The “AlarmTock”, A Chumby Hacker Board Alarm Clock

August 28, 2011 by Jeremy Cook 6 Comments

[Thomas] wrote in to tell us about his latest project, the “AlarmTock”. Like many hacks, this was inspired by some outdated hardware, a radio alarm clock from 1992.

After finally getting fed up with his old alarm clock, [Thomas’] wife purchased him a new one for around $10 from a local retail store. Although most likely an improvement, [Thomas] wondered why after so many years he still had to listen to either an annoying “beep” sound or whatever song the DJ on the radio decided to play.

In true hacker form, he decided to do something about it. [Thomas] crammed a [Chumby Hacker Board], which has much of the same hardware as the [Chumby One] device, into his clock radio. RSS-driven text-to-speech was used to tell him exactly what he wanted to know every morning. A sample .wav file is provided as well as the python script used to execute his morning wakeup routine.

Do You Have What It Takes To Make Lumber Keep Time?

July 31, 2011 by Mike Szczys 20 Comments

[Frank] sent in a link to this fantastic wooden clock. The design was dreamed up by [Clayton Boyer] and he’s got full-sized templates for sale on his site. We’ve marveled at his creations in the past, having featured his useless machine that was made from wooden gears. This “Bird of Paradise” clock steps up the complexity quite a bit, creating a timepiece without a case to show off the beauty of all of those teeth.

We wondered what goes into building one of these yourself. From the FAQ page it seems you could get by with a scroll saw, drill press, Dremel, and sander. That’s the medium-tech method, but you could opt to scan the plans in order to laser cut your parts, or just use hand tools. But in addition to building tips, there’s advice on how to fine tune clocks that don’t want to keep running, thoughts on finishing the wood parts, sanding, tweaking the teeth, and much more. It’s no secret we have a love for digital clock projects, but there’s something very seductive about a design like this that uses no electricity. Don’t miss the clip after the break to see what we mean.

Clocks Built From Old Aircraft Surplus Parts

July 25, 2011 by Mike Nathan 26 Comments

A few years ago, Tube Clock forum member[Sine1040] bought a set of four brand new aircraft indicator units that were built some time in the early 70’s. He had no idea what the units were actually used for, but he did know that he could repurpose them into some pretty slick looking clocks.

He disassembled all four boxes and between them, scrounged enough parts to build three clocks. After gutting the clocks and rearranging the digits, he built a timekeeping circuit using an ATMega8 which is clocked by a DS32 oscillator.

While the time is displayed using the large projection-style digit displays, the seconds are ticked off in the left-most analog meter. Minutes are also represented in the clock’s right-most analog window, swinging the needle from top to bottom as each one passes.

[Sine1040] paid special attention to keeping the boxes looking as stock as possible, with the only external modification being a power plug installed in place of an old grounding screw. The clock is definitely a different take on keeping time, and we think it looks great.

Klout Klok Tracks Your Popularity, Time

July 21, 2011 by Brian Benchoff 7 Comments

[Fabien Royer] has been playing around with Netduinos and he just came up with a really awesome project that will display the time and social media popularity. It’s a very nice build, and we’d guess that his social media influence is going to go up very shortly.

Klout is a service that connects to your Facebook or Twitter profile and tells you how much influence you have on a scale of ~~1 to 100~~ (possibly 10 to 100. see this). To build the Klout Klock [Fabian] used a Netduino Plus, a good choice because of the integrated ethernet port. The Netduino connects to the Klout API to either satiate vanity or admit prestige. The display is an adafruit TFT screen.

DIY Clock Replica Is Better Than The Real Thing

July 11, 2011 by Mike Nathan 14 Comments

After seeing the TIX clock for the first time, [Gweedo Steevens] really wanted one, but wasn’t interested in paying the seemingly high asking price over at ThinkGeek. He figured it wouldn’t be too incredibly hard to build his own, so he decided to give it a shot.

The clock relies on 27 LEDs to display the time, which were multiplexed to make the most of his ATMega16 microcontroller’s available IO pins. Once he was happy with how things functioned on breadboard, he migrated the LEDs to a piece of perf board, and etched his own PCB for the controller circuit.

He used an office overhead lighting grate to separate the LEDs, providing nice uniform light segments. He put a piece of clear perspex on the front to cover the LEDs, but later switched it out for a much darker piece, for better daylight viewing.

The finished product is fantastic, and in our opinion looks even better than the retail version – awesome job!

Slick 16-segment POV Hard Drive Clock

July 10, 2011 by Mike Nathan 20 Comments

Hackaday reader [svofski] sent in a fantastic looking hard drive-based POV clock (Google Translation) created by a maker in the Sichuan province of China. The clock, like the one [svofski] built, relies on LEDs placed behind the spinning platter to create the POV effect.

Quite a few carefully placed cuts have been made to the platter, which make up the segments required to display both numbers and letters of the alphabet. This isn’t a simple 16-segment POV display however. The font uses a lot of sharp edges and odd segment lengths, so we’re guessing that quite a bit of care was taken in the production of this clock.

You can see a demonstration of the clock in the video embedded below, which shows off its ability to display numbers, text, as well as a handful of simple patterns. It looks like there are some details available on the designer’s site, however it is all in Chinese, and Google’s translation is questionable at best. If only we knew someone that could give us a hand with deciphering the inner-workings of this clock…

10,000 Year Clock Sounds Like An Indiana Jones Flick – Makes Us Wonder If We’re Being Trolled

June 23, 2011 by Mike Szczys 54 Comments

So you hear that someone is building a clock that will run for 10,000 years and you think ‘oh, that’s neat’. Then you start looking into it and realize that it’s being built on a mountain-sized scale in a remote part of the US and things start to get a bit strange. As much as it might sound like a Sci-Fi novel (or some creative trolling), the Long Now Foundation is in the process of building and installing a clock that will chime once per year for the next ten millennia.

The clock, currently under construction will be over 200 feet tall, residing in a shaft drilled in a limestone mountain in West Texas. The allusion to [Indian Jones] sprung to mind when we read that the shaft will be drilled from the top down, then have a shaft with a robot arm installed to mill a spiral staircase into the stone walls. And this isn’t the only clock planned; a second site in Nevada has already been purchased.

There are a lot of interesting features, not the least of them is a ‘chime engine’ that plays a unique tune each year that will never be repeated again. [Alex] sent us the original tip to a Wired article that covers the project in incredible detail. But we also found a SETI talks video that runs for an hour. You’ll find that embedded after the break.
