Musical Reeds to measure RPM

This old tachometer uses music box type reeds to measure motor RPM without electricity. It's more useful than a digital Tach because it shows you resonant frequencies and can be used to check hammer and reciprocal speeds too.

This is a pretty neat device, after watching this video this weekend. They still make them but they are enormously expensive due to the limited demand and the cost of manufacture.

Technology Connections – Fans; High is next to Off on purpose

I've been woefully uneducated about the different types of electric motors and this got me reading and thinking about the different versions of this technology and how IGBTs and microprocessors using variable frequency drives have really changed things over the years.

Coleman Screened Canopy Tent Review 10×10

This is the tent I ultimately ended up deciding to buy for camping. This way I can have a sheltered place to cook and prepare meals and read a book on buggy or drizzly days. I also got a lantern post that I can put my propane lantern on and use in the tent as an alternative to hanging it on a cable at camp.

Planet of the Humans | Full Documentary | Directed by Jeff Gibbs

Michael Moore presents Planet of the Humans, a documentary that dares to say what no one else will this Earth Day β€” that we are losing the battle to stop climate change on planet earth because we are following leaders who have taken us down the wrong road β€” selling out the green movement to wealthy interests and corporate America. This film is the wake-up call to the reality we are afraid to face: that in the midst of a human-caused extinction event, the environmental movement’s answer is to push for techno-fixes and band-aids. It's too little, too late.

There is a lot of truth in this film - as much as people want to denounce it. Green energy isn't as green as it's proponents make it seem. Before you reject the film, I encourage you to catch the film in it's entirety and give it a lot of thought.
