This is a very simple weekend project: A gas leakage alarm for your kitchen.

It's based on a MQ-2 sensor, which detects LGP (Liquefied Petroleum Gas), alcohol, smoke, propane and some other gases. It comes froma family of sensors, all of them with the same pinout, so any project using them can be easily "ported" to detect different gases. For example, MQ-7 detects Carbon Monoxide and ME2-O2 detects Oxigen.

This is the result of my home-made motion capture system. I've used it to animate videogame characters for another project

Of course, there's a lot of free game assets around the net, but, as usually, it's funnier to go with your own solution.

On the video, the character seems to lose a keyframe, but I've managed to fix this at the game

 

This month I was invited to help at a local videogame faire, Arena Game Show. The guys from Python Brazil, the Brazilian Python community, got a stand at the event and were planning some workshops and classes.

This is the game I brought there:

 

I was getting too much distortion on my drawings on the oscilloscope. After checking that the waveform was correct, I started trying different sound-cards, and figured out they can make a huge difference on the final image.

 

Here is what I found about them. I tried the following sound-cards:

I've been working on a full-body homebuilt 3d scanner.

Here you can play with a virtual version of me:

This is a low-poly 3D model. These files are usually too big for web, so I reduced it to around 4k vertices. The original was 100 times bigger.

My homebuilt 3d scanner is comprised by 3 Kinect sensors and two lighting poles. I used a led strip for the poles. They are used to set an even lighting around the 3d object.

Cassapa is a system to help aiming at pool games. It uses augmented reality to help the player to adjust the cue direction. Check this video:

How it works

Everything starts with a webcam, fixed at the ceiling above the pool table.

Thanks for visiting! This is the virtual space for my software/hardware projects.
