There’s no doubting the allure of a nicely crafted LED cube; likewise, there’s no doubting that they can be a tremendous pain to build. After all, the amount of work scales as the cube of the number of LEDs you want each side to have, and let’s face it – with LED cubes, the bigger, the better. What to do about all that tedious lead forming?
[TylerTimoJ]’s solution is a custom-designed lead-forming tool, and we have to say we’re mighty impressed by it. His LED cubes use discrete RGB LEDs, the kind with four leads, each suspended in space by soldering them to wires. For the neat appearance needed to make such a circuit sculpture work, the leads must be trimmed and bent at just the right angles, a tedious job indeed when done by hand. His tool has servo-controlled jaws that grip the leads, with solenoid-actuated lead formers coming in from below to bend each lead just the right amount. The lead former, along with its companion trimmer, obviously went through a lot of iterations before [TylerTimoJ] got everything right, but we’d say being able to process thousands of LEDs without all the tedium is probably worth the effort.
We’re looking forward to the huge LED cubes this tool will enable. Perhaps this CNC wire bender and an automated wire cutter would come in handy for the supporting wires?

Drop what you’re doing and get thee to thy workshop. This is the last weekend of the Hackaday Circuit Sculpture Contest, the perfect chance for you to exercise the creative hacker within by building something artistic using stuff you already have on hand.
The concept is simple: build a sculpture where the electronic circuit is the sculpture. Wire the components up in a way that shows off that wiring, and uses it as the structure of the art piece. Seven top finishers will win prizes, but really we want to see everyone give this a try because the results are so cool! Need proof? Check out all the entries, then ooh and ah over a few we’ve picked out below. You have until this Tuesday at noon Pacific time to get in the game.

555 Spider by Sunny
Freeform RGB Atari Punk Console by Emily Valesco
These are just three awesome examples of the different styles we’ve seen so far in the contest. Who needs a circuit board for a retro computer? Most people… but apparently not [Matseng] as this Z80 computer is freformed yet still interactive.
Really there can’t be many things more horrifying than the thought of spider robots, but somehow [Sunny] has taken away all of our fears. The 555 spider project takes “dead bug” to a whole new level. We love the angles in the legs, and the four SMD LEDs as spider eyes really finish the look of the tiny beast.
Finally, the 3D design of [Emily Valesco’s] RGB Atari Punk Console is spectacular. It’s a build that sounds great, and looks as though it will hold up to regular use. But visually, this earns a place on your desk long after the punky appeal wears off. We also like it that she added a color-coded photograph to match up the structure to the schematic, very cool!
What are you waiting for, whether it’s a mess of wires or a carefully structured electron ballet, we want to see your Circuit Sculpture!
