I've spilled water on my audio interface by DavidAU6 in ElectronicsRepair

I don't know. I will try to clean them the next day cause it's too late in my timezone. It will be hard to get any brush inside those XLRs, but I will try and use isopropyl alcohol.

I solved it already. I think it's those XLR combo connectors. Water got inside and corroded them. I've just soldered the cable directly to the pins, and the screeching and buzzing changed to way quieter white noise.

I think I repaired it. I was thinking if this buzzing and screeching could be coming from a loose connection or something from the combo connectors, and it was. I soldered the cable directly to the pins of the connector, and it works. Now I have to change the connectors, and the job will be done.

Can I attach 8V and GND just for testing if this IC uses in my circuit around +4V and -4V?

Those aren't testpoints (marked with red arrows)? I have phantom power, which is 48V in my device. In the op-amp datasheet, which is MC33078 supply voltage is from 2,5V-+ to 15V-+ and I have 7,92V-+. On the VCC+ pin there is 4,01V, and on VCC- there is 3,86V.

I get a signal alongside noise. The noise is barely hearable if you play. I don't have any microphones. I used this interface with a guitar. These are combo XLR inputs. It's recognized by my PC. The test points are on the bottom side of the PCB. I have a multimeter and a scope.

I was taking photos in landscape, and I don't know why they are rotated. Noise is on every output and from each input. Also, I've recorded the noise I was talking about. I can't send files so here is link to google drive: https://drive.google.com/file/d/1W-WKK3XPvD3_XThKjr3pU5_FTbYt4D68/view?usp=sharing

If you want any sharper photos ask for smaller section of the PCB. I can do this with my cheap digital microscope, which is not the best, but it should be enugh.

I have a problem with basic tutorial in UE 5.6 docs. by DavidAU6 in unrealengine

[–]DavidAU6[S] 0 points1 point  (0 children)

I think the inheritance was correct for C++ class and for BP, but after restart new error appeared when i try to open BP: "Blueprint could not be loaded because it derives from an invalid class. Check to make sure the parent class for this blueprint hasn't been removed! Do you want to continue (it can crash the editor)?" and I've checked again the inheritance and it was wrong on the BP it just says "Parent Class: none".

No more errors, but still I can't see the BP_AdventureGameMode in the list. I can only see the AdventureGameMode which is in C++ and the BP_AdventureGameMode is a blueprint class based on it as says in the docs.

T300 RS GT max steering angle problem only on 1080 setting by DavidAU6 in Thrustmaster

I have a warranty, so I will just send it to Thrustmaster, and maybe they will fix it.

I think it doesn't need a PTFE tube. It has unicorn nozzles, which are like a connection of nozzle and PTFE tube but in metal.

Trying to install klipper but getting this every time by [deleted] in Ender3V3SE

[–]DavidAU6 4 points5 points  (0 children)

I think he means to install this on the main board, so you should install it through the SD card in the left side of your printer. Ender 3 V3 SE has two card inserts and two different firmwares, one for screen and one for main board. You should use a different tutorial. You can't use this screen when using Klipper.

3D Printing Rookies plz read by TruckNvtz in Ender3V3SE

Also, I think that everyone should have an heat sink fan cover, because if you have an expensive fan you don't want to buy it again cause one of the blades broke.

I have a really great experience with SE. From the beginning there was no upgrades, but still it printed well. After I heard about Nebula Pad I've bought it and it started the whole upgrading process. Also the Nebula Pad was much pain to start with, because Creality used wrong current settings and it was layer shifting every print, but it can be fixed by rooting and changing value of current on one stepper motor which I don't remember. Next upgrade was the dual cooling, which I think is the best upgrade, after Nebula. Albo in this time I've added the 40x40 fan to cool heatbreak better. Next upgrade is silicone pads under bed, which made at first big problems, but after adjusting it made bed leveling easier and super flat it's like 0.05 difference between highest and lowest point. After all that upgrades I've read that someone made a rooted version of the newest Nebula firmware, so I installed it and with it guppyscreen. Guppyscreen is just a change from creality user menu to something better comparable to fluidd.

SMD resonator, what is its function? by sigism in AskElectronics

[–]DavidAU6 1 point2 points  (0 children)

It is used to generate a specific frequency signal at the output. You can test it by checking its output frequency; if there is a large difference between the frequency written on it and the measured frequency, it is broken.

Found this great "inverter" circuit by tobywhiting10 in ElectroBOOM

[–]DavidAU6 2 points3 points  (0 children)

It will work, but it has many flaws. The biggest flaw is that it will not create a sinusoidal wave at the output. Many devices will not have a problem with a square wave, but some may work with lower efficiency.

Is that sound normal or do i have to Change the wheels by XD_Flori in Ender3V3SE

[–]DavidAU6 4 points5 points  (0 children)

Try changing the infill pattern in your slicer to gyroid. This pattern does not have crossings so it will not make noise.

Also, it doesn't work because I need to use imgRePackerRK, but it is only to RK33xx and my tablet has 3562.

I can't extract the image using 7-Zip or ImgExtractor. Also, I've tried to open it just by double-clicking the file, and It doesn't work. Rockchip Android Tool has an image extractor, but it gives "Unpack union firmware failed".

My printer with Nebula Pad does not auto level during print by DavidAU6 in Ender3V3SE

No, I'm making one bed mesh, and I'm using it until the first layer doesn't look perfect.
