Wearable solder Time II Spikenzielabs
The Solder : Time II is the latest version of our Solder : Time watch kit. This new version is even more hackable than ever. The on board 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 has a much more impressive display. Four 5x7 LED matrix modules 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; time, date, month, words, scrolling messages, graphics, special characters ... the possibilities are endless. The ST2 also has a piezo buzzer for the alarm. You can also use it to add sounds to you custom programming or even games!
