Firefighting Robot

For my project I created a robot with an attached water cannon. My mentor and I built it in a budget of around $300 (not including the necessary equipment), and it functions quite well. For the motors we used drill motors, powered by the 18 volt drill batteries. To control it all we used an arduino microcomputer. Step 1: Make Parts List/Gather Materials It is crucial that before you start a project, you kno ...

An animation inside a water drop by Physalia

2000 pictures compose this piece- that is, 2000 perfect different water drops into which we mapped an animation. Droplets that behave and look strangely similar at the stage of less entropy, and become more disorderly as they splash. The final result of the piece you have seen has absolutely no CGI, and was shot in stopmotion so as to be able to project inside the waterdrop the logo formation, previously an ...

PuttDuino putt-putt hole with Arduino

My company has annual events where we all get together for fun - to blow off steam and have a little competition. In the past we have had softball and bowling competitions. This year someone had an inspiration: each department would build a putt-putt 'hole' in the officed and we would all compete to make the best hole. There were some amazing contributions. This is my contribution to the IT department's hol ...

Temperature Wand using Arduino

Most of you have heard the expression ‘Hot Air Rises’. Well, it’s true. So in your typical house, it’s going to be hotter near the ceiling than near the floor. How much hotter? Well, being a Lazy Old Geek, I wanted to know how much. Well, that’s easy, I just point my IR thermometer (See picture) up in the corner and down at the floor. Okay, it reads 82 F at the ceiling and 75 F on the floor. All done. But w ...

Arduino Alphabet

This project is very interesting because it shows the sequence of all letters of our English alphabet. That is, the project generates capital letters from the A to the Z based on Arduino code and showed by an alphanumeric display.  I'm using a common cathode alphanumeric display and an Arduino Uno in order to constructing this project.   Use the following link so that watch a video of the project working: h ...

Arduino based Tic Tac Toe with TV Remote

This was my first time attending the Internet of Things Pune Group. It was such a fun learning experience! At today's meetup, Dhiraj and Nishant started out by introducing the InduinoX and Arduino Uno boards along with the Processing IDE that is used to write the code. After playing around with couple of sensors on the InduinoX we thought of doing a micro project together and finally settled on doing a Tic ...

K4S, a Keyboard for Arduino to use with Scratch

This project starts a few months ago. Juan Brito, author of the blog Desafio Ecuador, contacted with me to talk about Scratch and the opportunities that gives this programming enviroment in the world of education. In his own words: I and Danny Macancela are convinced that increase the quality of education in schools and colleges do not require big budgets by governments. This ideal of change has led us to d ...

Arduino-powered A-10 stick grip remote w/Emergency Party Button

I came across Plama2002's "Emergency Party Button" build a while back and wanted something similar for my bar. I also had an old USAF B-8 stick grip from an A-10A that I picked up in my previous life. I figured instead of just being a conversation piece, I could put it to good use as a remote control for my AV system. What I came up with is a master control box that: - Controls my SAT TV, music server and i ...

RaspiDuinoRover – (Yet another) iPhone driven moving Raspberry Pi and Arduino rover

Architecture RaspiDuinoRover is made of three main parts: A Raspberry Pi which receives commands from a remote device through a TCP connection, and sends these commands to an Arduino Uno through an I2C connection. The same TCP channel is used to send back the remote data grabbed from the Arduino Uno about pan and tilt servo positions, camera lighting status and motors current usage. The Raspberry Pi also pr ...

Twitter garage door using the GE Choice ALERT system & Arduino

You know that feeling of driving away from your house almost getting to work and saying "Now Did close the garage door?" .  I hate that feeling and seeked out to resolve it in the smiplest/cheapest way I could.  The starting point was of course Arduino.  This project ended up being simpler than I could of imagined but it was not my best effort (as it was my first real project making something useful with th ...
