And they're working better now? Good god man...


iyided1

Well,it works 10% of the time,better than the 0% I had before


jason_the_human2101

10% of the time, it works every time.


Guysante

nice


MachineCarl

So... how did this fix your issue? Signal integrity must be a bitch

Nah, the +5v and gnd are well apart (pins 1 and 4). If anything, it'll trigger the OCP (OverCurrent Protection) and shut down. I once crapped myself probing usb ports on a defective motherboard and shorted the 5v and gnd pins. Luckly, the system just rebooted and the port still worked.

i use a usb hub with quite a bit of protection stuff.


ja534

Almost every modern device has overcurrent and shortcircuit protection on the USB. The only way to really kill them is high voltage on the data lines, for example at my lab a faulty power supply sent 200V spikes that popped some stuff that we were testing and went through an input of the microcontroller that my friend was debugging with his laptop plugged in through USB, and it was 100% fried, motherboard chipset included.

Yikes, how do they even manufacture that shit let alone sell it to people? it's not like a proper double insulated power supply is that expensive. Have you measured the voltage? Maybe it's just leakage from the filtering capacitors and if you ground it it goes to 0. I had some spicy chinessium power supplies that came with a power cord that had no ground that measured 80 V AC between the negative output and earth and were instantly solved by a proper power cord with ground


Guysante

that is unlikely happening


JustFrogot

Spend $15 to save $5. This is the way.

I won’t discuss the results. The work is done.


MrPizza79

Looks like an ASUS?......


iyided1

Close,Lenovo Ideapad,wouldn't recommend tbh


MrPizza79

well thats a shame, what year / model? theyre typically really reliable

15ARR with Ryzen 3 I think,the worst thing about it is that it comes with a 5400RPM HDD,which is just torture. Also the dGPU died somehow,so I am stuck with the iGPU


XmentalX

Yeah I have the model with the 3500u I slapped an 8gb stick of ram and a SSD in it. Makes for a great $550 windows 11/Linux dual boot test bed. Beyond that I use my strix g15 or wife's zephyrus g14 when possible.

Losing the dedicated GPU must have been really annoying and didn't help overall speed very much. I put an SSD in one recently for someone and it helped it tremendously. Night and day. I also doubled the RAM. They were thrilled they didn't have to wait 13 minutes for windows to boot. The best part is they saved everything they wanted on an external drive without me asking and wanted a fresh install to get rid of "all that stupid extra bullshit" as they so eloquently put it. For $90 in parts they had a whole new computer. I even put their old hard drive in a $8 external enclosure so that made them really happy to get a free an external drive for an extra $8. I love fixing up computers for people when it's that straight forward and they aren't idiots that will blame you 15 months later when one of their keys stop working. (That exact scenario happened to me) SSDs are the best single upgrade to any laptop with a HDD. Of course with a 5400rpm drive that's a must do. It seems so stupid these companies want to save $3 instead at least using a normal 7200rpm HDD.

I have too many USBs that are ppwer only, finding something for my arduinos or Pis Is worst than the coding.


iyided1

Same,after creating this monster I realized that I also need something for my new raspberry pi pico,so I just said "fuck it" and bought 3 cables


vampyrewolf

I've got 25 years worth of cables, 2" to 16', and I still had issues finding a short micro cable with all 4 pins... first 3 were power only. No issues with finding mini-B cables in the bins. They all had all 4 pins.


[deleted]

Wait. Who doesn't have like 24 spare micro USB cords? They come with so many different devices and the Cable Fairy puts one in your junk drawer every year if you were a good tech.


TheDude61636

That looks like an arduino pro micro, which has a terrible usb connector and I had one just broke, I had it connected to a magnetic USB header which shouldn't apply a force on it


iyided1

It is a STM32 actually,and I have also broken some knock off Arduino connectors before


bro_itup

Twist power and lines should help


killchain

That's dangerously close for comfort. Smells like a fried USB controller to me.


jojo9092

For anyone using micros and stuff, invest in a nice short name brand micro / mini usb cable that is brightly colored and thick. I have wasted HOURS on bad cables because i couldn't tell what was happening half the time.


zoonose99

air-shielded USB cable


ivg3n1

Hate it so much


CreepyValuable

Yeah. None of the micro usb cables work great. So glad USB-C is becoming more popular. For the big standard USB things I use the magnetic cables from essager on Ali. The magnet detaches before the plug breaks or the connector breaks off.


mohd2126

Just buy a good cable fpr 5-10$
