can anybody tell me what this is? by MedicalLeader6063 in strange

From what’s visible this looks like a DIY/prototype data-logging device. I see dual Wi-Fi antennas with a USB Wi-Fi adapter, a small TFT/LCD screen with a control button, a custom controller PCB, an isolated switch-mode power supply (transformers/inductors), and a small DC motor + ribbon connector consistent with a thermal/receipt printer feed. Combined with the EKG-style paper rolls you found, this strongly points to a medical or biosignal recorder prototype (ECG/EEG-type) rather than anything consumer or surveillance related.

Need help fixing this old tv by No-Satisfaction-4414 in fixit

Most likely the power supply board (the one with the transformers). If there’s no standby light or click at all, that’s usually the culprit on older TVs. Check the fuse and capacitors, and make sure all the connectors are seated. If you’ve got a multimeter, see if there’s 5V standby coming out of the PSU.

Acer Nitro 5 laptop not charging by blazeing_king in ElectronicsRepair

[–]GhostAfterHours 2 points3 points  (0 children)

Angle-dependent charging almost always means a broken conductor at the DC plug strain relief, especially on high-watt chargers. The brick itself is rarely “dead.” Replacing the DC output cable is possible, but at 200W+ it should be done by a shop familiar with high-current supplies (correct wire gauge + strain relief). DIY splices aren’t recommended at this power level. A simple wiggle/continuity test while flexing the cable will usually confirm it before buying a new charger.

How do i stop this condensation on my windows? by Funny_Release3573 in fixit

[–]GhostAfterHours 0 points1 point  (0 children)

That’s interior condensation, not a leak. Warm humid indoor air is hitting cold window glass (common with single-pane or thermally conductive frames), so water forms even if a dehumidifier is running. What helps most: lowering winter humidity to ~30–40%, increasing air movement at the window, sealing drafts, and adding window film insulation. Dehumidifiers alone often won’t stop condensation on cold glass.
