Narrowband RF Power Amplifier (520MHz)
https://www.electronics-lab.com/narrowband-rf-power-amplifier-520mhz/
The RF power amplifier stage is usually the final active block of any electronic system that is transmitting RF power. Relatively low power RF signals are amplified to produce a more powerful signal in order to be transmitted over greater distance. RF output power can range from a few mW to MW, depend by application.

LDO regulator is qualified for automotive designs
https://www.electronics-lab.com/ldo-regulator-is-qualified-for-automotive-designs/
by Susan Nordyk @ edn.com: Housed in a tiny 2×2-mm, 6-pin DFN package, the MAQ5300 voltage regulator from Micrel boasts a dropout of only 100 mV at 300 mA. The AEC-Q100-qualified part is suitable for space-constrained and high-reliability applications that are subjected to the harsh environments and temperatures commonly encountered in automotive and industrial applications. The […]
ESP8266 MQTT battery monitor project
https://www.electronics-lab.com/esp8266-mqtt-battery-monitor-project/
Steve’s latest project, a wireless MQTT battery monitor: This board uses an ESP8266 (ESP12), a Texas Instruments INA226 I2C voltage and current monitor, and a Texas Instruments LMR12010X buck converter. This board is designed to wirelessly monitor 12 volt batteries and power supplies using an external current shunt resistor. The voltage across the shunt resistor […]

Armadillo 43T integrates a 4.3″ TFT display, resistive touch panel and a single board computer with Linux OS into one compact unit. Armadillo 43T is suitable for everyone, who needs a complete microcomputer with a display – “all in one solution”. Armadillo 43T is driven by operating system Armadillian designed in a way to optimally […]
Distance Measurement using Infrared Sensor with ADC0804 & 8051 Microcontroller
https://www.electronics-lab.com/distance-measurement-using-infrared-sensor-with-adc0804-8051-microcontroller/
This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact distance is also calculated and displayed on a 16×2 LCD interfaced to the microcontroller. The IR receiver detects the IR radiations reflected by the object being measured. […]
Raspberry Pi OLED Internet Bandwidth Display
https://www.electronics-lab.com/raspberry-pi-oled-internet-bandwidth-display/
by Archie500 @ instructables.com: In a very brief summary it works as follows: The Raspberry Pi uses SNMP (Simple Network Management Protocol) to get the WAN data rates from the router and then displays these graphically on the OLED screen. The Raspberry Pi was already set up as our media player and is next to the […]
Energy Harvesting Circuit
https://www.electronics-lab.com/energy-harvesting-circuit/
by hackarobot.com: Recently, I built an energy harvesting circuit based on an ultra low voltage DC/DC step up converter chip (LTC3108) from Linear Technology. With a 1:100 coil transformer (CoilCraft LPR6235), it converts the tiny voltage generated from Peltier thermo-electric generator into high enough level to drive small circuits.
