Internet Knows Your Every Move Thanks to IKEA and ESP8266
Monday, 30 March 2015 23:01

[terenceang] got his feet wet with the ESP8266 WiFi module by hacking up an IKEA Molgan PIR light. The stock PIR light simply lights when motion is detected. [terenceang] added some extra functionality to it by making it send notifications to his phone as well.

The default configuration of the stock PIR light was to only work at night. This is done with a photo diode. It was removed to make it work in daylight, along with several other components. He removed a handful of current limiting resistors to disable the hi output LEDs. One was preserved as a visual …read more

WiFi Sucks for RC Vehicles, Upgrade to 3G
Tuesday, 31 March 2015 02:01

This is the Kyosho Blizzard, a tracked remote control vehicle that’s a blast to take out in the rapidly retreating snowpack. [Antibore] was interested in performance testing the range of the thing. It includes a camera that streams video back to a tablet or smartphone. Both the video and the controls use WiFi for communications.

Not a bad idea that may be feasibly completed with hardware you have …read more

Speaking to US conference, professor Tucker said the claim in the latest strategic review that FTTP rollout ran at $AU4,300 per household had led to confusion over costs.

As already noted by Vulture South, the latest corporate plan from NBN Co, the organisation building the NBN, refactored the basis for the per-premises rollout calculation – for example adding operational expenditure to the capital

BT slams ‘ludicrous’ Openreach report as Vodafone smirks
Thursday, 26 March 2015 20:47

BT has labelled a report into its apparently inflated return on broadband investment as "ludicrous", as Vodafone calls on the government to tighten the regulations surrounding Openreach.

A confidential November 2014 report from Frontier Economics (seen by El Reg ) has claimed that while the historic return on investment, which Ofcom uses as a benchmark for BT Openreach, is between 8-11 per cent, the actual figures over the last eight years have been much higher, peaking at more than 18 per cent.

However, BT has lashed back, claiming that this "report is ludicrous and it was ludicrous two years ago
