Adding ePaper navigation data to a sailboat

[Mike Holden] has been on the hunt for a display that is easy to read in bright sunlight. He wants to use it to read out navigational data on his sail boat. The best option is an ePaper display. He managed to build a system that will feed updating NMEA 0183 data to a Nook Simple Touch.

NMEA 0183 is a protocol that governs data from marine navigational equipment. The most obvious is GPS, but there are a lot of possibilities like sonar, a gyrocompass, and an autopilot. To get things rolling he wrote an Arduino sketch which generates dummy packets using the standard. This let him develop and test the system without being near any of the real equipment. The heart of the build is a WiFi router. It pulls in the data over a USB port using an RS232 to USB converter cable. A Python script parses the data and generates a webpage which refreshes the data every second. This is loaded using Opera browser on the Nook

Check out the video after the break to see a demo of the system.

PlayStation gaming on a NOOK Simple Touch

Improvements in processing power really hit home when you see an eBook reader playing PlayStation games. Sure, we’re talking about a system which launched more than 15 years ago (the original PlayStation launched way back in 1995), but this is a $99 device which seems to be playing the games at full speed!

[Sean] wrote in to share the project with us. After rooting the device he installed System 7 (aka Mac OS 7) using Mini vMac for Android. He uses Free PlayStation Emulator (FPSE) to run the games. There is an Android version which provides the touch-screen controls you see above. We figured the graphics would be awful, but the video after the break proves us wrong. Other than being in black and white we think the graphics are fantastic. Just one hack was necessary to make this happen. [Sean] uses NoRefresh to keep the Nook from refreshing the screen which is what causes the film-negative type of flashing after several page turns.
