Using USB-Powered Fans (AC Infinity MULTIFAN S5) to Cool Entertainment Devices (Comcast X1 DVR)

Standard

Our X1 DVR simply can’t handle any heat buildup. This is probably largely due to the fact that it lacks any fans and several comments on the Internet seem to indicate that the device is underpowered and thus works harder to handle high-quality audio and video (and as a result it generates more heat). I’m undecided on whether or not the box needs to be replaced. The features are fine and when it isn’t having issues it works very well.

Lately I’ve started to experience the same symptoms of the box overheating even though it’s still outside of the entertainment cabinet and the air conditioner is usually on. This may have something to do with using a different TV, which is directly above a small part of the DVR’s case and perhaps restricting airflow in that area.

Last weekend I attempted to use a very inexpensive USB fan to cool the box. It was very basic; little more than a USB plug and a fan motor. It did actually work but it was on a flexible arm, which generated a lot of vibration and thus a lot of noise. Even though it only cost about $5 it simply wasn’t going to work. I also suspect the fan wasn’t intended for continuous use as I noticed the motor was warm when I removed. I dropped it into a box of unused devices and decided to look for something specifically made for this purpose.

That’s when I found the AC Infinity MULTIFAN S5 on Amazon.com, which appeared to be a much better device for cooling the DVR (and indeed, it is). It features two fans that work from a single USB connection. In addition, more fans can be chained together though I don’t have a need for this capability. They truly are very quiet. The fans have a single switch that can be used to turn them off or to a low, middle and high speed. The highest speed isn’t very loud and the set is much, much quieter than the first fan that I had tried.

At $16 it looks like a good deal and even if I replace the DVR with something better, down the road, I can still reuse the fans with other devices. So far I’m extremely pleased with this purchase.

Logitech Harmony Companion All in One Remote Control

Standard

Last year, after we moved, I grew tired of having to hunt for all of the various remotes every time we wanted to watch one of the two main TVs in our home. Our toddler had a habit of tossing the remotes under the couch, beds or various nooks and crannies. Finally, I decided to consolidate by researching the current Logitech universal remote systems.

After some basic research I determined that the Logitech Harmony Companion would be a good fit for our needs. I would have preferred to get a Logitech universal remote with an embedded touch screen but those were well outside of our price range. The retail price of about $140 is still a bit pricy but the features made it appealing to me.

It’s capable of controlling up to eight entertainment devices; the TV with the most devices in our home has no more than five connected (including the soundbar). The system is composed of a hub (controller) and a Logitech remote. It also provides a remote IR blaster and a mobile app. The app is required to configure and update the system so you need to have a compatible phone to manage it. The mobile app also functions as a universal remote, which can be handy when our toddler has managed to hide the Logitech remote as well (or on very lazy days when you’re tired of getting up for the hundredth time and the remote itself is way, way over there on the kitchen counter).

Saving TVs from Angry Toddlers (Vizomax TV Screens)

Standard

Last summer I purchased the largest TV we’ve had in our house; a 55-inch LCD. In addition, it also supported 4K HDR. Over the course of a few weeks we eventually picked up a couple of 4K movies including Planet Earth 2 and I already had some games that could take advantage of the TV’s high quality. I splurged on this TV and spent $600. Granted, one could easily spend much more but for us it was a stretch.

We were able to enjoy the TV for several months, until one day in late November or early December. On this day our toddler became angry about something that was probably very insignificant in the grand scheme of things (at the time he was almost two and a half so, as with most toddlers his age, anything could upset him). I don’t recall what it was though he probably wanted to go outside to the playground. If that was the case then I wouldn’t have let him because it was dark outside or because we were preparing to eat. He didn’t mind using the word “no” but he did not like to have it said to him.

I turned around and went back to the kitchen where I was preparing some food and putting up dishes. I just happen to be looking his way when I saw him angrily pickup a Christmas decoration from our coffee table. It was a wooden, triangular Christmas tree-shaped piece. He threw it at the TV. Hard.

A Good USB Microscope for Education and Fun (Plugable USB 2.0 Digital Microscope)

Standard

IMG_2520.JPG

Even though our son isn’t yet three years old I wanted to go ahead and introduce him to some cool science. I had the idea that a USB microscope might be a fun way. We could look at various things up close, including insects. After reviewing several devices I decided the Plugable USB 2.0 Digital Microscope with Flexible Arm Observation Stand for Windows, Mac, Linux (2MP, 250x Magnification) would be a good choice. With a birthday coming up soon I chose to add it to my wishlist rather than outright buy it though at only $35 it’s a great price. Sure enough, someone bought it as a gift.

The only thing I can’t offer a comment on at this stage is how well it holds up as I’ve only had it for a week. I’m impressed by the simplicity of how it works. The device easily connected to my Mac and instead of requiring the installation of driver software it connected as a standard USB webcam. At this point the only software I’ve used to view and capture images is Apple’s built-in Photobooth app.

The microscope has a built-in LED light with a plastic guard surrounding the camera. To view something up-close one simply holds the guard against whatever is being inspected. The focus is adjusted by twisting the middle, rubber part of the camera assembly.

It’s USB only though it wouldn’t take much effort to connect an HDMI cable to my laptop and send the video to a TV. I’ve only used it on macOS though its supported on multiple operating systems.

Here are some sample images:
