Welcome back to another exciting mailbag video! In this edition, we’ve got a fantastic selection of electronics modules, tools, and accessories that are sure to pique the interest of any hobbyist or tech enthusiast. From practical storage solutions to unique bargraph displays and rapid prototyping boards, this video is packed with gems that might just inspire your next project.
Kicking things off, we have a pair of EVA storage cases that are perfect for safely storing and transporting small devices like logic analyzers or firmware debug tools. These compact and affordable cases are a must-have for anyone who values organization and protection for their electronics. Next up, we have a fascinating LED bargraph module that caught my eye.
This round, 31-segment display is a true eye-catcher and can be used in various projects, such as level indicators or visual displays. With options for different colors like green, red, and yellow, these modules offer versatility and a touch of retro charm. For those who frequently work with ESP32 or compatible modules, the prototyping PCBs featured in this video are a game-changer.
These boards allow for rapid prototyping and easy access to all pins, making them invaluable tools for any maker or developer. But that’s not all! We also explore a range of other exciting products, including a bicycle pump valve replacement, pneumatic fittings, high-quality cigarette lighter connectors (with a rant about delivery restrictions), connector adapters, USB Power Delivery decoy modules, and even an EMI filter module for power supply noise suppression.
