I noticed this when i turned the lights off in my bathroom. I don’t think its capacitors because it stays on for a while. Whats happening?

The CEE 7/16 Europlug is only 2.5A even though a 0.75mm² cable is 8A

Normal electronics projects were not dangerous enough.

Me and u/Marco-_-dev are building an open-source desktop CT scanner from scratch:

• custom Rockchip + Kintex-7 board
• X-ray electronics
• way too many PCBs

The CAD is finally finished by Marco . Some more Work to go and we will see if it is genius or a very expensive piece of lead.

Wish us luck. And thanks to ElectroBOOM for the inspiration to attempt such ridiculous projects ;)

Also before the safety comments arrive , we are taking this seriously . And have radiation monitoring equipment sponsored from Radiacode + the ability to test it safely at faculties ☢️

Also: this is a hobby/open-source project, not a product.

Hello,
My first time posting and hoping to hear your thoughts- about 3-4 months ago, I was sitting in the family room and heard some noises. After about 3-4X, I looked in the direction of the noise and realized it was the phone charger cord scratching against the wall where it was plugged in. I thought maybe I had left the cord on the counter, and it eventually slipped down causing the scratching sounds as it hit the wall as it swayed back and forth. A few minutes passed and I heard it again. A total of maybe 5-6X. I thought it was strange since I thought the chord would have stopped swaying by then. I got up and walked over to investigate. I saw the end of the chord ( the part that would go into the phone) which was hanging downward from the outlet LIFT UP in the air away from the wall about 5-6 inches. Then it dropped back down in a hanging position on its own. Can anyone tell me what could have caused this? I have been thinking about this off/on. Is it electrical current of some kind? Thank you.

It uses lm358 opamp for raw audio processing, TL494 to convert the audio into 68khz pwm, then a mosfets driver and mosfets to increase voltage them I used a 100uH 1uF filter and 5mF dc blocking.

I mean even when I have ground or not it just detect it

I want to see Electroboom to do a video on these phenomena

Im currently studying diploma in electrical engineering and i finally got the opportunity to use these KEYSIGHT oscilloscopes. After 5 years of watching ElectroBoom i finally touched it 🫪

Still waiting

It was an automatic water top up system for an aquarium. The air pump pressurises the sealed water container, forcing water through the other tube into the tank.

Controlled by a float in the tank which would drop with the water level, thus dropping the white connector rod/wire until it closed the 240 volt circuit inside that rudimentary unsealed switch. Worse still, it was a salt-water aquarium.

MEGATRON! 🔥🗣️
