Light following robot

Hi.

Long ago during holidays I've made a light following robot. Very often people build these robots without using any microcontrollers or specified integrated circuits. And that's why I went for a little twist and I actually decided to build one with atmega88. It allowed me to not only ensure the basic functionality of the robot, but also I was able to add a new one - barrier detection. Which is pretty useful, when for example robot's path is obscured by some kind of object (thanks to the IR sensors robot will detect the obstacle and stop). Anyways the construction is so simple because I used undercarriage from my car. You can watch how robot works below:

Oscilloscope with new feature

Hello.

It'll be a short note. I've recently had some free time and so I was able to add a new feature to my oscilloscope. And it is quite useful one - synchronization with measured signal. You can choose the activation method as well (falling / rising edge). I've also tweaked the display management a bit. It now utilizes frame-buffering, which improves FPS significantly. Here is a video with the new version of the oscilloscope:
