Thursday, 08 September 2011 08:53

Communicate anywhere, any time … without infrastructure, without mobile towers, without satellites, without wifi hotspots, and without carriers. Use existing off-the-shelf mobile cell phone handsets. Use your existing mobile phone number wherever you go, and never pay roaming charges again.

Broadband's frequency hunters denied Freeview patch – for now
Friday, 27 November 2015 00:31

Freeview is safe. For now. Mobile operators with broadband services were denied the 470-694MHz frequency used by the terrestrial TV service.

The decision was taken at a World Radio Conference (WRC) in Geneva, Switzerland with a review of the whole UHF band planned 2023. Essentially, the future of Freeview is now assured, probably at least until around 2030. Things move quite slowly in the world of frequency allocations: the ramifications of the last WRC, held in 2012, are still rumbling on.

It was at that meeting that the decision was taken to clear the 700MHz band for mobile services. The

ESP8266 BASIC WiFi Thermostat is Child’s Play
Sunday, 29 November 2015 06:01

If you’ve read any of our posts in the last couple years, you’ll have noted that our community is stoked about bringing the Internet to their devices on the cheap with the ESP8266 modules. Why? This forum post that details making a WiFi thermostat really brings the point home: it’s so easy and cheap to build Internet-enabled devices that you almost can’t resist.

When the ESP8266 first came out, there very little documentation, much less code support. Since then Espressif’s SDK has improved, the NodeMCU project brought Lua support, and there’s even Arduino support. Most recently, BASIC has been added …read more

Power Over WiFi Might Not Be A Unicorn After All
Saturday, 28 November 2015 12:01

There have been a few reports of power over WiFi (PoWiFi) on the intertubes lately. If this is a real thing it’s definitely going to blow all of the IoT fanboys skirts up (sorry to the rest of you *buzzword* fanboys, the IoT kids flash-mobbed the scene and they mean business).

All of the recent information we found points to an article by [Popular Science] titled “Best of What’s New 2015”. The brief write up includes a short summary lacking technical info, and fair play to [PopSci] as it’s a “Best Of” list for which they hadn’t advertised as an …read more

Absurd Clock uses Twelve ESP8266 Modules
Friday, 27 November 2015 18:01

Quick quiz: How many ESP8266 modules do you need to make an LED clock? Hint: a clock displays 12 hours.

Nope! Twelve is not the answer. But that didn’t stop Hackaday.io user [tamberg] from building a 12-ESP clock during the Bilbao, Spain Maker Faire. The “advantage” of using so many ESP8266s is that each one can independently control one hour LED and its associated slice of five minute-marker LEDs. Each ESP fetches the time over the Internet, but only lights up when it’s time.

It’s like parallel processing or something. Or maybe it’s redundant and failsafe. Or maybe it’s just …read more
