Spark Core: Wi-Fi for Everything (Arduino Compatible)
- digitalWestie 14y agoglad to see more arduino compatible wifi alternatives getting out there
- stephengillie 14y agoOh cool, someone else has made the project on which I was working... Edit: they made it way cooler than I ever dreamed of making mine.
- decktech 14y agoI'm holding out for WiMAX.
- tocomment 14y agoWhat's new about this? Just that you don't have to buy an arduino and wifi separately?
- csmatt 14y agoIt also looks like it will be well-integrated and I think that's where the real value is.
- stephengillie 14y agoThere's an incredible amount of value in "well-integrated". I wasted weeks trying to get an Arduino to have enough control over an Xbee to get it to even see wifi networks. And Xbees were designed to work over existing wifi frequencies...
- unwind 14y agoThis is much smaller than most Arduinos (certainly smaller than the official Arduinos). Processor-wise I guess it should be comparable to the Arduino Due (http://arduino.cc/en/Main/ArduinoBoardDue http://arduino.cc/en/Main/ArduinoBoardDue) which has an 84 MHz Cortex-M3 (the Spark Core runs at 72 MHz). The Core seems to have more code space, with a 2 MB external flash.
- dyselon 14y agoUploading sketches via wifi is a unique feature, isn't it?
- mik3y 14y agoIt's understated on the kickstarter, but it looks like this is a vehicle for a new cloud development environment: You can program your new software in our web development environment or in your favorite text editor, and with a single click, Spark Flash delivers updated firmware to your project over the web.
- stephengillie 14y agoHopefully it'll mark the shift away from USB and PCs as the main development connection and platform, and towards wifi and tablets. Yes, reprogram your coffee maker while your car drives you to work.
- marssaxman 14y agoI hope that you are joking, but I can't tell these days.
- graeham 14y agoPretty awesome! Arduino + BT4.0 next, please! This could (or would have in my case) been very handy for prototyping wearables. BT4.0 is better for battery usage and phone connectivity in production-ready wearables though.
- postscapes1 14y agoRFDuino also just got funded: http://www.rfduino.com/ http://www.rfduino.com/
- StavrosK 14y agoThat's brilliant. Is there any way to get a wifi module like this on the Raspberry Pi? All the ones I've found require external power (i.e. a USB hub)...
- codysoyland 14y agoThere are compatible USB wifi modules, like this one: http://www.adafruit.com/products/814 http://www.adafruit.com/products/814
- StavrosK 14y agoHmm, that one says it might need a hub too. I have a similar one, if not that one, and the Pi was freezy without a hub, when using the adapter.
- ja27 14y agoI've used both of these without a hub without any problem. I use an old Samsung cell charger (I think 700ma). I don't generally have anything else drawing power from the USB port though. http://www.amazon.com/gp/product/B0037G2BMY/ http://www.amazon.com/gp/product/B0037G2BMY/ http://www.amazon.com/gp/product/B004LPY204/ http://www.amazon.com/gp/product/B004LPY204/
- mmastrac 14y agoI recommend this one: http://www.monoprice.com/products/product.asp?c_id=105&cp_id=10501&cs_id=1050108&p_id=8072&seq=1&format=2 http://www.monoprice.com/products/product.asp?c_id=105&c... It worked with zero extra setup on my Pi. Plugged directly into Pi - no hub.
- StavrosK 14y agoI'll give it a shot, thanks! It's possible that my USB adapter doesn't supply enough power, though, so I'll try a bigger one first.
- bichiliad 14y agoThis is very similar to the ElectricImp project: http://www.electricimp.com http://www.electricimp.com
