I got these lying around, the motors magnets are still there and usable. I wanna know what I can do with it.
I'm thinking of merging the three shafts to create one long and powerful motor but that seems like a long shot.
I want a good quality solder that I can find from a reliable and I want to make sure it's good enough so I can invest in it and not ruin my projects.
Im making an e reader using OLED screen
An SD card adapter.
Esp32.
It's got a small screen
I used Gemini and Claude to write code because idk how to code yet.
I'm very satisfied and I just have to get a boost module to support batteries, a case and some soldering before it comes fully together.
Please help it hurts and idk what to do
This a video of me blinking my first led on esp32!!!
Unfortunately my laptop was my brothers so I had to use Arduino droid because there was no driver in laptop. Could you believe it?
And I didn't have administrator permission so I couldn't install😭
YALL BE WORRYING SO MUCH BUT FYI I DID ADD A RESISTOR LATER SO PLEASE DW AND ITS 220 OHMS
is this even possible? i know html but java and python i dont even know anything about 😢
I saw this SD card reader and I need to know if it is compatible with esp32 because Gemini is saying that it is for Arduino's five volt supply.
Then it says I can connect to esp32 5v pin which gets even more confusing that how can it send 5v? It's for voltage regulation. BTW ITS AN ESP32 DEVKIT V1, SO SUGGESTIONS SHPULD MATCH THE BOARD
I want ot power it with rechargeable 3.7v li ion battery but I'm facing one issue: I don't understand how to keep it at 3.3v without spending any extra money. I can't find anything cheap and I was speculating on using the USB port instead
Please suggest some other way to make sure the output remains same which is 3.3v.
I'm making a mini kindle using an esp32 wroom
I will be also using 1.3inch 4 pin OLED screen
To store book data I'll be using and spi interface sd card reader
With a few buttons to go through the menu and pages of a book
I even have a great idea for housing all these parts
However I have minimum knowledge about robotics.
Adding a lithium ion battery as well with tp4056 and I need to know where I should connect that too.
Coding I'm thinking of using cursor to code the esp32
I just need help connecting pins and that's all.

THIS IMAGE IS NOT MINE ITS JUST THE INSPIRATION FOR THIS PROJECT, I PICKED IT FROM INETRNET.

I'm looking for a USB SOLDERING IRON.
PLEASE SUGGEST WHAT I SHOULD TRY AND GIEV ME A FEW LINKS WHERE I CAN FIND AFFORDABLE AND GOOD QUALITY IRONS WITHIN OR LOWER THAN TAHT RANGE.
MY RANGE IS 2-3K. (PKR)
I NEED SOMETHING WITH TEMP ADJUSTMENT, EVEN IF IT IS BASIC, AND RECHARGEABLE AND ALSO SMALL AND VERSATILE.
I recently started on a project for a diy drill with RS775 motor and when I came to power supply batteries were out of the question because it was getting complicated
​
So I decided to make the drill corded and use an external power supply by connecting with DC jack
​
I'm confused what amperage I should use, there are many options from 1 amp to 10 amp (12v).
​
Please advise me Im totally lost.
​
I've still got some wiring to do and I've got a lot of stuff to put it in and I wanna know what's the best option so I can test it out before completely shutting it.
I got around 4k at max and I need a something that can last
I found this drill set in Daraz(a pakistani site) and found it pretty cheap. Should I buy it
I found this old SONY diskman I plugged it in, but I don't understand why it's not showing signs of life.
Can anyone help me out? I would love to have it in working condition...
Also it did not have manual with it so I did not know how to troubleshoot. I tried putting batteries and plugging in and both same time but that didn't work either
How do I know it turns on also?
I don't understand this 3s bms thing at all because I just started electronics, so I need a connection diagram of sorts to connect my batteries to the circuit
I haven't bought it yet because none of the diagrams make sense
Please help me out😭
Also how do I solder batteries
I tried soldering them in series but solder won't melt on it, I'm afraid of it overheating
Also I don't have the nickel strip thing to connect batteries so I have no other option but to solder
