Versatile Repair Box for Electronics Enthusiasts
For electronics enthusiasts, equipment maintenance is essential in daily life. Having a reliable and user-friendly tool can greatly enhance efficiency. Below, I'll share the process of creating a versatile repair box (the entire circuit topology will be presented at the end).
1. Introduction to the Finished Product and Its Functions
1.1 Appearance of the Finished Product:
The repair box is based on an 86-type three-gang surface-mount box, containing all the components and circuit boards. Instead of having just a repair socket (which might be infrequently used and take up space), we've incorporated some commonly used repair functions. Therefore, there are two sets of schemes provided (with a focus on the second one). You can modify it according to your needs. Please refer to the sample images of the finished product.
Scheme 1 (Fewer functions, larger size, bulky):
Top view
Front view
Back view (The light bulb can be removed when not in use, and for safety, a cover is added.)
The bulb is compact for easy movement and storage when not in use.
Scheme 2 (More functions, reduced size, improved aesthetics):
Top view
Front view
Left side view
Right side view
Back view
2. Function Introduction:
a. Power Monitoring Device: It offers six functions, including voltage, current, power, power factor, electricity consumption, and frequency monitoring.
b. Series Lamp Maintenance Socket: Prevents the range of damage from expanding when repairing electrical appliances with a short circuit.
c. 4-port USB Charging (5V, 2A).
d. Lithium-ion Battery Balancing Charger for hand drills.
e. LED Testing and Polarity Determination.
f. Infrared Remote Control Testing for functionality.
g. Adjustable PWM Pulse Frequency and Duty Cycle Square Wave Signal Generator.
h. Audio Tracing (expandable to high-frequency tracing function).
i. Bluetooth Audio Reception (can be combined with audio tracing to create a Bluetooth audio player, and can later be equipped with SD card MP3 playback functionality).
In conclusion, the DIY repair box presented here is an absolute game-changer for electronics enthusiasts and professionals alike! With its multifunctional capabilities, sleek design, and user-friendly features, this all-in-one device is a must-have tool for anyone dealing with electronic devices in their daily life. From power monitoring to LED testing, from audio tracing to Bluetooth audio reception, this versatile box covers it all! Whether you're a seasoned hobbyist or a skilled technician, this compact and efficient gadget will undoubtedly enhance your electronic repair experience.
