Supports multiple power inputs: PD 3.1/3.0/2.0, QC 3.0/2.0, (5-28 V DC), LiPo batteries, and power adapters.
The HT140 combines hot tweezers and a soldering iron, with independent single- or dual-sided heating. Use it as a soldering iron with a tip, or as hot tweezers for easy SMD desoldering.
Voltage and current can be adjusted based on the power source.
Features dual temperature control, presets, quick temperature increase, and fine-tuning.
128 x 32 OLED screen with adjustable brightness, and orientation. Switchable °C/°F.
High-precision heating element with ±1% accuracy. Melts solder in just 2 seconds.
Smart standby, sleep, and wake-up functions extend tip lifespan and boost efficiency.
Supports temperature calibration and compensation for precise work.

Die Hochfrequenztechnik ist eines der Gebiete, auf denen man auch heute noch eigene Ideen in die Tat umsetzen kann. Unzählige Schaltungsvarianten mit besonderen Zielsetzungen geben Raum für sinnvolle Experimente und Projekte. Vieles kann man nicht einfach kaufen. Detektorradios ohne eigene Energiequelle, einfache Röhrenempfänger mit einem Hauch von Nostalgie, die ersten Empfangsversuche mit dem Software Defined Radio oder Spezialempfänger für den Amateurfunk, all dies lässt sich mit wenig Aufwand realisieren.
Lange Zeit war das Radiobasteln der Einstieg in die Elektronik. Inzwischen gibt es auch andere Wege, vor allem über Computer, Mikrocontroller und die Digitaltechnik. Allerdings kommen die analogen Wurzeln der Elektronik oft zu kurz. Die Radiotechnik eignet sich besonders gut als Lernfeld der Elektronik, weil man hier mit den einfachsten Grundlagen beginnen kann. Aber auch die Verbindung zur modernen Digitaltechnik liegt auf der Hand, wenn es z. B. um moderne Abstimmverfahren wie PLL und DDS oder um moderne DSP-Radios geht.
Dieses Buch gibt einen Überblick und stellt eine Sammlung einfacher Projekte vor. Der Autor möchte Sie dabei unterstützen, eigene Ideen zu entwickeln, eigene Empfänger zu entwerfen und sie zu erproben.
This complete ESP32 microcontroller programming course features a textbook, a component kit, hands-on projects, and a comprehensive online course with simulations. It is ideal for step-by-step learning of embedded systems programming with Arduino using a practical, hands-on approach.

For Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr
Bluetooth Low Energy (BLE) radio chips are ubiquitous from Raspberry Pi to light bulbs. BLE is an elaborate technology with a comprehensive specification, but the basics are quite accessible.
A progressive and systematic approach will lead you far in mastering this wireless communication technique, which is essential for working in low power scenarios.
In this book, you’ll learn how to:
Discover BLE devices in the neighborhood by listening to their advertisements.
Create your own BLE devices advertising data.
Connect to BLE devices such as heart rate monitors and proximity reporters.
Create secure connections to BLE devices with encryption and authentication.
Understand BLE service and profile specifications and implement them.
Reverse engineer a BLE device with a proprietary implementation and control it with your own software.
Make your BLE devices use as little power as possible.
This book shows you the ropes of BLE programming with Python and the Bleak library on a Raspberry Pi or PC, with C++ and NimBLE-Arduino on Espressif’s ESP32 development boards, and with C on one of the development boards supported by the Zephyr real-time operating system, such as Nordic Semiconductor's nRF52 boards.
Starting with a very little amount of theory, you’ll develop code right from the beginning. After you’ve completed this book, you’ll know enough to create your own BLE applications.
