Heavy Metal Chess

January 21, 2017 by Mike Szczys 31 Comments

Chess is a slow game of careful decision-making, looking several moves ahead of the current state of the board. So is machining, and combining the two is an excellent way to level up your machine shop chops. And so we have the current project from [John Creasey] who is machining a chess set out of stainless steel.

This isn’t that new-fangled computer numerical control at work, it’s the time-tested art of manual machining. Like chess, you need to plan several steps ahead to ensure you have a way to mount the part for each progressive machining process. In this first video of the series [John] is milling the knights — four of them, with two which will eventually get a black oxide treatment.

Milling the horse head is fun to watch, but you’ll be delighted when the work gets to the base. [John] is using a pipe fitting as a fixture to hold the already-milled horse-head-end while working the base on his lathe. The process begins by getting rid of the inner threads, then working the pipe fitting very carefully to the diameter of the chess piece for a perfect press fit. Neat!

At the end, [John] mentions it took “quite a few months of weekends to get to this point” of having four pieces made. They look great and we can’t wait to see the next piece in the set come to life. You’ll find the video embedded below, but if you can’t sink this kind of time into your own chess set, you may try three-dimensional laser cut acrylic pieces.

Levitating Table Makes The Sound Of This Holochess Jukebox

November 22, 2016 by Dan Maloney 3 Comments

A bubbling Wurlitzer juke would be a prized addition to the classic picture of a man cave — brass-railed bar, kegerator, pool table, tin signs and neon on the walls. But it would take a particularly geeky abode to give a proper home to this Millenium Falcon holochess table jukebox. And a particularly awesome one at that.

It all started with a very detailed and realistic replica of a holochess table made by [Jim Shima]’s friend. A lot of time and care went into the prop, and [Jim] was determined not to alter the look while installing the media player gear, consisting of a Raspberry Pi running OSMC and a 160-watt power amp.

The speakers were problematic – there was nowhere convenient to mount them except under the brushed aluminum playing surface of the table. The sound quality was less than acceptable, so rather than poke unsightly holes in the table, [Jim] devised a servo to lift the table while the music is playing.

An LCD monitor and wireless keyboard slightly detract from the overall look; we’ll give [Jim] a pass until he can come up with a holographic display to finish the build right. But we are disappointed that he didn’t use “Mad About Me” by Figrin D’an and the Modal Nodes as the demo tune in the video below.

It’s a nice build, and you’ll want to check out [Jim]’s Hyperdyne Labs for more drool-worthy props and effects. And for another fandom jukebox, look over this jukebox that’s bigger on the inside.

Full Size Star Wars Holochess Build

November 19, 2015 by Brandon Dunson 5 Comments

The quality and attention to detail seen in [Ian Martin]’s build is impressive regardless of his choice to build a functioning holochess set. We’re not to take away from the nerd-gasm this build invokes, but we’d rather draw to attention the craftsmanship of the builder. Sadly [Ian] doesn’t have a proper blog or product page but you can view everything he posts about the project on his social networking page and get his take on the finished work in the video below.

This build is not just a well engineered mechanical design, the electronics that run the controls and indicators are [Ian]’s home brew Arduino Mega shields. A complete game requires two sets of electronics, one for each side of the table so rolling his own shield was probably a space saving decision.

Each of the figures used as game pieces were hand sculpted and painted (is that a Rancor to the right?). User controls are presented in true-to-form fashion with 54 buttons, 26 lights, 10 knobs, and an LCD screen with custom bezel to display custom monster status. Nope, the monsters aren’t animated holograms but to make up for that [Ian] built in ambient noises so you know which are still alive. This is our first time discovering that there is a name other than “Holochess” for the game: Dejarik. We’ll leave it up to the reader to figure out how it’s played.

This is an impressive build and we can’t wait to see what else [Ian] comes up with in the future. We have covered Star Wars builds before and some interesting board game builds but never where the two meet before this.

Computer Learns To Hack Chess

October 2, 2015 by Al Williams 15 Comments

A lot of computers can play chess. [Matthew Lui’s] Giraffe is a chess playing computer, but unlike other common chess programs, Giraffe taught itself to play. It apparently learned pretty well, too, since it is rated as an International Master on the FIDE scale (putting it in the top 2.2% of players. The top chess playing computers clock in at super grandmaster level but they are not self-taught).

Make Your Own Ninja Chess Board

July 25, 2015 by James Hobson 5 Comments

You’re going to want to take a look at this fun project [Alistair MacDonald] just finished up. He calls it Ninja Chess.

He’s had the idea to 3D print a complete set of ninjas vs pirates for a chess board, but, let’s be real; printing thirty-two chess pieces would take a long time. He opted to use a laser cutter instead, and so far, only has the Ninja characters drawn. But it still makes for a pretty awesome chess board.

He drew the characters in Inkscape and they’re pretty darn cute. He has all the files available over on his Instructable including the .DXF for the laser cut outlines, and the image files for you to print off the decals. But unless you’re good with scissors, we recommend using your hackerspace’s automated paper cutter to help speed things up.

Is it a hack? Not really, but it’d be an excellent addition to anyone’s workshop. And while we sail under the Jolly Wrencher, we too can appreciate the novelty of a Ninja chess board.

For a more detailed build, did you see the 3D laser cut chess pieces we shared a few weeks ago? No that’s not a typo — you can use a laser cutter to do more than just two-dimensional cutting…

3D Miniature Chess Pieces Made With A Laser Cutter

June 14, 2015 by George Graves 6 Comments

When you think of laser cutters, you generally don’t think of 3d parts. Well, at least not without using something like glue, nuts and bolts, or tabs and slots to hold multiple parts together. [Steve Kranz] shows you how to make these very tiny 3D chess pieces by making 2 passes at right angles to thick acrylic. The first pass cuts one side’s profile, then the part is rotated 90 degrees and a second pass is cut, giving the part more of a “real” 3D look, rather than something cut out of a flat sheet. If you’re having a hard time imagining how it works, his pictures do a great job of explaining the process. He even added some engraving to give the chess pieces for a selective frosted look. We think it’s a cool idea, and well executed too!

But that got us to thinking (always dangerous) that we’ve seen rotary attachments for laser cutters, but they are mainly for etching cylindrical objects like champagne flutes and beer bottle. What if you added a rotating “3rd” axis to a laser cutter that could hold a block of material and rotate it while being cut? (Much like a traditional 4th Axis on a CNC machine). Would the material also need to be raised and lowered to keep the laser focused? Surely software that is aimed at 3D CNC would be needed, something like Mach3 perhaps. A quick Google search show that there are some industrial machines that more-or-less do 3D laser cutting, but if you, or someone you know of, has attached a 3rd axis to a desktop laser, let us know in the comments, we would love to see it.

Lonely? Build Yourself A Chess Robot!

March 15, 2015 by Will Sweatman 30 Comments

[Oriol Galceran] has constructed an interesting robotic chess player for his end of school project. It’s called the ChessM8, and is an impressive feat considering [Oriol] is only 17! He’s using an Arduino Mega that connects to the host PC via a Python script.

The AI can be any chess engine that uses the Universal Chess Interface protocol, which [Oriol] points out that most of them do. We’ve seen other chess robots here before, along with others that you can play on your wall and uses Nixie Tubes. But [Oriol’s] build is the largest of them all.

He says there’s a network of REED switches under the chess board to detect when a piece is present or not. It would be interesting to know how he dealt with debouncing issues, and if Hall Effect sensors might have been a better choice. Let us know in the comments how you would detect the chess piece.

And be sure to check out the video below to see the chess robot in action.
