The basic Bulbdial clock kit ($65) comes complete with three custom circuit boards, 72 ultrabright LEDs, pre-programmed ATmega168 microcontroller with Arduino bootloader, tactile button switches, aluminum standoffs, 20 ppm quartz crystal, custom clock face, gnomon spike, universal-input plug-in power supply, stainless mounting hardware, plus the resistors, capacitors and other little parts needed to build the Bulbdial clock.
LED Style
The kit comes with 12 red, 30 green, and 30 blue LEDs, marking hours, minutes, and seconds. The colors provide contrast and tend to mix in interesting ways. This is the standard 3-color option.
Case Style
The Bulbdial clock is designed to be mounted in a handsome, laser-cut acrylic case ($20) that makes it suitable for desk or mantle use. Cases come in Tortoiseshell, or Abalone Pearl. Please specify your choice.
Rear-projection clock face
The Bulbdial Clock Kit is designed to be used with either an opaque clock face in the back, included with every kit, or with a translucent clock face for rear projection. The rear projection clock face is made of translucent textured diffusing acrylic. It is laser-cut to shape and screen printed on one side.
USB-TTL Cable
The FTDI USB-TTL converter cable (model TTL-232R-5V) provides an optional interface between your computer and your Bulbdial clock. It can be used (1) to sync the Bulbdial's time to the time on your PC, (2) to reprogram the Bulbdial clock through the Arduino IDE, or (3) to make the Bulbdial clock into a USB powered Bulbdial clock.
ChronoDot
The Bulbdial clock kit has a socket on the circuit board to accept an optional Chronodot module as an upgrade. It provides your Bulbdial kit with (1) a higher accuracy quartz crystal oscillator, (2) a backup battery, and (3) extra geek cred for having a TCXO-based RTC. The included battery is estimated to last for 7 years.
Building it
The Bulbdial Clock is sold as a soldering kit [?]. Basic electronic soldering skill is required, and you provide basic soldering tools: a soldering iron + solder and small wire clippers. You will also need internet access to read or download our detailed assembly guide. No additional knowledge of electronics is presumed or required. Easy "through-hole" construction and clear, photo-heavy instructions are provided. Assembly time: 1-3 hours, depending on your level of experience with soldering.
Open-source
The Bulbdial clock kit is open-source in both hardware and software, and is designed to be user friendly and hacker friendly. The on-board microcontroller is an ATmega168, running a program atop the Arduino bootloader. FTDI USB-TTL and AVR-ISP programming header locations are provided on the circuit board. The circuit board also features alternate mounting hole locations-- in case you're building a different case, and a location for a 5 V regulator. An extended introduction to the project and its design is available here. The schematic diagrams and source code are posted and available for download on that page.
Power supply
The Bulbdial clock kit includes a universal-input power supply that will work with worldwide voltages. The plug is a power-strip-friendly US type, so you may need an inexpensive "grocery store" plug adapter to fit the wall socket in your country.
