I like watching the pros repairing electronics, it looks so easy when they change tiny component packages. #feelgoodfactor
Anyway, I have never heard of voltage injection before, they all do it, so I guess it must be standard?
NB: Lots of tips on purchasing expensive second hand hardware on this channel (some people even remove the GPU core and sell cards like that......)

I need help troubleshooting my network simulation. This simulation simulates simple network with a router and a client (both are jails). The router provides internet to client 1 through netgraph.

Setup:
1. Host-Router (Epair)
2. Router-Bridge-Client1 (NetGraph)

What were working:
1. Router can ping 1.1.1.1 (Internet Access)
2. Router can ping host gateway (192.168.200.1)
3. Router can ping client 1 (192.168.150.10)
4. Client 1 can ping the router (192.168.150.1)

What were not working:
1. Client 1 cannot ping 192.168.200.1
2. Client 1 cannot ping 1.1.1.1

What I have done:
1. Enabled gateway_enable in rc.conf
2. Configured all forwarding in sysctl
3. Create default route to 192.168.200.1

In case any kind fediverse #QMX owners would like to help troubleshoot my dead QMX+, I'm trying to get some interest in it on the #QRPLabs forum: groups.io/g/QRPLabs/topic/1144

Yes, I WAS trying some new power cabling I had just made and NO I didn't have it fused, but the BS170s don't seem to have fried, at least on visual inspection. It gave me a yellow/green screen of death and then would not power back on.

Any help greatly appreciated!

Just spent hours debugging what looked like an OpenTelemetry context detach error in my ADK + MCP setup. Went down rabbit holes trying to fix async redherring, cancel scopes, and tracing configs.

Plot twist: It was just a self-signed SSL cert on our staging server 🤦‍♂️

The real issue was buried 50 lines deep in the logs. Sometimes the loudest error isn't the root cause - it's just a symptom.

I'm having terrible difficulty getting a variety of apps on my Android phone to play custom notification sounds from wav or mp3 files. I can choose the relevant files as notifications sounds in the apps' internal settings menus, but I get either silence or the default notification sound when there's a notification. The files play successfully in my music player app. Anyone have any advice, please?
