My brother-in-law has a safe that he cannot open. I may not be a locksmith, or have burglar skills, but I'm good at engineering so I'm going to build Levy a robotic auto dialer to crack the combination to the safe.

If you're like me you have creative ideas and sometimes they get trapped inside your mind. Here on Byte Sized Engineering I make project videos that get you excited about unleashing your inner maker and making those creative ideas a reality!
You shouldn’t need an engineering degree to make your ideas a reality. I suffered through years of engineering school so you don’t have to. I know how it feels to want to make something I’m excited and passionate about, but also feel overwhelmed by not knowing where to start. I’ve unlocked the secret to getting past this feeling of being stuck. In my videos I show you how to take complex problems and break them down into smaller, more manageable “byte sized” pieces.
If you want my recommendation on what you should watch, I put together this playlist for you. youtube.com/playlist?list=PL8Udln1nmXVBEdorJ2xU5VnXn1nfmMM--
