Blastoise Humidifier Shows Us You Don’t Need A 3D Printer If You’re This Good With A 3D Pen

January 17, 2024 by Lewin Day 14 Comments

[3D SANAGO] is a bit of a master when it comes to using a 3D-printing pen. Their latest work involved fixing a broken humidifier and giving it a Pokemon-themed makeover. It’s an education in just what can be achieved with a tool many of us write off as a simple novelty.

The basic idea of the build was to create a Blastoise figurine that serves as a humidifier. Work starts with marking out a basic outline on a round stone. The 3D pen is then used to create a tortoise shell with the appropriate concave shape, directly on the rock. [3D SANAGO] also demonstrates how a simple plastic framework can be heated with a blowtorch and shaped around the rock as needed to generate gentle curves. Meanwhile, a simple marker pen serves as a form for creating the gun barrels on Blastoise’s back. The legs are built with a similar technique, but with expert manipulation with a blowtorch to turn them into stubby muscular forms.

The full figurine is built up in stages, with individual wireframe components assembled into a complete body. The gaps in the frame are then filled in by hand, which takes a long time; [3D SANAGO] calls it “the most boring for sure.” Plenty of post-processing is then done with various sanding tools and a bladed tip on a soldering iron. The latter is used as the melting action allows the creation of a smooth final surface. In contrast, subtractive methods like sanding would leave holes and divots that need to be filled in before painting. There’s plenty of sealing to be done before paint, too, to ensure the interior of Blastoise can hold water without leaking. Then, the internal componets are installed and the body finished to its final cartoon form. In case you’re wondering, [3D SANAGO] says that sanding took 2-3 days to get such a great result.

If you really dig it, it’s on display at [3D SANAGO’s] cafe in Daejeon. Overall, it’s amazing to see such craftsmanship with a 3D pen. A resin printer could obviously print a wonderful Blastoise of similar quality, but there’s something about watching the level of human skill in this that’s just compelling. Video after the break.

Pokemon ROM Hacks Brought To The Real World

February 27, 2023 by Bryan Cockfield 4 Comments

If you were a kid anywhere in the last 30 years, it was nearly impossible to avoid at least some exposure to the Pokemon franchise. Whether that’s through games like Red and Blue to Scarlet and Violet, the brief summer everyone played Pokemon Go, or to other media such as the trading card game or anime, it seems to have transcended generations and cultures fairly thoroughly. And, if you’ve consumed all there is of official Pokemon video gaming, you may be surprised to know there are a number of slightly modified games floating around out there that can be translated onto game carts just like their official counterparts.

[imablisy] has played a lot of these ROM hack games but always within something like a virtual console or emulator, so he wanted something physical which would work on original hardware of the era. For this he’s making physical copies of Flora Sky and Vega, which are based on Pokemon Emerald and Fire Red originally for the Game Boy Advance. To get the cart he found a bunch of Mother 3 cartridges to use as the donor. From there he backed up his Emerald and Fire Red cartridges, modified the ROMs with the modifications, and then sent those new ROMs to overwrite the data on the Mother 3 cartridges.

A playable cartridge is only half of the build, though. He wants these to look and feel like real Pokemon games, so he added a color-appropriate translucent case and also printed custom holographic labels for each. It might seem straightforward, but from the style of [imablisy]’s video it’s clear he is very familiar with processes like these, from the artwork all the way to the hardware and software side. We’re also pleased no classic hardware was damaged during this build, much like this version of Doom on an NES cart which used a common game for the donor to upset the least number of collectors.

Hackaday Links: January 29, 2023

January 29, 2023 by Dan Maloney 22 Comments

We’ve been told for ages that “the robots are coming for our jobs!” It’s true that we’ve seen robots capable of everything from burger flipping to bricklaying being demonstrated, and that’s certainly alarming for anyone employed in such trades. But now it looks like AI has set its sights set on the white-collar world, with the announcement that ChatGPT has managed a passing grade on a Wharton MBA exam.

For those not in the know, the University of Pennsylvania’s Wharton School of Business is in the major league of business schools; earning a Master’s in Business Administration from that august institution is no mean feat, and is likely to put the budding executive on a ballistic career trajectory. So the fact that ChatGPT could pass the exam is significant. But before you worry about a world in which our best and brightest business leaders are replaced with soulless automatons, relax. The exam presented to ChatGPT was just a final exam for one course, Operations Management, so it’s not like it aced everything an MBA is expected to know, and it took a lot of hints from a human helper to get it that far. It’s also reported that it made a lot of simple math mistakes, too, so maybe a Wharton MBA isn’t that much of a big deal after all.

Robot Gets A Life-Sized Pokemon Costume For Halloween

November 12, 2022 by Lewin Day 3 Comments

Quadruped robots are everywhere now that companies like Boston Dynamics are shipping smaller models in big numbers. [Dave’s Armoury] had one such robot, and wanted to give it a Pokemon Halloween costume. Thus, the robot dog got a Jolteon costume that truly looks fantastic. (Video, embedded below.)

You would think that covering a quadruped robot in foam would ruin it, but somehow it didn’t stop it moving too badly at all.

The robot in question is a Unitree Go1, which [Dave] had on loan from InDro robotics. Thus, the costume couldn’t damage or majorly alter the robot in any way. Jolteon was chosen from the original 150 Pokemon as it had the right proportions to suit the robot, and its electric theme fitted [Dave’s] YouTube channel.

A 3D model of Jolteon was sourced online and modified to create a printable head for the robot application. Two 3D printers and 200 hours of printing time later, and [Dave] had all the parts he needed. Plenty of CA glue was used to join all the parts together with some finishing required to make sure seams and edges didn’t spoil the finish too much. Wood filler and spray paint were used to get the costume looking just like the real Pokemon. Continue reading “Robot Gets A Life-Sized Pokemon Costume For Halloween” →

Taking Pokémon On A Walk

November 9, 2022 by Bryan Cockfield 7 Comments

Emulating old computers or video game systems isn’t always about recreating childhood nostalgia or playing classics on hardware that doesn’t exist anymore. A lot of the time it can be an excellent way to learn about the mechanics of programming a video game. Plenty of older titles have available source code that anyone can pour over and modify, and one of those is Pokémon Emerald. This was the first Pokémon game that [Inkbox] played, and he added a few modern features to it with this custom ROM file.

The first thing to add to this game was the ability to have one’s Pokémon follow their character around in the overworld map. This is common in later games, but wasn’t yet a feature when Emerald and Ruby first came out. [Inkbox] needed to import sprites from later games into the Emerald game file, convert their color palettes to match the game’s palette, and then get to work on the mechanics. After everything was finished, the Pokémon not only follow the player around the map but are animated, enter and exit their Pokéballs, and even jump off ledges in a believable, 32-bit way.

One of the great things about older games like these is that they’ve been around long enough to have source code or decompiled code available, they often have plenty of documentation, and the platforms they operate on are well-known by now as well. Pokémon Emerald is not alone in this regard; in fact, there is a huge Game Boy Advance homebrew scene that is not too difficult to get involved in.

Building A Poketch Powered By An Apple Watch

October 2, 2022 by Lewin Day 2 Comments

In Pokemon Diamond and Pearl and the ensuing modern re-releases, the player is given a computer called a Poketch to assist on their journey. [DistressedOwl] decided to build one for real.

The build starts with an Apple Watch, which provides a capable smartwatch platform and a quality display. It’s then given a snap-on case that’s 3D printed in PLA. [DistressedOwl] decided to use model painting techniques to give the build a worn-in, distressed look, which feels fitting for a watch belonging to a rough-and-tumble Pokemon trainer.

The Apple Watch runs a custom app via Test Flight which mimics the appearance of the in-game Poketch. It includes various screens like a basic map and Pikachu looking melancholy next to a digital watch. Sadly, the dowsing app in the Poketch won’t help you find hidden items on the ground.

It’s a build that reminds us of some great Pip-Boy builds over the years. It would make the perfect addition to a Pokemon cosplay, too. Just don’t forget to take some Pokeballs along too!

A Pokemon Silver Cartridge Made Of Pure Silver

September 16, 2022 by Lewin Day 51 Comments

The big problem with Pokemon Silver is that it came in a cartridge made of only-slightly-sparkly grey plastic. [Modified] decided to fix all that, making an all-silver cartridge instead.

The cartridge was first modeled to match the original as closely as possible, and 3D printed for a fit check. From there, a test cartridge was machined out of a block of aluminium to verify everything was correct. It’s a wise step, given the build relies on a 1-kilogram bar of silver worth roughly $750.

With everything checked and double-checked, machining the silver could go ahead. Every scrap of silver that could be saved from the CNC machining was captured in a box so that it could be recycled. Approximately 28 grams of silver was lost during the process. WD40 was used as a coolant during the machining process, as without it, the silver didn’t machine cleanly. The final cart weighed 164 grams.

It’s not a particularly hard project for an experienced CNC operator, but it is an expensive one. Primary expenses are the cost of the silver bar and the Pokemon cart itself, which can be had for around $50 on the usual auction sites.

However, the “heft and shine” of the finished product is unarguably glorious. Imagine handing that over to a friend to plug into their Game Boy! Just don’t forget to ask for it back. If you’re rich enough to do the same thing with Pokemon Gold or Platinum, don’t hesitate to drop us a line.

We love a good casemod, and this one reminds us of a brilliant crystal PlayStation 2 from years past.
