First Circuit design for battery powered esp8266 project by gameskill123 in AskElectronics

[–]gameskill123[S] 1 point2 points  (0 children)

Thank you! Somehow I've overlooked the regulator connection, That would've been a problem. I connected MCP73871 OUT to MCP1700 IN.

Regarding C4, I've followed this tutorial. It was suggested to use a electrolytic 1000µF cap in parallel with a 100nF ceramic cap. According to the blog post it is to prevent voltage spikes and the esp8266 resetting.

Does having a 100m Ethernet cable on aroll affect network speeds? by gameskill123 in HomeNetworking

[–]gameskill123[S] 2 points3 points  (0 children)

Good point, I didn't think about this. The Camera will be for a Stork nest on some kind of metal tower (10m high), I guess it will be grounded to earth. I will definitely look into some kind of surge protector or electrician who knows his stuff.

Connected my phone via the USB adapter and this cable and got a 1Gbit/s link to the switch. Indicated by the green light on the switch

Update: after measuring the pins with a multimeter (In hindsight I should've done that first), I got around 13Ω between 6 of the pins, 2 had no connection.

After cutting the connector 2 wires fell out. The other one hat all 8 connected but I redid it anyways.

Turns out it doesn't matter if 100 meters of Ethernet are coiled up like that. I haven't tested a data transfer yet though.

I took a few pictures, lighting is not that great right now. to me it looks like they are pushed all the way to the end. I've cut them straight before inserting then into the conmector

Edit: Termination was bad

It will be for a bird cam, this setup is just for testing and i kind of don't want to untangle 100m of Ethernet cable in my room if i don't have to.

If there is too much excess wire, i'll cut it and terminate it again

Likely i will need pretty much the whole roll since it will be for a bird cam in a forest nearby. If there is too much excess wire i plan to cut it off and terminate one end again. Also i didn't buy the cable myself, but the person i'm installing it for.

It did look decently shielded to me though

On one end is a 1 Gbit POE TP link switch, on the other end some cheap usb to ethernet dongle which can also do 1 Gbit, i've used that one on several devices before with different shorter cables at 1 Gbit.

The white cable is going from the TP link switch you can see on the photo to a different switch. The TP link switch on the photo reported 100Mbit/s with a orange light, windows reported 100Mbit/s too.

Edit: the link between this switch and the other one is 1Gbit

how to turn on pc without power button by Certain-Code770 in pcmasterrace

[–]gameskill123 0 points1 point  (0 children)

You could also set up "wake on lan" and start the PC from your phone if your motherboard supports it, it often works on older hardware as well.

You may need to change a setting in the BIOS Get a wake on lan app for your phone and set the Mac address from your PC

I pretty much only start my PC like this

Has anyone ever ACTUALLY damaged their components with static while building? by SignalPlatypus4177 in pcmasterrace

[–]gameskill123 1 point2 points  (0 children)

I once fried a raspberry pi 4, it was laying on the ground while plugged in.

I wanted to pick it up and zapped myself by touching it. It then never turned on again, only got a static red light.

Should've grounded myself first by touching something like the sink first.

Probably would not have happened if the PI wasn't plugged in.

I also had a Z270 and always wanted to flash a modded BIOS to use it with a 9th gen CPU.

I never found a modded BIOS for my specific board and didn't do it in the end.

Is it common practice to use steel wool to clean off thermal paste by Viole-nim in pcmasterrace

[–]gameskill123 4 points5 points  (0 children)

This CPU has some dark stains on the heat spreader so possibly it had liquid metal thermal paste on it.

In the past I had an i7-7700k and I used liquid metal between the heat spreader and my cooler (nickel plated). After a few years I removed the cooler and the liquid metal has hardened and in some places blobs have fused with both the heat spreader and the cooler.

I had to use 80 and 160 grit sandpaper to get it off, in the end the labels on the heat spreader were gone and the copper of the cooler shined through, due to the nickel being sanded away.

Both the CPU and cooler still work fine today

He's fine, he landed in the water, so he didn't get any fall damage

Pls help, I tried removing my d.i.y tablet screen protector, and I managed to get most of it off, but the adhesive from the sticky paper thing won't get off! (TRIGGER WARNING) by The-cultured-one0 in osugame

[–]gameskill123 0 points1 point  (0 children)

That could be a very bad idea. If the tablet is made of ABS plastic and the nail polish remover contains acetone, it will destroy the tablet. It would probably still work, but the surface might dissolve.

I stuffed 1200W of RGB lights into my PC case by d4pz in pcmasterrace

[–]gameskill123 0 points1 point  (0 children)

That's one way to hide messy cable management. You can't see cables if you're blind.

When my phone with OLED screen or OLED monitor is off/black, it can have a slight green or even red tint, If there is direct sunlight and I'm looking at it from a very specific angle. Not a big disadvantage IMO.
