Getting Started

Adafruit Playground is a wonderful and safe place to share your interests with Adafruit's vibrant community of makers and doers. Have a cool project you are working on? Have a bit of code that you think others will find useful? Want to show off your electronics workbench? You have come to the right place.

The goal of Adafruit Playground is to make it as simple as possible to share your work. On the Adafruit Playground users can create Notes. A note is a single-page space where you can document your topic using Adafruit's easy-to-use editor. Notes are like Guides on the Adafruit Learning System but guides are high-fidelity content curated and maintained by Adafuit. Notes are whatever you want them to be. Have fun and be kind.

    How To 3D Print Models from The Met

    Tools Needed

    In this article from This Is Colossal, dozens of scanned objects from The Metropolitan Museum of Art are available to see. The page on The Mets website shows a decent list of artifacts that can be viewed in 3D in your browser. They feature high-resolution models with textures and even QR codes to scan for viewing in AR on mobile phones. 

    This got us thinking, if there's a model, we should be able to 3D print them, right?

    How to Repair Maschine Mikro Mk3 Pads

    Non-responsive Pads

    Repairing Native Instruments Maschine Mikro MK3 pads involved opening the enclosure to clean the contact traces on the PCB, sensor pad and rubber elastomers with isopropyl alcohol and a Q-tip to remove debris (mostly cat hair).

    This playground note will walk through the device teardown and cleaning the contacts and rubber elastomer pads.

    Remove Bottom Panel screws

    Start flipping the device over with the bottom panel facing up. Then, use a Phillips screwdriver to remove 14 screws from the bottom panel.

    Displaying Images on Pico Mac Emulator for Fruit Jam

    With my recent retro mac classic inspired enclosure project for the Fruit Jam, I got the crazy idea to display my own images on the mac emulator. Sure, you can run MacPaint, but wouldn't it be cool to display custom graphics like the Fruit Jam logo? Well, it turns out there's a bit of a process to get images to display on System 7.5, specifically on 68K architecture (which is what the pico-mac emulator is based on).

    Image File Formats

    JPEG, PNG and GIF images are the norm with modem day computers. But, in 1984, these image formats were not yet a thing. I thought, surely displaying a bitmap image on Mac OS System 7 shouldn't be too hard, right?

    After searching google, easiest approach seemed to be: Use the Graphic Converter mac app to convert a JPEG into a MacPaint document. This however, didn't quite seem to work. When I import the converted macpaint image file into Mini vMac, it wouldn't open in MacPaint. Weird, Ok, lets try a native image file format. Again, that's not really a thing. Enter the world of the .PICT (QuickDraw picture).

    3D Hangouts This Week

    Just finished live streaming this week. We highlighted last week's learn guide, Talking D20, and showed off clear resin parts (Thanks to PhilB!). Pedro showed off his Dual-Extruded D20 and mentioned the STLs for 3D printers with multi-material capabilities. 

    For the prototyping segment, Pedro show his foam-core Tombstone and a 64x32 RGB Matrix. It'll use the matrix FeatherWing and PropMaker RP2040 Feather. Feature wise, it'll have text and graphics displayed on the matrix with accompanying sound FX and a servo-controlled crow triggered with a TOF sensor. Liz Clark will be collaborating with him to write the code in CircuitPython.

    I'm working on a synth guitar using PropMaker RP2040 Feather with two 1x4 NeoKey QT boards, rotary QT encoders, speaker, switches and a strum mechanism. Liz will also be collaborating with me on the code, which will be done in CircuitPython using the SynthIO library.

    For this week's Timelpase Tueday segment, we were both surprised with the tBulb product from toolmoon. It's a really neat USB powered lightbulb that is meant for attaching to a 3D printed base. Their thingiverse profile has tons of in-house designs that look amazing! Their product is also available to purchase on amazon.

    Community makes this week was mostly props, which always fun to see!
