Board with Tech – 7:00 PM to 10:00 PM Wednesday 27th March 2017

Hosted by David H. from The Basingstoke Tech Scene

The board game nights  at Basingstoke Makerspace have been going well, so we’re doing another one! The concept is simple, turn up, bring a game if you would like, and we all sit down and have some fun. We can’t promise everyone’s game will be played, so be prepared to join in with another group. Also we suggest games around 1 hour in length, they normally take 1.5-2 hours once the rules have been explained anyway.So whether you enjoy exploding kittens, want to start a pandemic or feel like going sub terra, come and join us for a night of gaming. Finally, please bring whatever you would like to eat or drink for the evening. Those that are interested can also club together for a pizza order on the night.

Tuesday Open evening talk about Crossrail Signalling

Last Tuesday at Basingstoke Makerspace many of the members and some visitors sat down to an interesting talk by Kevin Roche about railway signalling in the UK and its use on the new Crossrail aka ‘The Elizabeth Line’.

Crossrail will run from Reading and Heathrow through new tunnels under London to Shenfield and Abbey Wood.

Kevin explained how railway signalling had developed in the UK following a terrible rail crash at Harrow and Wealdstone in 1952 where 112 people were killed and 340 injured.

Following that crash and others several different solutions were developed to avoid similar crashes in the future. The aim being stop trains passing red signals or exceeding the recommended speed limits.

As a result, the new Crossrail service being built is required to work on railway lines equipped with several different signalling systems known as AWS, GW-ATP, TPWS, ETCS Level 2 and Trainguard MT.

After a detailed review of each system, Kevin explained that trains on Crossrail will switch automatically between three of the signalling systems as they travel along the new route. In the eastern sections they change over while in Stratford station, but in the western section they have to change over while moving.

There has been trouble, however with interfacing the older systems designed in the 1950’s with the latest technology that allows the new trains to run as many as 30 trains per hour.

It is thought that the line will not open now until 2020.

CrossRail Signaling – 5 March 2019 7:30pm

Where is my Train? – A talk by Kevin Roche

The Elizabeth Line was supposed to be running through Central London by December 2018 but it isn’t. Many people are blaming the complex signalling systems. Are they right?

Did a small problem in Mid Wales cause a more than one-year delay in Central London?

What went wrong with Crossrail’s Signals?

I will give you an easy to understand introduction to railway signalling and how it has developed in the UK.

What it means for finalising the Elizabeth Line and getting the trains to run.

Tethering a camera to laptop

Photography Interest Group – Tethering Workshop – Monday 18th February at 7pm

Amateur photographers are often unaware of the benefits of tethering to a computer. Digital images can be almost instantly viewed  on a larger screen once you tether to a laptop or tablet. You can spot issues with focus, lighting, posing or composition and reduce post processing using such rapid feedback. 

Join us at the Makerspace at 7pm on Monday 18th February for a workshop that will highlight the practical advantages and disadvantages of tethering. We will compare  software solutions in terms of purchase costs and features as well as demontrating several working systems

7:30 pm Monday 15th October –   Photography Interest Group –  Water droplets! .

On Monday 15th October the photography interest group spent an evening photographing  water drops.

 

David who took the above picture said: “On Monday Basingstoke Makerspace held a ‘photographing drops’ session. I think this is my favourite shot of the night from my camera.
It’s also given me an idea for a project I want to try.”

 

 

We used  a Speed-light flash and a Pluto trigger together with a triggered drop release mechanism to produce reproducible drops.

 

After a falling water drop splashes into  a bowl of water  a crown is forme  from displaced water. the bulk of the drop remains intact and enters the water. In the following picture  the crown can be seen with  a second drop timed to fall artistically just above the crown.

 

 

 As the initial drop enters the water in the centre of the crown it displaces water in the bowl upwards. This  slows the drop’s downward speed until it stops. At this point it starts to moves up  pushed by the displaced water.  When it reaches the surface it breaks out of the  surface with surface tension forming  a stalk with some fraction of the original drip on the top.  The remains of the crown can be seen spreading out.

 

 

 

 

We then added a second drip to collide with  the upward rising stalk from a previous drop. When the two collide
