How to Get Your HS420361K-32 4 Digit 7 Segment Display Working with an Arduino


Typically when I get new electronics components to play with, I just google the part number and lookup tutorials on how to get it working. This has been a pretty successful strategy more often than not. However, this wasn't the case when I needed to get the HS420361K-32 4 digit 7 segment display to work.

So You Bought Yourself a Raspberry Pi 3, Now What!


My second post when I started this blog was about my choice of a prototyping board to explore, and I started out with an Arduino. Back then, one of my arguments for choosing the Arduino over the Raspberry Pi was cost. While the cost factor hasn't changed all that much, I managed to get myself gifted a Raspberry Pi 3 (and that's how you bypass the cost factor lol).

So for the past couple of years I have been mildly exploring the Raspberry Pi 3 (emphasis on mildly), and what I'd like to go through is: "WHAT THE HELL DO YOU DO ONCE YOU GET A RASPBERRY PI?"

Coming up with Engineering Solutions that Matter


I had a conversation with my brother a while back where I was trying to pick his brain on how someone could figure out a problem(s) to solve using engineering techniques. My brother was a pretty solid candidate to pick since he's an engineer, (yes this is a family of engineering kids, parents sought their fortunes elsewhere).

Designing a Smart House

So I have been tasked with coming up with a smart house idea that is to be used to demonstrate the awesomeness of the Arduino to high school students.

The basic premise is that the house is supposed to be automated. It's supposed to have lights that turn on automatically when one walks into a room, lights that dim when the TV is on, an automated door that opens when it senses that someone is approaching, some kind of alarm system. So I have to figure out the logistics of how all these things work and how they can be managed by an Arduino.

Rooting the Samsung Galaxy S4 Mini (And Try not to Brick it while you're at it)


So recently, I decided that I wanted to root a Samsung Galaxy S4 Mini, because what is Android without root access, right?

My first attempt at rooting the S4 mini ended with me bricking the phone! Not a very good experience I tell you. Luckily, I was able to get it back up and running. But that is a story for another day.

For my second attempt at rooting the S4 mini, I decided to take as much precaution as possible and actually take my time.
