A few months back, frequent DI contributor Nick Cornford showed us some clever circuits using the TDA7052A audio amplifier as a power oscillator. His designs also demonstrate the utility of the 7052’s nifty DC antilog gain control input: ...

The versatility of the venerable LMC555 CMOS analog timer is so well known it’s virtually a cliche, but sometimes it can still surprise us. The circuit in Figure 1 is an example. In it a single linear pot in a simple RC network sets the ...

Digital omnipolar magnetic switch in LGA4 package LF21173TMR is a digital omnipolar magnetic switch that integrates TMR and CMOS technology in order to provide high precision, low current consumption at 160nA and 10 Gauss typical operational ...

Particulate matter (PM2.5) monitoring is a key public-health metric. Vehicle- and drone-mounted sensors can expand coverage, but many existing systems are too costly for broad deployment. This Design Idea (DI) presents a prototype PM2.5 sensing and ...

Low Power Particle Sensor PM2105L is a laser particle sensor module for indoor use based on laser scattering technology. This sensor can measure particle concentration size between 0.3um~10um exactly and output particle mass concentration PM1.0, ...

A cost-effective RISC-V MCU with Wi-Fi and Bluetooth 5 (LE) connectivity for secure IoT applications in QFN32 (5×5 mm) package ESP32-C3 is a single-core Wi-Fi and Bluetooth 5 (LE) microcontroller SoC, based on the open-source RISC-V ...
