In the last post I talked about putting an LED instead of a light bulb on my bicycle rear light. I wasn’t satisfied with the luminosity, I was expecting something somewhat brighter, but I actually think the original incandescent bulb was much brighter. Therefore, I bought a 1W LED, and after some researching, it seems […]Read more "Changed the flux LED to a 1W LED"
So a few days ago my rear light burned up. It’s not that it’s very important, what’s essential is the front light during a night. Since there’s that reflective red plastic on the back, I wouldn’t worry. Anyway, I decided to replace the burned bulb. But I felt bad about placing in its place another […]Read more "Putting a LED instead of an incandescent bulb on my bike"
I decided this weekend to work on a mini-project, since it came to my mind during the last week. I found that my Arduino starter kit actually had an LM35 temperature sensor, it’s just that I noticed that quite late. The LM35 is a sensor that varies its ouput voltage proportionally to the temperature and […]Read more "Visualizing temperature as color using an RGB led, a LM35 sensor and Arduino"
This is a small project I was done with in about one hour(I didn’t found a use for it, but I’ll update the post if I do :D). It’s easy to build, especially for beginners like me. And the result is satisfying. I used 2 blue leds, and I tested the circuit on my pc […]Read more "Making a LED flasher"
One and a half year ago my audio system(Manta Merlin 2.1, aprox 25W RMS) made a loud bang. It scared the crap out of me. I was, in a way, suspecting something like that would happen because the back panel was seriously hot all the time. From that moment, the bass didn’t work anymore. In […]Read more "Repairing the Audio System"
