There’s also a DS1307 real time clock module to keep precision time and a push button for “manual” feeding. used ’s fish feeder as the base, upgrading it with a better servo, adding a Raspberry Pi Zero W along with software for the Pi and an Android application to control the schedule of feedings. ![]() writes that the system can dispense about 0.9 g/s and that it’s designed for granulated food, as flakes have problems because “their low density and large surface area tend to get them stuck in the throat of the hopper” - an issue that we’ve looked into previously. ![]() The screw conveyor is driven by a Feetech FS5106R servo which provides enough force to overcome jamming that might occur with pellets getting stuck in the conveyor system. The mechanics of the fish feeder include a screw conveyor system that pushes the food pellets fed from a food store basin. To help with alleviate the mundane aspects of daily life, has created an automatic fish feeder, complete with 3D print files, firmware, and an Android app for complete control over scheduling and feeding.

When the snake tightened around the salamander’s head, the hellbender tried to reposition its bite, giving the northern water snake the chance to escape. The scene was unexpected, as hellbenders tend to hunt for smaller prey. Herasimtschuk says that if you patiently linger around these two-foot long salamanders, they’ll eventually interact with you and “accept you into their world.” That’s how he captured what may be the only photograph of a hellbender attempting to eat a snake, which earned Herasimtschuk a Wildlife Photographer of the Year award from the Natural History Museum in London. Southern Appalachia is also home to Herasimtschuk’s favorite amphibian: the hellbender, a giant aquatic salamander native to North America. The region sustains roughly 300 to 400 native species of fish. Several places that Herasimtschuk has photographed, such as southern Appalachia, harbor some of the most diverse freshwater ecosystems in the world. “You're essentially exposing people to a whole new world, but it's a world that a lot of times is right in their own backyard.” UNIQUE BEHAVIORS “People know more about a clown fish in the coral reef than a minnow that lives 10 minutes from their house,” Herasimtschuk says. Despite the critical role they play for both humans and in nature, they’re often overlooked. They control flooding they provide irrigation for crops they’re harnessed for hydropower. Rivers are also primary sources of drinking water for humans. These environments not only are habitats for a range of aquatic plants and animals, but they support a whole web of terrestrial wildlife too, from the birds that nest in riparian areas or stop over on migrations to animals like beavers that use rivers for travel to predators who eat river-dwelling creatures. For almost a decade, he’s worked with Freshwaters Illustrated to document creek and river life across North America, from the mountains of Colorado to El Yunque National Forest in Puerto Rico. ![]() Herasimtschuk is the photographer and cinematographer for Freshwaters Illustrated, an Oregon-based nonprofit that seeks to educate the public about freshwater ecosystems and inspire people to protect them. ![]() “There's all this life that's disappearing, and nobody even knows it’s there,” Herasimtschuk says. Photograph by David Herasimtschuk, Freshwaters Illustrated They are listed as vulnerable to extinction, and some localized populations have disappeared entirely.
