WPA-PSK on Linux Intel centrino ipw2100
I recently converted my wired LAN to a wireless WLAN. This is the steps I made to create a WPA-PSK secured WLAN with my Intel centrino ipw2100 wireless card under Linux.I report here the commands and configuration files used . I hope those will be helpful for someone else. Note: this page contains informations updated on …
Variable resistance components: Thermistors and Light dependent resistors (LDR) on a Arduino simple circuit
In the past blog post we used a potentiometer to provide a user variable voltage to one of the Analog In pin. We then used the value read from the Analog In pin to set the blinking delay of an LED. This resulted in the LED which was blinking faster and slower depending on how the potentiometer …
Problems with Samsung u700? Let’s fix its flex flat cable!
I own a Samsung U700. In my opinion, a part from some little problems (metallic silver edge painting flaking off and the touchscreen buttons sometimes irresponsible or too sensible), I never had something big to complain about in my 9 months with it. The great stuff from this phone is definitely a great call quality, something which not all …

Preview of FreeIMU v0.3
Ok, I’m back hacking after a couple of months of hard work on the thesis which has been completed and submitted to the committee. 7 or 8 April degree! I still have to realize all of this.. Well, after a couple of days of relax I’m back to my regular hacking and I’ve been able …
Overclocking I2C to 800KHz with FreeIMU v0.3
I’m having some fun with my new Rigol DS1052E oscilloscope and the brand new FreeIMU v0.3 and it’s integrated logic level converter. I’m using the scope to stress test the I2C logic level converter and I found out that with Arduino and the Wire library hacking the code to overclock I2C to non-standard frequencies is actually extremely …

A libre breakout board for the MS5611-01BA high resolution altimeter sensor
As a first step in the development of FreeIMU v0.4, I’m starting my first steps with the MS5611-01BA high resolution altimeter sensor. According to its datasheet, this chip looks extremely accurate as it’s capable of a 10 cm resolution in altitude estimation. I already sorted out most of its electrical connections when I drafted the first designs of …

Functions with variable lenght arguments in Arduino
I was reading about variable length arguments for functions in the C programming language and I thought, “hey, will this thing work on an Arduino?”.. well, it turns out that yes, it’s working great! But, what are functions with a variable length? Well, the standard C printf function is a good example (not available on Arduino of …

First soldering experiment with the MS5611-01BA: huge fail!
This is the result of the first experiment trying to solder the MS5611-01BA on my LibreBB-MS5611-01BA. Looks harder than what I was expecting.. I was trying soldering it with hot air during the cooling down of the solder after reflow, obviously trying not to expose the chip to the hot air flow.. obviously a different path …
