Fiberglass build as opposed to wood. That's my 2cents!

Hi guys,

I've been working on a project recently that sort-of fits here.

Take one
Bose iPod Docking Station (Slightly Faulty) | eBay

Remove the internal electronics. All of them. The speakers inside are half-decent: no really low bass, but a bit of a peak before rolloff gives a decent impression of having low end.
Basically just find a faulty Bose sounddock. I got mine free as someone was throwing it out. A dead one is ~£50 over here.

Add one of
Mini Amplifier Board 10Wx2 Class D Amplifier DC 12V NEW | eBay

Power with, for example, a 7.2v RC car battery: commonly available, will run the speakers plenty loud - I use mine on the college playing fields: I'm told one football pitch width is the maximum range.
A decent battery will get >1.5 hours running the system flat out. Easy to carry a few around, so that's what I do.

Upgrade the battery etc as you wish, but the entire thing cost me (so far) £11. To do it again would be more like £80. I'd still consider it a bargain.

Chris

PS - the next step is to add some high capacity AA rechargables (there's space underneath) as a permanent feature, then work on taking out the low bass (cut pointless cone excursion) and boosting the highs slightly.

Hi,

The fundamental problem is the sound from the laptop sucks,
it does on nearly all laptops, and also apparently for a laptop
it is very poor, which means it must be bordering on painful.

Easy to fix, i.e. make loads better for next to nothing.

These USB powered speakers plug straight into a laptop,
do slaughter any laptop I've heard, they sound very decent,
come with a carry bag they can be put into for portability,
and are very cheap, not worth trying to build similar :

Simply auditory luxury compared to laptops, and small enough
with the carry bag, that you would take them with you travelling.
USB powered makes them as portable as the laptop on battery.
They will transform watching videos, and make music palatable.

Before I get bashed about by the hifi types, I've no delusions
as to how good / bad they are, they are just a lot better than
laptop speakers and sound a lot better than one might expect.
The speakers below are a big step higher, and worth it IMO.

rgds, sreten.

My laptop speakers are mains powered so not very portable, but good :
Computer Speakers - what you can get for 25 USD or 15GBP
