New washer confuses clock

My wife's got an LED alarm clock / radio / cassette player combination by her side of the bed. We replaced our washer and dryer with front loaders. Whenever we run the washer, the clock gains time. I figure that the variable-frequency or DC drive in the new washer must be putting out spikes onto the line, which the clock is counting in addition to the real zero crossings of the power line. I've tried looping the line cord through a ferrite bead salvaged from an old computer cord, but it didn't fix the issue. I haven't tried an external line filter yet. The vulnerability is in the clock, but it took 30 years to become evident.

I strongly agree the "throw-it-away' mentality in the USA is a disgusting Waste Management thrill. Kids in school should not have to learn student council politics. They should learn how to re-use, re-task and recycle. The 'modern family' and reality shows are promoting the idea that the correct response to the failed alarm clock would be to add the functionality of time flies -into the backyard. It is amazing that the production engineering for that clock didn't realize that kapton or some kind of shield for the ribbon cable was required. Maybe it was simply a disposable clock. I try and resist the notion that designers and production simply build for cheap and no thought. But sometimes it appears they are building things that have a programmed death rate. Nothing lasts forever but its a sad economy that builds things on one side of the planet only to have them shipped to the other side, fail and be buried here shortly after arrival. Yes kia, hyundai and the like I'm talking at you. Those things ought to come with a reclamation fee.

Habib, Thanks for the idea. I had not thought about using an old CRT monitor as an audio scope. What a great inspiration. And why would anybody with the knowledge of how to do that be in a position to be in any danger form the high voltage? Some people just live chained to all of their dumb fears.

Oh, and I took my neighbors space heater. In my defense, he's a good friend and he told me it still worked it was just loud. A little DN TLC later and it was quiet as a mouse, been using it for years. But that's it! I swear.

Ann, I just adopted a new little kitten that walked up to my door. She's tiny tiny and was sickly, I had to do something. So I guess I am guilty of taking things off of the street as well! hehe

The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
