Craig's List

eBay is nice because it has a huge audience. But eBay costs the seller for the posting, commission, and the credit card (PayPal) fees. Craig's List has a much smaller audience, but it is totally free to both the poster and the buyer.

I listed my CD Changer (thank's iPod!) and some old cell phones on Craig's this weekend. And then I waited for replies. And do you know what? I got a LOT of replies - about 10 in one day.

To further ease the burden and cost, Craig's List is a "local thing" - no shipping required. The only trouble is connecting and exchanging the goods. And in the best case, the transactions are in cash.

The CD Player sold (yay!), and my cell phones grab tons of interest. [Note that all of my net reciepts from eBay and Craig's are slated to go to charity.]

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 ...

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 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...

Using a Garmin eTrex with a Macintosh or Linux

The Garmin eTrex series consists of decent, full featured handheld GPS units. The cheaper monochrome eTrex models have a basic RS-232 serial interface, and the color eTrex models sport USB connectivity. In this article I'll talk about my experience with connecting both USB and serial port versions of the eTrex series to my Mac and to my Linux-based PC. I personally use the Garmin Vista HCx GPS now, but the other Garmins in the eTrex series, including the inexpensive but well specified Garmin eTrex Venture should work the same way. Dealing with the eTrex Series with USB Most of the eTrex units with a color screen have a USB port on the back. Happily, this USB port uses a common USB connector, so it is easy to physically connect a USB eTrex to a Mac or a PC running Linux. The USB Port on an eTrex I have found two pieces of software perfect for use with a USB eTrex, without the need for special drivers: GPSBabel+ and Google Earth . The Mac version of the freeware program ...

Adding a Water Flood Sensor to my Vista-20p alarm system

My Honeywell Vista 20p alarm system is fairly comprehensive, but I want one more feature: an alarm that lets me know when my sump pump isn't working properly. Here is how I added one for about $8 in special parts. I'm afraid of a flood in my finished basement. I'm fortunate - my basement sump pump system is already redundant, with two independent pumps and two outflow pipes. The primary pump kicks in when the water level reaches 6 inches, and if that doesn't work, then the backup pump kicks in when the water level reaches 7 inches. The backup pump should never kick in unless the primary pump is having a problem pumping. But there is a problem with this setup: I might never know if my primary pump has failed, leaving me with no redundancy. I want to be informed when I have one (or god forbid, two) pump failures. My goal is to have my Vista 20p alert me when the sump's water level is ever beyond the point where my primary pump should have kicked in, alertin...

Hot (and Cold) Attic Tempertures and Electronic Equipment

An unfinished attic can be an extreme environment for electronic equipment, with conditions that are very unlike what is experienced inside normal living spaces. What's the deal with installing electronic equipment in an unfinished and uninsulated attic? I wanted to install a standard WiFi router in my attic to function as a Wireless ISP (WISP) gateway. My attic is a fantastic location from a radio signal perspective, but it is an uncomfortable place for both people and electronic gear. Although the attic is well insulated, that insulation is on the floor, designed to keep the living space of my home at moderate temperatures. As a WISP gateway, my WiFi router is best mounted above the insulation and close to the roof, where the only protection from weather extremes is the wood of the roof and a layer of asphalt shingles. Equipment Specifications and Extremes Almost all electronic equipment has a set of specifications regarding operating environment. These specifications state the...
