Fish Hammer actuation device? They’re a dime a dozen these days! We jest, of course. This build and documentation from instructables suer Neil Mendoza is smashing, to say the least.
This Instructable will show you, in detail, how to construct a track-based curvilinear motion system. These systems are the most common type of drive mechanism for fish hammers (the part that makes the hammer move around the aquarium). However, the same mechanism can be employed to move anything along a curved track. For example, a motion control system for cameras.
If you do decide that you want to actuate a fish controlled hammer rather than any other object, below is an overview of some of the things that you might need to consider…

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.
