Raspberry Pi GPS tracker – Connecting Without a Network

February 24, 2016 | Comment

All articles to date have been about getting the GPS working with the Raspberry Pi and converting the original Python code to PHP. All of this works well (for me) but what if you want to make changes to the settings or download the log file while you are out and about and away from your home network?

Normally what happens is that you configure your device to connect to a known network but as you are going to be using the GPS/Pi combination away from known networks you need a way to access anywhere without having to connect a … Read the rest

Raspberry Pi GPS tracker – Converting Code to PHP – Part 2

February 16, 2016 | Comment

In the last post I looked at converting the original Python code to PHP. This all ran without issue but I quickly found that because the Pi wasn’t connected to the internet the date and time of the device never got updated. This meant that the log files always had the wrong timestamp when they were created making it difficult to find the one I needed.

Turns out that there is a simple answer to this problem. As the GPS satellites include the current date and time as part of the detail that is sent along with the location we … Read the rest

Raspberry Pi GPS tracker – Converting Code to PHP – Part 1

February 9, 2016 | Comment

Last week I looked at getting the hardware up and running for a Raspberry Pi GPS tracker. However, as I said I was using some Python code and I don’t speak Python so I wanted to convert it to PHP. So this week I am going to look at what I did.

Before I could even begin to look at the converting the code I had to see if it was even possible for PHP to access the serial port. Turns out this is exactly what Direct IO (dio) is for but it isn’t included as standard so you … Read the rest

Raspberry Pi GPS tracker – Getting it Together

February 2, 2016 | 8 comments

Having secured a Pi Zero from the cover of a the magazine MagPi I thought I would start out simple by trying one of the projects shown there. The one that caught my eye and required no soldering was to build a GPS tracker.

Getting hold of a cheap USB unit was pretty easy but make sure it is Linux compatible. I bought this one from eBay.

The first thing I did when I got the unit was to try it out on the Pi and while it was working I could see that it had got a satellite … Read the rest

Microsoft Universal Folding Keyboard

January 16, 2016 | Comment

Now that screens are getting bigger on mobiles it is becoming increasingly more practical to do work on them, especially now that Microsoft Office is available on most mobile devices.

The biggest issue I have though is typing on the screen. While it is fine for short emails and text messages it isn’t really practical for longer pieces such as this blog post. One issue is that the on-screen keyboard covers too much of the screen real estate. To overcome this I’ve had portable keyboards before but they have either been clumsy or heavy to carry.

Now enter Microsoft to … Read the rest

Pebble Time Long Term Review

November 26, 2015 | Comment

So I have had my Pebble Time Steel a few months now so I thought that it would be good to revisit it and put down my thoughts having had it a while. The first thing is that I have now received my steel band and the watch looks so much better for it than the “leather” strap it was originally sent with. I’m really pleased with the look and it is a step up from the original plastic version (original Pebble) I had.

The Good and the not so Good

The watch interface has had an overhaul and there … Read the rest

Halo Back: Good idea, but does it work?

October 21, 2015 | 1 comment

A while back, although in terms of Kickstarter dates it was positively recent, a project was posted that caught my eye called Halo Back. This was a glass screen protector with a difference – the bottom left area was “mapped” to the top left making it easier to click the back link on apps. That’s poorly explained but this cheesy video from the project does a better job:

Last week the Halo Back arrived and so I stuck it on. Unlike other screen protectors the positioning is quite important and so the makers have included a frame that fits … Read the rest

New Pebble Time Thoughts

October 7, 2015 | Comment

Just thought I would put down my initial thoughts on the new Pebble Time. I’ll do a fuller review, including the same tests that I ran with the old Pebble, in a few weeks when I have captured more data.

I’ve had my steel version a couple of weeks now and it really like both the look of the watch and the new interface itself. In fact Apple seemed to like the timeline too so they pinched the idea for their watch!

When you pledged via Kickstarter the Steel variant comes with both a leather and steel link straps. … Read the rest

A little spring cleaning

July 30, 2015 | Comment

This is why you need to open up your PC occasionally and give it a bit of TLC. The pile of grubby dust above is just six months worth from our always on media server.

I got into the habit of cleaning it out regularly after it started (unsurprisingly) to become pretty noisy and given that it is in our lounge that became an issue. It is amazing the difference that a really good clean makes.

One important thing is that you MUST NOT use your normal hoover to suck out the dirt. This is a bad idea as it … Read the rest

The dio Naked Reversible USB cables

May 20, 2015 | Comment

Reversible USB cables are, it seems, a lot like buses – you don’t see any for ages and then two come along in quick succession. Just last month I wrote about the Belaycord and now here is the dio Naked from moopti.

Like Belaycord this is also being offered through a Kickstarter campaign and as of writing there are just over two days before that closes. Rather than have to wait for mine to arrive (I have backed the project) moopti kindly sent me a sample to review which arrived today.

The first thing you notice is how well the … Read the rest
