In the eighties they had the Ghetto Blaster which was pretty cool for the time. But most Ghetto Blasters produced today is sorta crappy and not really built for outdoor parties as they where originally intended. So when a couple of friends and I was going to have a party out in the open for around 70 people at Roskilde Festival 2009 I decided to go a bit further than your average Boom Box. This is a short describtion of the journey to create the DOOMSDAY DEVICE!!!!
We started out by having a used car battery from a 90’s Citroen Berlingo Diesel. That was going to be our power source and the goal was to get as much sound and actual play time from the setup. I don’t know much about electronics but luckily a good friend of mine does. I managed to poke his childish curiosity, his creative gene, a bit of mercy, and he joined the project. I know now that I would never had finished it without him.
This is the finished device.

Here’s a few steps from the building process:

A brief discussion about proportions and location of things and we started to cut things up and putting it together.

4.30 in the morning the device is finished and we drove it to a desolate place where we could test it's power. Never heard Creedence Song with John Fogerty that loud that early before. We where tired, but very pleased that it kicked ass.

Everything has to be black. We agreed that it needed flame throwers. But that will be a future upgrade.

Last minute tweaking and checking how the LEDs and indicators looks in the dark. Pretty sweet, yet simple. We knew it had to have some ludicrous lighting of some sort.
The Doomsday Device played for 4 days almost day and night and often close to max volume, without recharge. It even played a couple of days afterwards in my workshop before I was bothered to plug the built in battery charger to some power.
I might way a ton, but you can take your factory made ghetto blaster and showe it. Because here comes the Doomsday Device and it aint breaking for nobody.

Cool….looks like an old Fender guitar amp, more than a ghettoblaster. So no sub?
What electronics was used?
