This is the modification of a men's shoulder bag to add an animated LED logo using a BBC micro:bit computer. I am a journalist (I keep journals) and a geek and wanted a new bag to keep my journal and supplies in when I travel.
The UK government is giving all level 7 (middle school) students the BBC micro:bit miniature programmable computer to learn coding this year. My employer, Microsoft has been helping the effort with software tools for kids to use to program the computers.

Step 1: Got Bag
Step 2: Design and Print Mount
I designed a mount for the BBC micro:bit using the Microsoft 3D Builder software that comes with Windows 10 enabling me to insert the device and mount into the space between the leather front of the bag and the canvas lining behind it. I printed the mount on a Dremel 3D40 Idea Builder 3D printer with PLA and supports enabled.

Step 3: Alter Bag
I cut a small slit in the back canvas of the bag's front flap, large enough to insert the mounted micro:bit in. I then reinforced the opening with Duck tape.
Using a template, I cut out holes for the LEDs, mounting holes, and buttons with an Xacto Knife.
Step 4: Code micro:bit
- Left button slows the speed of the LED column
- Right button speeds the speed of the LED column
- Tilting the bag up changes the animation to Up arrows.

Step 5: Mount the micro:bit
- Place the micro:bit in the mount and insert both into the opening in the bag front flap between the leather and canvas.
- Attach USB cable to micro-bit.
- Push the bolts through the mount and leather and screw the acorn nuts onto the front of the bag.
- Attach the USB cable to the USB battery pack
