Smart home devices are entering our private homes but also offices, hotel rooms and public areas. They are not only for convenience, but play an increasing role when it comes to energy saving. Modern room thermostats for example adjust heating behaviour to suit occupants by using adaptive control functions. These thermostats are available as simple temperature regulators but also smart controls for automated heating and cooling. Devices are either stand-alone solutions controlled via an app or fully connected, professional installation bus systems based on standards like KNX.

Diotec's Linear Voltage Regulator LDI1117-3.3U is used in the power supply of the embedded microcontroller of such smart home devices. It offers a stable 3.3 V output with integrated current limiting and thermal overload protection. As such, reliable function is ensured over a long lifetime.

Not only heat control and air condition, but also lighting, window and door opening, shading and presence control are managed by smart home devices. Though the contribute of energy saving by each single control might be small, in a global view it will be an important amount of electricity saved and thus environment protected.

This excellent walking humanoid can move almost like a "live" human.

There are various sensors installed with programmed movements that you can control via the joystick, such as: Walking, posture change, demonstration movements, soccer movements and fighting movements. For each movement you have to press a certain "button". There is even a sensor that makes the robot move when you move in front of it. For example, if you clap your hands 10 times, the robot will do the same. The robot walks by itself and avoids obstacles. When the absolute distance sensor detects an obstacle, the robot stops and turns to the left until the obstacle is no longer detected. If it falls down while walking, it gets back up in the direction it was moving. The poses can be adjusted as well. All you have to do is turn off all the motors and then readjust the robot's pose. The presentation at electronica India was very successful, as visitors were amazed by the funny, agile movements.

Diotec's MMBT2222A and MMBT2907A Small Signal Transistors are installed in the robot's joints and control the DC motors for movement. For more instructions, you can check here:https://emanual.robotis.com/docs/en/edu/bioloid/premium/

A good gaming headset is important for online gaming, especially for eSports tournaments. Acoustically, it immerses you in a world where you feel like you are right in the middle of the action, while at the same time you are able to hear your opponents in the game clearly and without interference. The wireless gaming headphones come with two noise-canceling microphones and a USB port for charging. The setup can be adjusted with integrated controls like the microphone's mute, master volume, and mix ratio while you're having fun. The headset is compatible with all major consoles and PCs. When connected to a PC, the headphones have 3D sound quality, which improves your gaming experience.

Diotec’s Voltage Regulator LDI8119-05EN Series, with a fixed output voltage of 1.8 V to 5.0 V and an output current of 500 mA, provides an efficient and stable reference voltage to the circuit. It also comes with the EN-function, which can be turned on or off, helping to prolong battery life. With a typical quiescent current of 1.8µA, it reduces the power loss in run mode. This helps the overall system achieve better efficiency. Typical applications include all kinds of wireless, battery-powered devices such as gaming headsets, computer mice, keyboards, and more.

The sports and fitness industries have experienced a revolution thanks to semiconductor chips.

Sport and fitness are data-driven activities. This information will be analysed by technicians for further decision-making. Most of the strategic solutions in the modern sporting industry depend on electronic analytics. Football tracking technology has become popular in most games. The device has sensors that connect to and transmit all the necessary information from the ball. It provides information on the exact position of the ball on the pitch, the angle from the ground, and other data. E.g., we saw improvements on the field of play in the arena in late 2022 in Qatar, including the World Cup. This data collection is pertinent to the continual improvement of how the event runs and football itself.

It will be interesting to see what happens between now and the next World Cup. Diotec's bridge rectifier, the GBU12M, is used in the seat heating of the coach bench, nowadays modified car seats. This bridge rectifier comes in a slim GBU case outline and offers a sporty 12 A output rating. It features an unbeatable 270 A of forward surge current at 50 Hz/10 ms pulses. Reverse voltage is 1000 V at high tension; it manages to rectify any AC from the electric mains into DC with the heat resistor as the load. The current flow is trimmed by a MOSFET, driven by the temperature control, in order to keep the seat warm as desired. The GBU itself should not get too warm; therefore, it can be easily assembled onto a heat dissipator. The GBU12M is packed in trays, while its buddy, the GBU12M-T, is supplied in tubes, for easy automatic assembly.
