iPhone vs Android

A friend who’s a long-time iPhone user just asked for my advice about whether to get a Samsung Galaxy S3, a Samsung Galaxy Note 2, or a iPhone 5.

Advantages for Android

I think that liberty should be the first consideration, I’ve previously written about how Android phones won’t necessarily give you as much freedom […]

Power Supplies and Wires

For some time I’ve been wondering how the wire size for power supplies limits the power. So I’ve done some quick calculations to determine if it’s a problem.

The first type that is of interest are the “Inverters” that are used to convert 12VDC to 240VAC (mains power) to allow electric devices to be operated […]

Cooling Phones

According to the bureau of meteorology today is 39C. But mad dogs and Ingressmen go out in the midday sun, so I took advantage of some spare time to capture a couple of portals.

After that my phone battery was apparently at 46C and my phone refused to charge.

It seems that in addition to […]

Android Multitasking

My new Samsung Galaxy S3 has support for “Multi Window Mode”, here is a video which shows how to use this, Multi Window Mode starts at about 2:30 [1].

A common complaint about Android is the lack of multitasking, which is partly true and only slightly alleviated by Multi Window Mode.

Running Multiple Programs

Traditionally […]

Samsung Galaxy Camera – a Quick Review

I recently had a chance to briefly play with the new Samsung Galaxy Camera [1]. The Galaxy Camera is an Android device with a 4.8″ display (the same size as the Samsung Galaxy S3) that has a fairly capable camera (IE nothing like a typical phone camera). It runs Android 4.1 (Jelly Bean) and the […]

SIM Annoyances

My new Samsung Galaxy S3 phone takes a micro-SIM (see the Wikipedia page about Subscriber Identity Modules for details [1]). All my other mobile devices take a mini-SIM so I can’t just put the SIM from my old phone in my new phone. I’ve just made my second application to Virgin Mobile for a new […]

Samsung Galaxy S3 First Review with Power Case

My new Samsung Galaxy S3 arrived a couple of days ago. Kogan added to the weirdness in their shipping that I documented in a previous post [1] by shipping the two phones on consecutive days with separate invoices for $789 each (as opposed to the $449 that I paid). This means that if customs were […]

Dependencies in Online Ordering

I have just ordered two Samsung Galaxy S3 phones and matching cases from Kogan. The price was good and Kogan gave me 30 cents discount as part of a verification process. Instead of billing the full amount for a large order (for which the cutoff is somewhere between $25 and $1014) Kogan will deduct a […]

Returning the Aldi Tablet

I have decided to return the 7″ Android tablet I bought from Aldi last week [1]. I still think that the tablet isn’t all bad, but the main problem I had is the short battery life. The battery can be entirely exhausted in less than an hour’s use. Another problem is the fact that most […]


Today Google sent me an invite for Ingress – their latest augmented reality game [1]. The fact that they sent me the invitation while the Google Play store page for Ingress [2] tells me that it’s not available in my country (Australia) is interesting. Google obviously aren’t using their Big Brother powers effectively!

The way […]
