        Miscellanea :

        The Cardano was going to go out before Xmas, but then didn't. Then we were going to start taking pre-orders sometime in January... but then didn't. This has progressed past the stage where a simple handwave is satisfactory, so let's review together a field report from the CTO.

        Dear MP,


        ~ Cardano Tidbits (field report) ~

        This was originally longer, but I snipped a bunch of crap. If you like circuit diagrams, you'll have them in the end regardless.

        1) Mainboard power supply.
        Mainboard design was complete long ago - with the exception of one bit, which isn't trivial for the following reasons:

        Cardano powers on via two paths: A) Trigger is pressed ; B) USB power applied (drive mount), and powers off via two respective paths: A) Trigger is released, operation complete ; B) USB power is removed (drive ejected, connector pulled).

        In scenario (B), the microcontroller, SD, and block cipher ROM (distinct item from RSA ROM) operate on 5V from USB. In scenario (A), the entire device operates from battery. Note that perverse cases are possible - USB 5V is applied during (A), or removed during an incomplete (B). Thus it is necessary for the device to transition from one power source to the next, while also ensuring that certain components (RNG, RSA ROM) are powered exclusively from battery.

        Mode (A) requires a 'soft power' toggler. The entire rest of the planet solves this problem by keeping a microcontroller in perpetual 'on with low power' mode. We cannot do this - Cardano must be honestly OFF when not in use - not only to preserve battery power and obliterate SRAM 'remanent' keys, but to establish 100% known initial state for all operations.

        Finally settled on STM6600 to solve above. Handles switch 'debounce' (consult literature) and toggle, at the cost of ~$2/unit. Currently putting the finishing touches on the entire mainboard. Will source components (likely same vendor as previously) as soon as the design goes out to GP.

        2) Firmware.
        2a) Crypto basics (RSA, AES, GPG format minutiae) complete. All being in ANSI C, this runs perfectly happily in a Linux-based 'test harness' (just a command-line blob that walks through basic operations.)

        2b) Block device ops (FAT32) - tentatively working, in same test harness.

        2c) USB Mass Storage. Largely based on manufacturer's example code; builds under GCC/MIPS, along with the above. Tentatively works; see below:

        2d) SD. Fairly simple, draft version. Needs a working example of mainboard to test.

        2e) I/O (incl. power) code. Not in any respectable state of completion, needs mainboard.

        2f) CDC (aka USB Serial, consult standards docs) for 'raw RNG' mode. Not even started yet.

        3) RNG.
        5 RNGs, as discussed previously. Appear to work. 65 remaining. Ordered paste stencils, on the cheap, they should be here by Thurs. of this week. /SMT assembly by hand is a first-class bitch./

        4) Chassis.
        Chassis man (diametric) currently tweaking beam power settings for optimal reproduction of logo; sourcing materials (nylon screws, acrylic.) He awaits exact dimensions (incl. vertical protrusions) of the mainboard and mechanical switch daughterboard.


        So : we are in fact making progress, and a lot of solid work has already been put in. The device is not exactly complete yet, but it's not particularly far off.

        While complexity could still spring from the dark corners - devil in details and all that - the sum total of such dark corners has been steadily decreasing over the weeks. A lot of work has gone specifically into making the design easily scalable, so we could easily transition to mass production once Stan's carpal tunnels finally fall off.

        We do not perceive any serious incentive to rush through any aspect of all this, not only because delivering a quality first product is important, but also because this is in a sense the prototyping of development processes that will happen again in the future, and so time, effort and attention to detail sunk into this project serve not only to make the Cardano a better product, but also to make No Such lAbs a better company. Especially this later consideration is liable to deliver lasting value to the discerning investor.

        We could in fact have opened pre-orders with an incomplete product, at any point during January. S.NSA is not particularly cash starved, and so we enjoy the rare luxury of being able to make the correct choice there. We are nevertheless taking protective measures to help manage the workload - such as hiring a third party to handle the chassis.

        In short : there will be a Cardano, it will be a minutely engineered piece of hardware. The rest is lost in Zooko's triangle.

          Work For Hire Agreement

          This Work For Hire Agreement (the "Agreement") is made and entered
          into as of January the 10th, 2014, by and among

          Ray Russell Reese III (GPG fingerprint 0789 CB4F 508B 384E B74C EFBF
          BDD4 7433 1330 81CF), a mechanical engineer, henceforth indicated as
          "the engineer"


          S.NSA, a Bitcoin corporation, represented by Mircea Popescu as CEO
          (GPG fingerprint 6160 E1CA C8A3 C529 66FD 7699 8A73 6F0E 2FB7 B452),
          henceforth indicated as "the company", as follows :

          1. The engineer will design a casing solution for No Such lAb's
          Cardano product, adequate to be cut in clear acrylic plastic and
          featuring artwork provided by the company in raster etching.

          2. The engineer will release to company all source drawings, files
          and/or data required to reproduce the cases.

          3. The engineer will provide initial prototypes for approval,
          including all fasteners required to assemble the case.

          4. The engineer will provide an initial run of 75 cases, no later
          than January the 25th or in any case within two weeks of having
          received such artwork and specifications as required by 1 above.

          5. The engineer will in the future provide further casings as company
          may need, either manufacturing them or supervising the manufacturing
          process for a fee.

          6. In consideration of the foregoing, S.NSA agrees to pay an upfront
          3.45 BTC fee, as well as 0.003 BTC per case for the run required in 4
          above. Further runs will be negotiated separately, on this basis.
