Part one, in a journey to upgrade an old robot. This classic 80’s robot This robot was also known as: Tandy Robie, Radio Shack Robie, Robie the Robot, Talking Robie, RS 4061, Robocom 1000, Robie Parlant, and Robocom Robot (Super).
A friend who recently acquired a CO2 laser cutter for his school recently sent me a message. “What is the difference between a laser that will cut metals and one that won’t?”. I thought this is a good question, as the answer will help with understanding how to work with many materials.
Managing arduino projects can be a nightmare because its hard to keep track of your hardware setup in your code comments. To enable easy documentation of pin assignments, I created a couple of ASCII art arduino pin-outs.
These come complete with ports, PWM and coms all marked. Simply paste as a comment into your code and marvel at your new found organisation.
I needed some fan guards for my arcade machine and for a neat little entertainment centre hack. Playing around I made a fish-eye honey-comb screen that looked pretty good. The pattern has larger holes near the centre of the fan and smaller holes where it counts.
Practical Iterative K-ary Tree (aka n-ary, n-tree) Traversal in C#. A surprisingly useful tool for the average programmer.
Introduction: A lot of components in the C# environment are essentially a K-ary [kay-er-ee] tree. From tree-view nodes, to serialising a type via reflection, to directory listings to menu hierarchies, and so on. Often we need to iterate through these types of structures, or our own trees, and we just write some code to do […]
I have felt for a while that web searching is still an awkward thing from a Human Computer Interaction point of view. So I made a wish list of simple improvements that would literally turn my world upside-down.
Laser engraving text on acrylic / perspex does not create a lot of contrast. This leads to the subject of painting text on the acrylic. I have developed some useful methods of achieving this that I thought I would share.
Firstly, you will find none of the “lets make homework cool” type stuff here. The Internet has become a much more stimulating place for maths, visualisation and generative images. This is in part driven by the death of those “java applets” as wonderful HTML5 based interactive maths content takes glorious hold. Trying to keep pace with […]
So your here because you just couldn’t resit the title… or you used some very odd search terms in Google. In any case, welcome to the article that gave me the most pause to write about so far. Background. !t was the 1960s (this decade is developing a bit of a reputation) and doctors were treating […]
