or that plus:

This thread is glorious

or use this if you're lazy ($1 on ebay)

I always thought you need an amp for that to work? I never did a chipboombox because of that

cool, i've ever wanted to give a try to the car amp concept to make some punky DIY double-bass amp for our street busking with the band...

but i'm just a lazy thing, so I keep on ruining my fingers playing loud acoustic...

Yes! Nice setup!

I went through a kindof obsessive phase of building super cheap 12v soundsystems, sooo im gonna hijack this thread to show them off.

first one i made, £3 30W car amp and speakers from a bin, 12v recycled alarm battery

another one, £20 sure electronics amp 200W and some £5 car speakers from a car boot sale. in an old furniture drawer.

i found two really heavy 12 inch drivers and just had to build cabinets for them. got all the wood from a bin. i run them off a 300w car amp and old car batteries from a recycling centre. this is such a big & heavy setup, but i can just about fit in all in a bike trailer and cycle it about

one day ill get round to going busking with them & lsdj. chip street party ftw

looks like quite a lot of them will get tortured around the world in the next future

great tip!!!

yeas let the challenge begin!!!

I feel like this is a challenge to make the cheapest setups possible...

Whether or not it is, I accept.

You might need to disconnect the motor that drives the tapedeck and press down play to get it to work (sorry, forgot a step, i guess).
Basically it's a free STEREO practice amp, totally worth it!

Suddenly that fake old-timey stereo in the living room might have a purpose if my wife will let me crack it open...

You want CHEAP? You want OG?
Step 1: Go find a boombox with a tape deck, possibly free anywhere in the world.
Step 2: Open it up and desolder the tapehead, and also the headphone jack.
Step 3: Connect the wires that used to be connected to the tapehead to the headphone jack.
Step 4: Close that shit up.

Plug your GB into the headphone jack, crank it up, and busk while some guy breakdances, forever!

Im astonished by the existence of 8$ amplifiers. Should I build something for busking?

The craziest thing is this actually looks nice, too.

I'm surprised there isn't more of this sort of experimentation with different driver and amp circuits. I recommend making your own amp circuit from transistors instead of using an op-amp IC.
