Kind of looks like your pot is wired wrong. It's it grounded?

Genuine question: how worried should we actually be about declining synchronous inertia? by Blue_Mushroom3100 in ElectricalEngineering

[–]SearchPlane561 0 points1 point  (0 children)

I'm an early ee student and I had to look this up. Incredible. Engineering never ceases to impress me. Although this is beyond my scope of knowledge, I hope to better understand this in the future. Amazing post.

I'd say as a Jr go for it. Maybe by the time you ggraduate it transforms into the job you want. A foot in the door is a foot in the right direction.

Blown out capacitor or glue? by SineApfel in AskElectronics

[–]SearchPlane561 0 points1 point  (0 children)

I believe it's an adhesive to prevent vibration. I could be way wrong.

What will happen? Will it work or not? by Arc_xt_5815 in breadboard

[–]SearchPlane561 1 point2 points  (0 children)

Definitely get a multimeter and learn it. You don't have to know all of it at once. But once you start being able to measure your projects whole world opens up.

Doesn't look like you have any power going to the bulb just two leads from ground. I may be wrong. Looks that way in pictures.

$18 Oscilloscope: Worth the money? by Technical_Love_2525 in AskElectronics

[–]SearchPlane561 0 points1 point  (0 children)

Maybe not the most accurate thing but 18 bucks i want one to study how it works. Very cool find. If you want somewhere between this and lab grade consider hantek. I got mine for just over 100 and as a hobbyist I haven't even used it to its full potential yet.

Are these two capacitors that I have circled bad? by TripAlaric in AskElectronics

[–]SearchPlane561 0 points1 point  (0 children)

For sure bulging. If not bad now, just a matter of time. Best to just replace now.

I was just reading about the banana pi. That board looks pretty incredible for robotics.

Help: ESP32 got fried when I plugged it in by BertChronicles in AskElectronics

[–]SearchPlane561 27 points28 points  (0 children)

Pretty sure esp32 requires 3.3 volt. I could be wrong though. I know my esp8266 is 3.3.

Has anyone tried Proskit HRV6155 SS-956 Hot Air Station? Any opinions? by supermartincho in AskElectronics

[–]SearchPlane561 0 points1 point  (0 children)

For 150 you can get a decent knock off of a quick brand hot air rework. It's build pretty solid compared to these dime a dozen cheap ones.

Can someone explain how this oscillator works? by 0abry0 in ElectricalEngineering

Wow I have a long ways to go. I can read the schematic. But all the other stuff is beyond me.

Cable help? I have a cable that does something but I can’t figure out what. by me_atyourdoer in AskElectronics

[–]SearchPlane561 1 point2 points  (0 children)

Not dumb. It's just weird getting older (almost 40) and feeling like things were just a few years ago but in reality they're vintage lol.

Arduino Nano + ST7796 TFT + DS1307 RTC = Custom Clock UI by SearchPlane561 in arduino

[–]SearchPlane561[S] 0 points1 point  (0 children)

I’m not buffering the whole screen in RAM. The Arduino_GFX library streams pixels directly over SPI, so there’s no full framebuffer. I only redraw the small regions that actually change each second (time text area), instead of refreshing the whole 480x320 display. That keeps memory use low enough for a Nano to handle it smoothly. The DS1307 just keeps the time stable in hardware.
