If you are reading this, don’t worry, you are not the only who didn’t had the time to buy presents for Christmas, but its never to late! Therefore I will give you 5 ideas to buy the perfect geek gifts and make your nerd friends or kids happy !!
Note: Following products are part from my Amazon geek gifts wish-list and maybe my friends will read it too 😉 !!
Anyone said Minecraft? Yes, this is an amazing product, I would definitely buy this for my kid! He plays Minecraft anyway, so why not learn something good by making what he loves? The Piper Computer Kit comes with everything you need to assemble your own computer. Inside, you will also find our revolutionary learning system that teaches kids engineering and programming through a combination of engaging storyline, physical building, and Minecraft. This is an awesome item for a geek gift.

What is the purpose of an IoT project if you cannot access it live from everywhere using your smartphone? Even the name of the concept itself – “Internet of things” – suggests the idea of having remote access to your “things” from any place at anytime. In this ESP8266 Arduino tutorial you will find a 3 steps simple method to send push notifications messages from your IoT project to your smartphone using a standalone cheap a Wi-Fi module.
Examples of IoT applications that requires push notifications:

What people don’t know is the real benefits of making two ESP8266 talk each other. While many of you are trying to find how to connect two ESP8266 modules, you actually don’t have a good image about what applications or projects you can do by making multiple ESP8266 modules communicate between them. In this article you will find everything you need to know about benefits of creating an independent self-sustained Wi-Fi ESP8266 network.

Monitoring temperature or humidity via IoT (internet of things) is one of the most common home DIY projects implemented because of the large interest and benefits. Either you are monitoring temperature in your child room or you have an indoor self controlled heating system, this implies using one of the many temperature sensor available on the market compatible with Arduino or other development environments. Knowing the temperature with high accuracy can be crucial in many situations and for that you need to be well informed about sensors technical specifications. A temperature sensor can be find in the low price range between 0.5-10$ on most of the Asiatic known commerce platforms as well as in your local electronics shops.
In this article I will do a quick review on both DHT22 Temperature and Humidity and DS18B20 Temperature sensor 1-Wire, and I will compare them to give you an idea on which one fits better in your projects. I also invite you to see my quick video review and hands-on to make a better idea about how the sensors look and feel.
First of all, I own 3 of this sensors and I already implemented them in my projects, so I will give you real feedback about how they behave after being in production.

Technology goes ahead exponentially with each year whether we do something or not. With the same speed engineers work hard to reduce the size of every electronic device or component and loose most of the wiring. If you look back 20 years ago a device was called portable if you could rise it in your arms and carry up. Today nothing is portable if it can’t fit in your pocket.
Nowadays devices, either they are made for regular or industrial use, are based on wireless communication technology and the main reason is not to get rid of wires, but to be able to interconnect between them. Meanwhile buying a wireless device became natural for everyone and price for WiFi Ready equipment lowered with time passing.
While you read this, a WiFi microchip has no more than 5mm length and can be powered with as low as 10 micro Amps during sleep period. In this article we are going to test one of the cheapest and easy to use WiFi development platform, the ESP8266 arduino compatible device.

Can we monitor natural gas leakage with Arduino, without spending allot of money? There are many sensors available everywhere over the internet and most of them can be found very affordable in Asia largest online marketplace. They are quite cheap if you choose to buy them directly from manufacturers and not from the closest re-sellers. For instance, I bought the MQ4 just for 1.29$ from a well known China electronics marketplace.
