This video of two hungry fawns feeding from their mother was taken looking out my living room window using a cell phone camera. We only mow grass around our house. The unmowed part has not seen a lawnmower since 1995. That's why it's popular with deer. Does like to drop their fawns on our...

These spam posts get moderated so fast that most people never see them. The moderators have a special button that deletes the post and permanently bans the spammer. I have not counted, but a rough estimate is a dozen or so "status update" posts per week. We have roughly 50 moderation...

Just ONCE, I wanted to see a post titled Status Update that was not a blatant, annoying spam post by a new member. So here it is. Today was a good day here in Northern Wisconsin. Fall colors are here, no mosquitos, no deer flies, and mild temperature, so my morning run was unusually nice...

Fall colors on the ATV trail less than 5 minute walk from my house. The colors are not quite at their peak. This is Northern Wisconsin, USA. Temperature 80 degrees F, light breeze, and cell phone camera.

I have been using LibreOffice for 10(?) years now. No problems with losing / exploding / crashing / failing documents. I only use their Writer and Calc. I think I used Impress once, successfully. I hated MS Office. I had to spend a day shutting off all their productivity killing features...

Search dashpots in McMaster-Carr. Dashpots are designed to slow something down for a soft landing. You will need some sort of bracket on your adaptor plate and another bracket on the fixed part of the assembly. If you sketch something up, and provide the drop distance and moving mass, we can...

I am slightly color blind, to the point where I can just barely pass an FAA 2nd class flight physical. That vision deficiency has been constant since my first flight physical over 50 years ago. I can only see PF hyperlinks when I have previous knowledge of their existence, and know exactly...

Yes. A reciprocating air compressor, like a steam engine, has a piston moving up and down in a cylinder. Air compressors need an air compressor head on the cylinder. An air compressor head has a pair of reed valves. One valve lets air in on the piston down stroke, the other valve lets the...

Some thoughts: When working on a difficult problem, I try for a mental state of relaxed alertness. When I start slipping away from that state, I stop, take a deep breath, slouch down, and exhale slowly. That usually gets me going again, although sometimes I need to do it two or three times...

Three consecutive photos of the neighbor's house. The first photo is from 2003. That house was originally built some time before 1984, probably in the 1950's or 1960's. The previous owners never built big fires, while the new owners built a big fire in the fireplace. No surprise what...

Due to liability concerns, we cannot help you. This needs at least a qualified electrician, and possibly an electrical engineer. This thread is closed.

How much faster? Is it 0.1%, 1%, or 10%? And how much forming was being done at each station? Does the paper say anything about the effect of scrubbing when the material being formed wraps around the forming rolls? One roll will tend to hold the material back, the opposite roll will tend...

1) What is RAS? 2) How does the APC work? Does it sense pressure, water level, flow, or what? 3) The APC photo shows two different cables and what appears to be some sort of connector. What are the inputs and outputs to each of those? 4) Where is the APC connected in the piping diagram...

Saw this on a business trip to Kentucky some years ago.

This little robin was the last one to leave the nest. An hour after this photo was taken this morning, it was gone. I put up the nesting platform to stop robins from building nests in that gutter. I take the nest down after the new birds leave. Sometimes another bird will come along and...
