Electrical engineer Gabriel Anzziani, the founder of Gabotronics who created the amazingly tiny Xprotolab oscilloscope is now working on the Oscilloscope Watch, a portable version of the Xprotolab with all its features.

Oscilloscopes are in general a waveform generator that is uses to observe the change of an electrical signal over time. It allows measurement of peak-to-peak voltage, the frequency of periodic signals, the time between pulses etc. For example a submarine usually use an oscilloscope to sense things out there in the deep sea.

The Oscilloscope Watch has all the features of a modern watch (time, calendar, alarm, etc...) combined with all the features of the popular Xprotolab (Oscilloscope, Waveform Generator, Logic Analyzer, Protocol Sniffer, Frequency Counter). You won't be able to replace your professional oscilloscope with the watch, but it is sufficient for electronics analysis for your Arduino project.

The brain of the device is a powerful 8-bit XMEGA microcontroller, easy to program in C or assembly. Gabriel has included a link to the schematics (PDF) here so users can write their own applications. As to the instrument's probes, Gabriel says a special BNC adapter will be designed that will plug in the 9 pin header to allow to use standard probes.

When using the oscilloscope, according to Gabriel, the battery will last about 12 hours. When it is not used, the analog section is turned off, so the estimated battery life will be over 30 days on each charge.

The enclosure of current prototype is 3D printed on an Afinia 3D printer. Gabriel plans to reduce its size in the future design and to make it out of plastic as the other watches.

General Specifications

• ATXMEGA256A3U 256KB Flash, 16KB SRAM, 4KB EEPROM
• Sharp Memory LCD display 1.28", 128x128 pixels
• Approximate watch size: 2" x 1.6" x 0.6"
• Li-Ion Battery 400mAh, rechargeable via the micro USB connector
• Internal PDI interface
• 4 tactile switches
• USB connectivity: PC application available, Android App available.

The watch is designed for the electronic geek - so you can be the coolest one at any gathering you attend. The designer has launched the Oscilloscope watch on Kickstarter to bring it to the masses. Pledge US$100 on Kickstarter you will get an Oscilloscope Watch and all accessories as a reward.
