Welcome adventurer

Hey.

Ahh, February! 14th the perfect time to get good news, I guess ?

So I enrolled in this program called “LaunchX” sponsored (I don’t really know how it works) by Microsoft where you have the chance to learn how to be a developer (FrontEnd and BackEnd), the first assignment was doing some python programs and upload the results, the programs were not that hard, but I can understand that it could be a little much if this is your first time at it (I forgot to mention that the program is open for everyone).

I pass that step, and now I wait for the FrontEnd course to begin, to be honest I never really cared about Web Development, but some projects I’ve in mind might benefit from it, so here we go, it’s going to be interesting.

Btw I’m still at my Masters, and soon I’ll start writing my Thesis.

Hey.

So I guess that at this point everybody knows or knows somebody who knows or has a 3D printer, in case you’ve missed it (somehow ?) I present to you the 3D printer

Now that We’ve the same idea I’ll continue, so I have a 3D printer that helped me many times through college, many projects (and way too many internet memes) were done on that printer, eventually I had to leave it cause I graduated and didn’t need more pieces, so all is hunky-dory in the story c:.

Fast-forward to some months, I wanted to print a chassis for a robot, sliced the model, fired up the printer and let it go but after a couple of minutes the printer’s buzzer starts to sound, it rebooted, and I was left wondering What the hell happened.

So naturally I tried again, because if something fails you must try again under the same circumstances to see if it was a fluke (sometimes it is but most of the time it doesn’t :sadface: ) I ended up with 3 fail prints and me wondering why it failed out of the blue, this is what happened next.

1. Wondered if a cockroach eat the wires
2. delete the last idea
3. Maybe it was the software (sure, working software will blow up just because it’s a Monday)
4. Recompile the software
5. Upload the software (perhaps I solved it)
6. tried again C: (I think I got it)
7. Resets :c
8. Repeat steps 3 to 7 four more times

Ok, at that point I was mad, how on earth did that happen? Dunno, but it did.

I concluded that the main board was fried, so I went to AliExpress and bought a new one (I had the SKR 1.4 with apparently is now deprecated so I had to choose the SKR 2.0)

After a couple of weeks it arrived at my door, I got excited because I could print again, so I teared it apart and replace the board, flash the firmware (I’ll write another post about it cause it’s actually quite interesting) and got another reset, by that point I was like this.

After all the mumbo jumbo I resourced to google, I don’t remember how I search for it, it was something like “3D printer turns off help me :sadface:” maybe not, but you got the idea. Some googling after I stumble upon an old forum post where they said that eventually the output capacitors in the PSU die after sometime, thus they don’t regulate the voltage as good and a brownout occurs (the voltage in the microcontroller goes below a certain threshold, the microcontroller sees this a problem and turns off everything including itself).

Now I have two working boards and a faulty PSU, I mean at least I know what’s broken

bye.

Hey. it’s has been a while but hey I’m still alive, this last few months I’ve been very busy with the school and some other projects and haven’t had time to write, but I’m back.

In the meantime I finished my first semester of my masters and I’m about to finish the second (the time flies D:), I build my first PC from the ground up, it was a terrifying experience to be honest, the part of getting all the parts was so slow, cof cof GPU shortage cof but once i had all the parts i build the test rig to see if it turn on and gave a video signal.

I tried for probably 20mn to secure the air cooler I was terrified of messing up anything, so after shaking like crazy, and been nervous I plug everything, short the power pins and it turn on (this mean that all the components were ok and i could move on)

And I’ve been moving all my files and installing programs, I’m thinking about starting a twitch channel of me doing stuff about electronics, i love the idea I’ll post about it soon. Happy xmas and new years (if i don’t update until then)

bye.
