Cairo commuting

Commuting in Cairo!  image source  blog.eces.org.eg If you are reading this you are probably one of the ones suffering from commuting in Cairo, Egypt. That means you live on one side and working on the other. Living around Nasr City, Masr elGedida or 5th Settlement and working on the other side of town, Smart Village or 6th October city. Or of course the other way around. Oh I hear you, my heart is with you, there's a fair chance you've been through the following: You get up really early in the morning to avoid traffic, waking up a few minutes later or use your alarm snooze button, and you're toast! You know that if you're not on 6th October bridge by 7:30, or if you're just a tiny bit late, even by 5~10 minutes, that means you'll probably get stuck on October bridge and/or Lebanon square (ميدان لبنان) You arrive at work tired, because you woke up really early and went to sleep late the day before, or you were a little late this morning and you ...

Relay circuit module

Image
Circuits are somewhat like programming, sometimes you use ready made functions when you program. It is useful to have some basic circuit modules around you in case you need to test something or want to work on your next robot and don't need to create everything from scratch. In this article or tutorial,  I'll share with you making a 12V relay circuit module. A relay circuit is used to control (switch on/off) AC or DC voltage line without affecting your micro-controller (Arduino, Raspberry Pi, PIC, AVR...etc.) or digital control unit, at least when done right :)! When you toggle the voltage on a relay coil, it works as a mechanical switch, moving a metal arm/contact from one node to the other, literally switching on or off. Read more about relays here I started drawing the circuit using Eagle PCB design software , there is a free version for personal use here Eagle Express . Schematic: PCB: Once you have the PCB design ready, you want to print and transf...

The mind...what an interesting creation!

Image
Ever thought what if you had a different mind? a different life? or maybe different parents?! etc... These questions -if one could wonder- would simply result in one thing, that you...would not be you! Having a different mind means that you won't be thinking the way you are thinking now, a different life, means different experiences thus a different mindset. Having different parents means different sets of chromosomes... which all leads to a totally different person other than you! That being said it means that you will literally be someone else! and there's a good chance you wouldn't be thinking about these question in the first place! A mind is an interesting creation indeed, imagine all the things you do, all the things you know, all the things you calculate on daily basis (yes, even if you think you're not good at math) and I'll prove it for you with more than a few examples: Driving - requires constant distance calculation and 3D visualization, h...
