Layout vs Display

  By: ijl20 on July 11, 2018, 10:18 a.m.

Hint for those out there creating their own custom SmartPanels, derived from a slight misunderstanding I've noticed...

While you develop your carefully designed grid layout of selected widgets, you can hit the VIEW button and see how your creatio...

Operational Issues Updates

  By: ijl20 on July 10, 2018, 5:03 p.m.

Today Tues 10th July the Weather data feed from the UK Met Office seems to be royally broken. So the weather widget on the SmartPanel will be blank when it refreshes. Nothing we can do about this at the moment except inform the Met Office.

as of...

Re: Support for Portrait Layouts?

  By: ijl20 on July 9, 2018, 9:29 p.m.

obviously sounds reasonable and we'll add it to the list. Don't get me started on 'Doh' as the fixed layout was a considered choice to deliver what we did. There are quite a few other 'small' improvements we intend to make but maybe we can put a ...

Re: Bus Live Data Map

  By: ijl20 on June 28, 2018, 8:59 a.m.

In due course we'll get around to providing the next version of that bus map - for the past several months the main 'development' focus has been the SmartPanel with a combination of the layout framework, the multiple widget design, and also the d...

The essential concepts are:

Widget: this is a layout component that shows information about a particular thing, e.g. the Weather, or a Train Station.

Layout: this is the particular choice and configuration of widgets that makes up your preferred...

Re: Histon Rd

  By: ijl20 on June 12, 2018, 3:25 p.m.

I'd need to go through the process of rendering the new zone on a map and comparing it to the previous one - the essential question is whether this zone alters the transit time for the existing buses or not, i.e. have the start/finish lines moved?...

Re: Class C operation

  By: ijl20 on Feb. 23, 2018, 10:13 a.m.

All the sensors on the network so far have been uplink only (i.e. the typical transmission of sensor data to a server), so if you have a downlink requirement it's best we collaborate for these first ones... the advantage is we can use our internal...

Re: Smart city in a week - Cambridge project

  By: ijl20 on Feb. 23, 2018, 10:07 a.m.

So far we've registered 30 devices and have the first one sending humidity and temperature data to SenSat - I look forward to seeing what this project produces.


Re: Are there any public/open data sources available for cambridge?

  By: ijl20 on Jan. 22, 2018, 3:09 p.m.

Good question...

For a wide variety of digital data repositories, there's Cambridgeshire Insight

This site is more focussed on the kind of data we'd want to collect in real-time, and your 'climate change' question is likely to include that sort...

Re: Bus Live Data Map

  By: ijl20 on Jan. 22, 2018, 2:49 p.m.

Apologies for a spectacularly delayed reply. If you'd like a feeble excuse it's that we're deeply buried in significant enhancements to the bus side of the platform...

For others reading this we're talking about the live 'real-time' bus map here:...

Re: Milton Rd

  By: ijl20 on Oct. 21, 2017, 11:52 a.m.

do you want to draw a polygon for Milton Road that would be preferable for analysis? For the 10 in/out zones we have already (i.e. 20) I hacked together a tool to draw the zones on a map, with the coordinates accumulating as text below the map yo...

Re: ts_delta

  By: ijl20 on Oct. 21, 2017, 11:17 a.m.

thanks - good question... I'll answer it within the broader context of calculations the Zone is doing in real-time:

TL;DR: ts_delta is the sum of the lengths in seconds of the entry vector and exit vector of the vehicle that successfully transite...

Re: CSN coverage map (as of July 2017)

  By: ijl20 on Oct. 20, 2017, 1:25 p.m.

Is there any way you can host this map on the site so it can be played with?

The map has been implemented as a web page which may in due course make its way onto the SmartCambridge platform, with the idea that the Cambridge Sensor Network cov...
