Wireless Laser Bound Safety Perimeter

fi

For an engineering design course, we were taught the process of identifying a community, finding a problem in that community, discussing the problem with stakeholders, and proposing a solution to solve the problem. Of course, there was a lot more to it than that, but the reason I really enjoyed the course was because it was a great opportunity to experience the design process in its entirety. From finding a problem to building a working prototype of the proposed solution, the end result was very rewarding. My biggest role in

Meet Discovery – The Omni-Directional Remote Inspection Robot

fi

For a recent robotics competition, I created a robot which had to complete a series of tasks in a simulated disaster scenario. From reading gauges and picking up objects, to pushing buttons and deploying payloads, the tasks were very exciting. What made it really challenging, however, was the fact that the entire mission had to be carried out without ever looking at the robot or arena (directly, anyway)! There were no restrictions on the types of robots you could bring – so there were a lot of really creative designs

Smart Electronic Garbage Bin Locking System – ElectroBin

fi

A few weeks ago, I entered a small design competition with a group of friends. I was responsible for the prototype. Essentially, we had to design a mechanism for garbage bins (you know, those bins you place outside your house filled with garbage). Thing is, the garbage is actually an all-you-can-eat buffet for prowling masked rodents – a.k.a. raccoons – at night. So the mechanism had to be designed in a way which would prevent raccoons from creating a mess on your front lawn by toppling over your garbage bin

Internet Based Temperature Sensing System

This post will describe a project I worked on a few months ago during my spare time. Looking back, I see how much my skill set has changed, and how I would have attempted this project in a completely different way. Nevertheless, this is the whole point of documenting one’s work – and one of the primary goals of my blog (see About section). It allows me to keep track of my progress (i.e. see how silly/naive I was before). Parts of the following post were actually written for a

RepRap 3D Printer Plotting Test

fi

Today, I would like to introduce you to a 3D printer I am building. 3D printers are undoubtedly amazing machines, and the open-source movement has certainly left no stone unturned when it comes to these rapid prototyping ones. After having almost completed this printer, I have identified several shortcomings in its design, and am currently designing my own printer to share with the world – “innovation through iteration”, as I always say. For the record, the machine in the video is a modded version of the RepRap Prusa Mendel i2.

USB Mobile Phone Charger Using the L7805 Voltage Regulator

I have a really big problem: my phone needs to be on all day, or at least for 8-10 hours. I own a really old Android phone, and its battery only lasts a few hours at most now. You may be wondering why I don’t just get a new battery and solve all my problems. I have tried three times, and none of the so called “compatible” ones work, but I have another one on the way. In the meantime, I was left with no choice other than to come

Capacitive Touch Sensing Game Controller & Processing Game

fi

I really like my phone because of the way I can seamlessly interact with its touch screen – among many other things. Most touch screens nowadays utilize capacitive touch sensing technology (which I’ll explain later), so this project is my little way of exploring this amazing technology at a very rudimentary level. As you’ll soon find out, my project ended up going much further than I had initially anticipated, and resulted in the creation of a homemade video game which I played with a homemade controller and (you guessed it)

Transmitting Audio Wirelessly Through Light

fi

I love listening to, and playing music. I also enjoy playing with lasers, and using wireless technology! Why not combine these geeky interests to make my own wireless audio transmitter? You can wirelessly transmit music/data using all sorts of other technologies, but this project will utilize a portion of the visible light spectrum through a laser. This is a perfect project for kids wanting to clinch a science fair ribbon too. Wow the judges by using a laser pointer to transmit your favorite song from across the hall! I ran

Radio Controlled Parachute Drop

fi

Ever since I developed a passion for scratch building radio controlled airplanes about a year ago, I have been very eager to design a system to deploy parachutes and other fun payloads (I’ll keep those as surprises for future posts). Radio Controlled Parachute Drop from Treehouse Projects on Vimeo. I recently built an electric 41″ Cessna 185 out of foam, adapted from Mark’s plans over at www.budgetrc.com. He’s been a scratch builder since 1977 (well before I was even born), so he’s got a few more years of experience under

Accelerometer Controlled Robotic Hand

fi

This is my first post on Treehouse Projects, and I hope it will be the beginning of a lot more to come in the future. Prosthetic body parts have always intrigued me. The research I have witnessed and read about in the field has always inspired me to try and find solutions to assist people with disabilities. By no means is this project an innovative step in that direction, but it is a first for me, and I hope future versions will be much more practical and potentially useful from
