Mini Progress
While this thread isn't a build log I thought folks might be interested in a few things I am trying with my mini build:
One thing I have struggled with is finding a reasonable way to mount electronics so they are serviceable. I decided to try recessing 8 magnets into a center brace.
I will mount the PCBs to steel bolts and then let the magnets hold them in place. If this fails I will just use double sided tape.
Here it is in place:
A lesson learned from my NS6 Mini build is to use the tools I have and make the joints interlocking. It isn't necessary but it sure makes assembly alignment easier.
Here is my front / back plate. They are the same except the back does not have holes fr the mini jack and volume. In the corners you can see where I spotted the mounting holes. There are two more on the other side.
And placed on the front baffle. I will paint the wood behind the cooling slot black. Hopefully it won't be too obvious that the cooling hole is very small in comparison to the slot width.
I still have a lot of work to do but it is progressing.

I always love to say detailed build logs on here, so keep up the work 🙂 The more pictures, the better. Very cool way of mounting the PCB's. Isn't it easier to get your BT output from the RCA?
What RCA? 🙂 They were removed for space reasons. What I might do is solder directly to the PCB to eliminate the often unreliable 3.5mm connector

That's what I meant 😉 Solder directly to the PCB where the RCA's first were, you can tie ground together.
Hello guys!
For most of you is this, i think, a very stupid question but i'm not that good with speakers.
My question is:
i want to build a boominator mini or the normal version, but i don't know which speakers i should use, which amp, a separate filter, or how to make a the box perfect so i will have the best sound with the least battery usage.
I was thinking about using the Maxamp amp: Home - Maxamp 12V Versterker
And this speaker and filter set: Kistradio en Kratradio Specialist - Complete Sets - Boominator - Boominator Mini Speaker en Filter set
Do you think this is good for a boominator? I already have a accu, a adapter to charge the accu and the rest.
Thanks if you could help me!

If you want to make the Boominator Mini, yeah that's the good kit/set. You can build the normal one too, but it's more expensive and 8 times larger. Of course it will be much, much louder.
Accu=battery 😉. Which one do you have? Big chance that it might be too big for the Mini.

i have this accu: Kistradio en Kratradio Specialist - Accu's - Loodgel Accu 12V 12Ah
do you think that one is too small, too big or just good for this project?
do you think that one is too small, too big or just good for this project?
but can i still use it, so that it will work longer? or doesn't that work, because than the case would be too small for the accu?
sorry for my grammar, i know, it's not the best, i'm from the Netherlands 🙂

You can extend it, but it's just pure overkill. Rule of thumb: for every amp hour (Ah) you can play 2,3 hours on full volume or 10 hours on medium.
If you want to talk about this in Dutch you can join the Krat en Kistradio topic on Tweakers. There is a lot of talk about the boominator there too, and people who already build one.

Hello boominators
I've been following this thread for a couple of weeks, read it through and re-read. I think I've understood most of it so I've taken the plunge, bought a maxamp20, ordered speakers and started planning the cabinet but already run into my first problem.
I have a raspberry pi and an iqaudio dac running squeezeplug as my input but when I power both the amp and the pi from the same battery I get a lot of interference. It sounds like you can hear the pi running through the speakers, after a bit of reading I think may be ground loop interference. Any advice on how to eliminate this issue? At the moment it works fine running from separate batteries but I'd prefer bit to have separate power sources.

Thanks for explaining it! I think i will just keep the accu that i have at the moment
Most systems suffer from this issue, a good ground will fix this in most cases. I also used a DAC(volumio) for the Raspberry Pi, and this also resulted in a much cleaner signal.
Try to use a star grounding scheme, with thick enough wires.
Like in this picture:
Its a bit hard to see but if you look closely you can see that each grounding wire goes to the same terminal block, so every device gets its ground from the exact same point/level without being able to interfere with each other.
How are you powering the Raspberry Pi by the way?
Wow, that's some impressive work there WesleyK, makes my birds nest look a little embarrassing.
As a quick and dirty experiment I just took the ground from the pi and the amp to a terminal block and onto the battery, which didn't change the interference.
The raspberry pi power supply is a rc helicopter 5v step down which I've just crimped to a micro usb lead don't know if this would have an effect?

No kidding! If you want to feel better (at his expense) ask him how many hours of listening he has enjoyed on is flagship Boominator. 😀
Sorry Wesley, I couldn't resist.
What are the 2 gizmos at the top of the case pointed toward the power button. Quick connects for the drivers?

Could someone please post a blueprint of the case of the boominator mini/boominator?
And can i buy somewhere a pre-made set with the wood that i need for it?
Thanks,
Matthijs

I don't know of anyone selling a pre-cut kit (often called a flat pack) but it has been discussed a number of times. This is a DIY project not an Assemble It Yourself. I certainly don"t want to discourage you. To the contrary you will find it a rewarding build and you will certainly learn a lot.
Hey guys, it's me, again... hahahah
I have a little question: at the moment i have my own made boombox with a car stereo built in it, but if i connect my laptop with it it goes much louder than with my iphone.
I heard you could fix this really easy if you have a amplifier but can i also mod my car stereo somehow so that if i connect it with my phone that it will go louder, like with my laptop?
Thanks if someone could help me!
