What is it?

Kit for a ProMini shield clock with I2C 128x64 OLED display and RTC (DS1307).

Why did you make it?

Build a small OLED clock based on the ProMini board. I haven't seen any other ProMini OLED clock shield yet.

What makes it special?

small form factor;
programmable, hackable, open source;
show time as you fancy: analog (round clock face), digital (HH:MM:SS), Pong etc;
geeky desktop gadget;
can be powered from rechargeable LiPo battery;
QR-code sketch (photo #4) courtesy of MikeM.

There seems to be more than one kind of ProMini. This shield requires the kind that has pins A4 and A5 positioned as shown in the last photo.

This kit includes the 0.96" OLED display.

The OLED shown in the video is 2.42" and can be bought on ebay for about $20.

You have the option to include the ProMini programmed with the clock sketch, for an extra $7.

Nice little clock

Nice clock kit although it could use a little documentation. However, designer provides excellent support. I had a bad clock chip which he assisted troubleshooting and provide a replacement. It requires externally supplied 5 volts to support the clock chip which makes battery operation unpractical. However, it is easy to build and a neat, small clock. I may try replacing the clock chip with a lower power version and add a battery for a standalone clock. Thats the fun of open source hardware and software. All in all I am satisfied and with the support the designer provides makes this a project worth purchasing.
