Designing Hardware for the Internet of Things

Awesome - keep up the great work!<p>I'm working on one of the next upstream problems in the IoT space: once you have a way to connect a device this to a network, how do you tie it into the greater set of things, program it, make it discoverable, and manage it.<p>My stab at this is called Magenta, which is an MIT licensed project based on node.js that aims to make it easy to build devices that can securely communicate in real time and applications that interact with those devices over a message passing model (its hard to explain in one paragraph but think of it like this: twitter for devices with agents watching those messages).<p>I'm only a month into it and a few hundred commits, but if you are interested, check out the (very early) project at <a href="https://github.com/magentajs" rel="nofollow">https://github.com/magentajs</a> or contact me on twitter at @timpark. I would love to get some feedback or find folks interested in helping collaborate on one of the subprojects (client sdk, service, administration tool, or use it to build devices and provide feedback and bugs).<p>Ok, I'm done hijacking your thread!

Another interesting internet of things module: " The RS9113 M2MCombo supports dual-band 802.11n and dual-mode BT 4.0 in addition to Zigbee. Redpine (San Jose, Calif.) will ship the device before June in a variety of module form factors at a cost of $6 in 100,000-unit quantities."[1]<p>Hopefully it will also get into a shield form factor, at a reasonable price, since it seems ideal to trying all kinds of things out.<p>[1]<a href="http://www.eetimes.com/electronics-news/4406270/Redpine-device-packs-Bluetooth--Wi-Fi--Zigbee-" rel="nofollow">http://www.eetimes.com/electronics-news/4406270/Redpine-devi...</a>

The CC3000 is IPv4 only - what the f<i></i>k?! I understand it greatly increases cost in manufacturing, but isn't one of the key sale points of IPv6 that the IPv4 address space is going to run out in part because of the Internet of Things!?

FWIW, that image is a preview from the OSH Park ordering site[1]. I can highly recommend the service for prototype 2- and 4-layer boards. The price is right, the turnaround time and customer service are awesome, and the specs are better than anything else I've found in the price range. And they're purple.<p>[1] <a href="http://www.oshpark.com" rel="nofollow">http://www.oshpark.com</a>

I'll point out that it is very clear that there will be BLE support in stock android(Samsung supports BLE via a device specific SDK) after the Google IO release of the Android.<p>Google's Glass supports BLE based on the FCC approval documents. It appears that BLE support was prioritized after the Bluetooth stack rewrite that happened in 4.2.<p>The Galaxy Nexus, Nexus 4, Nexus 7 and Nexus 10 all have hardware capable of BLE that should be available after the update.

Great work. I've been keeping a close eye on the CC3000 for some time. I've also looked at the Wi2Wi modules/chips. I've been working (whenever work and home allows) on some hardware to connect the CC3000 with a Xilinx FPGA. Hopefull, I will have some results soon.<p>Also, I really like seeing hardware on the front page.

I've played around with a WiFly module sold by sparkfun that seems pretty functional and reasonably cheap at 35$.<p><a href="https://www.sparkfun.com/products/10822" rel="nofollow">https://www.sparkfun.com/products/10822</a><p>Any idea how much cheaper this could be?<p>By the way your site doesn't seem to have a valid RSS or Atom feed. Your html has an incorrect feed link back to the homepage itself:<p><pre><code> &#60;link href="./" type="application/atom+xml" rel="alternate" title="Eric Evenchick ATOM Feed" /&#62;</code></pre>

This looks like a nice shield for that cc3300. Nice to see more hw-related stuff on HN - thanks for sharing.

Cool project.<p>If your interested in some feedback on the PCB layout I'd be happy to help (e-mail in profile). There are a few things about the pictured layout that will make it very prone to noise and EM radiation as well as some heat dissipation issues.
