Electricity Usage Update: 12% reduction

I reduced my electricity consumption by 12% this year (2007) versus last year (2006). I consumed an average of 110 KWH of electricity per month during 2007, as shown on the chart below:

Now that I've done all the cheap and easy things to reduce consumption, and so I don't know if I can save so much more next year. I've done everything I could easily pursue, including:

replacing old fashioned light bulbs with CFLs
turning of my computer equipment, lights, and other stuff when it's not in active use
reducing equipment that consumes lots when doing nothing (such as my old VCR)
adjusting my fridge properly

So, any ideas of what else I can do? Since I live in an apartment, I can't readily upgrade my fridge (which averages around 50 watts). I could buy a new LCD TV, but I'm not much of a TV watcher so that doesn't seem like it'd be a good move.

Fixing a SodaStream Jet, part 1: Disassembly Guide

I've had my SodaStream Jet for years, and once in a while something has gone wrong. Disassembly is the first step to repair. Start with this article to see how to disassemble the SodaStream, and then once you have that down, scroll through my other articles to see how I repaired specfic SodaStream problems. SodaStream Jet Disassembly Guide Tools Required Flat head screwdriver Phillips head screwdriver 1. Remove the Carbonator. Duh. 2. Remove the black panel lever The front big black tilt lever needs to be removed first. Removing this panel is tricky, but it isn't impossible. Looking up at the bottom of the black panel, there are two tabs, one on the left and one on the right. These tabs fully secure the panel in place. The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way. Note in the pictures how I approach these tabs with my screwdriver. I usually release the left side first, and then I release ...

Fixing my Wahl 9918 Groomsman Beard and Mustache Trimmer

Not everyone would bother repairing a $25 beard trimmer, but why not fix something for under $5 instead of spending another $25? My Wahl 9918 Groomsman Beard and Mustache Trimmer has admirably performed its beauty duty for many years, but the time came when the battery just wasn't holding a charge any more. Most people would just put the trimmer in the trash and buy a new one, but I figured I could repair my otherwise excellent Wahl and save some money. In fact, even high priced trimmer and rotary shaver brands, like Norelco and Remington, can be easily repaired using a process similar to the one I used to fix my Wahl. Read on to find out how. I opened up the Wahl by popping off the black plastic faceplate with a tiny flathead screwdriver, which revealed two screws. By removing the two screws I was able to easily open up the unit, revealing the guts of the device. Backplate off, Revealing the screws The internals are rather simple: a motor, a...

Sodastream Carbonator Leakage, Usage, and Weight

SodaStream 60L "Carbonator" CO2 cylinders have a specific weight when empty, plus about 410 or so grams for the CO2 they should have when they're "full". A little while ago I went to buy a replacement Carbonator from my local hardware store. The dealer pulled a new Carbonator out of the box and sensed it was lighter than usual. He put the "light" Carbonator in the "empty" pile and sold me a different one. At that moment I concluded that it would be smart of me to weigh both new and empty SodaStream carbonators. Here are the results. Weighing a SodaStream Carbonator - for both Science and Consumer Protection. The dealer told me that sometimes the carbonators leak after they leave the SodaStream filling facility. That means there could be an opportunity for customers like me to get ripped off! The SodaStream cylinders I buy claim to have a net product weight of 410 grams - and that means that a full Soda Stream Carbonator shou...

Excellent DD-WRT Router for Me: Netgear WNDR3400 / N600

My WiFi performance was suffering, and so I decided to do something about it and upgrade my router. When I say my WiFi performance was suffering, I really mean it: I live in a large high-rise apartment building and there are 100+ WiFi access points visible from my home office. All of the contentious traffic was severely curtailing my WiFi reliability. I was lucky to get 1 Mbit/second throughput. Sometimes I was lucky to stay connected even with my WiFi router in the same room. I decided it was time to go for 5 GHz, which is a WiFi band which is used less frequently and which has a tougher time traversing walls. And of course I wanted DD-WRT support. The set of features I was looking for included: Trouble-free DD-WRT support 5 GHz 802.11n Support Simultaneous dual band capability Inexpensive. Maybe even cheap. For me this means under $50. Under $35 is even better! It sounds like an easy task to bring all this together: A...

Fix a Lightning Cable with Heat Shrink Tubing

We've all seen a Lightning cable that has started to fall apart. They get used every day, and after enough tugs and yanks on your iPhone, they start to fray. I've seen a lot of these frayed cables, so I've started to fix them before they break with heat shrink tube. I get my heat shrink on Amazon, like this handy and inexpensive pack. I prefer the heat shrink tubes without internal glue - it has higher flexibility and a smaller outside diameter once shrunk. Heat Shrink Tubing on an Old, Frayed Lightning Cable In the photo here, you'll see that I slid on a 1.25 inch length of heat shrink over the lighting connector, and then shrunk it into place. I chose a diameter that just barely fits over the lightning connector. In all, it took about 60 seconds to perform this repair. Warning: the white plastic of the lightning cable has a pretty low melting point. It seems to start to melt at about 125°C (or about 250°F), which is the same temperatur...

Thanksgiving Centerpiece (or, fun with paper mache)

Every year, one person in my family is assigned to make a special thanksgiving day centerpiece for the dinner table. This year I was assigned to make something. Fulfilling my obligation, I have created a paper mache Turkey, the center of the American thanksgiving celebration. Read on to see how to make this Thanksgiving Centerpiece Turkey, the official Pilgrim Turkey of Thanksgiving. Gobble Gobble! You can make me too! Strangely, most people don't know the story of how Thanksgiving became synonymous with turkey. But first, maybe you'll want to know to build this handsome fellow... Building the Turkey I started with a couple small balloons, some coat hanger wire, and masking tape. I formed the body and head with the balloons and taped them together. I bent the coat hanger wire to form the beak and legs/feet. Some needle nose pliers helped me bend the wire. Balloons, tape and wire. Note that I taped the feet to my work surface. The beak frame. I drew a face on the "h...
