Simple Alarm with Shell Script
In this post, we are going to develop a simple alarm with shell scripts.
To get the time we use date command. To play a sound file we use aplay command-line player. It is also a recorder. Since we are developing an alarm it must control the time continuously so we need an infinite loop. Source codes are given in the following.
Source Codes:
By changing the controlled time and sample.wav you can adjust it as you want.

Transmission Line Analysis Using Matlab
Matlab has a Radio Frequency Toolbox(rf toolbox). Using this toolbox matlab allows us to do some simulation and calculations about transmission lines, active components, RLC components, black box elements etc. In this post we are going to analyze a microstripline using 'rfckt.microstrip' class in the matlab.
Let's calculate characteristic impedance of a microstrip line at 1Ghz, 2Ghz and 3Ghz with the given specifications below:
thickness = 5.000e-09
width = 4.000e-04
height = 3.000e-04
To do the given task we can write the following m file and execute it. The output of the matlab is given below the codes.
Matlab Command Window Output:
