AVR Oscilloscope Clock : O-Clock

The O-Clock can convert your X-Y analog oscilloscope into an analog clock or terminal. In addition, it can be used alone as a function generator. It is very similar to the AVR Oscilloscope Clock Kit, but this board is all SMD and comes fully assembled.

The O-Clock is based around an ATmega328 which is interfaced with a DS1307 RTC module and an AD7302 DAC. A cell battery backup is provided so the clock won't lose its time. The oscilloscope can be connected to the O-Clock through BNC connectors (not included) or by probing the CH1/2 turrets.

SPI Shortcut

The SPI Shortcut allows you to control SPI pins over USB, allowing for a virtual "SPI Terminal." Using basic serial commands you can access any SPI device such as sensors, media, and even program some devices. You can change all of the SPI features (frequency, data order, etc.) on the fly with no programming involved! Comes with a simple-to-use terminal interface. All you need is the FTDI USB driver and a basic terminal program.
