Week 5 Objectives:
Objective B: – Wire Motor
Objective C: – Construct Junk Racer
3 AAA battery Pack
2x M-M wires
Objective A: Battery Pack
Attach male leads to the 3 AAA battery pack that will power your junk racer. Instructions are in the video.
2x M-F wires
Objective B: Motor
Attach 2 M-F wires to a motor for your junk racer. This works with M-M wires as well, but they aren’t as long.
Strip each wire to about 15mm.
Twist the stripped end of each wire so that all the copper strands come together in a single point.
Twist a wire on to each of the copper motor tabs.
Be careful with the motor tabs – they are delicate and may tear if you tug too hard on them.
Wired AAA pack
1x Power rail
1x Popsicle stick
Objective C: Junk Racer
Use a glue gun and whatever junk you can find to build the racer body.
Start by attaching 2 wheels to your motor. Next, glue a popsicle stick to your motor so that you have a point to start attaching junk to. Afterwards the design is up to you. Remember to attach a power rail and a battery pack to your racer for building circuits.
Off-center weight or drag will steer the racer to one side.
Heavier weight will make the racer slower.
More drag will make the racer slower.
When the racer body is done, build your circuit using the diagram.
