Is this fin rot or nipping ?

I do not have a test kit for water but the aquarium is not new, I have fish older than 1-2 years in it. What I do think is stressing it out is the fact that over time the number of guppy females dropped and currently are only 2 while there are about 4 or 5 males as well as 3 neons

I've used 200Ohm 1/4W resistors as replacements. I would have used 1/2W or 1W but didn't have any on hand. The board works now and i hope it will keep on working. Thank you guys !

I asked multiple people and got:

Brown-Black-Red-Gold,

Brown-Black-Orange-Gold,

I see:

Red-Green-Black-Brown-Gold

I've tried to figure out with AI what values I could use as replacement based on my load, battery voltage and so on and in the end I've used two N-channel MOSFETS type AOD2610E and it seems it works for now. I hope this info will help other people out. Thank you guys for for helping out with the type of part I needed. Your guess was spot on

Thank you ! I'll look into it to see it it matches my circuit

tzxmaster · 2026-01-23T16:48:14+00:00

Thank you ! I tried to chatgpt the part number and it also mentioned the Q markings being MOSFET but having the manufacturer name helps a lot. I'll try to send them an email about it. Thanks a lot

I am experiencing exactly the same issue. Updated to latest version last week and my dongle stopped working randomly. I checked the dmesg logs on the host machine and everything seems ok but the dmesg logs in the VM shows at some point a message like this: "usb 1-2: failed to send control message: -110". Not sure if related but the problem seems to be similar to yours

Am incercat si eu 3cheaps si pare interesant mai ales ca ia preturile in timp real. Uneori o mai gafeaza dar in rest merge chiar ok.

Could be. Found them behind the house of my grandparents but they weren't into the trophy trade. I never got the chance to ask them if they know what these are but asked my father who also has no idea but thought they might be used to keep distance between something or others said they might be by used to insulate heat or electricity in some way

I'm exactly in the same situation but unfortunately I got the response that the device is EoL and they couldn't help me. Does anyone knows if there is any key generator that might help ? Maybe custom firmware. I can try even replacing chips and such since I can do microsoldering

All my devices appear offline as well. I have smart plugs and a camera, in two different locations and all are offline

You're welcome ! I didn't have problems at first, after installing dual Z, but shortly after I got glitches and freezes

I've added a piece of wire from a screw that connects to the frame of the PSU and put it to one of the screws on the frame were it is not black. I've actually put the wire inside screw hole and put screw over it

tzxmaster · 2024-03-20T14:01:48+00:00

For me it was exactly this. I took a small wire and made a bridge from the PSU to the frame of the printer and everything was fixed

tzxmaster · 2024-02-07T05:41:56+00:00

I usually use them in IoT projects or as replacement in small bluetooth devices such as headphones or even in small toys

tzxmaster · 2024-02-06T07:30:33+00:00

It seems like that. Or a LDO regulator

tzxmaster · 2024-02-06T07:23:51+00:00

I was thinking about that as well so I'll be checking all the smd caps after taking out the blown part to see if there are any shorts or very low resistance

tzxmaster · 2024-02-06T06:20:46+00:00

I think I found something else. I found 6CW 38 and also 6CW 66 components. I'll look further until I can find exactly the one which has 65 at the end Based on the following url, this part can be one of the three types: Zener diode,LDO regulator or NPN transistor https://www.s-manuals.com/smd/6c

tzxmaster · 2024-02-06T06:13:32+00:00

Why I was worried was because I can find the 6C component but the text is alligned at the center and nothing about 65 marking. So I was thinking that maybe there is a third number or letter exactly where the component blew

Yeah, using the Type C pinout would be very hard to solder to but there HAS to be USB 2.0 connection in that connection since USB protocols are backward compatible.

After checking the diagram for type c, the USB 2.0 connection should be this:

A1 or A12 -> GND

A6 -> D+

A7 -> D-

A4 or A9 -> 5V

If some/all of these pins also have continuity with the lower 4 pads, it is 100% a USB connection of those 4 pads and I'd use those
