TicTocTrac: track your perception of time

Monday, May 14th, 2012

TicTocTrac Wristwatch

Brian Schiffer and Sima Mitra, from Cornell University, propose a very nice wristwatch that allows you to keep track of your time perception, using a method known as duration production: TicTocTrac.

Human perception of time is typically distorted, due to the different amount of information and experiences acquired everyday. TicTocTrac lets you to estimate your own perception, first by signaling the perceived duration of a given event and, then, by comparing it with the actual event duration. Finally, all the information can easily be saved to a micro SD card.

The hardware is based on a Atmega32u4, a DS3234S real-time clock and several leds to display time, while the software part is mostly based on Arduino’s DS3234S RTC library.

Retro Pinball Clock Hack

Wednesday, October 5th, 2011

[Alan Amon] posted a cool vintage hack on Instructables, adding GPS-based clock funcionalities to a Bally Wizard pinball.

Pinball machine will automatically power up at the preset time each day and then resets to display the current time, the year, the time the alarm is set for and the date month/day. Then as long as the GPS has a signal the time will update once a minute for the rest of the day.  At the time you would like to go to bed the Arduino will cut power to the game and it will remain off until the alarm time. Should you have a power failure in the night the machine will not lose it’s settings. If power is restored prior to the alarm time the machine will wake up as normal, otherwise the machine will wake up once power is restored.

If the game is powered on because it is not yet bed time and it is after the alarm time then at 12am, 1am or 1pm the game will do a full reset. This makes sure the clock hasn’t gotten off due to a stuck score reel, keeps the time in a 12 hour format and keeps the date display up to date.

Have a look at the “cool features” and “coolest features” in the instructables article

Heart Spark Logging & Blinking Your Beat

Wednesday, February 2nd, 2011

Sensebridge is a little board that logs up to 61831 heart beats, about 14 hours of data. It is based on a atmega 168, a Real Time Clock, and 512 Kbit EEPROM. And it’s released open source.

The Heart Spark is a heart-shaped pendant which flashes little lights (light emitting diodes, LEDs) in time with your heart beat. A polar chest strap with transmitter (sold separately) is used to measure your heart beat, which is transmitted wirelessly to the pendant. An arduino-compatible circuit captures each beat as it happens and flashes LEDs (later versions will log data to an onboard EEPROM – see below). The pendant is carefully designed to maximize its visual appeal, including symmetry and optionally a high-gloss epoxy coating (as pictured to the right). A CR2032 coin-cell battery provides 8+ hours of battery life. Two small switches on the back allow selection of operating mode:

The Equinox Clock

Wednesday, September 22nd, 2010

The Equinox Clock is an Arduino-based creation that lets you tell the time with a rainbow-hued ring of LEDs illuminating your wall. Its hollow circular shape looks a lot like that bladeless fan, the Dyson Air Multiplier.

[BranKnaapen], who made it, explains how the clock has been done.

Alarm clock that finds perfect time to wake up

Monday, July 19th, 2010

Wow. Original Arduino-based alarm clock “Alarm clock that finds perfect time to wake up”. I don’t think the project (code and schematics) is going to be posted. Still a nice project to be inspired of: the alarm listens to a numeber of sensors around the house and monitors the quality of your sleep.

Probably you know the feeling when you get out of bed on the wrong side. The only way to avoid this is to get up at the best time of sleep rhythm. How to do that? The only way is to keep track of various parameters of sleeping human and then decide when it’s time to get up. So the following project is what it tries to do. It is based on Arduino and measures various parameters like quality of air like temperature, humidity, dew point, light level and of course tracks time along with sleep pattern.

I totally need one ;)

Scrolling text on the Dual RG matrix shield

Friday, March 19th, 2010

Very nice implementation of the “Dual RG matrix shield” of WiseDuino‘s IllyClock.

Now you can edit a scrolling text to diaply longer statements. Code ready.

Simple Binary Clock for Arduino

Wednesday, March 3rd, 2010

Binary clock using Arduino.



If someone wants to make the circuit all it is is each LED is connected to a digital pin from 1-13, and 2 tact switches connected to analog 0 and 5. The LED numbers are the right most column bottom LED is LED 1 and counts up. The next column over would be LED 5 and counts up and so on.

here’s the code.
