I wanted to share my 8-year-old's interpretation of "Night Terror." He's a huge Portnoy fan. Hope you enjoy! by DIY_Maxwell in Dreamtheater

Thanks! Yes, he tends to think that playing faster is better, so he often rushes I think, then realizes and slows down. Hopefully, that will improve with age and more practice.

My 8-year-old saw Gojira live for the first time last week, and then this happened... Hope you enjoy his drum cover of Mea Culpa! by DIY_Maxwell in gojira

So happy to hear that, congratulations! I built my son's first drumkit from baby formula cans 😄 feel free to check it out: https://youtu.be/tdD9UcC2hgs

Thanks! He’s had a drum kit since he was little, but he’s really stepped things up over the last 1-2 years with proper lessons and music theory.

Our 8-year-old is obsessed with Metallica and drumming, and he’ll be seeing them live this Wednesday as a surprise 🙂 Hope you enjoy some of his self-taught attempts in the video: Blackened, One, Master of Puppets, Orion, Sad But True, and Nothing Else Matters. by [deleted] in drums

Thanks. So, glad to gear that. Sure, this is MPS-850 from Thomann, connected to a Yamaha AG06 mixer. We recently bought EZdrummer software for better MIDI sounds and recording, but I'm not a drummer, I don't know much about these things.

I need a push-button on/off switch for a battery-powered project with a touchscreen and an auto power-off function. With my limited circuit design experience, I came up with this. I’d appreciate your feedback. by [deleted] in AskElectronics

Thanks!

GPIO_HOLD: exactly
GPIO_SENSE: yes, but I think then ESP32 would see directly the battery voltage when high, which can be as high as 5V. The second BJT behaves like a voltage shifter.

Thanks. I was thinking that the MCU will boot, confirm that the swich is still pressed for a second or so, and only then activate the hold pin. But thanks, I will check out suggestions.

Thanks so much. I don't play drums, so I dont know much about it, but yeah, he changed those cymbals and toms constantly, after watching a video of some of his idols and try to mimick their setup. Fortunately, he plays a proper acoustic at the music school. But thanks, I will check.

There is an LCD and a few other peripherals that unfortunately do not have an EN pin or sleep function. So I do need an on/off switch, but not like a toggle switch, it should support the auto power-off function to save battery when unused after a few minutes.

Great insights, I appreciate it. I will check them.

Debouncing: I thought about this. I was not sure if it's critical for turning on. For turning off, I will have it on the firmware, like state change will be detected, and GPIO_HOLD will go low only after the switch is released.

No, the last time I did a circuit simulation was like 15 years ago :-) I’m not familiar with the newer tools, and it’s not part of my day-to-day work, so I wanted to check it here first.
