The Blinkenschild 2.0 is powered by portable battery packs.

Today 4 strong battery packs arrived in the mail.

I had some leftover usb connectors form another project that i soldered into POWER cables.

Each 16x32 panel has its own usb attached power supply and the GROUND rail was connected on all boards.

I also have a dedicated batterypack for the Raspberry Pi.

So far so good.

The twitterscript is running for one hour so far, the leds are bright and the whole setup appears to be stable enough.
The only thing that worries me a little is the Raspberry Pi that complained with an undervoltage warning earlier.

I might connect a second usb cable and merge those for the power supply.

The cabling went better that expected.

I used zip-ties and shrinkwrap on the cables, the picture looks much messier than the real life outcome :)
