Visitor project: Dominion storage solution

Dominion is an award-winning deck-building card game that has ten expansions released as of this writing. There are a wide variety of proposed storage solutions to the problem of toting about several thousand cards and sundry mats and tokens, and Sherwin decided it was high time he moved on up from the method he had been using to a proper receptacle.

First, a look at the final product:

Wooden box sitting on its edge with the word "Dominion" etched in stylized text on its face. Open wooden box displaying contents consisting of rows of Dominion cards separated by labeled dividers.

We managed to fit about 3700 unsleeved cards along with the other odds and ends in with room for further expansion. The dividers make every card easy to locate and access, and the box dimensions keep the whole package relatively compact and portable.

Our starting point was an ad-hoc solution that involved storing each set of Kingdom cards in separate pockets on 9-card sheets, with the base cards being held in deck boxes and the tokens in a bead container, all of which were piled into one of the original game boxes and wrapped in a tote bag. This system worked for a time, but as further expansions were released, both box and tote showed increased signs of strain, neither having been designed to hold more than one game or expansion at a time.

The sheets can be seen overflowing from the game box, which barely squeezed into the tote

The box had already been replaced once before, and when the replacement itself began showing severe signs of wear we began looking into other options. We debated building one out of lumber, but eventually settled on using a case that had been tried and tested in other storage solutions for our first attempt.

We knew that we would require some sort of organizer to keep each column of cards in line, and laser-cut some test pieces out of cardboard to check the fit.

Determining the dimensions of the caddy and how to fasten them

Seen from above, the right half of a wooden table is covered in two disjoint halves of a wooden box, the left is covered in white paper. Strewn over everything is a set of cardboard inserts which are white on one face and brown on the other. Wooden box with cardboard inserts fills the page. There one small stack of Dominion cards sitting in each of the six columns.

We also planned to engrave the game’s logo onto the box using the laser cutter, and had two waxes and two stains we wanted to try. The case came with a tray insert that was made of the same wood, though unfinished, so we did a test burn both before and after applying the four coats to observe the effect. We also removed the hardware from the case and sanded off the veneer in preparation.

Blue nitrile gloved hands which come from the right side of the frame are rubbing dark wax into one of four rows on a wood box which sits on white paper. Wooden box with the words "Hello world" etched in four rown down the left side, sits on white paper with a bright light shining down on it. The wood has been stained in four rows with increasingly dark wood stains / waxes going from a golden honey colour to a brushed black hue.

The logo we used had too much background and shading for a clean burn. We ended up using Pawel Pawlak’s Dominion icons to generate an appropriate vector image of the logo and banner outline for the laser cutter.

Testing the final logo
After finalizing the dimensions of the caddy pieces and wax choice, we then cut the pieces out of clear acrylic, assembled and affixed them with acrylic glue, burned the logo into the case cover, then applied the coats of wax.

The box is divided into six columns by strips of clear acrylic which are the same height as the box itself. An additional strip of clear acrylic rests atop the left edge of the box hanging prosperously over the side.

Two hands connected to arms which lead off the top of the picture, are wearing blue nitirle gloves and rubbing additional wax into the surface.

Applying the wax to the case exterior

To minimize cards sliding around and give them a cushion, we cut a segment out of poker felt and glued it to the bottom with spray adhesive. We attempted to replace the stock hardware with sturdier options, but found the wood to be too thin to support any of the screws from the cabinet fixtures.

A rectangular wooden pallet has two small squares of green felt glued to the bottom right corner of the palette. A jug of wood glue, can of spray adhesive, and hand holding a hot glue gun are just out of frame. Light wooden box with a green felt base rests on its edge, filling the frame. The box's inside is divided into six vertical columns by clear acrylic. Two hands in the upper right of the frame can barely be seen screwing something into its side.

Testing different adhesives on felt samples and reattaching the hardware to the finished bottom
Finally, after completing assembly of the box, we had to transfer the actual game components from the old box to the new one. We created the divider tabs using sumpfork’s Dominion Divider Generator and had them printed on cardstock and trimmed at a local print shop.

Brass clasps are affixed to its front along with a leather and brass handle. Open light brown wooden box resting on butcher paper on a wooden table.

Resting atop a wooden table which fills the frame, from left to right there is a stack of two sheets of card sleeves full of Dominon cards, the bottom half of a Dominion box full of card sheets which are them selves full of Dominion cards, the top half of a Dominion box with three stacks of dominion cards, a light wooden box which is open, with a green felt bottom split into six columns by strips of clear acrylic, one of the columns is full of dominion cards with a second one about half full, and finally five stacks of white card paper which are barely in frame. On the right side of the table there is also a jumble of empty card sleeves. A wooden table runs at a sharp angle from the top left to the bottom right of the frame. From left to right there are: sheets of card sleeves full of dominion cards, the bottom half of a dominion box half full of full card sheets, the top half of a dominion box with three stacks of dominion cards in it, a light wooden box which is open, its base green felt, divided into six columns by clear acrylic the left most of which is full of dominion cards and dividers, finally six stacks of white card stock with dominion rules text printed on them.

Moving the cards into their new home
A light wooden box sits dead center, filling the bottom half of the frame. Its open lid fills the top half. The box is filled with dominion cards arranged in four of the six columns and separated by white card stock with card titles. The second to left column contains little plastic bags of glittering bronze tokens, and the last column is about half full of cards separated in the same manner as the first four.

Ready to play!

Visitor projects: the most excellent blanket

Hey NYCR visitors – have you done something neat lately? Let us know, so we can blog about it!

Julia learned to knit in December at NYC Resistor. And then, uh….this blanket happened. Julia, you’re amazing. Students outshining their teachers, etc.

I can vouch for this blanket being extremely cozy. You’re looking at 30 skeins (6,540 yards!) of yarn and 1,040 tails that needed weaving in. It comfortably fits three people.

If you want to make your own blanket, the Infinite Rainbow Throw pattern is free from KnitPicks.

Don’t know how to knit? Wish you had more knitting time? Join us every other Monday for our Knit Knight, 730pm-930pm. We’ll teach you – beginners get their first pair of needles free. (You don’t need to be as intense as Julia in order to attend Knit Knight, we promise.)

Interactive Show Preview: Who Do You Love


Come to the NYC Resistor Interactive Show this Saturday to see “Who Do You Love” by Adelle Lin, Olivia Barr, and Matt Pinner:

A deplorable reality television host rises to power by exploit people for the sake of entertainment. He uses a nightmarish cacophony of violence and catch phrases to control his audience. In The Running Man this media mogul shouts, “Who Loves You and Who Do You Love?”

Who Do You Love is an interactive sound installation that samples Donald Trump saying the word “China” in phrases from his campaign and presidency. The interface device for the installation consists of three acrylic towers, dispersed through the space. Each tower houses three buttons where players can activate the sound from different locations. Pressing a button triggers the Commander and Chief to say “china”, “i love china”, “i know china very well”, or “china all the time”.


The phrases overlap each time a button is pushed to create an ambiance of garbled memetastic catch phrases. The towers encase a teensy audio shield, teensy 3.2, xbee, and our custom oshpark pcb. the devices connect to each other using these 900mhz xbee radios and light up clear acrylic portions with led sequins when buttons are pressed anywhere in the space. The new echo of “China” is channeled into the exhibition room’s speakers or through headphones. Multiple players of Who Loves You collaborate to compel the distortion of Trump’s reflections on China into noise.

We hope this raises some discussions about your feelings around entertainment media and representative governments.

Laser cut Fractal Puzzle

Team effort

THe Gosper Curve is a self-similar fractal that can be turned into a visually interesting, yet very difficult puzzle on the laser cutter. With all of the pieces the same color it is nearly impossible, but a bi-color version is a doable challenge. You can move the slices (in blue in the SVG file) around to vary the puzzle or change the difficulty; the current version has lots of very similar pieces to make it full of “garden paths” that require frequent back-tracking when the solution almost works.

ShopBot Furniture Making by a Woodwork Dilletante

Recently, I moved to a new apartment, and this presented me with a problem. You see, some years ago, my wife and I bought a nightstand when we had space for just one of them. Now, we have space for two, so we needed a second one. Of course, that nightstand has been discontinued for years and years. We could have purchased two new nightstands, but that seemed like a waste. Fortunately, we have a ShopBot and a supply of plywood – so I took it as a challenge to make a nightstand that was as close to the original as possible.

A nightstand that is now discontinued.

The original nightstand, made by a retailer popular with recent college graduates, that isn’t Ikea.

There were some design requirements from the outset:

  • The finished piece has to look very close to the original.
  • The finished piece must not have rough edges or visible joinery, just as the original doesn’t. My own tolerance for plywood furniture where the edges of the wood are visible is quite high, but my wife’s isn’t.
  • The finished piece should hold up as a daily-use piece; it should be solidly built.

I started out by taking dimensions from the original and then modeling it in Fusion 360:

I started out with just the faces, without any joinery. Next, I added in tab-and-slot joints, with idealized corners–that is to say I didn’t include the fillets that let the tabs actually fit together. Adding the tabs is kind of a tedious, manual process, but the best way I’ve found to add them all in is detailed in this YouTube video.


Once I had everything laid out in Fusion 360 I exported the vectors for each part to a .DXF and exported it over to VCarve to define toolpaths. I know that Fusion has a full-featured CAM suite, but I’ve found that VCarve is slightly better suited to the ShopBot–it has everything I need and nothing that I don’t. At this stage I laid out all the parts on one sheet of 1/2″ plywood and added the fillets to all the interior corners, as well as hold-down tabs.

Then it was time to actually run the cut, which was probably the easiest part of the entire operation.


Once that was done, it was time to part the pieces off from the parent stock with a hammer and chisel, then sand down the flashing left over from the hold-down tabs.

Next, I dry-fit the whole thing together to make sure everything lined up the way that I expected.


I found a few tight spots in some of the pockets for the tabs which I had to sand down — the tabs and slots were drawn to be a precise fit, so a little bit of irregularity in the wood surface can cause a very tight fit. Once I was convinced it all fit together, I glued it all up and clamped the assembly together overnight. Unfortunately I didn’t have clamps long enough to get all the way around the parts so I had to rely on gravity to do some of the job, which ultimately resulted in a couple of gaps, though fortunately they are hard to spot. I was happy to see that the fillets on the corners the tab pockets were almost invisible as well.

That’s a bucket of sand.


Once the glue had fully cured overnight and the clamps were off, I set about applying edge-banding. Edge banding is a notorious pain to apply properly, and to make matters worse, I couldn’t find any locally that was close to half-inch, so I had to spend quite a bit of time with a blade, block plane, and sander to get all the edges flush. I found this video by The Wood Whisperer to be a helpful guide, since I’d never used edge veneers before.

Once I’d trimmed and sanded the veneers, it was time to move onto finishing. This was by far and away the most tedious and tricky part of the build, and the one where I made the most mistakes. I went with Minwax Polyshades in Espresso, which appeared from the samples to be about the shade I was looking for. In order to get anywhere close to the right shade (which was, frankly, still too light by the end) I needed four coats.

After the first coat, it looked like this:

The finish was really hard to control, and tended to go blotchy and drip very easily; I forged on, hoping that further coats would smooth things out. Once the first coat had cured overnight I gave it a once-over with #000 steel wool and then added another. After the second coat, the color deepened and looked like this:

After the third coat, it looked like this:

And after the fourth coat, it looked like this:

The shade was still a bit light, but the surface finish was very shiny and I thought that adding a fifth coat would turn everything into a plasticky mess so I stopped at four.

I added the drawer rails:

And then installed the drawer

And there we go! Here it is in situ. The dog was a bit mystified:

So, what did I learn – what went well, and what could have gone better?

What went well:

  • It’s absolutely possible to use the ShopBot to create professional-looking furniture – at least as far as the cutting and joinery goes. The key things here are the blind pockets for the joints and slightly proud top and base that help to hide the fillets which are often the hallmarks of CNC furniture.
  • The result is sturdy – it’s not wobbly in any axis, and the frame holds up nicely to shearing forces without bending.
  • The edge veneers look pretty decent. I could use some more practice in getting them straight, and the corners are the most obviously-dodgy bits, but I think they came out well. They’re another key to making plywood look like real wood boards.

What didn’t go so well:

  • The surface finish isn’t that terrific.
    • There are some dust particles trapped between layers of polyurethane which I should have caught. I think they might be fragments of steel wool from between coats.
    • If I was choosing a finish again I would have gone with a traditional stain and then two or three layers of polyurethane, probably in a satin or semigloss finish rather than this straight-up gloss. Having the darkness and shininess tightly bound to one another makes it very hard to get the finish right. It’s also a recipe for mess-making since everything is very thin and runs all over the place.
    • The finish, as mentioned, is a bit light – staining separately would have let me control that more precisely. I probably should also have done some test runs of the finish before applying it to the final production piece.
  • There’s more of a gap than I’d intended between the top of the drawer and the top of the table. I must have mis-measured at some stage. I should have have the ShopBot pre-drill the pilot holes for the rails. I don’t know what I was thinking.
  • Using just tab-and-slot construction and glue was probably a bit aggressive, since “no fasteners” wasn’t in the goals I set out for myself. It would probably have been fine to sneak in a few screws here and there to keep everything flush and in line, and nobody would have been any the wiser.

If you’d like to try this out yourself, I’ve made Fusion data available here.

I’m looking forward to building more furniture now that I’ve made a bunch of mistakes and can avoid them next time around. I’d also love feedback about other pitfalls! Give me a shout on Twitter or in the comments.
