Yup. You can do that. Check both your panels with a multimeter. They should show some resistance in one direction, and no connection in the other. If that, no problem. If not, then you need to connect (schottky) diodes to your panels first, so the power doesn't just run into them and all you have is a really expensive space heater.

Hey,

If I can't find stock of the P.Audio HP10Ts anywhere is there a good substitute that can be found in the EU for a Qubinator build?

I'm planing on painting my boominator matte black ( "Mattsvart" in swedish ) and im woundering if this is gonna be a problem since the colour absorbes heat? If it's playing in the summer sun for a whole day, doesnt it get extremly hot in the electronical department since the batteries are there aswell??

If the heat will become a problem, how do i solve it? Havent started the build yet.

We're not living in Death Valley or the Aussie outback. It'll not be a problem.

Default Boominator test

Woo, just had a great weekend, two boominator partys, field testing my unfinished boominator.......

Check out Whitstable del mar....

Keams Yard de la mer - YouTube

and

Whitstable boominator party - YouTube

Ambience - Whitstable sunset, beer and peeps

Music - DJ - OzTvc
BJ's Boominator

Lots of glowing compliments about the sound quality
Offers to buy from rich Londoners down for the day
Suggestions to "patent" the design... all sorts...
Don't worry, I've been proud to say that I belong to a global open access community and that the design is down to a very clever Dane known as Saturnus.....

Input vol a bit low, will be sorted with the AMP6, laptop batteries ran out well before the Boominator... Volt meter reading 13.2v in full sunlight, hasn't dropped below 12.5v after 15hrs of playing..... seems like everything is working OK...

Whitstable is looking forward to a new way of partying, thanks Saturnus....

I'm already thinking of the next ones.... A pared down, bullet proof basic one with no solar, no voltmeter (just charge socket), on/off switch and input. It will have a built in satellite tracker. I'll hire this one out for other peoples parties.......

The other personal one will definitely be 24v, AMP9, mini DSP... can't wait to stack them all up and run them as a line array....... lol

To elaborate on this. If you're planning to take your Boominator into areas where day time temperatures can and will exceed 40 C (104 F) then it's probably wise not to paint it black. But the speaker itself and the amps inside are convection cooled by drawing cold air through the venting holes from near the ground and expelling the hot air at the top.

If you're running at 24V and full throttle during day time then you might wanna install a (temperature controlled) 60mm fan in the two top venting holes just to make sure it doesn't overheat.

Thanks for the praise, and thanks for sharing.

It shows exactly why I made it in the first. So people can have a good time. The boombox doesn't take center stage but just provides the musical experience to complement and amplify the mood. That's what a good sound system does in my opinion, simply melt into the background because the sound is clear, transparant and controlled.

Naturally ambient music, or any type of music that is heard rather than felt, is going to play to the Boominators strong points.

AMP6 arrived today, no paperwork with it so I don't know if the boominator mods have been included or not, I did message 41hz to say that the order was for a boominator..... My problem is that I don't know if the resistors and caps included are the right ones or not... also there are a couple of surface mounted components that I wasnt expecting... ah well, here goes......

The surface mount components are, IIRC, quite easy to do.

My approach was to apply solder to one of the pads (this is for the power diodes underneath), sit the component on the pad, heat the pad so the solder melts, wait for that to solidify and then solder the other end down.

Don't tin both pads, or it'll never sit flat to the board.
