As I am not a big fan of TV, I may be wrong if I say that this is probably the first time that a French public TV channel spends a couple of minutes about FABLABs during the news. However, this is the first time that the information appears in my press review. The presentation […]

Sometimes ago I decided that I was fed up taking risks at soldering tiny chips and components using my good old JVC soldering iron. By the way, I strongly recommend this beast of burden which is still working absolutely fine after more than 20 years of use. This is a perfect companion for field service because of […]
I am missing my words to express how awesome is this presentation Many Arduinoos visitors are aware about quadcopters, but we were probably missing the capacity of executing cooperative works of these drones.
Part 1, 2, 3 RIGOL 1052E DSO review In the 80s, I have been using the top most fancy oscilloscopes from HP. Unfortunaltely, they were heavy, mine was an analog one, without memory, and they were expensive for private use. In the 90s and Y2Ks, I have been using a basic ITT analog scope: forget it. And then […]
Part 1, 2, 3, 4, 5, 6, 7, 8, 9 RIP my first Adafruit Industries ADXL335 based accelerometer! I used it so much and in so many agressive situations that I managed to break it down! Now, why bother designing a PCB, wasting my time and burning my fingers? I ordered a brand new accelerometer from Adardfruit, via Snootlab. The new version […]
Part 1, 2, 3, 4, 5 After some new experiments on sound analysis, I used a different design for the microphone amplifying section, that I am happy to share with you (From the statistics of Arduinoos, I know that sound capture is a topic of major interest for many of you). Here is the schematics that I shall explain […]
Part 1, 2, 3, 4, 5, 6 Here is an amazingly simple and effective application that applies the photovoltaic properties of LEDs. Two identical extremly simple Arduino platforms are used. Each of them is fitted with a LED and a pushbuton. In idle mode, the LED is biased in photo sensing mode, waiting for potential signal. Each time the push […]
