Progress On the Open Laptop

← Back to Stories (view on slashdot.org)

Posted by Soulskill on Saturday July 6, 2013 @05:50AM from the does-it-run-crysis-yet? dept.

An anonymous reader writes "Last October, we discussed Andrew 'bunnie' Huang's effort to build a complete open hardware laptop, called the Novena. bunnie has now posted a progress report on the laptop's design and construction, showing the latest revision of the board, the display, and a hack to use it as a secure router. bunnie says, 'At the end of the day, we're having fun building the laptop we always wanted — it's now somewhere between a python-scriptable oscilloscope, logic analyzer, and a laptop. I think it will be an indispensable tool for hacking, particularly for doing signal analysis which requires coordination across multiple protocol layers, complex trigger conditions and/or feedback stimulus loops. As for the inevitable question about if these will be sold, and for how muchonce we're done building the system (and, "done" is a moving target — really, the whole idea is this is continuously under development and improving) I'll make it available to qualified buyers. Because it's open-source and a bit quirky, I'm shy on the idea of just selling it to anyone who comes along wanting a laptop. I'm worried about buyers who don't understand that "open" also means a bit of DIY hacking to get things working, and that things are continuously under development."

  Except that this is exactly what he didn't do. Your analogy would be fine if he said something like "Reddit uses Javascript. Slashdot uses comment trees." Both statements correct, but none of them indicating any similarities or differences between the two. But when you describe Reddit as a "pure message board" and Slashdot as a "news aggregator", I think it's safe to say that one of the things that come to most people's mind that it indicates a difference in the sense that Reddit is probably going to have a significantly higher proportion of user-generated (primary) contents (not just links with summaries).

  If you've written the FPGA logic in a standard language like Verilog, then there's not much keeping you from moving the code between different FPGA chips, or even chips from different vendors.
  Of course, the idea of using FPGAs in a laptop seems rather silly to me; the whole point of having a laptop is to have something small which can be powered by a battery for a reasonable length of time. Using FPGAs instead of real ASICs and CPUs would drastically lower your run time. You might as well give up on the laptop idea if you're going to do that, and just make your own FPGA-based mini/microATX/miniITX motherboard and use standard desktop parts instead. Then you can plug in any monitor you want, and most of the other parts are commodity as well.

  There is the Open RISC platform, which is under GPL. It's essentially the HDL code of a MIPS variant that can be used on FPGAs. So if one built a computer - probably not a laptop - using that, then the hardware would be open as well if all the chips on the PCB were programmable i.e. either FPGA or Flash.
  Although I do wonder whether anybody, no matter how good at Verilog or VHDL, would try to reprogram the FPGAs on the card and redefine the interfaces b/w the parts? That would be the underlying point to having it open in the first place. Otherwise, once such a design is frozen, spin out ASICs based on that code, and optimize the power consumption vs performance.
  The point about free hardware being less important - once un-programmable parts are used in a platform, there goes the idea of doing anything w/ the GNU's Freedom 3 - the right to improve the program, and release your improvements to the public, 'so that the whole community benefits'. At that point, there is little difference b/w that, and a closed source hardware platform made up of unalterable parts. Yeah, most vendors may publish their specs, but that's not the same as giving a piece of hardware that can be altered any way one likes.

  The primary difference being, people have different expectations when it comes to something they laid done a decent some of money for. If you download a project that doesn't work and don't know how to diagnose it, you move on. Drop a $1000+ on some hardware and don't possess the skills to work it out , you may feel quite differently. No amount of initial expectation setting can change that when it involves someones hard earned money. We've seen that with Kickstarter, you are told upfront that you are investing in a product that isn't in production yet and people get upset when things don't pan out as planned.
