Flygonial shared this project on Thingiverse!

PSA: Rektify Mk.2 is currently being printed out and prototyped as you read, if you can wait a few weeks, I’ll have a better executed design than this out in almost every way.

Rektify is a sophomorically named full-auto foam dart blaster. It is compatible with 130 to 180 sized DC brushed motors (possibly only 130 as a pusher though it may fit without a voltmeter), and accepts most magazines compatible with Hasbro Nerf blasters (compatibility with Buzz Bee mags is not guaranteed). Additional design features include a horizontal flywheel cage, 14mm bore, flat-top with a full-length of picatinny rail, and top-loadability. It accepts full sized or submini microswitches for its flywheel and pusher switches, but only submini sized ones for its cycle control switch.

Optional additions include: Voltmeter mount, kill switch mount, an internal battery tray (89x52x20mm), a stock mount that doubles as a tray door, and an entire printable stock that includes a significantly larger battery tray (125x50x30mm). The scotch yoke pusher can either be one with a dwell or a simple straight slotted yoke (former may result in more reliable cycle control, latter is easier on the gearbox). Cage options now include 41.5mm, 43mm spacing, Eclipse, with optional dart guides, and 14 and 16mm bores for non-Eclipse cages (former for better precision, latter for more reliability especially with top-loading).

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
