194 Transistor Clock Will Blow Your Mind

January 11, 2010 by 59 Comments

It’s nice to have tip put on our desks that we think everyone, yes everyone can enjoy. The Transistor Clock is just as its name implies, A clock that doesn’t rely on ICs. 194 Transistors, 400 resistors, 566 diodes, and 87 capacitors are all that makes this clock tick – no programing, and most importantly no Arduino. The clock is offered as a kit, but there is a complete parts list and manual (including debugging help) so anyone can build (and fix) their own. The Transistor Clock might even beat out the VFD Clock and the Word Clock on the ‘pure awesome’ scale, tell us your favorite in the comments.

VFD Clock (ends The World)

December 26, 2009 by 15 Comments

We honestly thought [Jason’s] VFD clock was some form of new terrorist attack when we came across the RSS. Thank goodness our relations with Russia aren’t as MAD as they used to be.

The main components are an IV-18 VFD with a MAX6921 driver, which to an untrained ear do sound surprisingly threatening. However an Arduino settles our hearts down and assures us this only has as much potential as blinking a VFD. While the main code, schematics, and CAD aren’t available (open source coming to a theater near you soon) at the moment – you can check out [Jason’s] inspiration, the Ice Tube Clock, which runs many of the same components.

Enjoy a video of it in action after the break. We love the ‘countdown’ feature the most.

Clocks That Only A Geek Could Love

December 18, 2009 by 15 Comments

Alpha-Geek Clock

Oh this one’s good! This clock has a built-in WWVB receiver to make sure the time is always accurate. But with just one LED as the display we wish you good luck when reading it! A whole bunch of info (time, day, year, etc) is blinked out in binary encoded decimal. [Thanks Tymm]

Standard Time

Manual labor. This clock is an art installation in Rotterdam. In the video you can see that workers changed the segments of a four-digit display every minute over a twenty-four hour period. Since they filmed it we’d expect the ability to turn this into a video clock like the one we saw last week. [Thanks David]

International Clock

Low-tech but highly creative. The instructional video uses basic geometry and the workings from a cheap clock to craft an international clock. There are twelve labels corresponding to different time zones. Put the zone you want up and read the clock as normal. [via Red Ferrett Journal]

Princess and the Pea

There are few who will agree to have an air tank as part of an alarm clock. The Princess and the Pea concept uses compressed air to inflate an exercise ball in between the mattress and the box spring. Watch this video to see how it will roll you out of bed if the hissing air sound didn’t wake you first. At least it’s more gentle than the pneumatic alarm clock from last June. [via Neatorama]

Word Clock Redux

December 11, 2009 by 21 Comments

[drj113] wrote back to let us know his latest version of the infamous Word Clock, now in Arduino flavor. You may remember when we originally showed you the Word Clock back in September, while much hasn’t changed, he’s added and modified a few things to make it more user-friendly. Most notably is the use of Arduino instead of PIC, while some commentators will complain this as a waste of an Arduino, it is extending the project towards those who are less technically inclined. Other changes include a new case, dedicated time changing buttons, and blue LEDs (and who doesn’t love blue).

We would also like to give [Alex], one of our commentators, a shout out with is QlockTwo. Same Word Clock concept, but used acrylic, paper sheet, and stickers to produce a much smoother look.

Update: It would appear we’ve made a slight mistake, the original creator of the QlockTwo is actually [Ruud Burger], not [Alex]. Thanks [Ruud] for clearing that up.

Bulbdial Clock Kit Released

December 10, 2009 by 12 Comments

Evil Mad Scientist Laboratories has just released a Bulbdial clock kit. This has come a long way since their first prototype, featuring three PCBs to carry the 72 charlieplexed LEDs. For accuracy they’ve included an optional header for a ChronoDot precision RTC.

With a great looking face and laser-cut acrylic case available, this may soon adorn our mantle. Time to write that letter to Santa…

Update: [Windell] of EvilMadScientist.com posted some video of the clock in action.  We’ve embedded it after the break.

Hackaday Links: December 7 2009

Ah the beauty of watching molten solder pull SMD components into place. Yeah, we’ve seen it before, but for some reason it never gets old.

The glory days of wardriving are certainly behind us but if you’re still hunting in certain areas for access points you can leave the laptop at home. A homebrew program called Road Dog can turn your PSP into a WiFi search device. You must be able to run custom code to use this app.

Ferrofluid is our friend. But having grown up watching the Terminator and Hellraiser movies we can’t help being a little creeped out by the effects seen in this movie.

Follow along with the NASA astronauts in this 20 minute HD tour of the international space station. It’s a cramped place to live but we can’t help thinking that it looks incredibly clean. After all, where would the dirt come from?

How are your woodworking skills?  Can you take a wooden block and turn it on a lathe until you have a lampshade 1/32″ thick? We’d love to see how these are made, but imagine the artist’s reaction when hours of labor are ruined by a minuscule amount of misplaced pressure on a carving tool. Patience, we’ll learn it some day!

This video from the past that is about the future of  travel does leave us wondering why our cars don’t have built-in radar for poor visibility? We’ve already realized the rear-view-mirror-tv-picture, but we’re going to need your help before the flying police/fire/ambulance-mobile is a common sight. Oh, the fun of seeing a high-tech push-button selector 3:30 into the video. Perhaps the touch-screen was a bit beyond the vision of the time.

Sometimes you have so many servants you need to find creative things for them to do. Only the most discriminating of the super-rich employ a person whose sole responsibility is to erase and redraw the hands of a clock each minute. This video is obviously a result of the global recession as the live time-keeper has been let go; a looping recording took his job!

Last time we checked in with [Marco Tempest] he was syncing video over multiple iPhones. Now he’s at it again with an augmented reality setup. A camera picks up some IR LEDs in a canvas and translates that into information for a video projector. We’d call this a trick, but it’s certainly not magic.

Magic Clock Knows Your Location

Straight out of the fiction of Harry Potter is The Magic Clock. Just like in the novel this clock (is it still a clock even thought it doesnt tell time?) shows the current location of family members, from home to the doctor’s office, even to mortal peril (We hear its nice this time of year).

The clock hands are driven by 4 separate servo motors, which are maintained by an Arduino. The location of family members is updated wirelessly via Twitter. We think a script written for each member’s GPS enabled cell phone might be more trustworthy, but it seems to be working fine currently.
