An elegant twist on the 7-segment display

We featured an earlier iteration of this seven-segment display in the middle of 2020, and it was pretty clear then that, even at an early stage, it was a brilliant idea. Its creator, Neeraj Rane, said at the time that he wanted to minimise the size of the electromagnetic actuators that move the seven segments in and out, and he’s done that by ditching discrete components, and instead printing the coils of the magnets onto the PCB. This method, inspired by the work of Carl Bugeja, has resulted in a slimmer, more useful creation, in a 3D-printed body.
