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.

The Trick to Properly Fixing the Rubber Feet of a MacBook Pro

A black rubber foot of my trusty old MacBook Pro finally broke off, and I didn't like how it made the laptop wobbly. A fix was needed, and quick! First I bought some replacement feet, the kind that just stick on. These feet are nice because there is no need open up the machine to fix a broken foot. They're very inexpensive, and the ones I bought have adhesive tape already applied - just peal and stick. I bought feet like the ones found here. I have read many complaints about how the adhesive doesn't stick, but I think that's because people don't know the two tricks required to get the new feet to stick properly. New Feet to replace a lost Foot Important Trick 1: Make sure to remove all remnants of the old foot - including the pieces in the hole. My factory-installed foot was attached both mechanically and with adhesive, but when the old foot sheared off, some pieces of the old foot remained in the hole. Those plastic bits would h...

Canon SD890 Review

My Canon PowerShot SD890IS Review Wahoo! I just received my new Canon PowerShot SD890IS . Here's my review of the new SD890IS. Updated! (20-April-2008)! I like taking good photos. And I hate lugging around big cameras and equipment. And so I concluded that I needed to buy myself an awesome point-n-shoot camera. I often take pictures in difficult conditions, such as a museum where a flash camera is prohibited. Or a concert, where I can't use a flash, the lighting is low, and the people on stage are in motion. Or with the zoom cranked up and focused on a distant subject. Taking good photos in these conditions, with a small lens camera and without a tripod is a challenge at best. In comes the SD890. I was particularly excited about the SD890 because it is pocketable, yet it has awesome specifications: Image stabilization ; a 5x zoom lens, and 10 megapixel resolution. When I bought the camera, I imagined that these features would help me take much better pictures in the...

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...

Fixing a SodaStream Jet, Repair #2 - Broken Fill Button

My Soda Stream Jet's fill button broke, which means I can not longer carbonate water by pressing the pushbutton. This caused all sorts of grief in my household. Here is how I managed to repair my Jet to give it another 10 years of life (hopefully). First, a look at the button The fill button on the top of the SodaStream is actually a simple lever. Pressing down on the button moves a pin that does the actual work of pressing open the Carbonator's valve. Unfortunately, the axis point is fairly thin and can see a lot of stress. That's where my Soda Stream button cracked. [ I think the usage tip here is "don't over-press the button like a gorilla, it doesn't do anything but put high stress on the button."] Cracked levering point of the button The Pesky Lever Retaining Pin The Fix It was pretty easy for me to replace the button: Take off the back of the Soda Stream and remove the carbonator. Push out the the button lever's steel retaining pin. This takes qu...

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 ...

Using a Directional WiFi Access Point - the TP-Link CP210

I have two buildings on my property, and I wanted to bring Internet to my garage without pulling a wire. Previously I was using the barely-adequate reach of my house's WiFi, but it was just a little too far and it would drop frequently enough to be painful. My solution is a WiFi Directional access point - the TP-Link CP210. I chose the CP-210 because it was inexpensive. It only supports the 2.4 GHz band, but my goal was quality over performance. In all, it does this job perfectly. I mounted the CP-210 in my attic because it was easier to install that way. If I really wanted to I could mount it on the outside, but that means drilling holes and climbing a ladder and other things that I don't want to do. After all, it works great from inside - an outside mount isn't going to give me anything more except more work. I simply pointed the CP-210's antenna to my garage and that was it. Easy and effective. The CP-210 has a bunch of useful configuration options - it isn't jus...
