Hack a Day
[Craig's] color clock really came together quite nicely. The majority of the body is acrylic, with two large clear squares and a pair of colored discs. All are held in place by a ring of hardware with spacers in them, and the RGB LED strip that is used to display time and date wraps around [...]

That awful buzzing/beeping beside the bed in the morning might not seem so bad if it were a cascade of bubbles instead. At least that’s what [Will] is hoping for. He took a child’s toy and turned it into a bubble blowing alarm clock. We’re guessing you’re not going to be too happy with the [...]

+ So at first glance we were thinking there wasn’t much special about this clock. It’s based on an Arduino and displays the time using a character LCD screen. But then we realized that there’s no battery-backed RTC and no buttons. How the heck do you set the time on this thing? [Mossblaser] is using [...]

Hack a Day
This wristwatch is hiding a lot of features in its hardware and its software. It’s called the TicTocTrac and it’s a Senior project for a pair of students at Cornell University. Judging from the sheer volume and quality of the project documentation we wonder if someone has a science writing career ahead of them? Be [...]

Hack a Day
[Haris Andrianakis] just finished building this very clean-looking vacuum fluorescent display clock. It shows six digits using IV-11 tubes, and also has a half-dozen RGB LEDs to spice things up (check out the video after the break for an example). An ATmega168 drives the device, controlling the display and serving as a battery-backed real-time clock. As with [...]

[Professor Shadoko's] Mac Mini died. But since the case designs on Apple products are half the reason to buy them, he decided to reuse the enclosure by turning it into this clock (translated). As with the binary clock we saw yesterday, this one uses a bunch of LEDs to display the time, but it does it [...]

Hack a Day
Maybe it was a language barrier he ran into, or possibly an inclination to do things the hard and smart way, but we really like [Alessio]‘s take on building the display for his word clock. Instead of relying on a pre-designed word layout, he made his own word pattern with a genetic algorithm. While looking at [...]

[Vinnie] has a wonderful old clock from his grandmother; it’s an exquisite antique with a real mechanical movement and a charming set of bells that ring every hour. Unfortunately, those chimes are a bit of a disturbance to neighbors at 2 o’clock in the morning. Previously, [Vinnie] had been stopping the clock every evening, and hoped [...]

Hack a Day
We see plenty of clock projects come through, but usually it is their visual or mechanical design that stands out. The DCF-77 LED PIC clock is fun because it is synchronized with the Atomic clock in Braunschweig Germany. The clock picks up the radio signal at 77.5 KHz known as DCF77, and that’s where it [...]

Although [Serokoy] is not thrilled with the outcome of his Nipkow disk clock (translated), but we really enjoy it. It uses the Persistence of Vision concept to create a light display from a rotating disk. We’ve come across a lot of rotating disk clocks. Several were based off of the platters of a hard drive, using [...]

A long time ago and on a scrounging trip he barely remembers, [Victor] bought a quartet of digits from an old Dutch Railways clock. These antique displays used a strip of plastic coated cloth that rolls around itself with the help of a motor to display the digits 0 through 9. It’s been many years, but [...]

Since [th3badwolf] realized a wrist watch is the ultimate men’s fashion accessory, he’s been trolling around eBay looking for a nice looking, but still inexpensive wearable chronometer. The Fauxlex brand isn’t normally regarded for accurate time keeping, so he decided measure the accuracy of his off-brand watches in a really clever way. [th3badwolf] had a camera [...]

Hack a Day
[Karl] needed a programmable real-time clock for one of his projects. He considered adding an RTC chip, LCD screen, and some buttons for use with a microcontroller. That’s not necessarily hard, but it takes time and can be considered a project in itself. Instead, he headed to the hardware store to look for a cheap [...]

This hard-drive based POV clock is a treasure trove of great design choices. Now, we’ve seen a bunch of spinning clock builds. Several of the hard drive versions use slits cut in the platters to create a display by illuminating an LED behind those slits at just the right moment. This is a similar idea but [...]

Packet Storm Security Advisories
The IE9 (platform preview) Javascript Math.random implementation is vulnerable to seed reconstruction. The seed reveals the computer's boot time (and on Windows 7 - also CPU clock speed). These can be used to finger-print computers and track users within the same Windows session even if they close and open their IE9 (platform preview) browser multiple times. Interestingly enough, this technique also provides some information regarding the client hardware (namely clock source and possibly CPU clock speed), and may be used to detect virtualized machines "over the web". Additionally, the Math.random implementation is flawed in such way that it returns non-uniform values (this holds for IE9 beta as well).

We asked for information on your projects that use this method and we got a lot of comments and tips. Today we’re sharing [Doug Jackson's] method which he used in his word clock. The [...]

The IEE clock looks somewhat un remarkable at first glance. Upon closer inspection though, you’ll find out that there are 12 light bulbs crammed in there for each digit. The bulbs sit behind a curved lens with the numerals on it. When the appropriate one is lit, it projects the number on the front of [...]

[Alan] is branching out beyond the Arduino with this clock. He’s still using the same code but built this board around an ATmega328 and the components he needed, saving his Arduino board for further development. The concept uses a character display housed in an old iPod Touch case. The build relies on an infrared sensor [...]

[Lucassiglo21] developed this logic clock without using a crystal oscillator or a resonator. Instead, he’s letting the incoming electricity keep the time for him. The supply is AC at 50 Hz so he’s using some 4017 decade dividers to reduce that down to a 1 Hz signal. From there it keeps track of the ticks [...]

This clock requires no microcontroller. It’s actually a digital logic counter that functions as a timepiece. [BlackCow] used six decade counters to track seconds, minutes, and hours. The output is displayed on four 7-segment digits using BCD-7-segment decoders that you can learn about in our binary encoded decimal post. The actual timekeeping is done by [...]

This gorgeous persistence of vision clock was built a couple years back by [mb1988]. The housing is made of acrylic with a hard drive motor mounted in the center of the back panel to spin a PCB. The two-sided circuit board is home-made and includes a battery for power, ATmega32 for the brain, 32 LEDs, [...]

We’ll just say, [Kenneth] really likes clocks. His most recent is a pure 7400 series TTL based one, ie no microcontroller as seen in the past, here, here, and here. The signal starts out as a typical 32,768 crystal divided down to the necessary 1Hz, which is then divided again appropriately to provide hours and [...]

[Brian] wrote in to show us a site he’s been working on for a while. He’s been building a tube clock database. We didn’t realize there was actually a big enough draw for such a site, but we have to admit that we spent more than a few minutes browsing through the different clocks. There [...]

Strobeshnik is a somewhat different twist on the hard drive clocks we’ve seen in the past. Though still technically using a POV effect, the Strobeshnik displays the numerals instead of a line. By altering strobe timing of an LED behind a platter with the numbers cut into it, he can display whichever number he wants. [...]

Space Invaders came out in 1978, six years after Pong. That means this Space Invaders clock uses newer technology, right? Nope, it’s the same hardware as the Adafruit Pong Clock with some updated firmware. Still, as you can see after the break, the effect is pretty nice. Pong was cool, but having a clock that [...]

[PT] let us know that Adafruit Industries has just release a pong clock kit. The $80 price tag might seem a bit steep but it does come with a custom-ordered KS0108 display in order to get white on black like the classic video game, as seen after the break. Also included is the laser-cut case, [...]

[Michiel], unsatisfied by his Phillips wake up light, decided just to make his own. He really wanted programmable weekend alarms as well as an easier to find snooze button. At first, his circuit was not reliable enough, losing several minutes per hour, but he gutted another alarm for the 1Hz crystal. After some carpentry, his [...]

[Andrew] built this pong clock over the span of a couple of days. The PIC 18f2520 he used can serve as a real time clock with the addition of an external clock crystal. His project proves the usefulness of an oscilloscope as poor board layout caused interference in the crystal connections, something difficult to troubleshoot [...]

[Kenneth Finnegan] quenches our clock-a-day compulsion with his Arduino based binary timepiece. The clock uses a 5×7 LED matrix as a display and shows month, day, and time. He sourced a DS3232 real-time clock which automatically compensates for temperature to achieve very accurate time keeping. We like the super-cap circuit he added to keep the [...]

[Kieran] let us know about his hybrid analog/binary clock. The circuitry behind the clock is nothing too new. An Arduino combined with a Chronodot to produce an accurate clock. What we really enjoyed however was the creative implementation of an old British Telecom Linesman’s Multimeter as the case. The analog meter acts as the seconds [...]

[Mahto] bought a digital picture frame but the image quality turned out to be terrible. He decided to turn it into a clock in a unique way. He loaded up 720 images, one for each minute in a twelve hour period. He then used an Arduino to simulate a button once a minute, cycling to [...]
