An Open Source Client For World Of Warcraft

February 18, 2026 by No comments

When World of Warcraft was launched in 2004, it became somewhat of a juggernaut in the MMORPG space. Millions of players continue to login every month. [Kelsi Davis] is one such player, but she doesn’t always log in with the regular client anymore. That’s because she put together WoWee—an open-source alternative of her very own.

WoWee is an acronym—World of Warcraft Engine Experiment. Coded in native C++, it’s a homebrewed client that uses a custom OpenGL renderer to display the game world. [Kelsi] notes that it’s strictly an “educational/research” project, built without using any official Blizzard assets, data or code. Instead, it grabs some client data from a legally-obtained install to operate and loads certain assets this way.

It’s currently compatible with the vanilla game as well as The Burning Crusade and Wrath of the Lich King expansions. It should be highlighted how much work this project has already involved—with [Kelsi] needing to recreate various functional minutae in the game, from character creation screens to weather systems and skyboxes. There’s still a lot to do, as well, like adding 3D audio support and making it more interoperable with the quest system.

It’s rare that any MMO gets an open-source client, even less so while the original game is still being actively supported by the developers. Still, we do see some creative hacks in this space.

Sorter Uses Cardboard To Organize Card Hoard

January 26, 2019 by 13 Comments

If you collect trading cards of any kind, you know that storage quickly becomes an issue. Just ask [theguymasamato]. He used to be really into trading cards, and got back into it when his kids caught the bug. Now he’s sitting on 10,000+ cards that are largely unorganized except for a few that made it into sleeve pages.  They tried to go through them by hand, but only ended up frustrated and overwhelmed. Then he found out about [Michael Portera]’s Pi-powered LEGO card sorter and got all fired up to build a three-part system that feeds cards in one by one, scans them, and sorts them into one of 22 meticulously-constructed cardboard boxes.

[theguymasamato]’s card sorter is the last stop for a card after the feeder has fed it in from the pile and the scanner has scanned it. The sorter lazy Susans around on a thrust bearing, which is driven by a 3D printed drive wheel attached to a stepper. The stepper is controlled with an Arduino.

Here’s where it gets crazy: the drive wheel and timing belt are made from the flutes of corrugated cardboard. As in, he used that wavy bit in the middle as gear teeth. Every one of those cardboard teeth is fortified with wood glue, a time-consuming process he vows to never repeat. Instead, [theguymasamato] recommends using shims to shore them up as he did in the card feeder. The whole thing was originally going to be made from cardboard. It proved to be too mushy to support the thrust bearing, so [theguymasamato] switched to MDF.

Right now, the sorter is homed via button press, but future plans for the device include an IR break beam switch. We’re excited for the scanner and can’t wait to see the whole system put together. While [theguymasamato] works on that, position yourself past the break to watch the build video.

Hackaday Prize Entry: [Nardax] Shoots Fireballs

March 31, 2017 by 3 Comments

If you’re looking for a high entertainment value per byte of code, [Nardax] has you covered with his wearable spellcasting controller. With not much effort, he has built a very fun looking device, proving what we’ve always known: a little interaction can go a long way.

[Nardax] originally intended his glorified elbow-mount potentiometer to be a fireworks controller. Ironically, he’s now using it to throw virtual fireballs instead. Depending on the angle at which he holds his elbow before releasing it, he can cast different spells in the game World of Warcraft. We’re not at all sure that it helps his gameplay, but we’re absolutely sure that it’s more fun that simply mashing different keys.

There’s a lot of room for expansion here, but the question is how far you push it. Sometimes the simplest ideas are the best. It looks like [Nardax] is enjoying his product-testing research, though, so we’ll keep our eyes out for the next iterations of this project.

We’ve seen a number of high-tech competitors to the good old power glove, and although some are a lot more sophisticated than a potentiometer strapped to the elbow, this project made us smile. Sometimes, it’s not just how much tech you’ve got, but how you use it. After all, a DDS pad is just a collection of switches under a rug.
