31.3. Goals¶
- Make the Krazy Kar.
- Don’t break anything.
- (Or if you break anything, learn how to fix it).
31.4. Materials¶
- 1 x Krazy Kar Shell
- 2 x Continuous Servos
- 2 x Wheels for Servos
- Some x Tape
- 1 x Basic:bit
- 5 x Screws
- 1 x micro:bit
- 1 x Battery Pack
31.5. Hardware Step 1 – Shell it!¶
- Fold up the cardboard shell where the line cuts are.
- Tape it such that the sides stand 90 degrees to the base.
- You should be able to slot the top shell (one with 5 holes) into the bottom shell now.
Step 2 – Put in the Innards.¶
- Insert the two servo motors into the holes at the sides.
- Behind the stabilizing rectangle is some double-sided tape. Peel off the paper and push the rectangle in between the servos to secure them in. Stick it down well onto the base!
- Fill the battery pack with batteries and place it in the front of the krazy kar.
Step 3 – On to the Outside!¶
- Screw the wheels onto the continuous servo motors.
- Thread the servos and battery pack’s wire through the rectangular hole in the top shell. And fit the top shell onto the bottom.
Step 4 – Upgrade the micro:bit¶
- Screw the micro:bit onto the basic:bit using the longer screws provided. Note that the holes should align, P0 to P0 and G to G.
- Affix the two servos into P1 and P2 of the basic:bit, making sure that the brown wires goes to G and the yellow wires go to S.
- Switch the P0/Buzzer switch on the basic:bit to buzzer. If it was already there – lucky you.
Step 5 – On to the Outside!¶
- Using the 5 screws, fit the micro+basic:bit cyborg into the 5 holes on the top of the krazy kar.
- Decorate decadently. And code it to get moving!
