I've enhanced my Motion-OLED Moteino project and added a few more features to the already existing ones:

• a general purpose button which is wired to interrupt 1 (pin D3) of the Moteino. This is useful to wake it up from sleep and respond to whatever command you have it do. For instance, I've programmed it to browse through past received messages from the wireless network, or it can be used to access a user menu where you can choose different modes of operation.
• The OLED can display anything you want. I like to keep the OLED mote in the kitchen area where it provides a hands-free alternative method to check the "snail mail". The periodic messages received from across the street (thanks to the powerful and very small RFM69 transceiver) are displayed on the OLED with the last time the mailbox was opened, very convenient.
• The ON-OFF slide switch can cut power from the LiPo battery, which in my case is a 1300mAh which lasts about 3 days with the OLED kept ON and the transceiver in RX mode all the time to listen for messages.
• The USB port allows easy programming from the Arduino IDE and also charges the battery in about 2.5 hours when fully discharged.
• A buzzer allows you to hear when a messages is received, or to alert you when mail is delivered, a garage door opens, a light turns on, etc.
• And of course, the same PCB/kit can be used as a low power motion detector by inserting a PIR sensor instead of the OLED display, quite versatile.
• I've discovered thinner acrylic makes for very nice cases that are easier to assemble and I might switch from thicker 3mm acrylic for such enclosures. Acrylic is found in many colors and shades which means these enclosures can be of many colors. Just look at a variety here.
• this kit will replace the current MotionMote kit and will also be usable as a mailbox notifier and standalone receiver for those who just need a motion or mailbox sensor and are not interested in the whole automation framework.

As of today I am still waiting for production PCBs to be delivered and tested, and once everything is confirmed ready to go I will post the details and sample source code for the OLED display shield. For now here's a sneak peek of what's coming:
