🚁🧠 Ah yes, the thrilling world of drone physics, where you too can transform your weekend hobby into an endless maze of equations and jargon! 🤓✨ Perfect for those who've always dreamed of mixing #calculus with their drone flying, because who wouldn't want to spend their free time reconciling inertial frames? 📉😂

Measuring the characteristics of some cheap J113 / 2SJ113 n-channel JFETs I bought, so I can match them / divvy them into bins.
Put #15 of 20 into the JFET test circuit, and the power supply's current limiter kicks in ... whoops. Did I have it turned around so I swapped the terminals? Nope...
Take a peek at it. Slightly different marking. Still "J113", but the factory/date code is different. Put it in the component tester... it's a PNP BJT transistor, not a JFET at all, and with a pinout completely unsuitable for the JFET test circuit. If it had been in for more than a second, it probably would have let the Magic Smoke out.
Oh, #AliExpress sellers, where would #hobbyist #electronics people be without you? Somewhere with less excitement in their lives, I guess.
