Hello, welcome to my webpage of my own contraptions. My name is Walter Lee and I am an Adult Fan of Lego (AFOL). I have a Four year Degree in Computer Science (with a minor in theoretical mathematics) and I've always been fascinated with electro-mechanical things. I work with both Lego Technic and Classic Lego. My Lego interest also includes Mindstorm RIS-NXT-EV3, 9 volt Lego trains, RC Legos, and Lego Educational Dacta systems. I like things that move and light up and so many of my own creations have moving parts, light up, and function is some way or another. To demonstration some of my Lego creation's functionality I have embedded videos for some of them, e.g. the Power Function T-Rex Dinosaur Robot or how to make a lego bracelets. I try make to make it a habit to test every one of my creations for functional performance.
I came from a very poor family but I was fortunate enough to receive two large Lego set (the big wheel set with blue pieces, and town site set with the "Esso garage" printed white block) as Christmas gifts in the 1960s when I was a very young child - I stopped playing with Lego around 1968 (?4th grade?). About 1997, I gave away my childhood Lego collection to my older sister's nephew when his father(my brother in law) bought him an Robotic Invention System (RIS) kit. I had just taught myself how to program and build 8 bit and 16 bit computers, and I was not impressed with the RIS at the time. Why? The RIS programming language for the SDK was weak and the number of ports were small and the servos and sensors choices were small.
It was about 2009 when I started buying Lego sets as gifts for my younger sister's nephew and niece that I decided to buy the Lego Mindstorm NXT 2.0 for myself just to study in my spare time. Why? The SDK appeared more refine and the number of ports were expanded and the sensors and servos choices were expanded. However, after playing with the NXT 2.0 I was disappointed. I found the instructions to the set rather limiting and realized that to do more I needed something extra --which led me to researching Lego Educational Dacta systems and Technic systems. Online videos of NXT and Technic MOCs suggested that I had not assessed building potential correctly.... At which point I purchased my older sister's nephew RIS kit (which he never took a deep interest to) and got my my original Lego collection back in the process! Soon afterwards I started posting my own creations here on this website.
I'm a member of the Washington DC Metro area Lego User Group, the Washington DC Metro Area Lego Train Club, and the Charm City Lego User Group. For 2014-2015, I am providing technical support to the First Lego League Probemasters (1175).
If you have questions about any of the MOCs on this site, leave a comment and I'll respond.
