Softsoap Dispenser Lasts & Lasts

July 16, 2013

Softsoap DispenserThis liquid soap dispenser is sold as a single-use, throwaway when empty product. Since it was working fine when it ran empty and could easily be refilled (Ivory liquid soap, 48 oz. bulk, around $3.50), that’s what we did. It has been working fine for 4 years!! It’s not perfect–there is always 1/2 to 1 oz. of soap on the bottom that won’t pump out.

What is more troubling is that they don’t promote (or at least mention on the label) that this product can be refilled. It’s a shame to waste the plastic bottle and pump after only 7 oz of soap. It’s also expensive when you compare throwaway vs. refill.

Voyager Spacecraft

April, 2013

The Voyager 1 Spacecraft, launched by NASA on Sept. 5, 1977, is nearing the edge of our solar system. It has traveled over 18 billion kilometers, and continues to function as designed. This is a case where quality exceeded expectations.

The Voyagers (1 & 2) were designed to pass by Saturn, Jupiter, Neptune, and Uranus during the first 10 years after launch. If all went well, they would eventually end up leaving the solar system (heliopause). Thirty five years after launch, all is going well–Voyager has reached the heliopause, and it’s three large radioisotope thermoelectric power generators (RTGs) should produce useful power through 2025. Here is a gif animation of Voyager 1 near the edge:

Voyager is somewhere in the boundary area.

Mars Rover “Opportunity”

UPDATE: Oct. 2, 2018
Opportunity is communicating with earth and is charging it’s batteries after shutdown in June 2018, due to heavy dust storms. Here is a link to the NASA webpage with updates.

The goal for each rover was to be operational for 90 Martian Solar Days or “sols” (or approx. 92 earth days). A mean Martian solar day, or “sol”, is 24 hours, 39 minutes, 35.244 seconds. Spirit was launched June 10, 2003, landed on Mars January 4, 2004, and was active until January 6, 2010 when it became stuck in soft soil. It was shutdown March 22, 2010.

Opportunity was launched from Earth on July 7, 2003, and landed on Meridiani Planum on January 25, 2004. Still active in 2012, Opportunity has lasted 30x longer than the planned duration of activity.

Code-a-Phone Answering Machine

August 2012

This gem of electro-mechanical design was in service for 27 years, from 1985 through 2012! It didn’t break, but was disconnected this year due to the many robo-calls that were filling up it’s memory. With  occasional cleaning and tape cassette replacement, it performed flawlessly.

Simple, functional, with non-volatile tape messaging.
