Make the Krazy Kar. 2. Don’t break anything. 3. (Or if you break anything, learn how to fix it). ## 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 ## Hardware Step 1 – Shell it! --- ![](./images/Dm0im8u.png) - 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. ![](./images/QFPRafF.png) - 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! ![](./images/jcbfc8r.png) - 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 ![](./images/FCBt2rx.png) ![](./images/QQX9HFg.png) ![](./images/rnX6e5B.png) - 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! ![](./images/36e1m2j.jpg) - 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!
