PCMCIA Computer Project Aims Even Higher (and Cheaper) Than Raspberry Pi

lkcl writes "An initiative by a Community Interest Company Rhombus Tech aims to provide Software (Libre) Developers with a PCMCIA-sized modular computer that could end up in mass-volume products. The reference design mass-volume pricing guide from the SoC manufacturer, for a device with similar capability to the Raspberry Pi, is around $15: 40% less than the $25 Raspberry Pi but for a device with an ARM Cortex A8 CPU 3x times faster than the 700mhz ARM11 used in the Raspberry Pi. GPL Kernel source code is available. A page for community ideas for motherboard designs has also been created. The overall goal is to bring more mass-volume products to market which Software (Libre) Developers have actually been involved in, reversing the trend of endemic GPL violations surrounding ARM-based mass-produced hardware. The Preorder pledge registration is now open (account creation required)." Of course, the Raspberry Pi is not only only much further along, but has recently announced an expansion module (the Gertboard).

      so, early alpha boards go out to people prepared to take a risk, but who have the money spare (under $100, gosh, wow, break the bank why not) to consider "what the heck, this is cool, let's support this initiative" but at the same time have some expertise in embedded GNU/Linux development, and they might actually get something that works perfectly first time, and they're the ones that got it, before anyone else.

      beta boards go out to people who want something that, hardware-wise, is pretty much guaranteed to work 100%, but maybe the software's not all there, and they might have to (gosh) get involved and help write it.

      stable boards go out to people who really would "just like something that works, thank you, where's the debian distro image, where's the instructions for putting everything onto an sdcard, heck, where can i buy a pre-loaded MicroSD card so i don't have to do that, even".

      lkcl, before you jump into production please make sure that you don't want your SATA and USB work. Because they aren't very likely to; the PCMCIA connector is not a controlled impedance part, and your pinout requires 90 Ohm differential for USB and 100 Ohm differential for SATA. Ethernet is also 100 Ohm, but it has plenty of margin. Even if the board works on the bench, it's not the right thing to do. You need a proper differential connector, something that you can get from Samtec, for example.

      I really don't know how much you are an expert in manufacturing, but I built a number of professional designs, and I strongly suggest that you don't pick an old, obsolete connector just because you think it is cool. You need to consider the other side of the connector. How many PCMCIA cages can you find at Digikey? How many of them are easy to solder by hand? Hell, this connector would give *me* trouble, and I can solder 0402 all day long under the microscope. This connector has pin spacing of 0.635 mm, and practically none of your customers can solder it.

      I still don't quite understand the business idea of your product. By "business" I don't mean making money; I mean "delivering value," making good things. What value do you expect to deliver if nobody can connect to your board? Your super-small form factor is a problem here. Very few electronic enthusiasts are so much concerned about size and space. They are far more concerned about being able to see the parts without using an electron microscope. If you'd ask me, I'd say you need to think how your customers are going to use your product.

      The talk about standard connectors ... if you want it done right, use COM Express. These modules are interchangeable and your product would actually fit into an existing market. You can actually sell the thing without Slashdot. Inventing your own standard, using an obsolete connector and breaking the electrical signaling requirements will not do you any good. You are not large enough to establish a competing standard, and your design is not as good anyway. But if you don't want to deal with COM Express (which is not a pleasure to solder either, I admit) then just forget the unification and use plain vanilla 0.1" headers for everything except high speed interfaces.

    I'm not a programmer or a hardware hacker. I don't know anything about soldering circuit boards. I'm just a guy who likes to surf the net, write stories, play games, hang out on-line, and so on. What is the availability of this $15 device going to mean for me?

    I mean, at least (as far as) I know the Raspberry Pi is going to be producing fully-realized devices that I can buy, plug in a keyboard and monitor and Ethernet cable, and I'm done. It sounds like this project is just about building a circuit board. And while it's nice it will be 40% cheaper and three times as fast, I'd like to know what I could do with it if someone came up to me on the street and handed me one.

    if they _literally_ handed you one on the street, you'd be able to plug in a USB-OTG-powered hub, then you could put in a keyboard and a USB ethernet, and also an HDMI monitor, and some headphones.

    if they also included the "micro-header" that is also a planned product, you'd also be able to plug in an ethernet cable (without the USB internet dongle), and you'd not have to plug in that USB-OTG hub, you'd be able to put a standard hub on instead, and also power it from a 5V PSU, and you'd also be able to connect a standard (externally-powered) eSATA drive.

    oh, and there's a MicroSD slot, so if the man-on-the-street had taken out its OS card before giving it to you, you'd be able to download ready-built standard GNU/Linux OS distros, shove them in and go.

    so hell no, it's most definitely *not* about just "building a circuit board" - that's just the first step.
