I think if you suspend the artwork a few cm from the wall, it will trap a little more sound as well. I suspect you will need to cover a large fraction of the wall unless you are just trying to deaden the reflection directly behind a person. just curious, why inset into the wall ?

Reminds me of the Cutter John strips in Bloom County and The Academia Waltz years ago. Warp speed, Mr Spock !

Secondly, your immune system retains some response even if it has been longer than 6 months since you had that specific vaccine.

Each of the vaccines targets a slightly different portion of the spike protein. There was some evidence presented by studies for the US FDA that showed an increased effectiveness in preventing serious illness. Not huge, but an increase. I believe the specific comparison was between Pfizer and Moderna vaccines at the time.

Or even your 45 year old Thai wife ????

I would think twice about placing batteries and charging electronics under a stairway, particularly if that is the only way down from the second floor occupied space. batteries also release heat when charging and that heat needs to go somewhere so the batteries stay within operating limits.

Don’t forget surge protection (MOVs) on the AC feed to the property. Cheap insurance. Replace every decade or so or when the indicator light goes out.

And when it does go wrong with a closed kitchen tap, the bursting heater internal line or joint will spray whatever volume present in the unit of superheated water followed by hot water. Any flesh in the way of the water/steam mixture will get instant 2nd and 3rd degree burns. How likely depends on the details of the unit’s control design and built in safeties. That is what the thermal pressure relief valve guards against. Works the same for an ordinary tank type water heater with the only difference being the volume.

Three lightning strikes within 100 ft of my house in as many years convinced me of using supply MOVs + a set at each device. Won’t be adequate for a direct hit, but so far, so good. Probably about time to change out the one at the mains as it has been 10+ years.

Mine will do that in response to stress or randomly. My house builder had same thing that gradually became worse until he blacked out in the shower and was resuscitated with an adf shock. Two days later he was the proud owner of a pacemaker. Go see a cardiologist wherever you live and they may give you a monitor to wear for a month or two. The events usually pass quickly so by the time you get rigged up it is over, one way or the other, and without the monitor the doc won’t know what is going on for sure.

Here is a simple user test to determine how long the ups will allow the cameras + nvr to function. Get everything installed, charged up, and verified to work. Then, turn off power to the system and let the ups do its job. Start your timer. Note the duration when the system starts failing. Done.

At least there was a spot for a 3mm tip in the plastic case in the picture.

Yeah, yeah, i know . West meets East. Lol.

Find a licensed electrical engineer to design your system. Or possibly a master electrician from a reputable firm familiar with the code requirements.

What are the amps and number of phases/poles for the major devices ? Ovens in the US are typically hard wired ( no plug) , 2 120v phases, and require a separate breaker. Good idea to put microwave on dedicated circuit, 20 amp (US) as you don’t want to have two high current users on same circuit and trip the breaker repeatedly leading to a weak breaker over time. Dishwasher may pull 10-15 amps and is another candidate for a dedicated circuit. Other than that, i think our rule of thumb was no more than 6 plugs per breaker for typical low-moderate current plug in devices. Any plug within 6ft of water had to be gfci.. that being said, code may have changed and you should do some research in the local electric codes.

From what i could see of the tips, was the H3 too small and the 1/8 hex key , i assume on the cluster, also too small ?

Or a 3.2 mm Allen. That is a rare beast.

Forgot that. Now all we need is an inside caliper ….

Likely a 3.5 mm hex key socket given that it is between the two T sizes.
