The Most Expensive D20 You’ll See Today

Roll your negotiation skill, because this d20 is a hefty one. The Tweet is also below. We are charmed by [Greg Davill]’s twenty-sided LED contraption, but what do we call it? Is it a device? A sculpture? A die? Even though “d20” is right on his custom controller PCB, we don’t think this will grace the table at the next elf campaign since it is rather like taking a Rolls Royce to the grocery store. Our builder estimates the price tag at $350 USD and that includes twenty custom PCB light panels with their components, a controller board, one battery pack, and the 3D printed chassis that has to friction-fit the light faces.

Power and communication for all the panels rely on twenty ribbon cables daisy-chained throughout the printed scaffolding, which you can see in the picture above. [Greg] made a six-sided LED cube last year, and there are more details for it, but we suspect he learned his lesson about soldering thousands of lights by hand. There are one-hundred-twenty LEDs per panel, times twenty, that is over two-thousand blinkenlights. We don’t yet have specs on the controller, but last time he used a SAMD51 processor to support over three-thousand lights. We don’t know where he’ll go next, but we’re game if he wants to make a chandelier for Hackaday’s secret underground lair.

(Editor’s Note: If you were at Supercon last year, and you got to play with this thing in the flesh, it’s worth it!)

Building The Scoreboard Of Your Imagination

It might seem like electronic games and tabletop games are somewhat at odds. But there are always places where the lines are cleverly blurred as with this stat tracker beautifully constructed from a sandwich of circuit boards.

The nature of role playing games is one of deep imagination, putting yourself in the shoes of the player your are building though out a campaign. But of course the game board and pieces are there to keep track of all the data that your imagination just can’t. This can be done with a character card and some markers, a pad of paper, or a spreadsheet on your laptop. But to keep his mind in the world of Hyper Light Drifter, [Albert Phan] built this stat tracker that lives up to the aesthetic of the game.

The stackup of three PCBs does a brilliant job here, using cutouts on either end of the faceplate as a flexible tab that you press to actuate the surface mount button on the bottom PCB. The third PCB act as a spacer, not just for the six low-profile buttons, but also for the 40 LEDs that display status. That spacer has holes cut out for each light, providing isolation, with the FR4 substrate of the top plate acting as a diffuser.

It looks spectacular, it saves state between uses, and can be recharged via USB. But what’s that you say? You don’t play Hyper Light Drifter? Just respin the top PCB (and we suppose you’d need to tweak firmware as well) and you can swap it out for your game of choice.

Dungeons And Dragons TV Tabletop!

With little more than pen, paper, dice, and imagination, a group of friends can transport themselves to another plane for shenanigans involving dungeons and/or dragons. An avid fan of D&D and a budding woodworker, Imgurian [CapnJackHarkness] decided to build gaming table with an inlaid TV for their inaugural project.

The tabletop is a 4’x4′ sheet of plywood, reinforced from underneath and cut out to accommodate a support box for the TV. Each leg ended up being four pieces of 1’x4′ wood, laminated together with a channel cut into one for the table’s power cable. An outer ledge has dice trays — if they’re even needed in today’s world — ready for all those nat 20s, cupholders because nobody likes crying over spilled drinks, and electrical outlets to keep devices charged. Foam squares cover the tabletop which can be easily removed and washed if needed — but more on that in a second. [CapnJackHarkness] painted the table as the wood rebuffed many attempts at staining, but they’re happy with how it turned out.
