When is the best time to do laundry?

I think about energy efficiency a lot, so my question of the moment is... when is the best time to do laundry? For me, my laundry consists of machine wash and machine dry.

Washer Efficiency
With the wash, the question is when is the best time to use a pretty much fixed amount of water and energy. I think that's when electricity production is at its most efficient, which is at night and on weekends. That's because the energy companies use their most efficient electricity generators 24 hours a day, but add less efficient generators as load increases.

Dryer Efficiency
With the dryer, the question is when is it easiest for the dryer to remove moisture. I think that's during low-humidity times. Dryers draw in air to work their magic, so the more dry the air is, the more quickly the laundry will dry.

Also, note again that dryers suck in air, and exhaust warm moist air outside. During extremely cold or hot weather, a heating system or air conditioning system will need to heat or cool this new outside air. It's good to minimize this expense too. Therefore, it is best to avoid doing laundry during very hot or very cold weather.

Conclusion
So I try to do laundry on dry nights and weekends. If it is particularly hot, cold, or damp outside, I'll put off laundry for another day.

Repairing an HP Pavillion DV6 Motherboard

Here's my procedure on how to remove and replace the logic board of an HP Pavilion DV6. My model is a DV6-3122US, and many DV6s of the 3000 series are similar. These machines often fail to start due to a motherboard failure. With a motherboard failure, upon pressing power the fan will first spin and the power light comes on. The capslock key will flash white once every 4 seconds, and the f12 key will stay a solid orange, and the screen - although powered up - displays black only. Although the caps lock "single blink" indicator at boot implies a CPU failure, in my experience it is not due to the CPU itself but the supporting components on the motherboard. The only solid solution is to repair or replace the motherboard. Replacement boards are readily available. I bought one and replaced it myself. Disassembly Procedure NOTE: The screws are different sizes, and its important to reinstall them correctly. I color-coded the different screws in the photos...

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...

Various ways of powering the MikroTik hAP

I have several MikroTik RB952Ui hAP AC Lite routers. They're located in closets, basements, attics, and on desktops. Each location results in different needs in terms of power. Happily, the hAP AC Lite is quite flexible when it comes to power. Here I document the three different ways I have powered my MikroTik AC Lite routers. Power Solutions: Active PoE+ Splitter, Passive PoE Injector, and Standard wall adapter Standard Power: MikroTik (or aftermarket) Wall Wart The default way to power the AC Lite is by using its standard "barrel-style" power port, which is far more flexible than your typical router. The AC Lite accepts power between 10 and 24VDC. When using the MikroTik in a desktop configuration, I use the stock 24 volt MikroTik power adapter . The stock adapter output specifications are as follows: 24 VDC 1200 mA 2.1mm barrel Center Positive Passive Power-over-Ethernet solution: TP-Link Power Injector Sometimes it is useful to ...

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...

My iPhone is being remotely controlled by a hacker! (and how to fix it)

Who is remotely controlling my iPhone??? This is a personal story that scared the hell out of me. On Monday I was awoken by my iPhone alarm telling me that it was time to get up to go to work. I picked up the phone and looked at the day's calendar. Ug. I put it back down in its dock for a couple more Z's. Seconds later, I heard it clicking. I looked at my phone, and it looked like someone was typing on it! Click. Then a swipe. And then more clicks. One of my business apps was being operated, but NO ONE was touching my iPhone! I was sure that a Hacker was remotely operating my iPhone, digging around for my private data! This was shocking. My phone stores a lot of good stuff - my email, photos, finances, passwords and all sorts of other goodies. If someone compromised my phone they could know where I am. They could operate the cameras, the microphones - in short, they could know almost everyth...
