Sometimes it is hard to probe a circuit and then look over at the meter. [Electronoobs] decided to fix that problem by making a Google Glass-like multimeter using an OLED screen and Bluetooth module.
The custom PCB doesn’t have many surprises. A small board has a controller, a battery charger, a display, and a Bluetooth module. One thing he did forget is a switch, though, so the board is always on unless you arrange an external switch.
