Chromium(III) Telluride (Cr2Te3) is an interesting material for (ferro)magnetic applications, with Yao Wen and colleagues reporting in a 2020 Nano Letters paper that they confirmed it to show spontaneous magnetization …read more Continue reading Chromium(III) Telluride As Ferromagnetic Material With Tunable Anomalous Hall Effect

TMD-3: Clever Hall Sensor Hack Leads to Better Turing Demo

We’ll beat everyone to the punch: yes, actually building a working Turing machine, especially one that uses a Raspberry Pi, is probably something that would have pushed [Allen Turing]’s buttons, …read more Continue reading TMD-3: Clever Hall Sensor Hack Leads to Better Turing Demo

Hall Sensors Offer Drop-In Replacement for Drifting Game Console Joysticks

No bananas were harmed in the making of this Hall effect drift-proof joystick replacement. OK, not really — two bananas were turned to mush. But it’s OK, they’re just bananas, …read more Continue reading Hall Sensors Offer Drop-In Replacement for Drifting Game Console Joysticks

Exploring the Hall Effect for Haptic Feedback PS4 Joysticks

Modern gaming console controllers aren’t without their annoyances — Joy-Con drift, anyone? The problems might stem from design deficiencies, but we suspect that user enthusiasm and the mechanical stress it …read more Continue reading Exploring the Hall Effect for Haptic Feedback PS4 Joysticks

Mercury Thrusters: A Worldwide Disaster Averted Just In Time

The field of space vehicle design is obsessed with efficiency by necessity. The cost to do anything in space is astronomical, and also heavily tied to launch weight. Thus, any …read more Continue reading Mercury Thrusters: A Worldwide Disaster Averted Just In Time

One Stepper Plus a Whole Bunch of Magnets Equals a Unique Seven-Segment Display

Sometimes the cost of simplicity is extra complexity. It seems counterintuitive, but it seems to be true. And this single-motor mechanical seven-segment display seems to be a perfect example of …read more Continue reading One Stepper Plus a Whole Bunch of Magnets Equals a Unique Seven-Segment Display
