Shock or vibration absorbing hammers

 

Maddison Wisconsin U




Fiskars isocore XXL 22oz 16"

Damping ratio from Stanley, handles only:


Stanley fatmax anti-vibe Xtreme

This is newer version which goes back to single forged steel body，and eliminates the hammer head bolt+resin, which is said the head loose after just weeks of use

I am a union carpenter and i purchased this hammer from Lowe’s. Used it for 3 months, i loved it great balance, very light, sinks nails wonderfully, magentic

 holder worked beautifully, great vibration reduction. But alas flawed design makes the head come loose. Amazon reviews are all the same. Even a coworker purchased one as well, same deal.

Toolguyd, amazon


Triple plastic injection (similar to sport shoes soles)

Fatmax Xtreme:



Toughbuilt 拓必得 shockstop 20oz ,22oz,24oz (two times or more expensive than 木井方/SATA）


木井方 low vibe(2017)手柄藏有減震彈珠







SATA has similar bolt and spring design(german patent?), but spring is hidden inside the body, not easily seen

Quick trial at shop，but the grip found too rigid, and hardly notice any shock absorption.

豬仔嘜 是fake,沒有彈弓/彈珠！！！

With fluid piston:





16 inch

Swinging a hammer can lead to  tendinitis in the elbow like that seen in “tennis elbow.” ， or carpel tunnel syndrome

Good grip, but only ~13 inch / 380 mm long

Tolsen 16oz 25271 13 inch

Kraftool 20182 600g too heavy in hand , not recommended 

Mytec 美科 一體 MC-1302 13 oz ok, AliExpress . Same as delixi?

Balance and good shock absorbing non slip grip is more important

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved  from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

    14 Oct 2020,  being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station.   The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station.  previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
