Arduino Sketcher

Introduction

I had gotten a joystick a while ago and wanted to do something different and interesting with it. After coming up with and discarding a bunch of other ideas, I came up with the Arduino Sketcher. The ideas was to make something similar to an Etch-a-Sketch but uses the joystick instead of two dials. The computer would serve as the sketching pad while to Arduino relayed all the commands sent by the user. This project uses both Arduino and Python and turned out to be fairly simple to implement.

Simple Security System

Introduction

Who hasn't wanted to monitor what goes on when they aren't there. When I was little, I was always curious about whether or not anyone was going into my room and would have loved a camera monitoring system. It may even be a good idea to have a simple security setup for an apartment.

This tutorial shows how to set up a PIR sensor along with a small TTL camera and an SD card to capture images whenever there is movement in the monitored area.

The necessary libraries are: SoftwareSerial (for the camera) and SDFat (for the SD card).

Divergence Meter

Backstory

I want to make a divergence meter. A divergence meter is not a real thing. It's a fictional device from Steins;Gate to tell if the worldline (timeline) has changed substantially from an original world line (the alpha) - following the time travel theory popularized by John Titor. If you've never seen the show, you might still be interested in how to wire up a longer string of displays to get 8 digits instead of being stuck with just 4.

Octobot Chassis

Introduction

Octobot is the name of the robotic chassis that I do most of my testing on. It got it's name because it originally had eight wires sticking out because of the motors.

The picture to the right shows it in its unfinished form.  The front two wheels were removed and exchanged for a ball caster for manuverability. 

Once completed, the chassis makes an excellent inexpensive platform for an Arduino robot.
