Getting Started with the PUI Audio AMP2X15 Audio Amplifier Board and Speakers Adding a speaker to an embedded project is not always as simple as connecting it directly to a microcontroller or single-board computer. Most audio sources provide a relatively low-level signal, while a speaker needs more power to produce useful sound output. This is where an audio amplifier becomes important. The PUI Audio AMP2X15 is designed to bridge this gap,… |

Clock Uses Water Bottles as Pixels With Membrane Pumps and Servos Maker Strange Inventions has built a water-based digital clock in which 60 small bottles act as individual pixels, collectively forming numerals to display the time. The bottles, sourced at 10 cents each, brought the total project cost to approximately $580. Each bottle is filled or emptied with dyed water to switch its pixel state on or off, with the display controlled by a microcontroller… |

Run USB Devices Off Your Bench Power Supply With USBpwrMe KS Elektronikdesign is soon to launch the USBpwrMe on Crowd Supply, an adapter that can be used to power USB devices directly from a bench power supply. It supports USB Type-A and Type-C ports, operates from 3 V–20 V, and can perform charge negotiation at 5 V. Both ports can be used simultaneously; however, the campaign notes that only one USB output should be used at max load. To… |

Exploring PD240W: Using USB Power Delivery as a Bench Supply Alternative Bulky bench power supplies and dedicated adapters are still common on electronics workbenches, but they are often inconvenient to carry around and overkill for many portable or field setups. With USB Power Delivery and newer GaN chargers now able to provide high power from compact adapters, developers are starting to treat USB-C as a serious power source rather than just a charging port. Theo… |

REF67004 is ROHM's New Power Supply Design that Combines Analog and Digital Control Traditional analog power supplies struggle to keep up with today’s performance and control accuracy requirements, which have gotten way stricter. Even though digital power supplies work better, they’re just too expensive and use too much power for smaller industrial applications. This makes their use limited. To counter this, ROHM has just announced a new reference design for power supply… |
