It looks like a cute little dolphin-themed toy, but the Flipper Zero is a surprisingly powerful learning tool for hacking. Here's how I mastered mine—and how you can, too.

There was a time when only the richest ham radio operators could have a radio with a panadapter. Back in the day, this was basically a spectrum analyzer that monitored a broad slice of the ...

Switch-mode power supplies (SMPS) based on the boost principle can convert a low voltage into a higher voltage. For this purpose, the standard boost topology is used as shown in Figure 1. 1. A simple ...

Abstract: Neuromorphic hardware using nonvolatile analog synaptic devices provides promising advantages of reducing energy and time consumption for performing large-scale vector-matrix multiplication ...

Car key batteries typically last 2-5 years, but they can drain prematurely due to temperature. Use a voltmeter to check the voltage accurately to avoid situations where the car suddenly stops ...

Gen Zers are trying to get over their phone addiction with the help of products that make it harder to impulsively doomscroll, while also allowing them to not throw their phone away entirely. Among ...

Abstract: Over-the-Air aggregation (OTA) is a promising technology for Internet-of-Things (IoT) applications, but it can be vulnerable to burst interference from co-channel non-cooperative IoT ...

In this video, I take a multimeter and show you how to use various functions on the multimeter on how to test a few different things, showing continuity, resistance, voltage, and amperage. Donald ...
