About a year ago a microscope came to be in my possession [legally] I might add. It needed a little work to make the light focusing platform to work properly but that was completed in July.

I also ordered some prepared slides with your standard introduction to looking at little things samples. It was pretty good looking through the microscope at these. What I want to do soon is get some blank slides and then cut stuff open to get my own samples for viewing. Here’s a photograph, taken through the view piece by placing the camera lens on top of the eye piece. I think it’s a photograph of a housefly leg.

I’m looking forward to seeing more of less of the world.
This is an update on the ADS-B device. I have written about this in the previous two communications, here and here. So, on Tuesday 2nd August the Raspberry Pi arrived. Since then I have been setting it all up so the receiver is no longer dependent on the PC being on.
The first thing was to install the correct OS on the Pi. The picture shows it in initial phase with monitor, ethernet, keyboard and mouse all connected. Once the OS was installed I had to tell it to not load the GUI and just run a command line. Then, I got it connected to the network and pretty much removed all the cables apart from power.
I can connect to the Pi using SSH and run script from the command line. Next phase was to load the USB stick drivers and software. This was reasonable. Next up was the ADS-B reading software, installing and getting it running seemed easy enough and then I had to adjust some code to make sure this service starts up from boot. Next software to load was the MLAT server program, this was easy enough although initially I couldn’t quite find the correct code to check it was running.
Then, the whole set up was tested in the dining room window.
Today has been the task of moving the unit to the loft. I didn’t have any power sockets up there so one had to be installed and that took the time! Once that was done the system just needed to be secured onto the main beam in the loft. The important thing is to keep the length of the cable from aerial to dongle as short as possible, this increases the signal going into the Pi. The loft set up has been tested and it is running fine.
I have access to the Pi either via the PC using a program called PuTTY or the iPhone using an SSH connection. I can shut down the Pi remotely and monitor the internal temperature of the device. It is running at a range of 50-60 Celsius. Using a Pi to run this software is a bit like taking a sledgehammer to a walnut. But, it is independent and runs remotely. I am happy this procedure was reasonably straight forward!
The next stage is to get a more specialist aerial and maybe a more specific USB Dongle. However, this is one of those things where the amount of money you spend can be unlimited. You know, I could just install a radar up in the loft. However, here is the current splat for the range of the aircraft from my ADS-B receiver.
Loft Splat
Now that I’ve been reading a bit more about this type of thing I can explain a little more. ADS-B is broadcast by many aircraft and they send this on 1090MHz. These are the signals I receive in the loft and can see on my Virtual Radar Server software. I also send these signals over the internet to a new “radar” website. The ADS-B signals contain bits of information about position and heading, these are sent to a server which can determine positions of other aircraft by using time differences between signals arriving, this is called MultiLateration or MLAT. My Pi is part of this network allowing Radar360 to “see” more aircraft than just ADS-B alone.
I’m interested in aircraft. I don’t know why it started but it’s pretty much always been there. I grew up near Stansted airport and I can remember seeing the Space Shuttle visit in the early 80s, I saw the 747 and Shuttle circle around from the primary school playing field. When I studied art at secondary school every picture of mine contained an aircraft much to my teacher’s annoyance.
Nowadays it’s easy to see aircraft on the web. I have the planefinder app installed on my phone and often tweet when I spot an A380. I only really tweet the A380 as it’s massive and extremely beautiful.
My aircraft thing also meant I travelled to Stansted to see Air Force One take off a few months ago.
28000
I wanted to find a way to see what military aircraft are doing in the skies and I found a website called 360Radar who have this information. The site isn’t open to public yet and I emailed to see if I could get a test account. They said yes.
I like the site. I like the filters and information that I can see. This site relies on people sharing their MLAT data with them and they will offer a free account if you share data. They have a great comprehensive guide to setting up a system that is currently here. I ordered a small aerial and it arrived today. Within about thirty minutes of getting to the computer I was running the data server and sending information to the network.
I have a USB aerial picking up 1090MHz signals from aircraft. I then have a small program running to collate that data and form it into useful data.
Screen Grab of ADS-B Signals
You can see that I am picking up an aircraft over Cherbourg which I think is quite impressive. All of my aircraft are south of my position because my aerial is placed in a south window. I will look into moving the aerial to a more central, higher position in the house so that I can pick up aircraft all over!
Here’s another screen grab of the output from my aerial.
Another ADS-B Map
How it works
Many aircraft broadcast position information on 1090 MHz. This information comes from the aircraft’s navigation system but does not require the pilot to be involved in the operation of the system. The position of the aircraft is determined by GPS. This output information is called Automatic Dependent Surveillance Broadcast. My little aerial picks this up and reads it. My computer then sends this information to a website which aggregates the information.
For aircraft that don’t output the ADS-B signal their position and direction can be known using multilateration [MLAT]. This involves two or more base stations and measuring the time difference between each station receiving a signal. It’s very clever!
Tool a trip to see Ratchet and Clank [The Movie] at Rochester Cineworld. I’m feeling somewhat let down by this film. Anyway, before looking at a Parish Rating you should read this communication about my rating system. As is custom I have also shared my rating using twitter.
The game is brilliant. It’s just about my level of intelligence and playability. I really liked “A Crack In Time” or whatever it was called and I thoroughly enjoy and love the latest game.
The game is based on the film which is based on the game. The problem is that the game is much much better than the film. I wouldn’t recommend any one to see the film. Such a shame really it could have been brilliant.
This afternoon I went to Brands Hatch to see some Club Car Championship races. It was very agreeable and a good way to spend the afternoon. I had forgotten the smell and sounds of the place!
As usual I took the camera to this place and got a few shots. There are a number of communications within this site with pictures of cars, but if that’s what you like then so what!
A Supermarine Spitfire flew over twice, once on the way to a show and once on the way back. It was lovely to see even though I couldn’t hear it!
This is the sound of Lotus cars, mostly Exige, racing down the Brabham Straight.
Here is a picture of my Indiana Jones Minecraft character. The Cylon version is staying at home to look over my lounge. Indiana is based in my work room. He looks great, I am happy to have him.
Gran Turismo is a wonderful game. If you log in on your birthday you get a car from the year of your birth. Me? I was born in 1972. This is the car I got. Sheer beauty.
This is the store of “things”. You never know when you are going to have to make a rocket or volcano. Just one of those things that you do for your children.
This is my 800th communication on Fooyah.net. As I have been quite angry recently you should be pleased to know that I have taken up paper folding for some of the day to calm me.
This is my armada of planes so far this year. Thanks to Penguin for the gift. Only another 300 or so to go!
If you are a regular reader of these pages you will know that I love playing Gran Turismo on the PlayStation. I always have. My relationship with GT goes back to when it was first released and playing it with my landlord when I lived in Gillingham. GT and Crash Bandicoot are two reasons I bought a PlayStation, or PSOne as it is now known! You can see other communications about GT here and my gallery here it’s been a while since I added new photos to the GT gallery and I should try and do that soon (it’s a quite lengthy process).
Gran Turismo defines itself as The Driving Simulator. Which is probably about right. It’s quite likely to be the most realistic driving game on the market, especially in terms of the physics model it uses. I haven’t played any other driving games really and so I can’t comment. I am also not a racing driver so it would be hard to me to comment on the realism. It amuses me when people describe certain computer games as unrealistic. How would you know? If I was a real racing driver I probably wouldn’t be playing GT.
I recently bought a new home PC. See this communication and the follow up to that. this made me think I could have a flight simulator and I tried installing FSX – The Microsoft Flight Simulator, last version. It turns out that FSX hates Windows 8.1. Some people got it to work and some didn’t. I didn’t want to spend ages digging into why it wasn’t working and the only way I got it to work was to turnoff some graphics function which made it look pretty rubbish on the big screen that I have. So, I had to turn to the only other alternative AFAIK.
X-Plane [I could link to the official site but then you could JFGI]
If you want to see why this is a good program then go no further than Randall Monroe’s What If? blog and see how he used it. I downloaded the demo version and played with it a bit. It is pretty good. You are stuck to the Seattle area in the demo but most of the rest of the game functions well. If you want you can use this program properly and use it professionally. Also around the time of doing this I ordered the X-Plane 10 Global edition. It contains the scenery of the world in it. All of it. I ordered this from the USA website as I didn’t want part of the profits going to a third party seller. It seemed the fairest way to buy it. I didn’t read the small print as I ordered it though. It could take six weeks to arrive. Customs issues apparently.
Here are my tweets.
I’ve ordered @XPlaneOfficial Global edition but I ordered it from the US, over Xmas, I’m waiting. And hoping.
Just read the instructions. It’s 75GB and about 6 hours to install! — Ian Parish (@iparish) December 28, 2014
It looks like I ordered it 8th December and it was waiting for me after I got home on the 28th December. I guess that’s not bad. I’ve also installed a Saitek joystick and throttle (HOTAS) comnbination. I’m currently getting to grips with all the buttons and programming some functions into the joystick.
Here’s a gallery of some of my screen shots so far. I have been tweeting them so you might have seen them before. I’m trying to work with real time and weather in the program so far hence my flights are taking place around the world. I also need to work on my landings. Currently the Sabre is my favourite plane. It’s fast enough to be fun but easy to handle.

I spelt “Harbor” the American way, for accuracy.
I’m quite curious as to whether there is another type of simulation game I would like. On the Megadrive I played a submarine simulation but I would get bored quite quickly and send out a “ping” just to liven things up. I think a nuclear power station simulation would be a bit of a laugh, but then you’d try to recreate the “big ones”, Three Mile Island, Windscale, Chernobyl and see if you could have stopped the outcome. It’d probably take up a bit more technical knowledge than I have and then I’d get kidnapped by some dodgy regime to set up their nuclear program [Oh, no, that’s what Imperial did in the 80s, teach various countries their nuclear knowledge].
I don’t think I would find playing the Sims that exciting. Much like PlayStation Home doesn’t really bother me. I’m not that sociable in real life I don’t what to spend “virtual” time being sociable. I like games that challenge just me. I’ve played SimCity, but I played it once, for about 12 hours, non stop. And then I stopped.
With racing cars and aircraft you can make things happen fast. It’s about getting the timing correct. I’m not that sure that any of the following would bother me much:
