This miniSADbot was created for the Kickstarter backers who supported the original SADbot exhibit
that Ben Leduc-Mills and I created. Thank you! Here you will learn what to do with the kit of parts we sent you. If you didn't back the project but still want to make one, a full parts list is included. There's not much to it so it's an easy first solar project.
Step 1: Gather materials
small DC toy motor like the CAT# DCM-368 from AllElectronics.com shown here
small solar cell like the CAT# SPL-61 from AllElectronics.com shown here
some wire - ideally red and black
a 4.5" x 4.5" piece of cardboard
2 markers or pens
You'll also need a soldering iron and some solder.
Step 2: Solder wires to solar cell
Use tape, glue, or putty to hold the two longer lengths of wire (red and black) onto the thin metal strips on the back of the solar cells. CAREFULLY solder each side - the strips are very fragile! The black wire goes on the side marked - in black permanent marker, and red on the other.*
*It doesn't actually matter what wire color goes where in this case. However, it's standard to use black for negative/ground/- and red for positive/power/+ and will matter in other solar projects. So, it's good to get in the habit.
Step 3: Solder wires to motor
Take two short lengths of wire and solder them onto the metal tabs on the motors. Use the holes in the tabs to first stick the wires through and bend them so they stay put while you solder.
Step 4: Create the base
If you're building this from the kit, you already have the base done. If not, use the template here (made in Inkscape) or just cut a 4.5" x 4.5" piece of cardboard with X marks for the pens/markers and a cut out for the motor.
