Step 6Taking it further, get your own
We designed the #twatch to make full use of the resources on a single chip, an expanded design would add features but be more expensive.
The #twatch could follow your own Twitter feed. It would need a small web server to enter your Twitter login, and an external EEPROM to store the configuration information.
The #twatch could also store more tweets or extra information about each tweeter, such as name and location. Microchip doesn't make an integrated ethernet controller with more than 4K of RAM, but we could add an external SRAM to store tweets and tweet meta-info.
Updated hardware could add an I/O header for connecting buttons with LCD Smartie.
A 20character by 4line LCD doesn't have a lot of display space. We designed the #twatch interface around this limited amount of space. An updated firmware could handle multiple screen sizes.
The bootloader can adopt the IP address acquired by DHCP. A future #twatch firmware update will take advantage of this feature for easier network upgrades.
Next week we'll cover the LCD Smartie compatible TCP server built into the #twatch.

What's twending on your #twatch? If you want an assembled #twatch or PCB, here's a couple options:

What's twending on your #twatch? If you want an assembled #twatch or PCB, here's a couple options:
- Seeed Studio has a few assembled #twatch ethernet LCD packpacks for $45, including worldwide shipping. Get them while they last because we won't make more soon. If you missed this project, sign up here to be notified of future #twatch preorders.
- If you want to build your own, Seeed Studio is selling the extra #twatch v1 and v2 PCBs from our order. Be sure to get an ethernet jack from Seeed, or make sure you can find one that matches the PCB. We'll write about v1 in a few days, the schematic and PCB are in the project SVN.
- We'll send a free #twatch v2 bare PCB to the first 2 people who tweet the #twatch.
Next week we'll show you how to redirect LCD Smartie system stats to the #twatch TCP server.

Would it be possible to configure the unit to display RSS feed data from LCD Smartie instead of system stats?
