Parallax Completes Open Hardware Vision With Open Source CPU
First time accepted submitter PotatoHead (12771) writes "This is a big win for Open Hardware Proponents! The Parallax Propeller Microcontroller VERILOG code was released today, and it's complete! Everything you need to run Open Code on an Open CPU design. This matters because you can now build a device that is open hardware, open code all the way down to the CPU level! Either use a product CPU, and have access to its source code to understand what and how it does things, or load that CPU onto a suitable FPGA and modify it or combine it with your design." -
Home-Built Turing Machine
stronghawk writes "The creator of the Nickel-O-Matic is back at it and has now built a Turing Machine from a Parallax Propeller chip-based controller, motors, a dry-erase marker and a non-infinite supply of shiny 35mm leader film. From his FAQ: 'While thinking about Turing machines I found that no one had ever actually built one, at least not one that looked like Turing's original concept (if someone does know of one, please let me know). There have been a few other physical Turing machines like the Logo of Doom, but none were immediately recognizable as Turing machines. As I am always looking for a new challenge, I set out to build what you see here.'" -
Companies Selling Microcontroller Kits?
An anonymous reader asks: "I'm in college working on an electrical engineering degree, and I've had a few labs so far involving microcontroller setups. I'd now like to start doing some microcontroller projects of my own devising, so I'll need a programmer, the development software, and the MCUs themselves. The problem is that I don't have a wide experience with the different companies selling this sort of equipment. I know about the BASIC Stamps and the PIC offerings, but what other architectures are there? Both of the MCUs I've named have development tools, but they're for Windows. Are there any companies out there that supply their tools for BSD/Linux? What open source projects are there working on this (I've found gputiles). As always, free (as in beer) is good for us college students. :-)"
