powered by 1 aaa battery)
1 Micro USB MALE - USB A MALE cable cut and stripped.
Breadboard, hookups for wiring. To avoid soldering.
Audio hookups: 4 3.5mm M - M, 2 3.5mm F - F coupler, Stereo Y adapter 3.5mm M - 2 F Y adapter
Cigar Box enclosure. Internal dimensions (open no lid space): 2.25"h x 7.5625"w x 6.1875"d. external closed: 2.6875"h x 8.375"w x 7.0625"d
So I've powered both of the amplifiers with one set of AAA batteries. I'm thinking that they can be powered by the 2 AA batteries from the solar charger. Let me know if I'm right here.
I would like to attach my USB micro male whip to a circuit, through box to charge my BlackBerry PlayBook. I think it needs 5v 1.8a for charging. Don't know if it also needs fake data voltage for charging. I've tested my phone with the USB micro whip, AAA power pack & it charges. For ease of construction I'll be using the breadboard & hot glue circuit parts together.
Seeing that the mp3 player only needs power from the equivalent of a aaa battery, what is the best way to reduce the amperage from the two AA batteries so not to burn out the Mp3 player? Going to mount it against side of box with USB MALE adapter going through back wall. Use dowl rod pieces for buttons on side, battery hookups faceted inside.
All components sending/receiving audio via 3.5mm audio patch cables. Paper Jamz amps wired in parallel through breadboard to power pack. [power pack, breadboard (not mounted)], audio ports, speakers. Speakers mounted to sound board suspended from lid. Would like to mount solar panel on outside of box lid.
Nothing mounted is set in stone but the audio ports & speakers are fixed in place.
Thanks in advance hope ya'll can help here. & if your going to Maker Fair Detroit this weekend have fun.
Remember to Zombie proof your projects.
