The pictured PrismaChron and PrismaChron PCB is a prototype version and does not represent the final look of the clock. The final PCB will be black with orange silkscreen.

Fully Assembled clocks are available, no soldering required! Check the support levels below and in the drop-down at the right, below the "Support Now" button.

Overview

The PrismaChron Clock is our take on time as color. The display consists of three RGB LEDs, one each for seconds, minutes and hours. As each value progresses through time, its LED slowly fades through the spectrum from red to violet, and everywhere in between.

Details

Each of the three LEDs has a custom, 3D printed, white diffuser for normal use of the clock. As an alternative, the diffusers can be removed and the clock can instead be set facing a surface to reflect off of. If this mode is used, the A button can be pressed to switch which side of the clock seconds and hours is on.

It can be set either manually with the A & B buttons or via a serial connection to a computer and a simple console application (FTDI cable not included).

Platform

Warning: Nerd Content:

The PrismaChron is completely compatible with the Arduino IDE - just select "Arduino Duemilanove w/ ATMega328P" - and can be reprogrammed using any FTDI serial cable or ISP like the AVRISP MkII or USBTinyISP.

It comes with an on-board DS1307 Real Time Clock chip, for accurate timekeeping, and a battery backup good for about seven years so you won't loose the time if main power is lost.

Power is provided via a miniUSB port and included 3' cable that can be used to power it off of any computer, USB hub, or USB wall adapter.

What's in the Box

• PrismaChron PCB*
• All required ICs, resistors, capacitors, etc.*
• 2 nylon standoffs to stand the clock at an angle
• 3 White LED diffusers
• 3' miniUSB cable
• Free Toy!

*Unless you opted for the fully assembled clock, in which case you will receive a completed clock. Just plug it in and enjoy!

Purchase Options

For this fundraiser, we are offering four levels of support for the project.

Level 1: PrismaChron Kit - $25

For the electronics lover who's handy with a soldering iron or even just getting started. You will get all the components to build the complete kit, including a microcontroller pre-flashed with firmware. This is a super-easy kit that can be completed in less than 20 minutes (for a pro), but is also quite suitable for someone who's just learning.

Level 2: Fully Assembled PrismaChron - $35

Don't know how to solder? Don't have the time? Let us do it! Same great kit, without all the solder fumes and burnt fingers.

Level 3: PrismaChron Kit & Binary Epoch Clock Kit - $48

You'll get the PrismaChron and our Binary Epoch Clock kits at a discount. Tell time in not one but two great and geeky ways!

Level 4: Fully Assembled PrismaChron & Binary Epoch Clock - $65

We love the smell of solder in the morning. Let us do all the hard parts and ship both of our great kits, fully assembled, straight to your door!

Fundraiser Notes

• Both the hardware designs and firmware source code will be completely open source and released at the end of the fundraiser.
• The pictured PrismaChron and PrismaChron PCB is a prototype version and does not represent the final look of the clock. The final PCB will be black with orange silkscreen.
• If full funding is achieved, we will do everything in our power to get all kits out to USA supporters by Christmas and international by New Years. But, sadly, we can make no guarantees.
• Orders will generally be processed in the order received, but fully assembled products may take a few days longer than the kit versions.
