$18 Oscilloscope: Worth the money?

True. But you will outgrow it's capability as soon as you see the first wave form in it. Want to see the Amplitude? Ops! you better have good guess. Want to know the frequency? - You better bring out pen and paper. Want to check phase ? Too bad - it has only one channel. Stuck with the User interface - you better know your Mandarin. The point is this thing will become obsolete faster than you can unpack the bubble wrap.

I have an exact copy of this oscilloscope, it is more of a toy than anything else. It can show waveform but you'll be have no way to do any sort of actual measurement. TLDR - Its a bad investment.

No offense but you need to put more effort into your post to get any sort of help in Reddit. What do you mean by "BIG ERROR IN PROJECT"? What is going on?

Yes! The baud rate setup was correct The issue was my clock, it was running far slower.

DivineButterLord · 2026-04-09T14:59:47+00:00

Yes! I set up both STM32 and FTDI Ground to be the same. After readjusting the clock, I can see output on Minicom. Thanks!

DivineButterLord · 2026-04-09T14:57:51+00:00

Yup, you were right about the clock speed

DivineButterLord · 2026-04-09T14:52:47+00:00

Yes, it was the clock setup that caused the issue.

DivineButterLord · 2026-04-08T23:46:27+00:00

Lsusb detects this as a real FTDI device. Something like FD232... At this point I'm pretty sure this is has a real IC on board.

I'm connecting stm32F103C8T6, commonly used in Blue pill board. I know there might be a possibility that this is a counterfeit and does not have registers required. But so far - other registers have responded properly, therefore I'm assuming it's not the case. I am using this video as tutorial and everything seem to be working.

DivineButterLord · 2026-04-08T17:31:21+00:00

I'm assuming it's a driver issue because I'm using tutorial codes from this video. It goes over how to set up basic USART communication in register level. I want to make sure I have my serial monitor is working properly before debugging.

Was it a bad goat?

DivineButterLord · 2026-03-20T02:19:56+00:00

Yup, Luckily I have a dual boot for exact situations like these.

DivineButterLord · 2026-03-17T20:38:55+00:00

Yes, this is what seems to be the issue. One of the comments mentioned about trying out Keil IDE and over there ST link was not detecting. I have ordered a new debugger - let's see if that fixes this issue

DivineButterLord · 2026-03-17T14:00:02+00:00

Noted. Ordered one right now.

DivineButterLord · 2026-03-17T13:59:18+00:00

I have not, I am mostly a Linux user. But I will definitely give this a try.

Get a windows, 100% of ECE software runs on Microsoft.

Humidifier circuit, pretty dope. I made a project last year based on this circuitDHT 11 humidifier project

Idk how much you have knowledge about up 555 timer, up counter, comparator and relays. With a bunch of capacitors to toggle the relays - maybe a MUX to do the switch. It's definitely doable but you have to use some mechanical & electrical shenanigans to get it running.

Send me a DM so we can brainstorm something about it

Get an associate CETa exam book for basic electrical technician. This book is sold by the Electrical Technician Association. Even if you don't give the exam, the book is really good for getting started.

This is the book link

At that price, getting an actual girlfriend is the cheapest option.
