Figured we should do a #projects post, and share some of what we've built in the past.
All our projects get a catalogue number - ibalXXX. We use that as a hashtag here and if they're public, they'll also have a page on our website, again mcqn.com/ibalXXX and be listed in the catalogue https://mcqn.com/catalogue/
Everything gets a number, from internal things (like our logo #ibal3), to client work (e.g. #ibal171), talks (e.g. #ibal204), or products (such as #ibal234)
Let's start with a festive one. Back in 2017 we worked with artist Simon Armstrong to decorate the Christmas tree in Liverpool city centre.
It had 32 geometric light baubles, and around the base were six touch panels which passers-by could use to change the light patterns.
It used 170m of RGB LEDs, and a 240A (at 5V) power supply (we'd have liked even more!)
'Tis the season to share PixelCheer, one of our #projects.
FACT, a gallery in Liverpool, has a huge LED facade above their entrance. We worked out how to control it for an earlier project, so for Christmas 2014 we connected it to the Internet.
Folk using the #Cheerlights hashtag could change a colour on the image displayed, and we worked with a bunch of pixel artists to create 16 different images chosen with different hashtags.

@MCQN_Ltd where do you even get a 240A 5v supply?
@coldclimate RS. Ideally we'd have had a second, then we could've lit up all the LEDs. As it was we wrote some code to light all the odd-numbered LEDs and then all the even-numbered ones, as quickly as we could and so it *looked* like they were all illuminated, but not as bright as they could've been.
The Council could only get us a 10A mains feed from one of the lampposts in the square, which was what capped us at 240A.
It's got very chunky bus bars that you bolt connections to
