On Monday night, Professor Brian Cox (University of Manchester)1 & Senator Malcolm Roberts (Senate of the Australian Parliament, representing the extreme right One Nation party, & climate denier)2 had a difference of opinion on climate change on the ABC (Australian Broadcasting Corporation) TV programme, Q&A.

How clean is the air you are breathing?


… & how can you know?

There is probably some sort of air quality monitoring in your town or city. In my small city, there are 3 monitors with output easily available to the public. They are 12 kilometres (7.5 miles) & 21 km (13 miles) apart. Hourly & daily graphs are available.

http://www.health.act.gov.au/public-information/public-health/act-air-quality-monitoring/real-time-graphs

Recently, there have been two crowd funded projects to provide personal air quality measurements & improve the resolution of air quality monitoring world-wide.

CleanSpace Tag

CleanSpace aims at measuring air pollution by detecting just one component, carbon monoxide (CO). Rationale is that, CO is a good indicator of pollution because:

● incomplete combustion (as in an internal combustion engine) produces many pollutants, including CO, so its presence is an indicator of other pollutants

● CO can be a significant pollutant indoors


Something that sets the CleanSpace device apart, is the use of Freevolt, which, “harvests energy from 2G, 3G, 4G & WiFi [2.4 GHz] signals”, to power the device – so no battery swapping or charging – ever.

A smartphone app (iOS & Android) connects to the CleanSpace Tag via Bluetooth & the CleanSpace website to aggregate data captured by all tags.

Even without a Tag, the app is able to display aggregated air pollution data. There is no search function in the app. Zoom & pan is required to see information for anywhere other than your own location.

At this time, CleanSpace is only available for sale in Europe, due to approval issues.

Only in London, was I able to find detectable levels of CO pollution. This is, no doubt, influenced by the limited availability, & will persist until Tags become more widely available.

If you see red lines, appearing only on roads, you are probably seeing Google indicators of heavy traffic. They can be turned off in Tag app settings.

Paul Drayson, of Drayson Technologies interviewed about the CleanSpace Tag

Atmotube

Atmotube is broadly similar to CleanSpace in that:

● a portable detector collects local pollution information for the user

● displays it on a smartphone app

● aggregates it to a website maintained by the manufacturer


Differences:

● by contrast with CleanSpace, Atmotube measures a huge array of pollutants: carbon monoxide, formaldehyde, benzine, d-limonene, a-pinene, acetaldehyde, hexanal, ethylene glycol, acetone, propane, toluene, methylene chloride, 1,3-butadiene, vinyl acetate, acetylene dichloride, xylene, VOCs in smoke, acrylyl chloride & methyl chloroform

● lithium ion battery charged via USB-C

● no aggregated data available at the time I checked

Amber – watchcase & power bank for Apple Watch

A watch that (in some hands at least) struggles to get through a day, makes charging a priority. Amber allows charging anywhere, any time.

Amber is a white plastic Apple Watch case, clad in aluminium. A Watch, inserted as in the images above, is attached to the Apple Watch magnetic charging connector. Charging is supported by the 3,800mAh battery in the Amber.

Ports at the back allow for charging the internal battery (micro USB) & external devices (USB-A).

An iPhone app allows monitoring Amber's state & Watch charging.

Surprisingly, Amber was funded on both Kickstarter & Indiegogo.

Tesla Autopilot 2.0



Credit: Twitter/@jeremywaite

Tesla is about to release a substantial update to the Autopilot hardware & software. New hardware is expected to include radar at each corner, in addition to the existing front-facing radar. The front-facing camera is expected to be upgraded to a triple-system with 25, 50 & 150° fields of view.

LIDAR is not expected to figure in Autopilot 2.0. Tesla is thought to prefer radar for its ability to see through rain, snow, fog & dust.

Software for the 2.0 system will be released as incremental, over-the-air updates, as in the past.

QuadRooter – relax, the world’s not about to end



Credit: Top 10 SM

As indicated in these pages yesterday, the QuadRooter vulnerabilities are real, & they do pose a potential risk to your Android device.

However, there are multiple layers of protection, available since Android 4.2, that should keep your device safe:

● QuadRooter needs to be installed as an app

● Unknown Sources setting – by default, Android devices only allow installation of apps from the Google Play StoreGoogle’s curation is not infallible, but represents a substantial defence against malware in apps

● Verify AppsGoogle has confirmed that Verify Apps can identify & block apps using QuadRooter – if a user attempted to install an app with a QuadRooter payload an, “Installation has been blocked”, message would appear, with no option to ignore & install
