Clock Kit Round-up – December 2011

Hello Readers

If there’s one thing that I really like it’s a good clock kit. Once constructed, they can be many things, including:

  • a point of differentiation from other items in the room;
  • a reminder of the past (nixie tubes!) or possible visions of the future;
  • the base of something to really annoy other people;
  • a constant reminder to get back to work;
  • a source of satisfaction from having made something yourself!

So just for fun I have attempted to find and list as many interesting and ‘out of the ordinary’ kits¬†as possible, and ignored the simple or relatively mundane kits out there. If you are in the clock kit business and want a mention, let me know. So in no particular order, we have:

adafruit industries “ice tube” clock

Based around a vintage Soviet-era vacuum IV-18 type fluorescent display, the ice tube clock is a rare kit that includes a nice enclosure which keeps you safe from the high voltages as well as allowing the curious to observe your soldering skills. I reviewed this kit almost a year ago and the clock is still working perfectly. Here is a video of the ice tube clock in action:

After some travelling meeting various people it seems that quite a few of us have an ice tube clock. There is something quite mesmerising about the display, perhaps helping to recall memories of our youth in the 1970s and 80s.

nootropic design Defusable Clock Kit

As recently reviewed, this kit allows you to build a simulated ‘countdown’ timer for a hypothetical explosive device that also doubles as a clock with an alarm. For example:

Whatever you do, don’t make a ‘fake bomb’ and leave it out in public! Only bad things could happen ūüôā

ogilumen nixie tube kits

Not a clock kit as such, however they have made doing it yourself very easy with their power supply and IN-12A nixie board kits. We made one ourselves in a previous review, as shown below:

Alan Parekh’s Multimeter Clock Kit

This is certainly one from left field Рusing the analogue multimeters to display hours, minutes and seconds. See Alan describe his kit in this video:

Certainly something different and would look great on the wall of any electronics-themed area or would easily annoy those who dislike the status-quo of clock design.

akafugu VFD Modular Clock

The team at akafugu have created a modular baseboard/shield kit which holds a shield containing four IV-17 alphanumeric nixie tubes to create your own clock or display system:

vfd-7

Unlike some of the other nixie tube kits the firmware has been made public and can be modified at will. In the future different display shields will be available to extend the use of the kit.

tubeclock.com kits

This site has two kits available, one using either four or six Soviet-era IN-12 type nixie tubes:

large_red

… and another kit using the Soviet-era IN-14 nixie tubes:

You have to hand it to the former Soviet Union – they knew how to over-produce nixie tubes. One rare example where we can benefit from a command economy!

evil mad science clocks

The certainly not evil people have two clock kits, the first being the Bulbdial Clock Kit:

This uses a unique ring of LEDs around the circumference of the clock face to create shadows to mark the time. It is also available in a range of housing and face styles. Their other kit of interest is the Alpha Clock Five:

The photo of this clock doesn’t do it justice – the alphanumeric displays are 2.3″ tall, making this one huge clock. It also makes use of a Chronodot real-time clock board, which contains a temperature-controlled oscillator ¬†which helps give it an accuracy of +-/ 2 minutes per year. Furthermore you can modify this easily using an FTDI cable and the Arduino IDE with some extra software. Would be great for model railways (or even a real railway station) or those insanely conscious about the time.

Kabtronics Clock Kits

This organisation has several clock kits which span a range of technology from the later part of the twentieth century. These guys can only be true clock enthusiasts! Starting with the 1950s, they have their Nixie-Transistor Clock:

neononwall

Look – no integrated circuits, leaving the kit true to the era. If you need to hide from someone for a weekend, building this would be a good start. Next we move onto the 1960s and the Transistor Clock:

onwall_l

The 1960s brought with it LEDs so they are now used in this kit, however the logic is still all analogue electronics. However next we can move to the 1970s, and finally save some board space with the TTL Clock:

ttlclock_1721

This would still be fun to assemble but somewhat less punishing for those who don’t enjoy solder fumes that much. However you still have a nice kit and something to be proud of. Finally, the last in the line is the 1980s-themed Surface-Mount Technology Clock:

smtclock_l

So here we have a microcontroller, SMT components, and a typical reduction in board size. Their range is an excellent way of demonstrating the advances in technology over the years.

The GPS FLW Display Clock

Wow Рthis clock makes use of huge Burroughs B7971 15-segment nixie tube displays and a GPS receiver to make a huge, old-style/new-tech clock. Check out the demonstration video:

This thing is amazing. And it is actually cheaper to buy a fully-assembled version (huh). The same organisation also offers another GPS-controlled clock using IN-18 nixie tubes:

nixichron10

Again, it isn’t inexpensive – however the true nixie tube enthusiasts will love it. This clock would look great next to a post-modern vintage hifi tube amplifier. Moving forward to something completely different now, we have the:

adafruit industries monochron¬ģ

Almost the polar opposite of the nixie-tube clocks, the monochron uses an ATmega328 microcontroller and a 128 x 64 LCD module to create some interesting clock effects. For example:

Many people have created a variety of displays, including space invaders and the pong game simulation. The clock also includes the laser-cut acrylic housing which provides a useful and solid base for the clock.

Spikenzie Labs¬†Solder : Time‚ĄĘ watch kit

Technically this is a watch kit, however I don’t think that many people would want to walk around wearing one – but it could be used in more permanent or fixed locations. Correct me if I’m wrong people. However in its defence it is a very well designed kit that is easy to solder and produces a nice clock:

It uses a separate real-time controller IC to stay accurate, and the design However this would be a great suggestion as a gift for a younger person to help them become interesting in electronics and other related topics. The asm firmware is also available for you to modify using Microchip MPLAB software if that takes your fancy.

Velleman Kits

The Velleman company has a range of somewhat uninspiring clock kits, starting with the Scrolling/Rolling LED Clock:

… the 2¬ľ” 7-Segment Digital Clock:

This clock includes the housing and also accepts an optional temperature sensor, and therefore can display this as well. There is also the aptly-named – Digital LED Clock:

mk151

It tells the time and would be useful in a 1980s-era idea of the future movie set. The final velleman clock kit is the Jumbo Single-Digit Clock:

In all fairness this one looks quite interesting Рthe LED display is 57mm tall and the time is display one digit at a time. It is powered by a PIC16F630 however the firmware is proprietary to velleman.

Nocrotec Nixie Clocks

This company has a range of kits using nixie tubes and numitrons (low voltage incadescent displays in tubes). One particularly lovely kit is their IN-8 Blue Dream kit:

in-8-bd-h-side-blue

The blue glow at the base of the nixie tubes is due to an LED mounted at the bottom of the tube. Another aesthetically-pleasing kit is their Little Blue Something nixie clock. Check out their demonstration video:

nixiekits.eu

More IN-12 nixie clocks from Germany, the first being the Manuela_HR. You can buy the kit without an enclosure, or choose from the ‘office’ style:

… or this funky number:

You can specify it with RGB LEDs which colour-cycle to provide the effect shown above. For those not too keen you can also buy the kits pre-assembled. Their other kit is the Sven:

Sven_IN-8-2_720

It is available with IN-8 or IN-14 nixie tubes. The design quality of the enclosure is outstanding, a lot of effort has been made to produce a complete kit that “won’t look like a kit” when completed.

Minty Time

This is a small binary clock kit that fits in an Altoids tin:

This is a nice little kit as it is inexpensive, easy to make and very well documented. You could also mount this in a variety of flat surfaces, limited only by your imagination.

The Chronulator

Here we find a unique design that uses analogue panel meters in a similar method to the multimeter clock detailed previously. Here is an example of the completed kit:

IMG_1113

The kit contains the electronics and meters (or you can delete the meters for a discount if you already have some) however the housing is up to you. Furthermore, this kit has some of the best instructions¬†(.pdf)¬†I have ever seen. They are a credit to the organisation. Our final clock kit is the …

Denkimono

This is another clock kit in the style of ‘suspicious bomb timer’-looking – and it pulls this off quite well. Consider the following video demonstration:

As well as a normal clock it can function as an alarm, stopwatch, countdown timer and lap counter. The instructions (.pdf) are well written and easy to follow. Furthermore the Denkimono is also well priced for the kit and delivery.

Review – nootropic design defusable clock kit

Hello Readers

In this review we examine an interesting, fun and possibly a prankster’s delight – the “Defusable Clock Kit” from nootropic design. The purpose of this kit is to construct a clock that counts down in a similar method to “movie-style” bombs, and it has terminals to connect four wires to the board. When the countdown timer is beeping away, you need to choose which wire to cut otherwise the “bomb” (alarm) goes off.

Furthermore, it also functions as a normal clock with an alarm, so you can use it daily normal activities. And¬†finally¬†it is based on the Arduino system which allows the kit to be reprogrammed at a later date. Now let’s move forward by examining kit construction.

Packaging

The kit arrives in a re-sealable antistatic pouch that can be reused without any effort:

Assembly

Detailed instructions can be found on the product website. The kit has a very clear and well-detailed silk screen on the PCB:

All the parts required are included, as well as an IC socket for the microcontroller:

Moving forward, the first parts to solder in are the resistors:

… then to the other lower-profile components:

… and the rest:

Which leaves us with the final product:

The clock is designed around simple Arduino-compatible circuitry, so if you wish to alter the firmware for the clock or upload your own sketch, you will need to fit the six-way header pins (in order to connect a USB-FTDI cable). As the pins are horizontal and tend to fall over, it’s easier to solder the first pin from the top of the PCB to hold it in place:

… then turn the PCB over and solder the rest.

Operation

Power is supplied via the DC socket on the PCB, and converted to 5V with a typical 7805 regulator. Therefore your input voltage can range between normal levels of 9~12VDC. Once the power is connected you can set the time for the clock and alarm for normal use. However if you feel like some sweat-inducing excitement, connect four wires each between the terminal blocks at the top of the PCB. Then press the red button to start the ten-second countdown. You can also increase or decrease the countdown time.

Your chances of defusing it in time can be quite low – by cutting one wire you can defuse it, by cutting two other wires nothing will happen and the clock keeps ticking – and by cutting the final wire… well, it’s all over. The wires are randomly chosen each time so you can’t predict which will be the correct wire. (Unless you change the firmware). Now let’s see the clock in action:

At this juncture it would be appropriate to warn the users of this kit not to … well, misuse the clock. To be honest I’m surprised such a kit originated from the US in the first place, but then again it never hurts to have a sense of humour. But seriously, to the untrained eye or casual security guard – this kit will look pretty damn real. So no making any mock explosive¬†models with Play-Doh or metal¬†cylinders¬†and leaving them on the train or bus or under someone’s toilet seat.¬†Then again, that would be good for a laugh – so please keep it at home, not in the railway station.

Further expansion

As mentioned earlier this kit is Arduino (Duemilanove) compatible, you can upload new sketches using a 5V FTDI cable or swapping the microcontroller over in another Arduino-style board. You have four LEDs, a 4-digit 7-segment LED module, a buzzer, and four digital I/O pins via the terminal block on the top-right of the PCB which could control external devices. Furthermore you can download and examine the clock sketch to modify or deconstruct it to determine the operation.

Conclusion

Apart from the laughs and possible mayhem you could cause with this, the kit is easy to assemble and works as described. It would make a great present to get someone interested in electronics, or help them with soldering practice. Furthermore it is certainly unique, and would be fun at parties and other events. High-resolution images available on flickr.
