  • My new 3 string instrument

    I haven’t updated my blog in a very long time, so I will change that today with a new post about my new 3 string instrument. This is a cross between an Appalachian dulcimer (strum stick), Guitar, Ukulele, Balalaika, and a few other musical instruments. It is roughly the size of a soprano ukulele. This […]

  • Version 3.0 is now done

    Hello again. I have finished 3.0 of my handheld project. I added a SD card reader that functions as a ‘cartridge’ reader and made the left action button larger to give it a more distinct look. This project has no name and I want one. I will take any non-offensive name suggestion and might have […]

  • A new Pi Powered handheld with a crank

    Hello again. Its been a month since I last posted. I’ve been busy with life, but now, I’m working on a project that has been put on the back burner. It is a Pi Zero handheld with a crank on the side, similar to another popular console called the Playdate. Presenting the Playdave (name pending, […]

  • Project updates

    I made a 2 button version of my Pico 8 fanmade handheld. It works better than the 4 button version so I’ll focus more on just the 2 button version. Cartridges I also made it possible to boot into Pico 8 using cartridges. They aren’t rom cartridges, but SD cards with a 3D printable shell […]

  • A Larger Screen and 2 buttons

    Most people who have tried my handheld or seen pictures of it online have complained about the screen being too small. I like the way the screen looks, but I have to agree with them. The display is a 128×128 OLED display from Waveshare. It works great, but I tried finding a larger 128×128 screen […]

  • Version 1.0 has arrived

    I’ve reached version 1.0. These pictures aren’t from version 1, but I made some last-minute changes. The power switch on the top of the console needs some hot glue to hold it in place better, but other than that, it is done. Features: Raspberry Pi Zero W – The computer that powers Pico 8. Waveshare […]

  • Performance issues fixed and plan B

    I am realizing that AA batteries are a wasteful solution and that the battery holder is causing the screen to freeze randomly, so I’m switching over to rechargeable batteries using a Adafruit Powerboost 1000C. I don’t see a short and there aren’t any bridged connections causing a short. When I plugged in the Pi Zero […]

  • My Pico 8 fanmade handheld

    Project background Hello, I’m grhmhome and this is my first soldering project from scratch. I’m teaching myself how to solder and wanted to do more projects so I could learn more. I’m a fan of retro-gaming and enjoy the Pico 8 platform. What is Pico 8? It is software that replicates the look and feel […]

  • Soldering fun

    I finally finished soldering the buttons. It was my first time soldering a perfboard. I had a few issues though. First, I had to reposition a tactile button then I had to replace one of the buttons because Retropie wouldn’t recognize the button and then I replaced a jumper cable. Now the buttons all work. […]
