As we desire to seamlessly embed the electronics within our eTextiles projects, we often seek for small but powerful computation or small and energy efficient solutions. Lilypad to Teensey, there are many choices, but what do you choose? and why?
When the project needs to connect with other computers and networks, the problem is even bigger. How do you connect wirelessly? Bluetooth? Xbee? WIFI?
Let’s Geek out and experiment with small solutions, battery and wireless modules.
let’s build a sensor-actor network and figure out what to do with it.
WIFI module for eTextiles:
connect eTextiles with a network. what for and why? IoT(extile) geek-out.
how do you power your projects when it is small and wireless? Lipo battery? coin cell? 9V? or any other? what are the pro and cons of these battery choices? Is there an ultimate choice?
(Bluetooth and RF12 board, double wireless (bluetooth for Mindwave connection, RF for communication between Exaltation silhouet and other morphing silhouet; double batteries required: lipo for microcontroller and added will be a powerpack for the servo’s. If you put the servo’s and the microcontroller on the same batteries you have a problem if the servo’s are switched on.
