Which model should i buy?

I'm an engineering student who completed his 1st year without college and as RAM hike got increased, I've decided to buy 2nd hand thinkpad but there's a problem about what model should I buy?

My purpose of having laptop is:

Cybersec

Development

Embedded programming

PCB designing

using fusion360 for CAD design only

And ML(not my first priority, can skip it)

Now, I've checked my requirements that i need something

i5/i7 10th-11th gen CPU

16 GB RAM

512 GB SSD

What else do I need? Also, as I'm buying it 2nd hand, so I know about battery health also....

Also, the budget I've is rn, 30k-50k INR cuz I'm buying it as 2nd hand.

So, help me guys, regarding this....

Gonna make it alive and see if it works....

Just, I need to upload code... which is very hard thing... so that it can work, then I'm planning to create custom cam for me and esp32 aesthetic digicam so that people find it fascinating and I make money from this....

Update: i don't have any idea how to code in this, like to create this full project.... I tried claude and shit tons of yt videos but I can't find a complete thing to make it work

In camera webserver example code, I'm using CAMERA_MODEL_ESP32S3_EYE and it works and wiring is like

BL -> GPIO38 MOSI -> GPIO20 CLK -> GPIO19 DC -> GPIO47 RST -> GPIO21

For ST7789 7 pins screen

And push button connected to 42

I didn't got any code regarding this but something close {credit: some Indonesian}

So help me regarding this also, how to change config in TFT_eSPI like user_setup thing, I couldn't understand.

Planning to buy this

I'm an engineering student in India, i don't have personal laptop, i saw this laptop, ThinkPad X13, 2nd hand, 28K INR. So, I'm planning to buy this, all I need to do is learning some ML, do some basic CAD from Fusion360..... and other field such as cybersec, Embedded, Coding and college work and all... so is it good?

Update, no luck

Why is it happening? I tried everything already but no luck.... i mean changed all the wiring, tried with another microcontroller and changed board setting, all of it multiple times still nothing happened.

Having issues to upload code in esp32 cam

Well, I got esp32cam which i taken from friend, it was working alright, but now, as I'm trying to upload code, it having problem, that it's not reading serial and all, I tried it multiple times, tried multiple approaches, worked on esp32s3 cam recently it was working but this board being pain in my ass. Also tell me, should I do UART connection as

RX->RX, TX->TX

Mr

RX->TX, TX->RX

PS: I'm posting again as last post was deleted(i haven't read the rules)

Edit: I did circuit as

Esp32 5v—>cam 5v Esp32 gnd—>cam gnd Esp32 rx—>cam tx Esp32 tx—>cam rx Esp32 en—>esp32 gnd Cam io0—>cam gnd

Using esp32 as ttl, by disabling chip....

Update: The board is fucked up, seeing 3.75v on 3v3 pin(it should've been 3.25-3.35v but it's not)
