Earth Hour - How to save energy and resources (rule of thumb: What "YOU" do counts) #EarthHour

  • Turning the thermostat up 1.5C in the summer & down 1.5C in the winter cuts 400KG of CO2 emissions each year. What you do counts.
  • If you must drive, then carpool! and turn off the car while you wait. What you do counts. 
  • Replace your light bulbs with CFLs. CFLs use 75% less energy and last up to 10 times longer. 
  • If 10 out of every 100 cellphones were unplugged once fully charged, the energy saved could power 60,000 homes per year. 
  • Ditch the car and use public transportation, walk, bike, or roller-blade to where you want to go. What you do counts. 
  • Use a fan instead of air conditioning and put on a sweater before you turn up the heat. What you do counts. 
  • RECYCLE! What you do counts. 
  • A TV set can run for 3 hours on the energy saved by recycling just one soda can. RECYCLE! 
  • Turning off unneeded lights in a building can reduce the energy used for lighting by up to 45% 
  • The amount of energy saved from recycling 1 plastic bottle can power a 60-Watt light bulb for 6 hours! What you do counts.
  • Turning off the tap while you brush your teeth can save 10,902 liters of water each year. What you do counts! 
  • Imagine the additional savings if you turn off the tap while you soap, shave, or wash dishes! What you do counts.

Tahrir @ Cairo, Egypt #Jan25 ...The humor side ;-)

Image
             The Egyptian humor will never seize to amaze me, even in the darkest times we are still sarcastic, artistic and full of humor. A lot of people would expect that I'd state here some of the stories that happened, some of the horrifying videos, but I won't, so if you are here to know more about what happened, I am telling you from the start this is not the right place :)!               I will state here some of the comments, jokes, signs that are told at this time, right when we're still in the middle of the actions...while history is being made... Here we go... أفلام جيل الثورة: أبي فوق الدبابة, عودة النت, المندس والأجندة, الرصاصة المطاطية لاتزال  فى جيبي, في بيتنا بلطجية, كيف تصرف العفريت، رد نتي، ستاتس هزت عرش مصر،  حرامية في لندن، جاءنا الرئيس التالي، نحن لا نرمي المولوتوف ،الريس عمر سليمان يعنى ايه كوكولا زيرو.....يعنى تبقى واقف فى لجنة شعبية بتحشش..و ي...

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...

Arduino controlled two servos based robot - achieving a straight line

Image
Introduction In this article I will discuss how I came close to syncing the rotation speed of two continuous rotation servo motors to allow movement in straight line and control the speed of the robot forwards and backwards. The Problem If you are making a robot and want it to move in a straight line, and assuming you are using two motors for the drive, you need them to rotate in the same speed. As most people know choosing the correct motor type for the job is important, but sometimes you don't have options and need to work with what you have. Motor Types: Motor Types Source:  https://backyardbrains.com/experiments/MuscleSpikerShield_GripperHand Hobbyists & makers usually choose one of these motor types to drive their robot. To achieve a straight line, stepper motors seems to be the right choice since they can be controlled in terms of speed and direction accurately without encoders or feedback circuit. In my case I was stuck with servo motors, and thought ...
