3D-Printed iPhone 5 Car Mount April 8, 2013 No Comments

We got a new MakerBot Replicator 2 at work this month. I had been meaning to print an iPhone 5 mounting adapter for my car, so I thought I’d try to print that using the new printer! The goal of the mount was to fit onto a car mount that I had bought for my [...]

BP Hobbies 25″ Flat Wing Foamie Build December 27, 2012 No Comments

Thanks to the Christmas break, I have finally had a chance to build the 25″ Extra flat wing foamie kit I bought from BP Hobbies almost a year ago. The electronics were purchased from Hobby King and include four 5.5g Turnigy servos, one Turnigy 1300KV motor, and one Hobby King 20A ESC. Control is provided [...]

Automatic Daily Fish Food Dispenser November 23, 2012 No Comments

Meet Bob, the goldfish (pictured below.) Bob is a pet at work, and we needed to keep him fed over the Thanksgiving break. I had an Arduino and a servo that were free, so I wanted to make something that would supply him with the right amount of food for the four days we would [...]

Legorov Teleoperating Robot November 8, 2012 2 Comments

I built this little robot out of Lego this week (see picture.) The electronics include an Arduino, a Sparkfun xBee shield, and an Adafruit motor shield. On the other side of the xBee shield is a linux box running ROS. With ROS I can generated velocity messages from my keyboard or with a Wiimote. These [...]

Mecanumbot Gets a New Body August 10, 2012 No Comments

After a few sleepless nights, I have finally milled out the pieces for my Mecanum-wheeled robot body. The outer and bottom body pieces are made out of 1/8″ G10/FR4 Garolite. The top two layers are made from transparent polycarbonite. A thin layer of transparent silicon will be placed on the top-most layer of polycarbonite to [...]

The Ball Bot May 4, 2011 No Comments

I’ve started a new robot project! This will be one of the most challenges personal projects I’ve embarked on. I have the following goals: designed to be a flexible software test platform mechanical design from scratch in SolidWorks, manufactured from G10 low level control through off-the-shelve electronics including an Arduino, SparkFun Quadstepper motor controller, ITG-3200 [...]

Flying Wing February 12, 2011 No Comments

Check out my new flying wing! The plane is made from a pair of EasyStar wing tips, a custom kevlar body (thanks Geoff!), and a handfull of electronics. The design is loosely based off of the AeroVironment Wasp. Below is a short video showing a few build photos and a recent flight set to the [...]

New Quadrotor Frame February 5, 2011 No Comments

I recently decided to update my quadrotor’s frame. This frame was designed in SolidWorks and cut from 1/16 inch G10. It has considerations for a GoPro camera, a downward facing ultrasonic sensor, ArduPilot Mega and Arduino (ArduCopter) boards, and much more. I’m pretty happy about how it came out. Let me know what you think [...]

Five Hour Plane October 19, 2010 No Comments

I few months ago I got the tiny Turnigy Slowflier from HobbyKing. The plane is fun to fly in confined spaces, but is pretty fragile. Well, if finally fell apart today and I decided to make a new plane with the electronics. It’s a pretty basic design as you can see from the pictures. The [...]

Grand Challenges LED Display October 6, 2010 No Comments

This year USC is hosting the National Academy of Engineering’s Grand Challenges Summit. One of my advisors at school has been putting in a lot of work for the summit, so I decided to make him this cool little display. It is battery powered and controlled by an Arduino mini. What do you think?
