Description: The Solder : Time II is the latest version of Spikenzie Labs' Solder:Time watch kit. This new version is even more hackable than ever. The onboard microcontroller in this model is the very popular ATmega328P used in many of the current versions of Arduino. In fact, you can reprogram your watch using the same Arduino IDE software that you use for a regular Arduino!
The Solder:Time II is different from the original Solder:Time in many ways. The display has been upgraded to a set of four 5x7 LED matrix modules. This gives you control of a 7x20 matrix for a total of 140 LEDs! The new LED matrix allows for an amazing amount of information to be displayed; aside from the current time... The date, month, words, scrolling messages, graphics, special characters ... the possibilities are endless. It also comes with a piezo buzzer for the alarm function, but you can use it to add sounds to your custom programming and games.
Much like the original Solder:Time, the Solder:Time II comes to you as a PTH kit. There are SMD parts already soldered to the board when you get it, so don't worry about trying to solder those tiny lead-spacings. The body of the watch is still a "stacked acrylic" construction, but some changes have been made to make the watch sturdier and easier to assemble.
