Physics Project

I'm making a frictonless rail for a physics prject. I will program the arduimo to be a timer. pics when I'm finsihed.

Arduino

Working on a Snake game using the arduino and LED Matrices. :]

Solar Cup

Solar Cup is a seven-month program that begins in the fall, in which high school teams totaling about 800 students build and race solar-powered boats at Lake Skinner, in Temecula Valley, learning about conservation of natural resources, electrical and mechanical engineering.... read more.

Arduino Theme Songs

The Arduino library came with many themes songs built in. I will post a video soon of them all.

Attempt of Motor Control

The chassis and gear box belonged to an old RC car that didn't work. Right now it has no input devices and can only run a simple forward backward, left right program.

TV BE GONE

So this device turns off all TV's around it. It works great! Ive managed to turn a lot of different TV's off and i haven't encountered one i cant.  This is called a TV B Gone. There is a tutorial in adafruit's website: http://www.ladyada.net/make/tvbgone/solder.html

Though they do sell a kit, I suggest buying the pcb and the IC only and using your own components if you have them. But if you don't have these parts, I think that the kit is the best way to go.

Motor Control with a SN754410NE

Thanks to the people at ArduinoFun, http://arduinofun.com/blog/2009/10/25/duel-motor-driver/, I was able to make the motor driver work. Here are a few pictures.

IR Camera Control

I used the C code on http://www.bemasher.net/archives/114 to trigger my Nikon camera remotely from my computer. I could work on this code to make something cool. Thank BeMasher!

New 4 Note Laser Harp

This is a new prototype of my laser harp. I let the beams shine through a colloid.

Laser Harp Video

Laser Harp With 3 "strings"

This is my laser harp. Just a prototype of a prototype.

Video will be added soon.

Laser Trip Wire With Speakers

The same thing but now when the laser is broken, an alarm goes off. 

Laser Trip Wire

So I made a laser trip wire for the Arduino.
I got the idea today since I went to the 99 Cents store and picked up 3 lasers.

Here are the pictures. When the laser sight is broken the LED turns on.

Work Bench Jealousy

This is the work room of a member of the arduino forums. Wow, this is epic. The work bench is huge, and the shelf seems to have everything! Must have taken months to collect all that.

Arduino Piano

My next project for the arduino will  be a small piano like device. I'm still a little fuzzy on how to do it, but probably in 2 weeks  I'll have a prototype.

Sentinel Video

This is the video of my robot.

Robot 2.1.2

This is my fully functional robot with its new circular base. It avoids walls and obstacles like a pro!

This robot just gets better and better.  Leave your thoughts in the comments section.

I also added an LED to the robot to show when it sees an obstacle. (not shown in picture)

New Base of Robot 2

This is what I'm up to in the next improved version of the robot. I'm making the base circular.

Version 2.1.1 New Steering

Well I decided to take off the front steering servo. I did this for power consumption and because it requires the 2 driving servos to push forward so it can function. The new way of turning is to have one of the wheels move in opposite direction of its partner. This is more efficient because no time is wasted going forward and it moves around faster.

With this new concept I can create a cylindrical shaped robot... R2-D2

Power Supply Problems

Well, With my Robot I ran into a few problems. This is actually very good news.
I can now improve my robot. The new robot will feature 4 battery packs. That will make it heavy but it will also improve speed, torque, and play time!
Currently I hooked up 2 of the driving servos to their own 4.8 volt battery packs. This helped a lot, but the steering servo and sonar are still using 5 volts each out of the Arduino which is only powered by a 9 volt battery.

Things don't function that well when the power source is low. I hope to improve the chassis by adding a better look and maybe make it enclosed. This will be V2.2.

I also improved the code that the robot runs on.
