The Boominator - another stab at the ultimate party machine

I've tried measuring both with reversed polarity and normal polarity. In both cases I get around 20k Ohm.

I would have guessed that a diode would almost always be in included in retail panels. It's not something I bought off eBay anyway

Anyway, would this diode be suitable?

I was planning to build an boominator with 12" HP-12w, but I have no layout. Anyone who can send me some layouts for 12" instead of 10"?

The HP12W cannot be used. The parameters dictate a roughly 80 liter minimum cabinet size per side. It would mean it would have to be more than 3 times larger. Also the HP12W is a sub driver that does not sound well over 400-500Hz, so you'd need a midrange driver as well.

I know i have read it before in this thread but cant find it...!
What kind of glue should i use to attach the solar panels on top of the boominator?

It is a metal frame (aluminium?) on the solar panels.

Does anyone know a formular of how many amps a solarpanel with a X number of watt gives? Im looking to buy a 30w panel (i wants a seperate one.. not one on top of the boominator) So i would like to know how much the panel will charge on a fine sunny day at Roskilde (festival)

I (current) = P (power) / V (voltage)

There is a billion pages and since the introduction is 5 years old I was wondering what changes(if any) you would make today.

Some of the pictures on the first page with your instructions, aren't working, so I was wondering if you could upload the page again or something smart?

Because I really want to get started and I guess I really need to start figuring out how to get all the parts ordered soon, if I am going to make it before Roskilde Festival starts.

Best regards,

Audacious.

There's a recap post a couple of pages back by aaroe.

okay so with a 30w solarpanel its = 30/12=2,5a? sound quite a lot :b the battery 's limit is 1,75a for recharging, but i guess the chargeregulator can do something about that?
