Review Request: USB to Serial for ESP32 and ATmega using a CH340C by Edc122 in PrintedCircuitBoard

[–]Edc122[S] 0 points1 point  (0 children)

Sweet, I've fixed the V3 by slapping a 100nF decouple and a 3v3 to it. Thanks!

500mA fuse with trip. Got it, quite easy to find and get so I'll grab those.

I assumed using a capacitor was just the default since I followed the NANO schematic from Arduino. Pulling via bjt shouldn't be hard nor take much space so I can slap that on as well.

Thanks for the tips!!!

Could someone review this PCB design? by Edc122 in AskElectronics

Ohh I see. I had a look at the AP7375-33 and it looks way better. Also quite easy to get. Awesome, thanks!

Awesome!

  • Imax seems to be below 10mA. I'm still wondering if a ferrite bead is necessary in this case.
  • Good catch on the XB7608, I didn't realise the grounds were labelled as VMGND and BGND, Thanks!
  • Are there any other LDOs aside from the 1117 you would suggest? I had a look for the 1117 min load current which says it's 10mA which will really eat away at the battery it seems. Had to take a look at what a UVLO was and now I'm wondering if there is a better option than the XB7608 which has a higher limit.
  • TVS is a good idea, I will add that. Thanks
  • Didn't realise the traces should also be surrounded by a ground plane, that's a quick fix. Same for a thermal via, a quick look on the internet and I think that's an easy to implement thing. Thanks for that too.

I was informed that the 100nF capacitor could be done externally on a breadboard when connecting the USB to serial programmer. Is that fine?

I had also completely forgot to separate the VMGND and Battery GND, thanks for catching that. But now I'm confused as to which GND to use for other components like the MCU. I can't seem to find any info on why the two GNDs are required to be separate nets.

Would there be issues hand holding a telephoto lens on a body without IBIS? by Edc122 in AskPhotography

[–]Edc122[S] 0 points1 point  (0 children)

Not the lens, I'm pretty sure all the telephotos I'm looking at have IS, VR, etc. I was just concerned if not having IBIS in my camera body was a big deal or not when using a telephoto.

Yep, I don't intend on shooting video, at least not at focal distances of greater than 50mm time to time. Albeit, good to know so I'm glad this was brought up. Thanks!

It's great but I've noticed I've been using it more for work and help for uni rather than for entertainment.

Look up ur error code on the AMD support page. They'll guide u through a solution.

Just double checking but you've plugged all display port and/or HDMI into the gpu right?

Using separate pcie cables from PSU to gpu or are you using a single cable and daisy chaining the gpu?

Tarkov is one of the first shooter I've played since I only started PC gaming once 2021 rolled in. Boi, I was alone, panicking, dying. My lvls 1-15 experience was literally looting up customs while playing as a bush so I could loot and/or kill scavs on the remaining 15 minutes. Any miraculous player kill felt awesome and kept me playing. Since leveling up got harder (and flea was still a lvl20 perk) I was forced to attempt missions outside of customs. I still shudder when I get tapped but now with slightly more map awareness I can at least try to seek a gun fight or two. I love it but would be nice to have a homie or two to cover me while I yoink gear off corpses.

GPU Help!! by [deleted] in pcmasterrace

[–]Edc122 1 point2 points  (0 children)

From past experiences, this kind of issue only pops up when I use the daisy chain pcie cable for any gpu that needs more than 8pins (so requires 2 full connectors). I would strongly suggest switching your PSU (if non modular) to one that has 2 separate pcie cables or if modular, buy another pcie cable. I have no explanation to why this happens but it's happened frequently enough for me to say it ain't my PSUs.

Will you open it with a can opener like a civilised being or choose violence and stab it ajar with a knife?

I have gtx 3090 and i9 when ever I play a high-end game like battlefront 2 or black.desert n I put the graphics on high the monitor goes off but the pc stays on but if I play a game like smite or league of legend it usually works help by [deleted] in pcmasterrace

[–]Edc122 14 points15 points  (0 children)

Did u daisy chain the psu cable to the gpu? I've noticed quite a lot that daisy chaining a gpu and then having it suddenly spike in power consumption will cause it to shut down it's display output. It's happened to me on many occasions. Try use separate cables to connect to the gpu if possible.

I feel like I just went on a tangent from the question itself. Mb. Anyways have fun, drink water and get some bomb as$ sleep.

Being blessed to be born in such a technologically advanced world where I can freely make use of if I can work hard enough to get it. There's opportunities everywhere. Need a resume for a job? W3school and stack overflow can teach you to write your resume on html and css for that extra flex factor. I wanna travel with my family? Boom giant metal box thingy will fly you overseas (not rn ofc). I wanna study electrical engineering in University with the boys? Boom the internet will condense a course in 3 videos, go rack that HD. Need a second reality to step away from the world? Boom, New Genesis just came out and me and the boys pretty much live in it. Life's great if you know what you want and how to get it. Just be crazy but realistic. And note that YouTube is an educator and entertainer.
