Boombox Bluetooth mods

I have a JVC RV-NB1 Kaboom Series Boombox and want to mod it with a "Decoder Board USB/TF/ Reader IR Remote Bluetooth/FM Audio Board Module MP3". "Bluetoothing" this box is easy but installing this module involves a bit more ie. usb, TF slot, aux, FM. IR for remote any ideas as to connecting the rest. I can't seem to find a schematic from JVC. It has an FM tuner and can decode mp3,WAV,CDA,FLAC. CD's.Plus I want to add either a LiPo 4200mAh battery or a transformer for charging the module.any ideas would be greatly appreciated. Chuck Reed

Power my boombox

I have this power supply from a device that is not needed anymore. I have 2 of them (so i can harvest the other battery for another project, or to help run this one).. It is a backup battery unit designed to power my old device even if the power in the house goes out. I have some questions about the compatibility with a project i am working on. I'm sure it's obvious to most of you, but i labeled the parts in one pic so that i could pinpoint my question. A. is the battery terminal clips B. the feed of power to the device not being used anymore C. the plug that recharges the battery So then logically D is the board that feeds power from the battery, and E is the recharging unit. The pic isn't great, but there are 2 ribbons that attach D to E. I can also provide better pics if something isn't clear enough. My question is this... I am building a semi-small boombox with a car audio head unit. Since a car battery provides 12v, and the battery in this unit provides 12v, can i use this contraption to power my project? Can i simply cut off the adapter on the end of B, expose some copper, and attach to the power of the head unit? It seems simple to me, but my knowledge of electricity is VERY limited and i don't want to burn down my house or ruin my head unit. So far, i haven't paid a penny for anything and i want to keep it that way.

Simple question, trying to make line in on casette-less boombox, can't find amp outputs

So I have this little radio boombox with no casette deck and I want to hook up my mp3 player to it. I'm trying to find where the amp outputs are so i can solder on a line in cord, anyone have info that would help me? I'll post pictures in the day time tomorrow when I can use the camera.  Thanks DIY'ers, DIY or die ps: I was thinking I could just take the spliced line in cord and probe around on the solder bumps until sound starts coming out, would this harm my mp3 player?

need some help with my project (boombox)

Hello guys so i have been working on this project for some time (i know its not complicated) and i need some help with it. So i bought this old-school suitcase it was mainly made out of plastic so i glued some plywood  on the inside of the suitcase, ive cut  some holes for the speakers and vuala its semi-completed. So im using 4 mid-range speakers and 1 low-range speakers, so i yesterday i made the first sound test and to say the least the sound quality was terrible (i know it wont be a high quality sound boombox but i have made one some time ago). So my question / request would be if you guys have any suggestions maybe you know some cheap but decent quality amp or know anything about building speakers or stuff like that ( because i have pretty close to none experience in building them) BTW im using lepai lp 838 I would really appreciate any advices or suggestions. THANK YOU! ohh and sorry if this thread is missplaced or if my english is horrible.

AT-AT boombox and iPod player

In the past couple days not one, but two AT-AT music players have popped up. One in black and one in lovely spraycan gold. While each one is worth checking out, I just have to wonder if the second one, the gold one, was really put together over the weekend as a response. AT-AT boombox Golden AT-AT iPod dock

Power supply switch for boombox project...

Could someone help me with some simple wiring questions? I've built a little boombox using a Lepai amp and some speakers. At the moment the back is off the box that houses the amp, so I can plug in a mains power adapter, but I've got a housing for 10 x rechargeable NiMH AA batteries making a 12v battery pack with maybe 20 amphours of life in it. I've only just ordered the batteries so I'll see. However, I was thinking that I'd still like to have a socket that I can plug the mains adapter into. So I was thinking about mounting a DC socket on the back plate, and some sort of switch to select the power source. 1. Does the switch need to be a 3 position one? There's an on/off switch on the front of the amp, so maybe a 2-way switch would be OK? 2. Does the switch need to be some sort of special one because it's switching power. Would something like this one do? 3. The switch has 3 terminals. How do I connect it up? I'll have +ve and -ve from the battery pack, a +ve, -ve, and earth from the DC socket, and a +ve, -ve and earth going to the amp. ...or maybe there's an easier way of doing it? Thanks.

Hard drive MP3 boombox?

I was wondering if anyone has and Instructable or has done this. I've searched Instructables and can't find anything like this at all, which really surprised me as I thought this would have been an obvious one to do. What I'd like to do is build a bookcase / boombox stereo from scratch using: 1. an old hard drive 2. some speakers 3. a small lcd to display info 4. some basic controls 5. usb port to update files on HD -or- make the HD removable 6. whatever other electronics parts are necessary. It doesn't need to have radio, CD audio or anything else. All I want is a 200GB or larger hard drive full of MP3's and a way to play them with decent fidelity and loud without using the computer. I've built lots of PC's and know computer hardware and software fairly well but have never used a soldering iron... but can follow complex instructions very well. Also I'm not sure if it can use a prebuilt interface by scavinging the electronics from a basic el-chepo MP3 player or if it would be better to use something like a VIA Micro-ATX motherboard with built in CPU and have something like a USB drive booting to a simple version of Linux directly to a media player interface? That seems like it would cost more in parts but be simpler than creating custom circuitry. But that is the way I would go if attempting this on my own. An all hardware & firmware solution somehow seems more elegant but that's beyond my current ability's. If I go with the Micro-ATX motherboard and Linux it could be done in a modular format that would allow the addition of other components latter such as CD player (with auto MP3 ripping), input and output to other components etc. So has anyone done this? If you haven't but have the know how do you want to collaborate via e-mail and walk me through it. I'd create an Instructable if so and give you full credit. Any and all suggestions, comments, rants, put downs, cheers, roars, hollars and yells appreciated!!

Charger circuit

Hey there, I'm planning to build a portable stereo speaker box thingy (you know what I mean). In order to power the 2x10W amplifier I want to use a 7.2V 1400mAh battery pack from an old RC car. As the housing of the box will be sealed I want to implement a mechanism to charge the pack. For this I wanted to achieve 3 things: -If the Power-Switch is turned on, the amp should be powered from the power line -If the Charge-Switch is turned on, the battery pack should be charged -If both of the switches are turned on, the amp should receive power from the power line while the battery pack is being charged. I have thought of the following cabling (see attached picture for a schematic) The blue box is the amplifier, the green box the battery pack and the orange connectors are tamiya connectors (the ones for RC cars) The first switch (marked in green) is a normal DPST switch which establishes the connection with the power line as well as the connection with the battery The second switch is a SPDT switch and activates either the connection between the battery and the amp or the connection between the power line and the battery. Will this work the way I think it will or does this configuration any faults? If the latter, what can I do I have to change? I'm actually really new to electronics, this if my first project so forgive me, if this setup is actually BS Cheers and sorry for the long post ^^'

Solar Boombox Upgrade

Ok so im looking to upgrade my DIY portable boombox for the 2nd time and one of the things i want to add is a solar panel to supplement the battery power from my 12v 7ah sla battery, that by itself will currently run the thing for about 3hrs at full blast. The new version will have Directed CSX-650 component speakers: (bottom of this page) and the amp will be one of these:;=43 , so what id like to know is what tech spec should i be looking for in a solar panel that would be capable of charging the battery while the boombox is not in use and will supplement the battery power to extend the run time while it is in use? Also will i need some kind of circuit/component to prevent overcharge of the battery? Oh and is there some kind of simple light/gauge i can wire in to show the charge level of the battery?

adding aux line in directly to boombox ampli

Hi guys i am Ramanta from Indonesia i have an old boombox, Sony CFS-1110s (similar mechanism with CFS-1100s) what i want to do is add an aux input to them. I have seen a lot of instrucrables about it, but nothing about this model. I find a similar unit here the aux in is conected directly to the IC Amps pin. I have the IC diagram, what i dont understand is this model have a dual IC8207k. One for each channel. TA8207K is a stereo IC, so how do i do the wiring? For single IC its just INPUT1-INPUT2-GND. In dual setting they have 4 input and 2 ground. I dont want to use any tape adapter since its sound terrible here i attach the complete diagram and schematic in PDF please give some tutorial, im a beginner in this kind of thing) hehe my email sorry for the bad english :D

How can I wire my boombox?

I need help wiring a car head unit for a boombox I am making. The problem that I'm having is that to save my settings, the head unit needs a constant 12v supply. Currently, I have a computer power supply going to the head unit supplying the 12v along with 5v for a PC fan I am using to help with cooling. The problem is that I am planning on putting in a motorcycle battery and switching between the power supply (wall power) and the battery (portable). I need all components to run off of either power source and to be able to switch between them without overloading the system or losing the constant 12v. Please help and sorry if that didn't make sense or was too complicated.

inline volume control

Hi im ramanta from indonesia i try to add an aux in to my old boombox, the reference from here i already got it working, but the problem is the potentiometer(volume). Only one channels work my boombox has 2 IC Amp, one for each channel. I already try to connect the source(ipod) directly to the amp (without the pots), work like a charm. But the sound is too loud and distorted

VHS Camcorder, Overhead projector, Boomboxes, and some other stuff.

Hey, I recently contacted my school (I'm in 9h grade) asking if they had any old equipment i could have, and they said yes. I have decided that i would *only* take 2 overhead projectors (you put a 'transparent sheet on, and projects) 3-4 boomboxes, and most importantly, a VHS camcorder. I just couldn't let that camcorder go to waste, so i decided i would take it, but now I'm wondering, what can i do with it? Also, for the overhead projectors, any ideas what i could use them for? I know, i can get the mirrors/lenses/bulbs, and fan and everything in them, but is there anything i could use them for (i know about LCD overhead projector, anything else?)

Looking for cheap LiPo 3s low voltagle cutoof/balance circuit

Looking to add portability to a boombox project I built. Want to just grab a LiPo r/c pack and use a 3a 12v SMPS to charge it with. Know of a good battery protection circuit? This will be going to a non tech minded friend. So I'd like him to just be able to plug in the PSU when he is home without the worry of overcharging and be able to run it until the low voltage cut off is hit without worrying about killing the batteries. Any suggestions? It would be for this Thanks

Usb Flash drive player?

dancing paper dolls with magnets

When in Europe, I saw a street vender that stood near his little boom box and had 2 dancing paper dolls next to it. I bought the paper dolls and now need to figure out what he did to his speakers or magnets in his speaker to create this illusion of dancing dolls that can dance next to a boom box. The dolls had magnets on the backs of them, so it had something to do with a magnet inside his boombox. Can you help? Thank you.

Solar Circuit Question

Hey everyone, first post here. I am a novice at electronics. I am putting together a solar powered boombox. I have a 30w panel, a 10A charge controller, and a 7Ah SLA battery. I will be using this to run a 12v Lepai amp. Do I need something in my circuit that disconnects the amp when the battery drops below a certain level? I have read the if a SLA battery is completely depleted it will be ruined, is this true? My charge controller only has a spot for solar in and battery out. Should I exchange it for one with a spot to hook the load?

Need someone to etch and cut a piece of aluminum for me

Hi all, I have a DIY boombox project made from a train case where I need a badge made to cover up a "mistake". I can provide an Adobe Illustrator, EPS, DWG, or DXF for the logo and shape of the badge. The finished piece will be 3.25" wide by 1.5" tall. As much as I'd like to do this on my own, I'm not keen on working with acid and don't have the time or work to build my own CNC or laser cutter. I will be happy to pay for time and materials as long as it's reasonable. Also, I'm in Northeast Ohio, if that matters to anyone. Thanks!

iPod Power ... BUT!

Here's the challenge:I have a Belkin SportCommand iPod Remote and it works great. However, it uses the iPod's connector port and draws its power from the the player. I have this thing installed on a waterproof boombox that needs to play tunes for 8-10 hours at a given time and I don't want to have to open the box AT ALL (lots of water + electronics ...).So, I need a way to have both the iPod accessory plugged in and, at the same time, charge the iPod from a 12v power source (like most car stereo iPod adapters do. I think this is as easy as a little plug to go inbetween the iPod and the accessory, but I can't figure out which pins to tap into. There are a lot of different power pins on the connector, and I need to know which two (ground and V+) are the *charging* inputs.Ideas/suggestions/comments? Thank you!

Need advice for adding aux-in/line-in to Philips AE2160/00-A AM/MW/LW portable radio

Hey there, this is my first post! :) I'm from Germany, so please excuse my grammar! :D The reason why I'm opening up this new topic is, I didn't find any instructable or guide on how to add an aux-in/line-in to my simple mono AM/MW/LW radio Philips AE2160/00-A. There's not much to find out about the technical specifications besides the standard product information: Tuner • Analogue tuning • Wave ranges FM 87.5 - 108 MHz MW 525 - 1606.5 kHz /04 LW 150 -255 kHz /00c FM/MW /04 FM/MW/LW /05 FM/MW/LW • Ferroceptor for MW (and LW) • Telescopic aerial for FM (and SW) Amplifier • Max. output power 300 mW RMS • Tone control Music /News Sound system • Loud speaker 100 mm • Metal grill Power supply • External supply /00c, /04 230V /05 240V AC • Batteries 2 x 1.5V , type R20/D cell/UM1 Connections • Headphone socket 3.5mm General • Material Polystyrene, metal grill • Weight (g) 520 • Dimensions (mm) 210 W x 150H Here's a link to a photo of the device:;=2000&$jpglarge$ I didn't even find schematics/circuit diagrams for this or a similar device. There are lots of tutorials on how to add such an input to a car radio or a boombox/stereo cassette player a.s.o., but not for a simple AM/MW/LW radio. My questions are: 1.) Are there any similar hack projects here in the step-by-step or forum section? 2.) How do I find the right connector or place to solder a 2-way-switch between the sections (tuner, amp, speaker)? After the hacking job, it should be possible to switch between normal radio listening mode and aux-in/line-in mode from an external mp3 player, notebook, a.s.o.. 3.) Is there anything else to know for this project? Yesterday I've opened up the case for the first time and looked over the circuit board and the connections. I had no cam to take pictures, but I try to take some mobile phone cam pictures of the circuitry and parts at the next opportunity! Cheers, arok1
