Its minimal style fits with both contemporary and "future retro" decor. Its mix of practical time-telling and aesthetic animations provide a real conversation piece at home or in the office.
A sample of the animations are shown in the listing pictures:
1. big time: a nice big time display
2. game time: each minute, the time is cleared randomly by Pacman, Space Invaders, or falling Tetris blocks (shown w/ a green DOTKLOK available in a separate listing)
3. random dot time: dots randomly fill the screen over 24 hours
4. percent time: percentage of the day passed; one minute is approx. 0.07%
5. basic big time display; shown on a bookcase for scale
There are 14 animations in total, the additional animations are shown at the DOTKLOK webpage: www.technoetc.net/dotklok

Here's a nice review video by a satisfied DOTKLOK owner:
Here's another thorough review:
- 14 user-selectable time animations (can be updated as new ones are released*)
- 24/12 hour modes
- "random mode" can switch animations each day at midnight
- 3.75" x 2.5" (10cm x 6.5cm) LED display
- dedicated real-time clock (RTC) chip keeps date/time with backup battery (included)
- 4 button time/display interface + slide switch for mode selection
- UL / CE power supply included
- open-source code can be modified by owners*: eg. change the button functions and add new time animations
- easily re-programmable: software updates can be uploaded with a standard FTDI cable or USB-to-serial cable*
- totally hackable: circuit board has prototype area and all unused Arduino pins are available; add more switches, buzzers, sensors!
The inspiration for DOTKLOK was to combine in one clock a variety of ways to show time — such as with words, graphics, or retro game displays — while providing a platform on which others can further develop unique timepieces.
The 24 x 16 pixel screen makes for a large, clear time display. A simple button interface is used to set the date and time, and to select from the various display animations. When in “random mode” the clock switches to a different animation each day at midnight so that users can experience a “new” clock each day. The stylish, minimal enclosure is made from laser-cut acrylic panels.
DOTKLOK is Arduino compatible, making it easily customized and updated by owners*. A dedicated real-time clock (RTC) chip tracks the time and date even in the absence of power thanks to a small back-up battery. Also, because of the open source nature of the project, DOTKLOK can be re-purposed for other uses altogether, such as a low-fi video game platform.
DOTKLOK is available as a kit or fully assembled, with either a red or green LED screen. All hardware plans, schematics, source code, and assembly + useage instructions are available from the DOTKLOK webpage:
The kit comes includes everything needed to build your DOTKLOK -- excluding tools -- all high quality parts and hardware, sourced from industry-leading suppliers. It's easily assembled with beginner's soldering experience since all the electronic parts are through-hole. The entire clock can be put together in a few hours (or as little as 90 minutes for experienced kit builders) by following the illustrated assembly guide.
This listing is for a RED / KIT. Check my other listings if you are looking for a green or assembled DOTKLOK.
Thanks for your interest!
Title: DOTKLOK (open, unnumbered edition)
Materials: LEDs, custom electronics + hardware, acrylic panels, power supply
Dimensions: 7" x 5.5" x 2" (18cm x 14cm x 5cm)
Power consumption: 2 watts (that's right, it would take 30 of these to use the same energy as a 60W bulb!)
* modifying the clock programs requires an FTDI cable or 5V USB-to-serial adapter which is not included; full details at the DOTKLOK webpage:
