Delcom Light is one of the best indicator lights that you can purchase nowadays.

You can see a picture of the light here:

• OSX

• Linux

• Windows

Any server that supports the cctray xml format, including among others:

• Go - watch go-server:8154/go/cctray.xml

• Jenkins/Hudson - watch jenkins-server:8080/cc.xml

• travis - watch api.travis-ci.org/repositories/owner/project/cc.xml

• tddium - watch ‘Configure with CCMenu’ (something like api.tddium.com/cc/long_uuid_string/cctray.xml)

Install lib-usb-1.0 with your favourite package manager, and then install the blinky gem

For example, on OSX:

brew install libusb

on Debian or Ubuntu:

apt-get install libusb-1.0-0-dev

and so on

Windows can be a bit fiddly. The following is how I got a Delcomm II light to work on a Windows 7 laptop. Further experience reports/better instructions would be gratefully received.

• installed Zadig (github.com/pbatard/libwdi/wiki#wiki-Downloads)

• plugged in the USB light

  • at this point windows ‘helpfully’ installed an incorrect ‘USB Input device’ driver

• opened Zadig and selected ‘Options -> List All Devices’

• Selected ‘USB Input Device’ in the Zadig drop-down

• Clicked on ‘Replace Driver’ and confirmed in the popup dialog

• installed the blinky gem

If you are using rb-env, it’s super simple. Just run:

bundle install

And you are good to go. Otherwise, go install each gem in Gemfile one by one.

Change the chica.rb file if you want to filter out projects you want to see failing. And run;

chicanery chica.rb

It’ll light red if any of the given build ids fail, amber for errors on any build and for the rest it’s green.

It will periodically(every 5 seconds) run it.
