As Sonos has officially announced its mobile speaker Sonos Move today, many rumors about the hefty price tag have been confirmed: USD/EUR 399.- is not a bargain.
So I tried to make a cheaper version of it. Let’s say around 110.-. I took a Sonos Ikea Symfonisk, some already available Sonos hacks, a step-up booster and tools and stuff laying around at home.
I don’t have the skills to do things like that. But I’m not afraid of trying things…
Right now I am having problems with auto power off of newer powerbanks. While booting the speaker needs to less power so they turn off. I have solved it by using older "stupid" powerbanks or by leaving the power cable in the speaker until I have started music - then I can pull the cord.
Update<:/strong> I know have now ordered the Mi Power Bank 2S (Amazon affiliate link) it has a low power mode to charge small gadgets - it perfectly works now.

Just follow this guide.
Solder the two cables on to the circuit board. The red cable is the positive (+) contact. put the cables through the hole next to it. For the cables I used the other half of the USB cable where we will need the plug later.
Drill a hole into the case. I used a 4mm wood drill - but this depends on how thick your USB cable is.
Use the right length of the USB cable so you can store it in the back when you don't use it.
Fix the USB cable from the inside with a zip tie and cut off the end.
Optional: As I had a yellow shrinking pipe laying around I used it to protect the cables coming out of the circuit board - without shrinking it.
Solder the USB cable to the booster. Red is positive (+) again. I use this Step-up Boost for less than EUR 5.- (Amazon affiliate link).
Solder the two cables on to the circuit board. The red cable is the positive (+) contact. put the cables through the hole next to it. For the cables I used the other half of the USB cable where we will need the plug later. I use this EUR 12.- digital multimeter. (Amazon affiliate link)
Solder the Step-up Boost on to the cables running to the circuit board.
Use a hot glue gun (Amazon affiliate link) to fix the booster in the case. I also used some glue to fix the antenna cables to the board again.
Connect your power bank and fix it with velcro on the back. Sorry, had only white one. Next time I will use this (Amazon affiliate link).
