I moved to another city at the end of June. Still in Massachusetts but much closer to work. I’ve mostly settled in but still have many boxes that need to be opened.
The last tutorial I made was posted on June 1st and I showed you How to control an LED from your browser!
In the meantime, enjoy my RPi tutorial from June 1st:
Since the holiday break, I’ve been working on this little Raspberry Pi project. It’s dubbed the Website Uptime Monitor.
I use several uptime monitors including pingdom and Jetpack (used on this site). And I typically use the Free version because I am okay with being offline for a few hours if it comes to it. But then I thought, I can create my own uptime monitor that works just as well as the paid versions and I’ll have full control!
Of course I don’t have the skills or time to do what these paid monitors do but thought I’d try anyway. I also wanted some kind of visual indicator if any of my sites go down. And in comes the Raspberry Pi. I love the Pi. If you know me in person, you know that I have a dozen different Raspberry Pis around the house doing different things, such as control my lights, act as PiHole, PiVPN, etc.
You can watch the quick demo of the software here:
If you prefer to read about it over watching a demo video, keep reading!
The idea I had was to have three lights, like a traffic light: red, yellow, and green. I’m still working on the rules for when the lights come in, but they’re as follows: – Only Red – either everything is down or my internet is down – Only Green – everything is good! – Yellow – this light can be on in conjunction with the green light. This will come on if 1-3 sites are down. And if Green is on along with yellow, it means at least some sites are loading.
Pretty simple rules but I still think I can do better. That’s why this is still in beta! Current version at the time of writing this post is 0.3.0-b01.
The application will check sites every 15 minutes (this is configurable) and record all activity in a database. If a site is reported down three times in a row, the app will send an email with an outage report. The Email notifications are also stored in the database so you can look up whether or not an email was successfully sent out. Failure to send an email would typically mean that your internet was down.
Since everything is stored in the database, everything is reportable! For this, I created a Flask app with a bunch of API endpoints that can be accessed by any web application. These endpoints will output data from the MySQL table into neat JSON. You can also write to the databases using POST and PUT API calls.
I’m back with another Raspberry Pi giveaway and a tutorial. I think this one is pretty decent, even though the entire video is over 22 minutes long. About 3 of those minutes are demos of the product and another 2 is talking about the giveaway. So really, only about 17 minutes of tutorial!
In this video, I show you how to create your own audio reactive LED strip using some WS2812b lights. Make your holidays a little more fun with some dancing lights.
It’s been a while since my last update. My last updated introduced my Easy jQuery series. That was more than 8 months ago. And in total, I’ve created 21 jQuery tutorials!
But now I’m moving forward with another adventure. I have decided to start doing a Raspberry Pi tutorial series! The first video will premier on Saturday November 10th at 6 pm EST. In this video you will learn how to set up a Headless Raspberry Pi. Along with learning something awesome, you’ll have a chance to win one of two Raspberry Pi Zero Ws!
The above is just the intro video, where I decided to start the index at 0. As of today, I have uploaded 4 tutorials (5 videos) and are getting a 5th one ready for next Saturday. Unlike my JS tutorials, I’m only posting one tutorial every 2 weeks because there aren’t as many topics to cover.
This marks the beginning of a new era for my Easy Programming project. For years, I have been making programming tutorials. I first started with C++ tutorials. I then stepped into basic Excel tutorials. I kept that on for a few years.
Say Hello World!
If you have any questions or would like to see a specific topic covered, please comment in the videos, I am more than happy to answer your questions and fill your requests!
I’ve had my Samsung Galaxy S4 for almost 3 years. It served me well. Up until two months ago, it was working beautifully. But it decided to go crazy and crash a bunch of times, and continued to do so multiple times a day. So I decided to get a new phone.
There we a few contenders including the Nexus and iPhone. I’ve always been an Android guy so I crossed off the iPhone. At the time, the Galaxy S7 was still weeks away from release. But then, a colleague of mine mentioned that that Samsung is handing out free Samsung VR headsets with all S7 preorders. And I further read that Samsung added a full year of Netflix if you ordered directly from T-Mobile. So I decided to wait and preorder.
My phone arrived on 3/12. I created a little unboxing and first look video below, check it out! If you want to know something about the phone that I can look into before you go ahead and purchase, let me know, I’m more than happy to oblige.
