World Maker Faire! Kinda. I stuck to the Raspberry Pi Q&A with Eben Upton, one of the Raspberry Pi creators (https://www.youtube.com/watch?v=Gg-YXqM2xs4&feature=plcp)
Why did I choose Raspberry Pi? I’m very fond of this device. It’s a mobile computer that isn’t a smart phone and has USB, Ethernet, an SD card, and HDMI/composite out. If I could establish a line of communication between it and my little project, it would save me the trouble of worrying about shields and programming for the Arduino (proof of concept in accelerometer data gathering found in a video in a link of one of Entry 2). Raspberry Pi provides a rather complete computing environment, and has USB which can power the Arduino. Plug in a hub and you can power 8 without an external power supply! It’s great.
On to the Q&A, what did I learn? Kinda disappointingly little. Partly because what they were talking about at the beginning was too in depth for me to understand (like the electronics of a processor) and partly because they relayed a bunch of information that I was already aware of (Raspberry Pi’s great, you get a mobile computer that has Linux on it so you’ve got all of the programming tools and peripherals you know and don’t need to learn anything new to make it work the way you want). However, I did learn that it has some form of I/O capabilities. This is very intriguing, as it opens up the possibility of non USB communication, which may reduce the bandwidth load on the Arduino. I do not however, know how many pins or how much bandwidth we’re talking. Investigation awaits!
The Raspberry Pi sounds rather intriguing. I ‘m curious though, how does it differ to the Arduino, i take it it’s more powerful and has it’s own OS, but can it replace an Arduino or can they work together as one (without biting each others heads off).
I looked this up a bit and it sounds like a pseudo computer. Did I get that right?
I’m all for a mobile computer that’s not a smart phone and Ethernet just makes it better as an option though not really a mobile option. Was there a focus for Raspberry Pi to have non usb communication? otherwise I think the multiple types of i/o ports would just be extra. Although it might be aiming towards that as a complete computing environment but that’s what I’m asking.
