A Month for Disaster

There is a meme running around that relates all too well at the moment…

Smoke Over Waikoloa

Worst month ever!
What do you mean this is only the 1st?

Anonymous social media meme

This month is only four days old and we are quite ready to agree with whomever coined that meme.

Sunday, August first started out peaceful enough. I was looking forward to a relaxing day with a few chores about the house. The only nagging worry was keeping tabs on the large brushfire raging towards Waimea, though it was many miles away. As the winds picked up this worry also intensified, to where I had to the local emergency radio feed streaming on the computer speakers.

When the fragmentary radio chatter from the fire units indicated that the fire had jumped Highway 130 I knew what was coming next… An evacuation of Waikoloa Village.

A Walk Along the Shore

A series of very low tides had the lab gals looking to do some collection. Where? Right out in front of the office. With a “meeting” scheduled on the company calendar we went for a walk along the shoreline.

Aside from a morning sharing knowledge about sea life we did indeed find several specimens of Asparagopsis taxiformis to collect.

A Gas Modulator

The usual drill… A problem that can be solved by a bit of circuitry. In this case the gals in the lab were having trouble controlling the mix of gas to their cultures. They needed to feed much less CO2 to the mix, where the off-the-shelf flow gauges and needle valves became difficult to use much under one liter-per-minute.

Gas Modulator
A controller to modulate CO2 into a laboratory gas mix

Simple solution… Build a gas modulator, something that could turn on the gas some percent of the time, allowing easy control of small amounts of CO2 to the mix. A timer and a gas solenoid… Easy.

There is nothing particularly interesting about the circuitry. A seven segment display, a few switches, and a power transistor to control an external solenoid. All very basic. It is the controller that is new, at least for me. An Arduino provides the programmable part of this project.

The Skills of Living

Owning a home is expensive as maintaining a house demands constant effort and expense. On the other hand owning a home is vastly cheaper if you can do many of your own repairs.

This comes to mind as I have recently encountered a couple folks who had no idea how to perform simple tasks like jumping a car or very basic household maintenance. Having grown up with tools in-hand this is a concept I have difficulty with. How do you get by? Do you always call a repairman or a tow truck?

One of these people is the tenant of a friend. Since Tom is no longer on island he sometimes asks me to look in on his old house, now a rental, just a few blocks away. A few weeks ago I got a call that the garage door was stuck open. Sure enough a broken belt on the garage door opener, I texted Tom and he arranged for a repairman a couple days later. In the meantime the lady renting did not understand why it did not work despite a drive belt hanging down in the middle of the garage. She had no idea how to even open or close the door without the garage door opener.

Contrasting this are the repairs I have done over this last weekend… Last week our garage door came to a grinding halt partially open. A loud clattering announced it would no longer move.
