When conversation turns to the older Nokia mobile phones, it’s unlikely to be the long battery life or ability to conjure a signal out of thin air that tickles people’s memory, instead it’s the Snake game built into the stock firmware. Snake was an addictive yet extremely simple game in which a line of pixels — the snake in question — was navigated around the screen to eat the fruit without crashing into walls or itself. As the game progressed the snake grew in length, making it a surprisingly difficult challenge. If you hanker for Snake, as [VK5HSE ] writes, you can now play it in a PCB layout.
The software in question is PCB-RND, a cross-platform open-source PCB CAD tool, and the game is achieved through the magic of user scripting. Simply download the script, run it in your favourite circuit board, and away you go!
We can’t imagine a productive use for this piece of software, but it wouldn’t surprise us to see a snake slithering into a few boards we feature. It does provide a handy reminder though of the power in your PCB CAD tool’s scripting features, something it’s likely not many of us use to their full potential.
We’ve featured [VK5HSE]’s work with PCB-RND before, in a very useful Eagle import tool.
Since Autodesk’s acquisition, Eagle has been making waves in the community. The de facto standard for Open Hardware PCB design is now getting push-and-shove routing, a button that flips the board over to the back (genius!), integration with Fusion360, automated 3D renderings of components, and a bunch of other neat tools. However, Eagle is not without its warts, and there is a desire to port those innumerable Eagle board layouts and libraries to other PCB design packages. This tool does just that.
The tool is an extension of pcb-rnd, a FOSS tool for circuit board editing, and this update massively extends support for Eagle boards and libraries. As an example, [VK5HSE] loaded up an Eagle .brd file of a transceiver, selected a pin header, and exported that component to a KiCad library. It worked the first time. For another experiment, the ever popular TV-B-Gone .brd file was exported directly to pcb-rnd. This is a mostly complete solution for Eagle to KiCad, Eagle to Autotrax, and Eagle to gEDA PCB, with a few minimal caveats relating to copper pours and silkscreen — nothing that can’t be dealt with if you’re not mindlessly using the tool.
While it must be noted that most Open Hardware projects fit inside a 80 cm2 board area, and can therefore be opened and modified with the free-to-use version of Autodesk’s Eagle, this is a very capable tool to turn Eagle boards and libraries into designs that can be built with FOSS tools.
Thanks [Erich] for the tip.
