For nearly 2 years, I have been experiencing unstable internet connection via Wi-Fi. I always thought it was the Internet Service Provider, Mauritius Telecom’s fault but it tends out that the problem was with my router. These are a few ways to improve the transmission range of your router by only adjusting the configuration. Wi-Fi […]
After a long semester with nearly no time to tinker with the Raspberry Pi, I am back, this time experimenting with the Passive Infra-Red (PIR) Sensor to build a motion detector alarm. First let me explain briefly the working principle of the PIR sensor. All objects with a temperature above absolute zero (0° K or -273° C) […]
Electronics are very fun to play with but adding computer science to it makes it more fun. Following the previous post of using a breadboard, we are now going to control program LEDs to flow by a certain pattern using the C programming language on the Raspberry Pi. The Raspberry Pi consists of General Purpose Input/Output […]
As mentioned in my earlier post, I bought a Raspberry Pi 3. I also bought an electronic starter kit to use with it. The kit came with a breadboard, a board used for prototyping circuits. You might find it funny but I did not know how to use a breadboard. Breadboards come in different sizes and they […]
After having installed Raspbian on your Raspberry Pi, we will now boot the Raspberry Pi without any screen or keyboard. If you have not yet installed Raspbian, follow this guide. Connect your Raspberry Pi by ethernet (RJ45 cable) to the same router your PC is connected to. After having connected it, power it on. Find […]
I recently bought a Raspberry Pi 3 manufactured by Element14. The first thing to do in order to use it is to install an Operating System. There are lots of OS available for the Raspberry Pi such as Raspbian, Windows 10 IoT Core and RISC OS but for first time setup we are going to […]
This time, we got our hands on GateKeeper 2.0, a security hardware device that locks your computer when you walk away from it. The GateKeeper is manufactured by Untethered Labs, a start-up in the United States which sent us their product for review. The GateKeeper was crowdfunded on Kickstarter in 2014 and Untethered Labs took […]
Most desktop computers do not have the ability to connect to a WiFi network but there is a very simple and convenient way of achieving that without having to buy any additional hardware if you own an Android phone or tablet with version 2.2 or higher. Connect your mobile phone to your PC via USB. […]
Google, one of the biggest IT corporations was offline for about 25 minutes on 21st January in Mauritius since 6:25 p.m. The search engine was not working on these domains as far as we tested – .mu, .fr, .com, .co.uk . However, Google was accessible in other countries at that time. The DNS server also was […]
Fans are very important in computers; they are used to cool the CPU, GPU and sometimes the hard drive also. I used to think they cool the devices by blowing the heat away, in reality, they move air at fast speed toward the devices. The propeller ranges in sizes, the greater the size, the more […]
