  • Oscilloclocks keep time indefinitely, without needing any adjustment…

    Such unique time displays… and they’re accurate!

    How?

    By automatically synchronising time against a reliable external time source, at regular intervals.

    The current standard synchronisation sources are GPS satellites (via either onboard or external receivers), or NTP servers (via WiFi).

    The Oscilloclock Wave – a WiFi dongle to pull time (and other things) from the Internet

    And for the most decadant timepiece, there is an even cooler option: a rubidium time source. You can gain/lose at most 2 milliseconds per year!

    Even an Atomic Oscilloclock is an option.
    Because We Can.

    But let’s take a more in-depth look at the two standard options:

    GPS – stand-alone & reliable

    Yes, that’s right – you can get extremely accurate time from GPS satellites!

    The long-standing favourite amongst Oscilloclock aficionados is the External GPS (Garmin ‘puck’) option. Features include:

    • a long cable that allows positioning for best sensitivity
    • an inbuilt magnet for attaching to metal beams
    • a gorgeous connection system – satisfying haptics and robust locking

    Of course, we also have the internal GPS option, where the GPS receiver is mounted on the Control Board itself. This is super nifty, if there is no concern about satellite signal strength where the clock is placed. (This is very rarely an issue. These receivers are extremely sensitive!)

    Can you spot the onboard GPS module in this gorgeous OscilloBlock?

    Geolocation

    The GPS option allows the Oscilloclock to obtain not just time, but also geolocation information from satellites.

    Okay, it’s true that Oscilloclocks are generally placed in a fixed location, so showing the clock’s location on a map might not be very useful…

    Think again!

    How about an OscilloGlobe, to warm up your long-distance relationship? Plot you and your friend’s Oscilloclocks on a spinning globe, and count down the hours til you meet again…

    Or perhaps you fancy an OscilloWear? A wearable Oscilloclock, sporting a miniature CRT and it’s-only-possible-in-Japan miniaturised circuitry! Complete with GPS.

    An OscilloWatch capable of recording your sporting activities? With OscilloMaps that guide you to the nearest Oscilloclock retailer? And of course: the OscilloPhone, or oPhone for short?

    Ahh, we could have so much fun making devices that use location data…!

    NTP – low-cost & extensible

    The Oscilloclock Wave is the glorious device that allows your Oscilloclock to connect to a Wi-Fi router and pull in time from NTP (Network Time Protocol) servers.

    It comes in different forms, both external and internal:

    The Oscilloclock Wave requires a WiFi connection (and Internet), and some initial configuration – it doesn’t just work straight out of the box, in a standalone way like the GPS option.

    However, the Wave has a distinct advantage: it can access various APIs (think: providers of data over the Internet) to pull in and display all kinds of information!

    Want to display the current weather on Mars? The latest news? Stock prices ticking madly? All this is technically possible… and can be implemented upon request.

    To date, we’ve used this capability in several themed Oscilloclocks: the Astro Clock (pulling in sidereal time from an API) and the AfterShock Clock (pulling in earthquake data).

    Sidereal time, for all the astronomers out there!
    Earthquakes are disasters – no joke. But a semi-live visualization in Lissajous figures? Too cool..

    Not saturated yet? For more on Wifi based synchronisation and various configuration options, see the support page: Oscilloclock Wave.

    The No Synchronization option!

    Do you want to take your Oscilloclock off-grid? We’ll craft you a unique clock powered by wind, solar, USB-C power bank, or even a hamster wheel. (We can even procure extremely low-power CRTs!) But to go fully off-grid, you won’t want to use GPS or WiFi.

    A (more likely!) scenario is simply that signal strength is just too poor. Maybe your clock sits in a basement 3 stories below ground…

    For such cases, you can set the time manually in the Time Setting screen. Once set, an on-board quartz oscillator then maintains reasonably good time (in the order of seconds per month). You’ll want to adjust it occasionally!

    Decisions, decisions…

    Must it be one OR the other? Can’t a gadget lover have their Oscilloclock source data of different types from both GPS and public APIs over the Internet?

    Sadly, no – not in the current Control Board revision. This supports only a single interface, which is occupied by either the GPS or the Wave module. (We have multiple input capability on the long to-do list!)


    Oscilloclocks are beautiful and entertaining. There’s that warmth of the CRT filament and the brilliance of coloured phosphor excitation, combined with all the features of our digital era.

    But above all – they are clocks! Hope you enjoyed this treatise on how time is managed.

  • Quake News!

    Fake news – a common keyword these days. Fortunately, Oscilloclocks do not display fake news. But wouldn’t it be handy to see quake news on an exotic scope clock? This is the challenge [Atif] gave me – and one year and many grey hairs later, here is the result: The AfterShock Clock!

    This custom-crafted Oscilloclock Core Duo assembly is a unique first in several ways:

    1. It’s the first scope clock ever that pulls in and displays real earthquake data!
    2. It’s the first scope clock ever that puts a dual-beam CRT to good use – one beam for the clock display, and the other for the earthquake and map overlay!

    Earthquake display

    The AfterShock Clock’s WiFi module connects at regular intervals to two public APIs (servers) to collect the latest earthquake events. It then feeds earthquakes to the clock’s quake gun controller, rotating quakes every 30 seconds. Cool!

    (Note: flickering is due to camera effects and is not visible to the human eye)

    Of course, there is the usual wide variety of standard clock screens to cycle through! The quake map’s beam is automatically dimmed for most of the screens, giving a soft ‘watermark’ effect.

    Dual-beam CRT

    The E10-12GH CRT used in this clock is certainly not mundane!

    Beautiful spiral PDA lets you really see inside the cavity!
    Nothing beats a dual-gun CRT for intricacy… (except a quad- or pentuple-gun CRT!)

    Oscilloclock Core Duo

    Atif wanted to create his own case, so he initially asked for an Oscilloclock Core. But currently a single Core set does not provide control, deflection, and blanking circuits to drive TWO electron guns… So he had two choices:

    1. Wait an eternity for me to redesign the boards to fully support dual beams.
    2. Get started now! Simply put two Core assemblies together, with some degree of inter-control and removing any redundant circuits.

    Atif chose the latter – and the Oscilloclock Core Duo was born!

    WiFi setup

    Setting up the WiFi connection is easy – just connect a device to the clock’s administration SSID and pull up the admin page. (To foil any would-be hackers out there, the admin SSID is available only for the first 5 minutes after power is applied.)

    Then, access the admin URL and configure the connection to your home router:

    There are a million other advanced settings to tweak things such as quake polling interval, quake magnitude filters, maximum quake age before purge, and other geeky aspects…. See the Support page.

    Oh, I forgot to mention – the clock also synchronizes time against an NTP server, eliminating the need for a GPS module.


    Like what you see?

    Do you go for electron guns? idolize intricate electrode assemblies? Have a filament fetish? Or just want some quake news? This kind of clock might fit the bill. Let me know!
