Open Source Hardware, For Fun and For Profit
ptorrone writes "Lots of open source hardware articles making the rounds this week, first up — Wired has an excellent piece on the Arduino project, an open source electronics prototyping platform, its founders and business model (they have sold over 50,000 units). And next up MIT's Tech Review has a profile on a few open source hardware businesses including NYC based Adafruit Industries best known for projects like the open source synth (x0x0b0x) and 'fun' projects like the Wave Bubble, the open source cell phone/wifi/GPS/RF jammer."
Radio Jammers are most definately not fun. It's bad enough the ones that send out a burst designed to disconnect phonecalls but one that's designed to run for 2-4 hours...
If someone on a cell phone is annoying you, ask them to keep it down or turn it off. Don't potentially block a call that may be to (or from) the emergency services or another life or death communication. There's a reason jammers carry stiff penalties in most Western countries.
Depends on the project. In the case of projects like OpenCores the term "open source hardware" is very apt because the project consists of Verilog and VHDL files which are essentially programming languages (similar in many ways to C and Pascal) which are compiled as hardware designs for chips instead of programs. For other projects, it's a little more abstract, but still fitting, I think. I mean, open source software is software that provides with all the files you need to build a program yourself and allows you to modify them to suit your needs. An open source hardware project would generally provide the same thing, but instead of source code, it's schematics and board layouts.
