Geothermal heating and cooling pros and cons

I know several people using geothermal heating and cooling. My neighbor really wanted me to switch to it. But what is geothermal heating and cooling? What does it cost? it didn’t make sense to me to replace a highly efficient furnace and AC that were working properly. Now that my furnace needs a costly repair, I’m looking at geothermal heating and cooling pros and cons. Here’s what I found out.

Geothermal heating and cooling is very environmentally friendly, and under the right circumstances, saves you a large sum of money every month. It’s not for everyone, but the people who like it like it a lot.

Repair damaged PCB traces with wire

Repair damaged PCB traces with wire

I had a 286 motherboard from the late 1980s with battery damage. A leaky battery corroded two traces completely through, severing them and rendering the board inoperable. Here’s how I repaired the damaged PCB traces with wire.

Fixing broken traces is a bit of a lost art, because it’s easier to just swap the board. But when the board is rare and/or expensive, it makes sense to repair the broken traces instead. These types of repairs can be a bit intimidating, but they’re easier than replacing a chip. And then you’ve saved a scarce board from oblivion.

My Ikea furniture adventures

I asked my wife what she wanted for her birthday. She said she’d think about it. Then she asked if she went to Ikea and brought some stuff home, if I’d put it together. I said I would. So, how hard is it to put Ikea furniture together? What tools do you need to put together Ikea furniture? I learned all of that and more.

What to do with old countertops

What to do with old countertops

When you have an older home, eventually the question always comes up of what to do with the old countertops. It’s actually two questions. First, there’s the question of how best to replace them without turning your kitchen renovation into a nightmare that costs ruinous amounts of money. Second, there’s the question of what to do with the old countertops afterward. Let’s tackle both questions.

While methods do exist to resurface existing laminate countertops, it’s usually easier and cheaper to replace laminate countertops with new ones. The old countertops may have other uses around the house. And yes, I will deal mostly with laminate countertops here. Usually laminate seems to be the type people want to replace.

Make your own train backdrop

Sometimes you may not be able to find a commercial backdrop for your train layout that you like, for whatever reason. You can make your own train backdrop more easily than you may think. Adding a backdrop makes your layout look finished, and larger. Adding a thin backdrop makes my 8×8 layout look more like 10×10, or perhaps larger.

Are home warranty plans worth it?

Are home warranty plans worth it? Do you need a home warranty? As a longtime home owner and landlord, I have experience with home warranties. Here’s when I’ve found they’re worth it, and how I decide when to go without.

Offering a home warranty certainly makes your home more marketable when you’re selling. But when it comes to buying one myself, I don’t bother anymore. Here’s why.

TV wall mount won’t unfold

TV wall mount won’t unfold

I bought a TV wall mount, and then when I went to set it up, I couldn’t unfold it to attach it. It took some time but I figured out what to do. Here’s what to do when your TV wall mount won’t unfold.

TV wall mounts have to be very tight to support the mass of a TV, and without the mass of a TV on them, they can be difficult to unfold. You may have to get creative to reach the adjustment screws, and try turning them the opposite way you think. If you just can’t reach the screws, a little bit of disassembly may be necessary to get to them, but this isn’t terribly difficult to do.

How to reboot a modem and router

How do you reboot a modem and router? And does it really do any good? The occasional reboot can be good preventative maintenance, so here’s how to do it, why, and how frequently. And while rebooting is something tech support tends to use as a crutch, it’s also frequently very effective. That’s why it’s always been one of the first things I try when troubleshooting.

There are usually two or even three ways to reboot your router, and there may be more than one way to reboot your modem. Usually the simplest, safest way is just to power-cycle them.

Which post office is open on Sunday?

Which post office is open on Sunday?

If you ask the US Postal Service, the post office is closed on Sundays. But that doesn’t mean you can’t mail a package on Sunday. There’s a loophole, and I’ve used it myself. A lot. This can be a useful life hack.

While the traditional post offices are not open on Sunday, many USPS retail stores are open for limited hours on Sundays. You can mail a package from one of those stores if it’s open, and it will get a Sunday postmark.

Marx caboose values

While we’re discussing Marx values, I might as well go ahead and write about Marx caboose values too. It’s only a matter of time before someone will want that information too.

Cabooses are much like any other Marx train. The most common Marx cabooses are worth around $10. There are a couple dozen Marx cabooses worth more than that.
