You should be able to set things up to be able to call via wifi or text. Google Voice I think is free for personal use for calls in US. (I haven't set this up, so you probably ought to double...
Just wondering.
Are some of the available knob covers (I think that's what Gitzo is calling them) the right diameter, but the wrong height? If it's the right diameter, you can either have a small...
I thought Blackwings were good but expensive ($30/dozen). Try a "Mitsu-Bishi" 9850 HB lead and it writes smooooooth and only $8.50/dozen
on the Sharpener side I have found the T'GAAL ...
Google rotella motorcycle
Apparently it is a thing with motorcyclists
Those types of tanks have a shutoff valve that has the Schraeder valve built into it. You see the red thing around the Schraeder (fill valve). It twists to shutoff the air to the flex hose. ...
I use the key tags if they have a key loop. (I try to not get the ones with a keychain loop). The plastic key tags are available for ~$5 for 40-50 of them on Amazon. I have a couple that I bought...
You may want to see if someone can 3D print you a tray or liner that fits the space.
What I really need is a heated computer mouse. My office is about three doors down from an outside door, and when classes change the temperature drops 10 degrees (at least now when we are having this...
Is the LED a 75 watt LED or a 75 watt equivalent. Since folks know what a 75 watt incandescent bulb produces in terms of light the manufacturers have used "75 watt equivalent" terminology. The...
Sounds like an idea for an APP on an Apple Watch or other smart watch.

I’m not sure what we would call a mark that indicates where the post is coming from? :)
I don't know what the Ohio sales tax was but $7.72/$7.10 (transposing the 1 and the 7) gives about 8.7 %, the $1.93/$1.70 would be about 13% (which seems a bit high). Digit transposition in...
I have a much longer one in my office here. :D 510687
Femtosecond laser spectroscopist here (I know it's a bit slower than the attosecond stuff but...)
Attosecond is 10-18 seconds while femtosecond is 10-15 second
attosecond pulses are...
It looks like that is the "suspension" for the axle. If the rubber on the left side of the middle photo fails, the trailer "body" will drop to the ground. (or at least as near as I can figure).
Search youtube for squirrel trebuchets Launch them into your neighbor's yard :-)
Sounds like one more place to leak. Hard pass

Physical Chemistry Professor (and former autocross racer) here.
There is a lot of voodoo about nitrogen in tires. In normal auto tires, it won't make a lick of difference. In some specific...
If it is iron in the bowl, you may want to try a chelating agent (key-lating) like in Evap-o-Rust and see if it sequesters the iron.

The books probably aren't worth much. The folks on Amazon are fishing for folks with "One-Click" buying. I warn my students about that. One of the American Chemical Society Exam review books shows...

When a COVID night shift nurse creamed our limestone block mailbox coming home one morning from multiple shifts two summers ago, we replaced it with a mailcase locking mailbox. It has done well...
It might be easier to cast the router plane body, than a smoother body.
My favorite is a bottle of purified sand from the laboratory (it's used for packing columns for separations and such). Basically, if you followed the label warnings you wouldn't go near a beach,...
