Have you ever seen someone making a drawing on an oscilloscope screen? Did you ever wanted to? Well, now you can. And, by "now", I'm not saying that you need to buy some hardware or mount some hacking device to create your drawing. "Now" is right now.

Let me introduce you to Rabiscoscopio: A simple and free software that convert your drawings into oscilloscope images.



Fake Hollywood bomb

On the night of March, 22, we had the first official activity of our hackerspace, and a big one: SJC Lightning Talks, which brought more than 150 people to check 9 quick presentations.

When speakers have to shrink their usual 45-minute presentations to fit in time limits as small as 5 ou 10 minutes,they usually start to mess up with other speakers slots. To keep all presentations, plus registration and meals, inside our 3h limit, we had to find a way to force speakers to keep the defined time limits.

Home-made arcade machine

This is my home-made arcade machine:


I used to have this full-size retro arcade that I've also done, but that thing was a huge monster at my tiny apartment. This new guy is small, and has been a huge success when people come to my place. I usually just leave it connected to the TV, when I'm expecting to receive some guests.

The project is really simple:

Cat Fountain

Tired of attending your cat's requests to open the faucet? I was. And also my region is going through one of the biggest droughts in its history

However, those comercial cat fountains are very expensive here, and they keep the water flowing the whole day, even when no cat is around.

So I solved all my problems by building this Automatic Cat Fountain. It's really simple, the parts are cheap and easy to find, and it takes only a few hours to build. And it's open-source! :)
