  1. Have you seen those silly "viral" videos when one turns on the ignition in some prohibitively expensive car and the voice says some kind of greeting? I did and it got me thinking - how much is this "feature" overpaid for?
    Since I had some time on my hands, I set out to check if I can build one on the cheap for my #motorcycle and apparently I can ;)
    Essentially the criteria I set for myself were:
    - cheap.
    - as much waterproof as possible.
    - zero maintenance

    The first idea was to slap some kind of PiZero and program it, but I decided against, there has to be something simpler.
    Enter Adafruit.
    I got one of their SoundFX boards with 2MB of RAM which was enough for my .ogg sample. Some trial & error and a bit of research later is what you can see on the video:
    - Voltage converter 12V->5V. I could possibly replace that with a simpler element but I had one at hand.
    - Timed circuit switch working in "open once on V+ for the time set".
    - Adafruit SoundFX board set to "trigger once" mode.
    - Adafruit amplifier board (+6dB - +24dB)
    - Speakers (4 Ohm) scavenged from a dead sound bar.
    - Sample sound of my choosing taken from the Mechwarrior 2: Ghost Bear Legacy game, as it is the greatest game ever, period.

    What's left to do: solder it all up together and pack into the speaker enclosure; add a fuse to the power wire; connect it all to my #F750gs

    If anyone is interested in exact description of steps and configuration and board models, please let me know, I am happy to provide more details.

    Overall cost of the whole (minus the speakers, I paid for the whole sound bar some £30 10 years ago): £27.

  3. Another ride training for my IAM certificate. As usual, very demanding with lots of useful, practical feedback from my Observer. I think I like the habit of pushing myself a bit every time I ride in order to be a better and safer rider. Today I ache again, bike needs another wash but that smile visible on the photo stays on.
