These days good quality oscilloscope is not an expensive instrument and, we can see it in most workbenches. With the advancement of oscilloscopes, simple testing tools such as logic probes are not as popular these days.

That means reading various manuals/instructions, but better than causing damage, injury or worse by using the wrong batteries.
By day I am an electronic engineer for a certification and approvals company, by night I am an avid technology hobbyist and DIY'er. I enjoy learning how things work, and sharing my learning experiences with others. I enjoy reading projects by other makers and attempting to make my own version.
We're making a small macro keypad for some keyboard shortcuts. In this case, it is for Zoom video conferencing shortcuts for Windows. We'll program the keys to toggle mute/unmute microphone, raise/lower hand, and video on/off.
I developed 40+ games, challenges and miscellaneous activities for the “mini STEM platform”, as an aid in advancing STEM education
Bluetooth Zoom/OBS Controller
The display is a bit absurd, as it takes a much larger grid of LEDs (64 square inches) and condenses them down to a much smaller size (1.5 square inches).
