Ground loop works perfectly
I have had a Bose Companion 3 Series II power speaker system for many years, and I love it. It is used exclusively as sound output for my iMac computer. The only problem I have ever had is that the Bose amplifier develops an annoying hum, when left on for a period of days, that cannot be remedied any other way than to shut it down for a period of time. I tried everything to fix the problem. Nothing worked until I found information on a simple device that eliminates the problem. The hum is caused by a complex (to explain) potential difference between two grounded devices--e.g., my iMac and the Bose Companion 3 amplifier. The ground loop isolator contains a transformer that isolates and prevent any throughput which may occur between the two grounded devices. All you need to know is that this mPow device works. When I first connected it between the iMac and Bose, it took a minute or so for the device to function. Perhaps, it needed to bleed off the difference in potential between the two electronic devices. I don't know. All I do know is that it works perfectly. The annoying hum is completely gone and it hasn't returned.

Good product: bu,t does not fit powerheads universally, and fittings can crack
2 of 4 found this helpful I bought the Filter Max 3 to serve as a pre-filter for my fluidized sand bed filter. The sponge and filter holder sceens are excellent quality. One immediate drawback is that the supplied fittings do not fit the powerheads and pumps that one might use inside the aquarium to run various hanging filters and sump pump systems. If you don't have a bunch of spare odds and ends parts and filter fittings laying around to try, then you might want to be think twice before purchasing. On the other hand, the Filter Max 3 is not so expensive as not to take a chance. More importantly, one must be careful in fitting and refitting the clear plastic fittings. The fit is tight and the plastic these fittings are made with cracks easily. I found out too late that this is the case, and I ended up cracking two elbows. Because the plastic is hard, not supple, to begin with, my guess is that as it is exposed to water inside the tank over many months, it will become even more brittle as it loses plasticizers. I would recommend that the manufacturer turn to a plastic of the kind used by Eheim in its filter pipes and fittings, or to simply black plastic found in a lot of other plumbing applications. I recommend that users of the Filter Max 3 use silicone grease or a vaseline product sparingly with connecting the fittings. That should prevent the cracking problem.

Expanding your home network
6 of 6 found this helpful Apple AirPort Express Base Station Wireless Router is a good and inexpensive way to expand your network's reach within your home, especially if you already are using an AirPort Extreme (abbrev. Extreme) primary LAN (local area network) router.
First, locate the AirPort Express (Express) physically where you think it will do the most good--e.g., the other end of the house yet within signal range of your primary router. Any wireless router should be place high up near the ceiling of the room in which it is located in order to obtain the greatest signal range.
Next, plug in the Express and return to your Mac computer, where you will find and open the AirPort Utility app. The app will almost immediately find the Express and ask whether you want to add it as a bridge router to your present network. Answer 'yes' and the connection is made. The Express will repeat synchronously the data signals received from the Extreme and transmitted by users on your LAN.
Adding an AirPort Express will not increase the speed of your network, since it is limited by the speed of data transferred through the Extreme. However, you should find that you have full signal strength available for wireless devices throughout the house now, especially in areas where before signals were weak, intermittent, or non-existent.
The price of an AirPort Express is inexpensive compared to the benefits it offers, and for Mac users, it could not be easier to set up and use. I strongly recommend this approach to extending the range and strength of your LAN.
