RF Hacking A Ceiling Fan Via The Remote
Sam Wilkinson recently tackled a common issue with his Dreo CLF513S ceiling fan, which only operated through a cloud-based smart home setup. To create a more flexible solution, he decided to hack the fan's remote control, which operates on radio frequency (RF), specifically at 433.92 MHz. This frequency is typical for many consumer appliances, allowing for communication without a direct line of sight.
A remote web rig control system for the Albrecht AE-5900 radio #HamSunday
The AE5900 Remote Control V2 is a Python-based project designed to enable remote control of the Albrecht AE-5900 radio over a local area network (LAN) or the web. While it may not offer the same capabilities as established software like rigctl or hamlib, it provides a functional solution for remotely operating the radio. The initiative aims to breathe new life into Citizens Band (CB) radio by making it more accessible and appealing to users.
Spotify Music Display with a RGB LED Matrix
Mewtru has created an impressive project that displays Spotify album art using a 64x64 RGB LED matrix. By leveraging the Adafruit Matrix Bonnet and a Raspberry Pi Zero, this setup spins the album art like a vinyl record while a song is playing. When the music pauses, the display stops at the current angle, giving a cool visual effect that mimics a spinning record.
MUNNY Glowing Friend with Bluetooth Control!
MUNNY is a customizable designer toy figure that can be transformed into an interactive glowing buddy using electronics. The project allows you to fill MUNNY with hardware that enables it to emit a rainbow of colors, all controlled wirelessly via Bluetooth. This makes it not just a fun art project but also an engaging tech demonstration.
EEVblog 1755 – Tolicore Femtoammeter TEARDOWN + REVERSE ENGINEER
The article covers a detailed teardown and reverse engineering of the Tolicore 3720 Femtoammeter, which is a highly sensitive device used for measuring extremely low currents and providing a voltage source. The video starts with an unboxing and power-up of the femtoammeter, showcasing its user interface and features like a 20 pA full-scale range. It highlights the instrument's impressive sensitivity and its Bluetooth capability, which could be useful for remote monitoring and data collection.
Designing a Tuneable Ultrasonic Filter
The article details the design of a tunable band-pass filter that operates within the ultrasonic frequency range of 20 kHz to 60 kHz, complete with an integrated frequency counter for precise tuning. This project is aimed at hobbyists and engineers looking to create a filter that maintains a constant bandwidth while allowing for adjustable frequency selection.
A 7 to 60 V Input Buck Converter: A Wide-Range DC-DC Step-Down Module
This article details the construction of a versatile DC-DC buck converter that can handle input voltages from 7 to 60 volts while providing a stable output of either 5.0 or 3.3 volts. The design is particularly useful for applications where you need to step down a higher voltage to a lower, regulated voltage for powering various electronic components.
