Jaeyoung Lim Overview A USB2PPM interface was developed which enables a PC to interact directly with the RC transmitter trainer port. External Position Control was successfully demonstrated to show that the computer can successfully control real-time applications using the USB2PPM controller. This can be used for sending simple data in long distances (~2km) in a…
In this project, I’m making a Tablet PC with a Raspberry Pi with Raspbian and a LCD Touchscreen display. I bought a LCD Touchscreen from chalkboard electronics. Before designing the tablet, I had to set up the touchscreen. The biggest problem that I had was the power output of Raspberry Pi’s USB was smaller than…
This is a “Sound Visualizer”. I made this program for fun using Max MSP and Processing. Max MSP detects the sound and Processing draws some cool graphics. Enjoy the Video! Features – Sound Visualizer is consist of two programs : Mixer, Sound Visualizer. – You can set up Threshold from Mixer : Sound Threshold and Line in Threshold. – It…
This project started out as an experiment. The idea was that standard flight controllers should be able to control non-planar shaped quadrotors as long as the control board is mounted near the center of gravity. I decided to try the idea out. The project addresses the symmteric / non-symmetric forms of non-planar motor layouts. Basic…
I and my friend Jaeyoung tested GPS Autonomous flight mode of APM with two quadcopters which embed APM boards.
One embed APM 2.6 board and another embed Pixhawk board. Both uses ArduCopter firmware. A mission of Auto-flight is taking off from launch site – moving to waypoint – hovering for 2 minutes – returning to launch site.
A new flight mode was implemented on to the modified Arducopter firmware that is capable of maintaining constant yaw rate while the quadrotor is able to be controlled by the pilot in respect to the inertial frame. Such a flight mode can be used in localization applications (SLAM) or imaging. Sensors that have a narrow…
After we made Zipcar, we though about expanding this system. Current Zipcar system is working with radio signals, but I wanted to make system that works on internet. So, first work is to make video streaming service that works on internet. Hardware: Raspberry pi, Raspberry pi camera(this is not webcam) If you search on…
Post written by Jaeyoung Lim Project by Jaeyoung Lim, Keunwoo Park, Dongho Kang Overview The Zipcar was an experimental project towards a more instinct interface from the conventional RC stick based interface for FPV driving experience. A racing wheel for gaming was used to control a remote control car providing onboard first-person-view(FPV) Video and data…
This post is by Sungmuk Im. Overview This is a “Drum Sampler”. You can make your own beat. Everytime you press the buttons, you can see the cool interactions. Try hard to be a good producer! enjoy the video! (Special Thanks to the team mates 박나연, 정보람, 최윤정 of ITCT, SNU) Features There are 4 modes ;…
Recent attention to FPV racing and FPV experience shows that visual feedback from a teleoperated platform can give a very immersive experience. A FPV quadrotor platform was built to try the FPV experience and the results was satisfying. Visual Feedback is done using a video telemetry on 5.8GHz band. APM 2.7 ruuning Arducopter was used…
