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.

        It's remarkable that the world managed to function at all before the age of modern medicine.

        Just because humanity survived through it doesn't mean it is responsible or ethical to strip it away in circumstances when you don't understand the consequences.

        The truth is, people before modern medicine might stand a better chance of dealing with a given health issue because they knew folk remedies which may have helped (though they didn't always help, they were rarely harmful). Today, most of us have an almost total lack of ability to deal with major health issues without modern medicine. The same is true with cellular communication -- people were fine without it at the time, but they (we) have grown fairly dependent on it today. Take it away unexpectedly, and they're worse off than when it didn't exist.

      Anytime the Wavebubble comes up, somebody brings out the argument that it could potentially block a call to Emergency services, but really this isn't a very realistic scenario. The Wavebubble really has a pretty limited range, from the project page: Effective range is approximately 20' radius with well-tuned antennas" [ladyada.net]. That's a small enough area that to anybody within range it would just appear like a small dead spot in coverage and just like a regular deadspot, they'd probably walk around a little bit until they got service. It doesn't impede emergency access any more than standing on the wrong side of a building might. Furthermore, a 20 foot radius is small enough that if there is somebody nearby needing emergency services, you can almost certainly see them and help out yourself.

      If someone on a cell phone is annoying you, ask them to keep it down or turn it off.

      I work in a retail store and people are constantly coming up to the counter talking on their cellphones, oblivious to how rude it is to the people around them and how often it inconveniences other customers (customers talking on their phones generally will not be paying close attention to the transaction or myself, causing the sale to take longer). I can understand and agree with why cell-jammers are illegal, but still, everytime a particularly obnoxious customer comes up to the register on their cellphone, it's hard for me to avoid thinking about building a Wavebubble. What's stopped me thus far is that I really doubt it would do any good -- if I cut off their signal they're just going to try to redial whoever they were talking to, as distracted as ever.

      • 20' is enough to ensure everyone in a train carriage or cinema is unable to receive or make a call (the lower signal strenth in a cinema will make it more effective).

        They if they checked the signal before someone activated the jammer they wouldn't know they were unreachable and they could be someone who's on call (doctor, firefighter, coastguard etc.) or waiting on a message.

        • Fortunately, the solution is obvious.

          Hook up an S-meter to a cell phone vibrator and install them in a set of brass knuckles. If there is a jammer, just use the light buzzing to guide your fist to the proper location.

      • Sorry but "it probably won't be an issue" isn't a legitimate reason to use this device.

        People can be annoying. Cellphones are just one of the ways they do it. Get over it.

    • I reserve the right to jam cell phones in my property. If I had an establishment like a concert hall, auditorium, movie theater, etc., I would install cell phones jammers. Jammers should not carry any penalty.

      So can the T1 and T2, and the OpenRISC architecture. It's surprising how many good, open source, CPU designs there are. The cost of fabricating them is still very high, but if you're making a consumer electronics device then it may be cheaper to tweak one of these and get a few hundred thousand ASICs fabbed than pay to license a design from someone else.

      • Perhaps you can help me, if you would. I've been looking for either a real thoroughbred FPGA-based CPU implementation or a very fast, low power SOC for a pet combinatorial project of mine. It needs to be wicked fast for integer ops; no need for floating point. It only needs a few K of RAM, and very little I/O to the real world. Do you have any pointers to examples of FPGA CPU's or SOC's that fit the bill?

        Thanks!

        • Obviously it's difficult to tell with such a sparse description of your project but it sounds to me like you might be better off implementing it directly in a HDL.

          Otherwise, if it's a pet project you might not care too much about the very best performance. In that case the SOC utility that the big two vendors provide with their FPGA kit (NIOS II with Altera, PowerPC with Xlinx) would probably be the best route to your solution as you'll spend less time mucking around with compilers and just getting the dam

      Depends on the project. In the case of projects like OpenCores [opencores.org] 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.

    • Digital hardware, like processors and such, are usually designed in a hardware definition language, like VHDL or Verilog, so it's not very different from computer software. Instead of compiling to machine code or byte code, it's compiled (synthesized) into something that can be loaded in an FPGA, or processed further for ASIC production.

    • Not really. Design implies a high-level overview without the full details. Open design software would give you UML diagrams or some equivalent. When people talk about open source hardware, they mean you have enough information that, given the equivalent of a compiler, you can produce an exact copy. For ICs, this typically means the HDL source is available. For circuit boards, it means the schematics are available. You can take these, modify them, and produce modified versions.
