Primitive Technology: Water powered hammer

Various techniques used to build a water-powered hammer or “monjolo”.

I like the technique he uses to bore the hole in the log and make the trough: hot coal, blow pipe to make it hot, clay to protect the edges and direct the burning.

The key is finding out where the balance point of a log is (might not be the center, logs taper) after gouging out the water-catching trough on the back side.

As the trough fills with water it tips the log and spills the water all at once and the log’s other end falls.

Many different technologies and ideas involved in this brilliant machine. No doubt it took quite a bit of trial and error to get it right.

I’ve seen similar pieces of technology in Japanese gardens (in Japan and in Los Angeles) called Shishi-odoshi.

There are many more of these great videos at the Primitive Technology site and for those who prefer, he has a Primitive Technology YouTube Channel.

Shadow selfie on Salmon Kill bridge

Shadow selfie on Salmon Kill bridge

Salmon Kill Brook, Lime Rock, Connecticut.

Driving home from hiking today I stopped on a bridge I drive across a lot. I always see a very nice waterfall as I drive past so figured I’d try a shot of it. Unfortunately, the waterfall got blown out, all the white was just too far gone to pull back.

But, I did catch my own shadow on the water down stream of the waterfall and between the fence and my shadow and the rocks underneath the surface doing nice things with the light, I thought it was an interesting image.

Bubbles in motion

Bubbles

New York, Connecticut border south of Kent, Connecticut on the Appalachian Trail. This small stream that was a great provider of ice shots a few months ago is now a great provider of foam/bubble shots.

I returned to the same spot and lo and behold, a similar bubble island was spinning under a small drop. A lot more movement this day but sometimes movement is good; I like the movement in the individual bubbles although didn’t see it until I got home and looked at the images on my computer.

This little “bubble island” was under a small waterfall and was just spinning around. I wasn’t sure if any of the 20 or so shots I took of it would work out but I liked many as they each show a different kind of detail of the bubbles and the debris underneath.
