The latest entry in the fan favorite franchise Pokémon saw release earlier this month alongside a particularly interesting controller. Known as the Poké Ball Plus, this controller is able to control Pokémon games that are available on completely separate platforms, as well as transfer data between them. It rumbles, It talks, it lights up, it’s wireless, and [Spawn] uploaded a video that reveals what’s really inside.

When it comes to hackers we love, there’s no better example than Jeroen Domburg, a.k.a. Sprite_TM. Sprite’s now working for Espressif, makers of the fantastic ESP8266 and ESP32, where he created a miniature Game Boy and turned this PocketSprite into a real product. He’s installed Linux on a hard drive, and created a Matrix of virtualized Tamagotchis. In short, if you’re looking for someone who’s building the coolest, most technical thing of sometimes questionable utility, you need look no further than Sprite_tm.
Sprite was back at this year’s Superconference, and again he’s bringing out the big guns with awesome hardware hacks. This time, though, Sprite is tapping into his artistic side. Sprite is very accomplished in making PCB art and DaveCAD drawings, but actual art is something that’s been out of reach. No problem, because you can just buy an inkjet printer and make your own art. Sprite’s doing something different, and he’s turning his inkjet into a Magic Paintbrush.
The Hackaday Prize is almost over, and soon we’ll know the winners of the greatest hardware competition on the planet. A few weeks ago, we wrapped up the last challenge in the Hackaday Prize, the Musical Instrument Challenge. This is our challenge to build something that goes beyond traditional music instrumentation. Majenta’s back again looking at the coolest projects in the Musical Instrument Challenge in the Hackaday Prize.
We’re old-school hardware hackers here, and when you think about building your own drum machine, there’s really nothing more impressive than building one out of an Atari 2600. That’s what [John Sutley] did with his Syndrum project. It’s a custom cartridge for an Atari with a fancy ZIF socket. Of course, you need some way to trigger those drum sounds, so [John] is using an Arduino connected to the controller port as a sort-of MIDI-to-Joystick bridge.
If you want more retro consoles turned into musical instruments, look no further than [Aristides]’ DMG-01 Ukulele. It’s a ukulele with a 3D printed neck, bolted onto the original ‘brick’ Game Boy. Yes, it works as a ukulele, but that’s not the cool part. There are electronics inside that sense each individual string and turn it into a distorted chiptune assault on the ears. Just awesome.
How about a unique, new musical instrument? That’s what [Tim] is doing with Stylish!, a wearable music synthesizer. It’s based heavily on a stylophone, but with a few interesting twists. It’s built around an STM32, so there are a lot of options for what this instrument sounds like, and it’s all wrapped up in a beautiful enclosure. It’s some of the best work we’ve seen in this year’s Musical Instrument Challenge.
The Hackaday Prize is almost over, and on Saturday we’ll be announcing the winners at this year’s Hackaday Superconference. Tune in to the live stream to see which project will walk away with the grand prize of $50,000!
We don’t see that many PSP hacks around these parts, perhaps because the system never attained the same sort of generational following that Nintendo’s Game Boy line obtained during its heyday. Which is a shame, as it’s really a rather nice system with plenty of hacking potential. Its big size makes it a bit easier to graft new hardware into, the controls are great, and there’s no shortage of them on the second-hand market.
Hopefully, projects like this incredible “PiSP” from [Drygol] will inspire more hackers to take a second look at Sony’s valiant attempt at dethroning Nintendo as the portable king. With his usual attention to detail, he managed to replace the PSP’s original internals with a Pi Zero running RetroPie, while keeping the outside of the system looking almost perfectly stock. It wasn’t exactly a walk in the park, but we’d say the end definitely justifies the means.
The first half of the project was relatively painless. [Drygol] stripped out all the original internals and installed a new LCD which fit so well it looks like the thing was made for the PSP. He then added a USB Li-ion charger board (complete with “light pipe” made out of 3D printer filament), and an audio board to get sound out of the usually mute Pi Zero. He had some problems getting everything to fit inside of the case. The solution was using flat lithium batteries from an old Nokia cell phone to slim things down just enough to close up the PSP’s case with some magnets.
What ended up being the hardest part of the build was getting the original controls working. [Dyrgol] wanted to use the original ZIF connector on the PSP’s motherboard so he wouldn’t have to modify the stock ribbon cable. But it was one of those things that was easier said than done. Cutting out the section of PCB with the connector on it was no problem, but it took a steady hand and a USB microscope to solder all the wires to its traces. But the end result is definitely a nice touch and makes for a cleaner installation.
We’ve covered the exciting world of PSP homebrew, and even DIY batteries built to address the lack of original hardware, but it’s been fairly quiet for the last few years. Here’s hoping this isn’t the last we’ve seen of Sony’s slick handheld on these pages.

One of the great joys of owning a 3D printer is being able to print custom cases for boards like the Raspberry Pi. What’s more, if you are using a desktop PC, you probably don’t have as many PCI cards in it as you used to. Everything’s moved to the motherboard. [Sneekystick] was using a Pi with a PC and decided the PC itself would make a great Pi case. He designed a bracket and it looks handy.
The bracket just holds the board in place. It doesn’t connect to the PC. The audio, HDMI, and power jacks face out for access. It would be tempting and possible to power the board from the PC supply, but to do that you have to be careful. Connecting the GPIO pins to 5V will work, but bypasses the input protection circuitry. We’ve read that you can find solder points near the USB plug and connect there, but if you do, you should block out the USB port. It might be nice to fill in that hole in the bracket if you planned to do that.

Chiptunes are cool, but when you get into it, you realize you’re mostly dealing with Commodore SID tunes, Atari POKEY tracks for the cool kids, bleeps and bloops from a Game Boy, and maybe some NES tracks thrown in for good measure. There’s another option out there – the sound chip in the Sega Genesis. This thing could do drums, man, and [Aidan Lawrence] built the perfect player for the tuneful silicon tucked inside the classic 16-bit console.
[Aidan] had previously built a tiny little music player based on the YM3812 chip, the Yamaha chip found in SoundBlaster and Adlib sound cards. The chip inside the Sega Genesis, the Yamaha YM2612, is a bit different. The killer feature of this chip, PCM waveforms, aren’t stored as simple, small bits of code. These are massive blobs of binary data sent to the chip’s DAC. The SEGGGGAAAA intro of Sonic the Hedgehog, for example, used an eighth of the the cartridge space. You’re not going to build a Sega chiptune player with a tiny little microcontroller and 20kB of RAM.
The solution came in the form of an external SPI RAM device. The 23LC1024 is a full 1 Megabit in size, and since it’s SPI, it’s more than fast enough to keep up with the sample speed. The rest of the circuit including the mixer, preamp and power amp are based on the Genesis’ actual schematics, with an SD card and OLED thrown in for good measure. How does it sound? There’s a great video below the break and yes, the soundtrack from Sonic 3 sounds just as good as it did twenty years ago.
When home consoles go mobile, whether in the form of modded original hardware or emulation, they usually take a pretty standard shape. A screen in the middle, with buttons either on the sides or below it. Basically the same layout Nintendo popularized with born-handheld systems such as the Game & Watch series and original Game Boy. Like the saying goes, if it ain’t broke…
But [Le Nerdarto] had a different idea. He came across a broken N64 and wanted to turn it into a portable console, but not necessarily a handheld one. Noticing the cartridge was about the perfect size to contain a small LCD and in an ideal position, he set out to make what is arguably the most literal interpretation of “portable N64” we’ve ever seen. It might not be the most practical iteration of this concept, but it definitely gets extra points for style.
After he stripped the N64 of its original hardware, he installed a Raspberry Pi 3 and an RC battery eliminator circuit (BEC) to get 5V out of the internal 6200 mAh 7.4V battery. [Le Nerdarto] says this provides power for the Pi, the LCD, and the various lighting systems for up to 10 hours. He’s also added USB ports in the front of the system for controllers, and an HDMI port on the back so he can still connect the system up to a TV when not on the move.
The 3.5 inch LCD in the cartridge is arguably the centerpiece of the build, and while it might be on the small side, we can’t deny it’s a clever idea. [Le Nerdarto] had the good sense to tilt the it back a few degrees to put the display at a more comfortable angle, but otherwise it looks stock since he was able to fit everything in without cutting the back of his donor cartridge out. For those who might be wondering, the “cartridge” can’t be removed, but we’ll admit that would have been a killer feature to add especially with the HDMI port on the back.
Of course, since it’s running emulators on a Raspberry Pi, this isn’t only a portable N64. The front mounted USB ports allow him to plug in all sorts of controllers and emulate classics from pretty much any console that’s older than the N64 itself. Ironically the Raspberry Pi 3 isn’t exactly an ideal choice for N64 emulation, but a good chunk of titles are at least playable.
If you’re more of a purist and want a true portable N64, we’ve covered plenty of those over the years to get you inspired.
