DIY: Air Quality Balloons

I found this post not too long ago and have been wanting to make one of these ever since. What’s making these balloons glow is the pollutants in the air around them, with colours ranging from green (signifying excellent air quality) to red (poor air quality).

LED Shadow Clock

Justin, this reminds me of something you might have done with your LED/Arduino knowledge.

Quick Update: LEDs Survived, Postcards are Being Distributed!

Just a quick update…the LEDs in the freezer are still going strong, more than two days later, which is good news for any potential LED-embedded ice or snow project. The glow was way more exciting than this photo makes it appear, as I had assumed the battery wouldn’t have lasted this long at all. Finally had […]

Snow, LEDs, Flights, Fill-in-the-blanks, Proofs, and Postcards

Meeting twice in a week is awesome. I can’t say that enough. So much time makes us way more productive and makes it a lot easier to be OK with not having everyone there all the time. First on the list, doing some really, really quick tests of the potential of embedding LEDs in ice […]

The LED Sign is Finished!!!

It’s taken a number of weeks, but we finished wiring the LED sign at tonight’s Office Hours! It was a pretty incredible moment to plug in the sign, turn off the lights, and realize that we made this come together. I’m really, really, really happy with how it turned out!!! There are still a few […]

LED Graveyard

I went through our LED sign today and removed all the LEDs that had died in our earlier efforts to learn electricity. So now we’re ready to replace these and finish up the sign! 12 out of nearly 200 LEDs isn’t too bad.

Moving Along with Flagging Tape and LEDs

Broken City Lab Office Hours on Tuesday were hugely productive. We completely finished getting all the resistors on the LED sign, measured out all the letters with flagging tape for the EC Row Project, organized some logistics for the planning stages of a couple other upcoming projects, and figured out the title for our upcoming […]

We Learned Electricity!

We’re in week 3 of this LED sign project, and we now know how to finish it up. We had previously soldered all the anodes on the LEDs, but we were a bit confused about the connections of the cathodes and resistors. As we had been working off of a MAKE video, which breezed over […]

Continuing Work on the LED Sign

Michelle and I finished soldering the anodes on the LED sign yesterday morning. Next is soldering all the resistors to the cathodes—this is a hilariously longer process than I think any of us anticipated, but it’s good. I’m really looking forward to seeing it lit up! Also, thank you to whoever passed on the big […]

Fence Text + LED Soldering

Broken City Lab Office Hours last night were hugely productive due, in no small part, to the many amazing people around the table last night. We completed a test with the flagging tape at Lebel (as you can see above) for the EC Row project and continued working on the LED sign. There’s lots of […]
