Update on MetroPCS Service: Wifi Calling

I have another MetroPCS update, this time related to international travel.

I flew some 5000+ miles to some foreign countries with my MetroPCS-powered iPhone.

First, when I landed, I had no service: no voice, no texting, no SMS. This wasn't a surprise, as MetroPCS is a US-only provider.

But this lack of service is actually a great thing, because it prevents a huge phone bill. I recently traveled internationally with my AT&T-powered iPhone, and a few minutes of Internet usage (exclusively to do a flight check-in) cost me $40. That kind of AT&T gouging won't be happening with MetroPCS.

BUT, there is something more exciting: Wifi Calling from International Locations!

Once I was hooked up to a local Wifi access point, I could make and receive phone calls and texts using my MetroPCS phone number. So in a way, I was very connected, and had zero additional charges.

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...

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 ...

Fix a bad MacBook trackpad

The Problem: A Poorly-Behaving Trackpad Button MacBook trackpads buttons are going bad. Happily, there is a quick and technically-simple fix that may work for many MacBook owners with a misbehaving trackpad. A few months ago I started to notice that my trackpad was operating in a funky manner. The trackpad button had lost its solid click and turned mushy. As I typed the trackpad button would mistakenly register clicks, and the cursor would jump all over the place; The cursor would jump around and my words would end up jumbled. Or a button press wouldn't register at all, and I'd end up trying to smash down of the button with no response. It was the worst experience I’ve ever had with a keyboard and mouse. I tried every technique I could find on the web to try to fix my bad trackpad button – from sliding paper through the gap around button, to MacBook disassembly and vacuuming everything. Nothing made it better. My MacBook was fairly unusable, and getting worse. Af...

The Yamaha DD-65 and YDD-60 Digital Drums

Almost everyone I know who is into drums should get their hands on the Yamaha DD65 . It's a low cost, fun little kit that you can throw in your car to jam with your buddies. It's a lot easier than throwing your gear in your Subaru. The DD-65, also known as the YDD-60. Eight pads in a pretty package. I've owned the older, venerable DD-55 for about five years. The DD-55 is the ancestor of the newer DD-65, and is an evolution of the DD-50, which was first released some time in the mid 1990s. I just put my DD-55 on this light snare drum stand it's ready for some jamming. The classic DD-55. Seven pads of rockin' fun, since about 2001. Yes, everyone will tell you that the DD-55 isn't actually a real drum kit. No kidding. However, a skilled drummer can get some great sound out of this little box, and you can definitely keep the band together with it. Plus, it's perfect for apartment living.

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...
