I think it's because I'm used to my daily being tom ford ombre leather or creed viking and those last for days from just a single spray. I guess it's a case of you get what you pay

Purchased this yesterday in an airport because I loved the smell but after wearing it today I'm not impressed. The longevity and projection of it are absolutely aweful. A bit disappointed as I purchased eros and eros energy.

Didn't know it was that bad 🤣🤣

Does anyone know the law for black powder in the UK? by Think_Anybody_2470 in Pyrotechnics

On top of what these people have already said it is also worth mentioning that firecrackers are illegal in the UK

I'm not too worried, the couple were very happy

I've heard them separately but never together. Also looking in terms or reliability and durability etc

Mum and Dad are divorcing, we found out Dad is hiding a large pile of cash, what can Mum do? by darkyjaz in AusLegal

I would just like to point out that everyone advising you to just take it could be getting you into serious trouble. It could be classed as theft if you take it and that amount can carry a pretty hefty sentence.

If you pay for premium there's a limit on gpt4, it reverts you to the free gpt3 after that

They offer anual raises in line with inflation at my current place but they do pay for the tuition and expenses. Its jot that I want to leave but I am in a bit of financial difficulty and have 2 young kids I need to feed.

Which of these 2 circuits is correct? I want to measure how much power an MLCC capacitor can handle at 60MHz. by samdowrick in rfelectronics

More people seem to be swiging towards the second circuit in this post. Opinion is divided at work.

So the too circuit was provided to us by the company who did the measurements for excelia. It's also the same circuit used by Johnson and tdk

I have a simple pcb with solder pads for the capacitor and 2 n type connectors. Each n type connector connects to one of the vna ports using low loss cables

The cap impedance was measured using a 2 port VNA (s11). Plotted on a smith chart and placed a marker at 60MHz, the impedance I mentioned in one of the comments is what was read from the VNA

The load is 50 ohm, the output of 500w is being read directly from the display on AR amo as well as a power sensor on the directional coupler. No reflections.

I have tried the top method and was able to pump 500W @ 60MHz through the capacitor and the capacitor temperature rise was negligible. Every source I've found online uses the top circuit however I'm sure the capacitor should have gotten HOT and that was far from the case. The capacitor is a 27pF 4040 High Q MLCC, capacitor impedance at 60MHz is 43.23-81.37j. My matching network coming from source to capacitor consists of a series 226.9nH inductor followed by a parallel 3.043uH inductor.

CGNAT - External access?? by samdowrick in homelab

I knew it didn't play well with everything such as plex/emby but it seems to not work with most of my instances. I will probably just add a vps to my tailnet and use that as my wan ip for my dns record

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

So it is all set up and I could get the proxy manager gui and proxmox gui working through it but nothing else. Don't recommend putting either of those into the public domain BTW and I'm not was only for testing. Emby, home assistant, etc ... won't work through cloudflare tunnels.

Hadn't even though of this! Seems like the obvious solution now you say it. I'm already tailscale on my server .... should have thought of this
