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 […]

What’s inside an integrated circuit? We broke one open and scanned it for you at 12,800DPI

Because you always wondered what was inside. See if you can guess which IC it was? Useful image for teachers, overhead slides etc. NB: This is not always a good DIY or classroom activity. Be aware that some electrical components create a seriously hazardous dust when broken open. Rectifiers, Hi Power transistors, Older IC’s & IC’s with certain […]

Quick Graphs to make PCB Track Width and Silkscreen Ratios easy.

Recently I had to make a series of circuit boards using Eagle Cad.

I spent a lot of time calculating track widths to make sure my circuit board could handle the current I was using.
Then I had to do more calculations for font ratios. so that that all lines were wide enough to work with the silk screening process.

Sick of this; I quickly used matlab to create a few charts so I could look up the answers quickly.
I thought I would share these charts and the matlab scripts, hope they are useful.
