Whole-house surge protector

s-surge-protector-2010-04-10-1.JPG

I finally have a whole-house surge protector, something I’ve wanted for a long time. It’s possible to buy these things and have an electrician install it, but my electric company offers them for $9.95 a month, with installation, and a warranty, included.

The surge protector installs under the meter. It took the technician only a couple of minutes to install it. The warranty will pay for the repair or replacement of anything damaged by lightning (or any kind of power surge) that gets through this surge protector. The warranty covers each damaged device for up to $5,000, or a total of up to $50,000 per incident. One of the advantages of a whole-house surge protector is that it can protect the big stuff such as the heat pump, refrigerator, washing machine, etc. It’s a good idea to keep the small surge protector installed at computers, etc., to give them double protection.

I hope this makes me feel a little more secure during the summer lightning storms. I know how much damage lightning can do…

Radio in the age of Twitter?

The map shows the locations of the stations whose beacons I heard (or who heard mine) Friday afternoon.

National Public Radio had a story this week on how ham radio is growing in the age of Twitter. Not only is ham radio very much alive, hams are always figuring out new things to do with radio and computers.

I recently discovered a new digital communications mode invented by hams called WSPR — Weak Signal Propagation Reporter. The idea is to have a computer-controlled radio listen for (and transmit) low-power digital beacons on certain frequencies. The power could be as low as 1 watt. But because the data carried on this signal is intentionally transmitted at such a slow speed, the signal is very reliable, even a weak signal in the presence of noise. It takes almost two minutes to transmit only enough data to give the identity of the transmitting station, its location, and the amount of power used. Error correction is used to make copying the signal more reliable. So a tiny amount of power goes a long way.

The computer completely automates the process, listening and periodically transmitting. Every two minutes, it tells you whose beacons you heard. The computer also uploads this list of who it heard to a web site where all the data is collected. On this web site, you can see a map that shows who can hear whom all over the world.

Modern ham radios, by the way, have interfaces that allow them to be controlled by computers. Computer programs also can create audio to send to the transmitter, and interpret audio from the receiver. This is how computers encode and deocode digital signals that are transmitted as sound on the radio.

Using 3 watts of power, my beacon was heard from New England to California. I raised the power to 30 watts for only two beacon transmissions, and I was heard across the Atlantic, by DK3SML in Germany; G8BKE in England; IV3DXW in Italy; PA3MET in the Netherlands; and 4X1RF in Israel. This was on a frequency of 10.140 Mhz.

Some hams like to work with big antennas on tall towers, and power amplifiers. I find it more challenging (not to mention less expensive) to limit myself to 100 watts and only such antennas as I can hide in my attic. California on 3 watts and Israel on 30 watts — not bad.

Part of what’s fascinating about WSPR mode is that it’s an easy way to test your radio, your antenna, and radio propagation conditions. Leave the computer and radio alone for an hour or two to transmit and receive beacons, then have a look at the list of who heard whom. It answers the question “How far can my signal be heard?”

Google recipe books

Coconut custard pie

More and more, when I Google for recipes, I get recipes from published cookbooks on Google Books. I’ve had it in my head for a while to make a coconut custard pie. My usual reference for standard recipes is the 1943 edition of Irma Rombauer’s Joy of Cooking, but Rombauer’s recipe didn’t fit my ingredients. I wanted a recipe that uses dried, unsweetened coconut. I found such a recipe at Google books, in the cookbook The Dessert Bible.

I only make things like this when I have company. My mother is visiting. We finished off the chocolate apple sauce cake I made on Saturday, and the coconut custard pie was next on the list of dessert recipes I wanted to try.

Banana nutmeg smoothie

The temperature here yesterday got up to 85F. So it’s out with the hot drinks, in with the cold.

I have become addicted to banana nutmeg smoothies. I make them in a blender with soy milk and cashew nuts. Cashew pieces were the cheapest nuts yesterday in the Whole Foods bulk department, at $4.69 a pound. This is a nice, easy way to eat more nuts, and at a decent price.

Put half a cup of raw cashews or cashew pieces into the blender. Add soy milk to make 2 cups. Whiz for a minute or more. Add a banana, two tablespoons or so of honey, a quarter of a teaspoon of vanilla extract, and half a teaspoon or so of ground nutmeg. Whiz again for a minute or more.

It’s as rich as eggnog and a hundred times healthier.

A walk to the mailbox, early evening

I have to walk half a mile to my mailbox. The mail carrier doesn’t come down the unpaved private road I live on. I took my camera with me when I went to pick up the mail this evening.

Above: pear trees in full bloom. I wish I could say they’re mine, but the trees line the road beside a neighbor’s horse pasture, up the road from my house.

I’m not sure what this is. They seem too tiny to be violets. Update: My sister emailed to say that they are bluets.

I’d often wondered why a neighbor strung fairy lights along a pasture fence. Now I know. It was an experiment in keeping the deer out. I doubt that it worked.

Second attempt at sourdough bread: C+

a-sourdough-2010-03-24-1.JPG

My second baking of sourdough bread today was considerably improved. I’m starting — starting — to get a feel for sourdough. But I think that it’s going to take some time to become confident and skillful with sourdough. Still, today’s bread had a better balance of flour and water. The crust was good. The starter is becoming more sour.

I’ve got to stop all this breadmaking, lest I start gaining weight. But still, I never buy bread. There’s no bread in the house unless I bake it myself. I have found that when I start getting bored with my own cooking, one sure way to perk up my interest is to make hot biscuits. Whole-wheat biscuits are completely decent, but proper Southern biscuits can only be made with white (that is, unbleached) flour. Olive oil works, but truly proper biscuits require shortening. The biscuits above were an experiment with palm oil, which I had never used before. The palm oil and unbleached King Arthur flour made fantastic, melt-in-your-mouth biscuits.

I have a lot of doubts about whether palm oil is a good thing. I bought it primarily for pie crusts. Used in moderation, I suppose it’s not so bad. And it’s certainly better than a hydrogenated shortening such as Crisco, which I would never use, ever, under any circumstances. The liver and veins simply don’t know what to do with hydrogenated fats. Palm oil, at least, is in a natural form that chemists haven’t tampered with. It has been used in the tropics for thousands of years.

Here’s a link to my previous post on sourdough.

Spectrum sells its refined palm oil as vegetable shortening. It’s white. Unrefined palm oil is red and contains a lot of carotene, and therefore vitamin A.

First attempt at sourdough bread: D-

So flat! Big mistake…

I couldn’t wait to try out my 7-day-old home-cultured sourdough starter. It’s probably a miracle that I even got bread that rose, and was edible. I ate it, for sure, with spinach salad, Stilton, and a slosh of chardonnay. But I have two big criticisms of my first effort.

1. The dough was too wet. I’ve been working on making breads with wetter dough that are less kneaded and more coarse and bubbly. But I think I took that too far. The dough needs to be dry and stiff enough to hold a proper boule shape. My dough did double, though, within a couple of hours. Something is growing in there.

2. Though the bread did not taste at all yeasty, it also didn’t have much of a sourdough taste. My guess is that the problem primarily is the youth of my starter. I’m hoping that, as the starter matures, the lactobacillus bacteria will get a stronger foothold against the yeast, producing more lactic acid in the dough and hence a sourer taste. There may also be tricks I need to learn about how long to let the dough rise, when to feed the starter before I make the dough, and so on. This is something I don’t fully understand yet.

This is clear: Making sourdough bread is a fairly different set of skills than making bread with commercial dry yeast. I think I’ve also learned already that making sourdough bread requires more judgment and a greater understanding of the biology and techniques of breadmaking. Sourdough bread takes longer and rises slower. There are more variables, more things that might go wrong and that the experienced baker must work around or compensate for.

Oh well. One’s gotta start somewhere. But ultimately I want to learn to bake a smart but peasanty sourdough loaf that will be the signature bread of Acorn Abbey. The bread contains nothing but King Arthur whole wheat flour and water. There is no oil, except to coat the pan. Some time ago, I stopped even putting salt in bread, unless company is coming.
