All of us use some of the Software as a Service (SaaS). In this article we are discussing which Software as a Service (SaaS) still important to the users as the cost of dedicated, VPS, cloud servers declined and declining to afford & number of F/OSS software increased. It is off-topic matter to mention, yet Platform as a Service (PaaS) apparently failed to convince from developers to the CIOs. … [Read more...]

Arduino LDR/Photoresistor and LED Based Light Meter
These projects are good for the beginners to learn basic things. We are showing a basic light meter, you'll try to add a push button to start and another push button to stop. In previous articles we have shown how to create basic sound meter with microphone and Arduino. That circuit was slightly difficult. LDR aka Photoresistors are more easy electronic component. Indeed, you can directly use a … [Read more...]

How to Install and Set Up LXD on Ubuntu 16.04
LXD works with a directory based storage backend. LXD is lxc with strong security. We can install LXD, ZFS and Bridge-Utils on Ubuntu 16.04 and configure that LXD to use a physical ZFS partition or loopback device combined with a bridged networking setup allowing for containers to pick up IP addresses via DHCP on the vLAN. For a dedicated server which runs multiple web sites with Linux containers, … [Read more...]
Arduino and LED Bar Display : Circuit Diagram, Code
LED bar display is actually like multiple LED, it is not like Arduino modules like TM 1637. Here is a guide explaining the basics, circuit diagram, code on Arduino and LED Bar Display. We need no extra library for the LED bar display but we need correct circuit and logically correct code to use this electronic component. Big advantage of LED Bar Display is it is quite cheap, we can use with IC … [Read more...]
List of Electronics Prototyping & Project Materials
After Twelfth grade, in standard countries degrees really matters least for the intelligent and hard working persons in the field of applied science. Several times it has been proved that traditional education mostly good for nothing and humans with no traditional education became the best possible on the niche - Thomas Edison and Steve Jobs are two good examples. And in this era of information … [Read more...]
Arduino UNO Prototype Shield Tutorial
Normally we use breadboard for prototyping and various types of prototyping boards to make an Arduino project permanent. In such case, usually we do not use the Arduino development board but we use the components to build Arduino. However, not all project needs so much effort. For some, making only the non-Arduino part of circuit permanent works fine. In this Arduino UNO prototype shield tutorial … [Read more...]
