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).

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.
