A tip of my hat for the new Roomba

I really hate vacuuming, and so I vacuum as little as possible. However, in contrast to my hate of vacuuming, I love a clean house. And so I either find myself vacuuming (yuk), or living in a not-so-clean house (yuk). So to reduce my emotional distress related to vacuuming, I recently bought a Roomba. 

Here are my impressions and some tips:  

Efficacy of the Roomba 

The Roomba certainly keeps my floors clean. I'll still have to get out the traditional vacuum to clean the moldings, window sills, and some tricky spots (like behind my desk), but the bulk of my vacuuming effort has gone away. The Roomba is not nearly as fast as the local cleaning service - but it does do a good job of covering all accessible floor surfaces. My routine: I get up in the morning, and just before I leave for work, I ask the Roomba to vacuum a particular room in my house. By the time I get home, the room's floor has been cleaned and Roomba has recharged itself. The Roomba can miss some pockets of dirt. But since I have the Roomba working just about every day, it eventually gets just about everything.  

You and your dirty, dirty dustbin 

If you have a dirty floor, the Roomba's dustbin can fill up quite rapidly. I recommend that you empty the dustbin after each run until you understand how quickly it fills.  

Roomba Power Consumption and Considerations 

My Roomba has the very neat-and-cool "Home Base" dock. When the Roomba is tired (low on battery power), it searches for the dock and plugs itself in. I hooked my watt meter up to the Home Base. When the Roomba is charging (amber light pulsing), Roomba-in-dock consumes about 30 watts. Once the Roomba is fully charged (green light), Roomba-in-dock consumes about 5 watts. When the Roomba is out of the dock, and presumably vacuuming, the home base consumes about 3 watts. My Roomba came with a metal nickel hydride battery - a battery type that is much more environmentally sound than the nickel cadmium batteries used in many other consumer electronics. It should still be properly recycled after it's exhausted (many years from now, I hope), but at least it has less toxic chemicals inside.  

Roomba the Martyr 

One of my sofas has just enough clearance for the Roomba to scoot under, which is nice because Roomba can vacuum under it. But, sadly, this sofa is quite old and not so plumb... and so Roomba can get wedged under it. Further compounding the situation, the sofa has very sharp staples sticking out of the bottom, resulting in a scarred up Roomba. Roomba senses objects (like tables and walls) by bouncing into them. And so my Roomba quickly developed "bump marks" on it's front bumper - mostly white paint from my mouldings. I haven't noticed any Roomba-generated damage, but Roomba itself is quickly looking marred up. Roomba has sacrificed its beauty for me. In return, I feed it dirt and electricity, and shovel out its dust bin.

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 ...

Porsche Key Remote Battery Repair Video How-To

We now live in the age where part of your life is spending time and money maintaining and repairing things like your car keys . My Porsche's remote key was getting weaker and weaker, until one day it stopped operating altogether. Keyless remote without the remoteness. Not so good. I was a bit fearful spending a sizable chunk of my time and money at the dealership to have such a small problem addressed, and so I decided that I would try to replace the battery myself. Items required A clear work surface A small flat blade screw driver. A quality lithium CR-2032 Battery, available here. Procedure The following video shows how I successfully opened up the key without breaking it, and replaced the alarm remote battery. In short, from the vantage point of the key's steel part facing away and the buttons facing up: I take a small screwdriver and press on the little plastic tab on the left side.  At the same time I use my fingers to start to pull the two halves apart.  From th...

Macintosh: Upgrading an eMac

It's been a long time since I wrote this article, but the fact remains: The good old eMac can still be useful if you take the simple steps to keep it as good as it can be.  All can run Tiger, and most can run Leopard - great operating systems for their day with a bit of useful life.  This article describes the procedure I used to upgrade my old eMac, including: Replacing the internal hard disk with a large capacity drive. Increasing the memory for performance Upgrading the operating system Here I'm upgrading a 700 MHz eMac, but the procedure and tasks for upgrading other eMac models should be almost identical. Upgrading versus Replacing My sister's eMac is of the 700 mhz variety, with 256 MB of memory. The machine seemed to be getting "slower", and the original 40 GB disk was becoming jammed packed with photos and iTunes, and within a few months she'd be out of disk space. There were two options to address the problems: upgrade the eMac, or go o...

Robust Installation of an HDHomeRun Networked TV Tuner. 64 OTA channels!

I added an HDHomerun (HDHR) over-the-air (OTA) streaming box to my home network, bringing over-the-air broadcast TV to my computers, phones and tablets.  The HDHR is a big upgrade from my previous setup: using a simple "window mount" antenna directly connected to my TV. A TV-attached antenna is good for watching some TV for free, but the HDHR offers so much more flexibility. Figure 0: HDHomeRun on my basement wall   My original OTA TV setup was haphazard at best. It was finicky, ugly, and hard for other people at home to use. I would actually tape my antenna to a window whenever I wanted to watch OTA TV. Plus, it only worked on my TV and not with my other devices. I wanted a cleaner and more modern OTA setup. After looking at possibilities, I developed two goals: (1) bring my OTA TV into the modern Internet-connected era, and (2) set it up in a reliable and pretty way so that other family members wouldn't have to fool around with the antenna or anything else.  With that,...

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...

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...
