Old Hi-fi with no line-in

Hello everybody,  I found an old (5/10 years)  Kenwood small hi-fi system. It has a good sound, but I wanted it to connect to my laptop. The problem is that there is no line-in or any other form of input. Since it has cd-reader and a tape reader I though I could create an input removing the tape reader and using the connection tape->amplifier as my new line-in. Is that possible, any help or instruction? Thanks, bye

Building a home Hi-Fi using 12V car sopund components

Many years ago I used to have big sound systems in my cars. I grew out of this but am left with the parts, i.e. speakers and radios and amps. I would like to build a hi-fi system using these parts. I’ll need to build enclosures for the speakers and radio and amps. No problem. My problem revolves around how do I power this setup? Using a charged car 12V battery is the simplest option and will give the cleanest sound, but that will have the problem of maintaining the battery using suitable charging mechanisms. The other option is to build or buy some kind of 12V power supply that can run from a household 220V AC power socket. The problem with this is, that the power supply will need to be able to handle large currents, to the tune of 90 Amps!! How can this be done?

Adapting powered pc speakers to hi fi speakers

Adapting powered pc speakers to hi fi speakers - New! by JayWalkerLeo - 10/21/09 9:16 AM Does anyone know if it is possible to take the power unit out of a set of powered pc speakers and put it  into a set of basic hi-fi speakers. The reason is the left speaker of the pc set does not work properly but all the amp bits work.  I have a pair of 20 (10+10) watt hi-fi speakers nothing special at all, but I wanted to know if i could swap the amp bits with all the cables from the pc set to the hi-fi pair without too many adverse affects. Any help or advice is most welcome

Adding more speakers to hi fi stereo?!

Hi, i was just wondering whether anyone knew of anything that will allow me to add more speakers to my sony hi-fi without losing in volume. my stereo only allows me to add 2 speakers, and i have seen that you can get stereo speaker splitter allowing to add more speakers but i don't know whether one of those leads to a loss in volume aswell. I was wondering whether there is anything like a booster/amplifier to prevent the loss (almost like an aerial booster for TV's). Any help would be great thanks! Dan

Arduino Car

Hi, So in computer engineering I've got to make a arduino based car, I've added a whole bunch of features such as IR tracking, obstacle avoidance(proximity sensor), optical tracking(follow a black line), and remote control through an android based phone. Since I'm a total newbie to technology I'm having trouble. I would appreciate it if You guys can point me towards resources and arduino libraries(for coding) that will work for me. Right now for coding I've only got basic pseudo-code setup since I do not know what libraries to use. I have searched up many sketches online and looked at them but didn't really understand any of the code. Here's the basic pseudo-code I got setup on the things that I've got to work on: DC Motor (4 of em for the wheels) (I also plan to add a stepper motor for turning right and left so if you could direct me on that as well) //Import necessary library //Setup the motors and pins //If signal for forward received //Code for moving forward //Set speed //Else If signal for backward received //Code for moving backward //Set speed //Else If signal for right received (keep turning right till stop signal received) //Code for moving right //Set speed //Else If signal for left received (keep turning left till stop signal received) //Code for moving left //Set speed //Else If signal for stop is received (Should we slow down to a stop or just stop?) //Code for stop //Set speed IR (I've got transmitting and recording diodes) //Import Library //Declare Pin for the IR Sensor //While loop: Move Right //If IR signal is received //move forward //Else //Jump back to top of loop Proximity Sensor (obstacle avoidance mode) (I might either use the one from Lego kit or buy a separate one ) //Import Library //Declare Pin for proximity sensor //While Loop: Send out sonar(echolocation or whatever) every second //Is there any obstacle?   //Yes, turn right so many degrees, and go back to while loop   //No, move on forward at set speed //If you’re surrounded and cannot exit send out a message through flashing LED's ________________________________________________________________________________________________________ I'm not asking for the code or for any of you to do all my stuff for me, I'm just asking for direction and resources. Thank You

I can replace an axle as easily as a hard drive. I'm not afraid of getting greasy or soldering on boards. In other words, I believe I am up for the challenge Any help or advice you can give would be greatly appreciated. peace, Scott

Choosing components for a car-amplifier - which way to go?

Sci-Fi Contest Question

Hi Internet! I just saw the Sci-Fi Contest recently opened and I immediately had a bunch of ideas for projects, but I noticed that the contest page says "any project inspired by a film, TV show, or book is eligible." I was wondering, if I were to make something based on a sci-fi video game, would that still be eligible to enter? There's quite a lot of this genre in video games and I'm guessing other people will probably be interested in making video game-inspired projects as well, so I thought I'd ask just to be sure before I get too far along in a project that may or may not qualify for entry. Thanks for your time!

car, transportation, egg

Hi, i have to build a toy car or something like it, powered by rubber bands so its no problem, the thing is that it has to travel 31ft on a straight line, and then stop at 31ft and drop an egg. the egg must survive the fall from the car... Any ideas??? I'd consider using some type of braking mechanism. A string wrapped from a front axle to a rear axle would make a great brake. It would work kind of like a cassette tape; winding from one side to the other, and stopping when it's completely transferred form one to the other.

Portable car stereo

While waiting at a red light, I noticed that inside of a FedEx truck, the driver had his own portable car stereo in the cab with him. It consisted of a wood box with three 3.5" Dia speakers on the side with the stereo (what looked like an older model) sticking out of the top of the box, vertically. I'm guessing he had it wired for a cigarette lighter adapter to power the unit and the box was held in place in the cab by bungee cords. It looked like a great way to recycle old car electronics, wished I'd thought of it when I had to drive cross-country in a Uhaul with only an am/fm radio.

I did stumble upon an old episode of myth busters in which they came to the conclusion that a car can run on hydrogen, but they were unable to provide enough hydrogen from their electrolysis setup, however, I noticed that the HHO generator created by king of random produces way more gas then theirs. so I wanted to know your opinion and knowledge on this matter and whether this can work or not.

MP3 unit for car

Hi everyone, I was wondering if I could get some help with a project I'd like to make. My truck's stereo died, and instead of getting another stereo, I'd like to make a unit that just uses my MP3 player. Junkyard stereos are of dubious condition, and usually overpriced, and I'm too cheap to pay for a new stereo. I never really used the radio or CD player on the old unit; I just want basically a jack for a MP3 player/laptop, volume control, and power switch, powered by 12V and able to be hooked up to 4 speakers. I have some basic electronic knowledge, but not enough to make something like this. Could someone maybe, possibly, provide me with a diagram or ideas to get this started? Thanks a lot!

Powering a Wi-Fi router from USB

Hello guys! Few days ago I bought a Huawei B260a 3G Wifi Router (http://www.mobilityminded.com/6685/huawei-b260-3g-gateway-review-routing-a-cellular-data-connection). The power supply has an output of 5V/2A and is connected to the router with a USB B plug. In my car I have a Belkin USB charger with 2,1A output. So it would be nice if I could use the router in my car. I tried to connect the Router to a USB wall charger (5,1V/2,1A) with a standard USB A to B cable, but this didn't work. Furthermore I tried to cut the cable and connect only the black and red wires, this also didn't work. Somebody told me that the layout of the plug is different (as far as I've seen, at least the contacts match to the standard), can this be true? And is there a possibility to realize my idea of a hotspot in my car? Thanks for your help!

A week in a proper car.

I've been driving Womble for exactly a week now, and some things have occurred to me. I thought I'd share them, in no particular order.I enjoy driving again.Because I'm driving, not steering. No power steering, no servo brakes, I am in touch with what the car is doing every second I'm driving. I do something, and I get instant feedback. I'm suddenly redeveloping all the good driving habits I used to have - looking further ahead and watching traffic more, correct hand-position on the wheel, feeding the wheel through my hands as I turn, slowing with gears before brakes.It's a cliche, but it's seat-of-the-pants driving.I drove Kitewife's Focus a couple of days ago, it was a disaster! Taps the brakes, do an emergency stop - steer with two fingers, weave all over the road. There's no feedback, nothing to tell me by feel exactly how much braking I'm doing, or how fast the wheels are turning. I had to look at the dials to check the speed and watch the revs before changing gear.Modern cars, I have decided, are only one step short of video games.Maybe that's part of the reason for the rise in roadrage?There's no need to take pride or care, because the car does it all for you. Spend enough money, and the only thing that will kill you is if you drive at a tree. Even that may not be possible with radar-triggered brakes soon to become more common.If you have abdicated all responsibility for your safety to a mindless mechanism, who do you blame if something goes wrong? Where do you direct your anger? The only target left is the other driver.I seem to have joined a sub-culture.I'm not the only driver of a proper Mini in my area. I pass two or three every day. Amongst others, I've seen a white one, striped pink, with a bubbly blonde driving. I've seen a 70s Traveller in immaculate condition. Several jobbing Minis, in every-day-driving state, and a Mini wedged full of teenage lads, fully kitted out for racing, roll-cage and all.Every single one of them waved, flashed their lights or otherwise said "hello" as we passed. I have never seen drivers of other kinds of car do that. It's pretty good, getting a friendly wave from a stranger. It lifts your day, puts a smile on your face.It's like we share a happy secret. Minis attract comment more than cars that cost fifty times as much.If people see a Ferrari in the car park, they might nudge each other and make admiring comments, but if they see a Mini, they come over, say hello. On Saturday, a huge hairy rocker, returning to his big Japanese family car, children in tow, left his children in his car, and came over for a chat about the surprisingly roomy interior of my Mini, and an idle chat about the type of engine (single-point injection, if you're wondering).People might wish they could afford a supercar, but they are genuinely jealous of people who actually own a proper Mini.Everybody has a Mini in their closet.I'm not really a petrol head, and I don't work with petrol heads, but suddenly everybody wants to talk about cars. They all seem to have had an adventure in a Mini, their own or a friend's. Half of them regret having sold their Mini years ago.OK, so the old Minis don't meet modern safety rules. They're slow, utterly lacking in luxuries (my heater has two settings - on or off), but if somebody started building them new, using the original molds for the panels and frames (they still exist), and charged five or six thousand pounds a pop, they would make an absolute fortune.
