Cookie Monster (Thursday Jan. 23)


COOKIEMONSTER

The Cookie Monster was really sad after going to rehab for his addiction to cookies. Much like all addicts cookie monster is freaking out because he cannot eat anymore cookies. It should also be noted that his fascination for Mario is so immense and deep rooted that you can hear their theme-song coming from his head!


Top: This is a H-Bridge, which allows us to move bidirectionally using pins 5(Direction) and 4(Motor).
Middle: Speaker connected to pin 8.
Bottom: A button which dictates when he can move.

Day 4

A picture of a completed remote controlled vex box bot.
A push-button controlling when the current touches the base of the transistor and when the LED turns on.
This is a video of how current is passing through my finger to the base of the transistor, allowing the LED to turn on.

Day 3

Using two Slide Switches to control an LED.
A push-button controlled relay which relies on a single-pole double-throw, to allow the LED's to flicker back and forth.
This push-button relay control works in a similar manner except now the button controls the throw, not when ground makes a connection. We also innovated a capacitor to allow the relay to oscillate and the LED's to flash.
The beginnings of my square-bot.

Day 2

A Picture of a few things we measure the voltage of.
This is a Light Dependent Resistor (LDR) meaning its ohms change with light and darkness.

A Breadboard with three lights each with a different resistor (100 ohms, 1,000 ohms and 10,000 ohms)


This is a video of 100 ohm resistor between an LED and potentiometer.

Day 1

This is a picture of my first time soldering. First we used flux to remove any oxidation. After soldering and clipping the wires we used isopropyl alcohol to clean the reaming flux off the board.

Next, we practiced soldering wires. First we removed the insulation off the wire then carefully put the wires side by side to solder them. Finally we added shrink tubing to properly insulate  the joint.
A picture of an ac adapter that we soldered.
