Patience, a 9’ pry lever, some iron pipe for rollers, and a stack of 2x6 cut offs will handle moving pretty much any machine around the shop. (A pry lever is a long lever with a pair of small sturdy wheels to act as a fulcrum and a short me

I plant a small field at the end of my parking lot in grain; wheat, oats, or barley. It started as a way to replace the weeds the previous owner let be, but over the years it has become its own challenge. The progress from bare soil to gree

Or contact your local ice sculpture company. They have special ice freezers for making large, clear blocks of ice. But I’d much rather make an ice lens on an arctic beach from an iceberg than walk a couple blocks and get an off cut from the

Malaysia has no track record of significant domestic ethanol production, so it is unclear where the ethanol blended with the U.S. product originates. I wonder if they sell the tanker of blended ethanol to the Chinese buyer, offload 60% of

EEPoE is new to me: Microsemi's exclusive EEPoE technology cuts the power losses on Ethernet cables by 50%, through the utilization of all the copper available on cable when a Microsemi EEPoE PSE IC or Midspan is used. It is 100% comp

In the context of a Supercharger the critical metric would probably be cost per charge/discharge cycle for a given capacity bank. While a car probable averages a fraction of a charge cycle per day, a busy supercharger might be on the o

There is plenty of demand for short range commercial pickup trucks. Think of "on campus" maintenance vehicles. You need to tow equipment trailers, haul tools and bulk items, but you don't put many miles on them. A trip to the

If I’m reading the charts right in https://arxiv.org/pdf/1307.7343.pdf the the salts they are documenting are in the range of whole milk, cold water, and hot water. But there is no better than a 50-50 chance that I’m i

Earnshaw's Theorem does not apply to moving magnets. A spinning magnetic disc can levitate over static magnets. As much as I'm liking sounding like I have a clue about the theorem… my brother had a Levitron and I played with it.

In the 90s we used to use purple sunscreen on the kids which then turned clear after exposure to air. It made it easy to get a complete, uniform coating. I never see that for sale anymore, just waiting for the news why.

If you look at disability rates by county you will find that people on disability tend to live in low cost of living counties. For instance, my daughter's county has 15% of the population with employment disability and an average incom

The centerpiece case for the story is an odd one to support the assertion. The article vilifies the evil doctors who carelessly churn through disability claims, but it also notes that the doctor for the article's centerpiece was not pr

The PRUs run at 200MHz. So that is something like a 250ns latency, so four times faster than an Apple ][ for RAM access. (Maybe ten times faster, I think all the memory instructions took two cycles or more.)
