Circuit Sculpture Hack Chat

Join us on Wednesday, November 6 at noon Pacific for the Circuit Sculpture Hack Chat with Mohit Bhoite!

For all the effort engineers put into electronic design, very few people ever get to appreciate it. All the hard work that goes into laying out a good PCB and carefully selecting just the right components is hidden the moment the board is slipped into an enclosure, only to be interacted with again through a user interface that gets all the credit for the look and feel of the product.

And yet there are some who design circuits purely as works of art. They may do something interesting or useful, but function is generally secondary to form for these circuit sculptors. Often consisting of skeletons of brass wire bent at precise angles to form intricate structures, circuit sculptures are the zen garden of electronic design: they’re where the designer turns to quiet the madness of making deadlines and meeting specs by focusing on the beauty of components themselves and putting them on display for all to enjoy.

By day, our host Mohit designs and builds hardware at Particle. By night, however, the wires and pliers come out, and he makes circuit sculptures that come alive. Check out his portfolio; you won’t be disappointed. This Hack Chat will be your chance to find out everything that goes into making these sculptures. Find out where Mohit gets his inspiration, learn his secrets for such precise, satisfyingly crisp wire-bending, and see what it takes to turn silicon into art.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, November 6 at 12:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about. Continue reading “Circuit Sculpture Hack Chat”

Solar Circuit Sculpture Pumms The Night Away

A word of warning: Google for the definition of the word “pummer” at your own risk. Rest assured that this beautiful solar-powered circuit sculpture fits the only definition of pummer that we care to deal with.

For the unfamiliar, a pummer is a device from the BEAM style of robotics, a sort of cyborg plant that absorbs solar energy during the day and turns it into a gently pulsating light that “pumms” away the dark hours.

[Mohit Bhoite]’s take on the pummer is an extraordinary model of a satellite executed mainly in brass rod. His attention to detail on the framework boggles our minds; we could work for days on a brass rod and never achieve the straight lines and perfect corners he did. The wings support two solar cells, while the hull of the satellite holds a dead-bugged 74HC240 octal buffer/line-driver chip and all the other pumm-enabling components. A one farad supercap – mounted to look like a dish antenna – is charged during the day and a single LED beacon blinks into the night.

No schematic is provided, but there are probably enough closeup shots to reverse engineer this, which actually sounds like a fun exercise. (Or you can cheat and fetch the PDF copy of the old Make magazine article that inspired him.)

Hats off to [Mohit] for a top-notch circuit sculpture. We’ve seen similarly detailed and well-executed sculptures from him before; something tells us this won’t be the last.

Thanks to [Varun Reddy] for the tip.
