Can you put peel and stick tile over ceramic tile? You certainly can, but there’s a right and a wrong way to do it. Do it without prep time, and you’ll end up with a floor that looks bad and doesn’t last as long as it could. Prep carefully though, and no one will ever know.

How to fix loose outlets

Dave Farquhar DIY February 7, 2018March 29, 2023

Loose electrical outlets are annoying. They make it hard to plug stuff in and unplug it again. They cause cover plates to break, and can even cause the outlets themselves to break. In some cases, they are even a safety issue. Here’s how to fix loose outlets.

Sometimes you get lucky and this is a five-minute fix with no supplies. Even when it isn’t, you can fix this in less than 30 minutes using less than $5 worth of supplies in most cases. Sometimes you can fix it with junk you have laying around. And it’s worth doing, as loose outlets can lead to broken cover plates or, worse yet, arcs and burns.

What are thermal curtains?

Dave Farquhar DIY, Saving money January 29, 2018February 24, 2018

What are thermal curtains? Thermal curtains are thick curtains with multiple layers of fabric and a layer of foam to help block the flow of heat. This helps you save energy, while also having sound dampening effects.

Thermal curtains work similarly to blackout curtains. But since their intended purposes are slightly different, a thermal curtain might have some shortcomings as a blackout curtain, and vice versa. If you want a curtain to do both, make sure it actually states that it does both. Otherwise, I recommend getting dark-colored thermal curtains. A blackout curtain may not block as much heat as you would like. Similarly, a light-colored thermal curtain might let in more light than you like.

Dave Farquhar DIY, model railroading January 11, 2018December 29, 2017

Is oil conductive? It’s a frequent point of debate among model railroaders. But generally speaking, oil isn’t a very good conductor. That said, oil can be a good conductivity enhancer, even though it’s not a very good conductor on its own.

Here’s how to use oil to improve conductivity in electrical applications. This can work whether you’re talking household current, or low-voltage applications like you find in model railroading.

Light switch without ground

Dave Farquhar DIY December 29, 2017September 8, 2023

Will a light switch work with no ground wire? Usually. Does a light switch need to be grounded? Not necessarily. Here’s why you normally want a ground, and what your options are for a light switch without ground.

For a normal light switch, the ground is a safety feature, not necessary for operation. You can leave that screw unconnected if you don’t have a ground wire, or if you have the wire but no screw on the switch, you can ground the switch another way.
