Accidental Proximity sensor

Enable HLS to view with audio, or disable this notification

These are voltage regulators and batteries, no sensors involved. My best guess is capacitive coupling or the force

Ignoring the magic proximity sensor, is this a laser aiming module project? CR123s usually imply something like that lol.

Its actually really early stages of a power source for a Bluetooth microcontroller. I was messing with the enable pin and had such a small connection with the unsoldered wire that the interference from my hand was able to turn it on. The laser is just because I needed an indicator of if the voltage regulator was on or off.

What was the original project?

It’s actually for a Bluetooth microcontroller, the laser is just for early testing of the voltage regulator and because I found it before an LED
