Hackaday Podcast 008: The Art Episode: Joe Kim, Strings And CRTs, Hydrogen Done 2-Ways

We know you love the original art on Hackaday. Those fantastic illustrations are the work of Joe Kim, and he joins us as a guest on this week’s episode to talk about his background, what inspires him, and how he pulls it all off.

This episode is still packed with hacks. Editors Mike Szczys and Elliot Williams somehow stumble into two projects that end up generating hydrogen (despite that not being their purpose). But that art angle this week goes beyond Joe’s guest appearance as we look at a hack to add green curve tracing goodness on a black and white CRT, and an incredible take on a string art building machine. We get a look at interesting hardware that landed on the clearance rack, ultralight robots that move with flex PCB actuators, a throwback to mechanical computing, and giving up control of your home heating and cooling to a Raspberry Pi.

  1. Finally managed to catch the podcast not long after the release :-)
    It’s a shame that the podcasts don’t seem to get more love as there were a few tidbits that were mentioned that weren’t in the original article and were details that I’d missed so hearing the call-backs is handy.

    On the I2C addressing, some devices allow the configuration pin to have 3 states (tie to +v, tie to 0v or leave open/nc) that way with two address selection pins you can actually get 9 different addresses which is quite a lot to avoid conflicts (but if that’s not enough, there’s always address translation chips – which I think HaD has covered in the past). An alternative to sharing the clock line with multiple data lines (not always an option with hardware I2C controllers) is using an I2C buffer/isolator/translators which, along with voltage translation, often have an enable pin or at least design examples that show how they can isolate one side of the bus from the other.
