OpenMacroRail: controlling a motorized macro rail #Photography #ESP32 @AppliedProc
Applied Procrastination has designed an open source PCB-design for controlling a motorized photography macro rail. Designed for photographers with electronics skills rather than engineers with photography skills.
Main features:
Zero surface mount components, and should therefore be possible to hand solder – even for people with novice soldering skills.
Flexible solution for connecting to most types of camera via 2.5mm stereo jack, pin header, or solder joints.
Simple design for driving a single motor via a BTT TMC2209 V1.2 motor driver.
Based on the WiFi-enabled NodeMCU 32S V2 DevKit.
Has broken out headers for connecting limit switches and rotary encoders (neither of which are used in the intended application the board was designed for).
Total cost of around $30 (Camera, optics, motor, slider, and tools not included)
The OpenMacroRail Firmware provides a web-interface for accurately moving a camera in small increments in order to do focus stacking.
ALl the details and design files are on GitHub. Software is also on GitHub.

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.
