DIY Transistor & Component Tester and its Surprisingly Useful 🤓

In this video, I demonstrate some of the useful features of a build it yourself transistor and component tester that can be purchased in kit form some assembly required batteries not included, of course lol I was always very skeptical of the usefulness of these types of devices, but I think I might’ve changed my mind as a quick verification tester. It’s really handy and definitely useful for most of all amateur electronics enthusiast. Let me know do you use one of these? Have you built one do you like it or have you ever run into false readings and if so, tell us in the comments what you were testing
