The Boominator - another stab at the ultimate party machine

[LaserTorsk]

That's a slammin' deal. Buy a few and see what happens.

I'm too scared man

 

[gmarsh]

Two possible outcomes:

(1) They say "oh, we made a mistake" and cancel your order.
(2) They sell you a few panels for an awesome price, you resell them to others and easily make your money back.

Any ideas why this might be so ridiculously cheap? Most amorphous 15w panels cost like five times as much...
14W Solarmodul 12V System - 10140 Koekraf Alternative Energy
I wont mount it, i'll use it externally instead.

Thinking of getting a solar panel instead of three batteries. I guess three batteries wont last the entire festival anyway.

I've just bought four of these 81.50 euros including postage to the UK....

I hope its not a scam, but I thought it was worth a punt.....

Hmm... Just noticed that Koekraf email address is a hotmail address.... not a good sign

Cant wait to see what happens with those solar panels !


Just want to share my filters for the mini! Wesley put it together for me!
Very nicely done! Cant wait to put the things together!

Thinking of bringing this to the festival for the boominator mini
Amorf solcellemodul MR-ASP-10W/24V med SORT ramme, KeryChip WEBSHOP - solceller, solcelleanlæg, tilbehør

and this regulator

Solar Panel Charger Controller Regulator 10A 12V 24V Auto Switch CE TSR Safe He | eBay

would that work and what would need to be done except for just hooking up the devices? a led of some sort?

given that it is fairly sunny and the mini playing 10 hours a day how much battery would actually be used with a 10w solar cell? 7.5 Ah sla

What type of board were the xo made on? Ive seen them in a few photos but have never seen a source.

 

[Silas K]

Pretty sure it's just a blank DIY curcuit board! But for further info ask Wesley

Alternatively just ebay curcuit board.. There's loads for Cheap

 

[WesleyK]

I used 2 of these:
RE525-HP - ROTH ELEKTRONIK - PCB, EUROCARD, FR2, 100X160 | Farnell Nederland
With a few of these:
63849-1 - TE CONNECTIVITY / AMP - TAB 250 PCB 032TPBR | Farnell Nederland

Works quite well as the terminals just fit(with a hamer ) the larger holes on the side of the circuit board

 

[aterren]

Ah, I thought it was purchased with the terminals. Clever solution. I even have the right tools to do this (hammer).

still no word from Keokraf, cant pay by paypal or bank transfer, it had to be too good to be true, worth a punt tho. I don't think that Koekraf are legit. but I haven't lost anything.

I read about koekraf on some swedish forum, and they were all happy to buy solar power for "german prices" or something. I actually think it's legit but this is very very weird

The fuse is there and must be there to protect own, and those around you's life and safety. Should something short circuit the batteries could heat up the wires and catch fire. Burning not just your boombox but potentially killing you as well if you have it in your tent while you're sleeping off last nexts binger.

Also please note that no insurance company in the world will cover any damage you may cause by not having a simple $1 fuse. A 10A in-line cable fuse meant for car audio is fine. Don't use 2A fuses unless you want to change it every time you turn up the volume. The average power consumption is 0.35A. But peaks may be up to 5A.

Shorted batteries tend to go pop. Even the small ones will put shards of metal out in a 5m radius.

I wouldn't want to be nearby if a lead acid battery got shorted. There's a lot of energy there - I wouldn't expect a tiny confined box to hold it, either...

Does any of you guys know anything about the ND16FA here i Europe? i can see that intertechnik will have them in 65 days, over in the US parts-express says 10/06. I can't find any information from accusafe, but if there are any other places who might have them, i'm very interested

 

[WesleyK]

I (accusafe) will most likely be able to get a new batch the 10th of June, so that won't take too long anymore. I hope dayton made enough this time ;-)

Hello first post here, im planing to build my own Boominator and i am going for the standard design with 4 hp10 and amp6... So to my question I am thinking of have a switch to turn off one side of the box. ex. If you are in a place where you do not want sound on both ways. Do you think it will work or will the speakers that are off will take beating when the other side is playing?

 

[aterren]

I am thinking of have a switch to turn off one side of the box. ex. If you are in a place where you do not want sound on both ways.

This is not recommended because speakers play in both directions at all times. This would also change the box performance by effectively adding 2 passive radiators and that is a different box design.

Plus the fact that you'd end up running 8 ohms instead of 4 so volume would be considerably lower.

Ok, thanks for the info!

 

[Abeee]

So anyone that has the amp6 rev 1.20 assembly instructions?
