So here’s the scenario. You’re the boss and everyone needs to
kiss up to you speak with you about important project details. You need a receptionist, or a creative employee who will build a calendar display the lets people check if you’re free to chat. It works by querying a Microsoft Exchange server for the guy’s calendar. The hardware within doesn’t deal directly with the full Exchange API, but relies on a server-side script that feeds it info on request. This is a nice touch since you can do a lot of filtering on the server and keep it simple with the embedded electronics
Speaking of embedded hardware, this uses Gadgeteer modules. You probably don’t remember, but these are Microsoft’s electronic modules aimed at C# and .NET programmers. It uses the main board, and LCD, USB host, and Wifi modules. This is the first project we remember seeing since the hardware was announced.
We wonder if this will change the boss’ behavior? Will he start scheduling creatively so that he gets more time without interruption?
[Bob Alexander] wrote in to share a hobby of his that we thought was pretty timely considering the new year is quickly approaching. For several years now he has put together a custom calendar for himself, including both dates he finds important along with sweet pictures of vintage computer equipment. Friends and family found his calendars so intriguing that they asked him to make some for them as well.
Each year his stack of calendar requests grew, and he found that no outlet – online or otherwise could produce exactly what he wanted. Instead of settling, he wrote a small application that lets him customize and print calendars to his heart’s content.
We think this is much cooler than buying one at your local bookstore, and we’re guessing that our readers likely agree. If you were creating your own custom calendar, what cool vintage computer hardware would you choose to display? What if you were designing a Hack-a-Day calendar? Let us know in the comments – we’re itching to find something interesting to look at while we count down to New Year’s Eve!
The PCF8563 is a real-time clock/calendar/alarm chip with an I2C interface. This would be useful in projects where the primary microcontroller doesn’t have enough resources for an interrupt driven clock.
We demonstrate the PCF8563 using the Bus Pirate after the break. For a limited time you can get your own Bus Pirate, fully assembled and shipped worldwide, for only $30.

[Aaron] a google employee came up with an idea that would be good for the environment, as well as fun. The Radish is a solar powered display, updated from a google calendar, with extremely low power consumption. They are building this to be an indicator of the conference room schedule. When we first read this, we wondered just how much greener it could possibly be than printing a few sheets of paper. Then we read that they were going through six reams per day. wow. The Radish gets its power through a solar panel, and preserves it through some creative power saving modes and the fact that it has an LCD that only requires power to update. Would this be a good place for some E paper? Data is transferred using IEEE 802.15.4, which is slow, but also more efficient in terms of power than normal WiFi. The system is so efficient, it can run for 3-4 days in low light conditions after a charge . Another cool fact is that [Aaron] got to design and build this on company time. Google allows people to spend 20% of their time on innovative new projects of their choice.
correction: the LCD goes into an extremely low power “sleep mode” when not being updated, and retains the last image loaded.
