Froggy put on a little eye makeup before heading out for the new ride, "The Seesaw." The Seesaw is the third ride in the amusement park for adv...
Start with 3 inch wide (1/2 inch high walls) aluminum channel, 29 inches long.
Print the seesaw al bracket and attach it to the center of the aluminum channel with machine screws.
Add the seesaw cap to one end of the channel.
Add acrylic shields to the end and right side of the channel (these are to keep Froggy from bouncing out). I screwed one piece of acrylic on and I "w...
Using the balance base a, catapult motor c and catapult motor lid (printed 3d parts), attach the servo motor to "the tower."
Attach a 1 1/2 inch diameter, 7 1/2 inch long acrylic rod to an 8 inch by 6 inch by 1/2 inch (painted plywood) base.
Find a position "midway" in the servo travel and let the motor rest there. This way, when you attach the channel in a "mid travel" position; you'll k...
Pre drill holes in the top of the acrylic rod to accept the gear bearing holder.
Mount the servo horn to the seesaw al bracket, then mount the channel to the servo motor. Fasten the servo screw in the center.
The wood dowell (1/4 inch diameter) should fit into the bearing and slide through both holes in the seesaw al bracket.
It should look like this.
Fasten the gear bearing holder to the acrylic rod with a machine screw to fit your pre-drilled hole.
Take a 5 inch long (1 1/2 inch diameter) acrylic rod and saw one end to an angle that is similar to the angle of the aluminum channel when the channel...
Glue (superglue) a piece of sponge to the acrylic rod, then fasten the assembly to the base with screws.
Print the seesaw support and glue sponge into the cradle at the top. Attach this to the base.
Wire according to this schematic. Enter this code in the Arduino: #include Servo myservo; int start = 10; int next = 7; int val = ...
Adjust the "myServo.write" numbers to keep the movement "soft" and to reach the appropriate end positions.
To avoid litigation from "adventurous plastic attorneys," I built a caution sign--indicating what will happen if a frog sits on the end stop cradle.
Connect it to the last ride (The Boot) and let the fun begin!
