After some research, I decided to find a way to join Freemasonry. The most reliable method is to know a mason, so he can recommend you to his lodge. But if you do not know anyone of them, then you should come up with something else. The easiest option is to fill the form on the UGLE website: But after a few weeks of no response, I decided to give a try for another way. I went to the Freemasons’ Hall and asked a receptionist who I can talk to for more information about masonry and joining. He said… More

Arduino Basics #3: Control WebGL landscape with analog input

This time we should play around an analog input. For this experiment, I am going to use a potentiometer. Previously, I controlled LEDs remotely using a web UI, so why not to turn it over and control web content with analog input on the Arduino board. Another technology I am interested in exploring is WebGL, which is used to create 3D objects and environment on the web. We have this code to read data from Arduino and send it to our web app via PubNub: See the Pen Analog input… More

Only the paranoid survive

“Only the paranoid survive.” — Andy Grove Andy Grove was a Hungarian refugee who escaped communism, studied engineering, and ultimately led the personal computer revolution as the CEO of Intel. He died earlier this year in Silicon Valley after a long fight with Parkinson’s disease. Browsing the web I came across the story which is a bit disturbing: I’ll never bring my phone on an international flight again. Neither should you.

Arduino Basics #2: LEDs Remote Control

I started with the simple task to make LEDs blink, and then after basics, I had started wondering how to control them remotely. So here is what I have come up with. I am using here PubNub Data Stream Network and Johnny-Five, an open-source JavaScript robotics framework that lets you program an Arduino with Node.js. The LEDs are remotely controlled via a web portal. Remote controller code: See the Pen Remote control for Arduino #2 by Roman Trilo (@romantrilo) on CodePen. More

Getting closer

After I have done some reading about the Freemasonry on the Internet, I decided to go to the heart of the organisation — Freemasons’ Hall. It is the headquarters of the United Grand Lodge of England and the principal meeting place for Masonic Lodges in London. Grand Lodge has been in Great Queen Street since 1775, the present Hall being the third building on the site. First of all, I have got to the museum and the library. It was really exciting and informative. Photo archive:… More

Arduino Basics #1: Blinking LEDs

I am very excited about the possibilities of Arduino, so I am happy to play around with it. For the beginning we were supposed to figure out a small code to make LED blinking pattern, but I decided, that it is too simple and what if I want to create a pattern using few LEDs. So here is the result: And here is the code: //Flowing LED Lights void setup() { for(int thisPin = lowestPin; thisPin <= highestPin; thisPin++) { pinMode(thisPin, OUTPUT);} } /****************************************/ void loop() {… More

Is Freemasonry a religion?

For quite a long time I was interested in Freemasonry, but never had enough time and motivation to go deeper and explore this question in details. First of all, it is not really clear whether this is a religious institution or not. They position themselves as a non-religious, non-political, fraternal and charitable organisation. You can belong to whatever religion you like and join them. Actually, the first requirement to become one of them you should believe in God, but you can not discuss religion on the masonic meetings. There is a lot of controversy about this topic and the best… More

What is Freemasonry

As I decided to explore Freemasonry as a tribe, I should get more info about it. Of course, Wikipedia was a starting point: Then I have got to the website of the United Grand Lodge of England: The first thing you can find there is the question which bothers most of the people who hear about them not only for the first time: WHAT IS FREEMASONRY? Freemasonry means different things to each of those who join. For some, it’s about making new friends and acquaintances. For others it’s about being able to help deserving causes – making… More
