This fish is driving its own motorized aquarium

by Larra Morris

It’s always a good idea to give your pets lots of exercise and freedom. But how does that work with a fish who are reliant on a tank full of water to live? That’s easy; you just strap its aquarium to an RC car and rig up a device that lets the fish steer.

Sound crazy? Of course it does, but that’s what makes this hack so great. And you might be wondering how the folks at Studio Diip taught this goldfish to manipulate a tiny steering wheel. But that’s not how they did it. Instead, a webcam perched above the tank tracks the fish’s position, and whichever side it swims to is the direction the RC car goes.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
