Chatty BB8 With Littlebits

BB8 from Star Wars comes to life. Walk past and he will try to strike up a conversation! This instructable uses LittleBits modular electronics. A motion trigger makes a speaker bit play BB-8 sounds.

You will need:

• Littlebits: usb power, 2 wires, motion trigger, mp3 player, split, 2 speakers, large mounting board, usb plug

• A printer/plotter (or good drawing skills) and coloured pens
• Craft knife
• Tape
• Cardboard and paper
• Computer

Make the image of BB-8. I found an image of BB-8 online and converted it to a vector file. I converted a Roland vinyl cutter to a pen plotter, and used this to print the outline. I made mine about A3 size. Stick it to cardboard, cut it out and colour it in. Make a hole the same size as the motion trigger in the middle of the image.

Make some triangular stands on the back of the cutout and attach this with tape to a LittleBits mounting board so BB-8 can stand up.

Find some mp3 files of BB-8 sounds online and store them on an SD card. Insert into the mp3 player bit. Take a look at the sound files attatched.

Assemble the littlebits: usb power → wire→ motion trigger→ wire→ mp3 player→ split → 2 speakers. The motion trigger is connected with wires so it can be attached further up to the hole in the cutout. 2 speakers are attached to increase the volume of the sound effects. Select ‘next’ on the mp3 player bit so a different sound is played every time it is triggered. Check to see if the sound is loud enough! You may only need one speaker.

Mount on the mounting board and plug into power.
