Product Information

Grabbed the first to hand (was in a hurry) and got a perfectly rectangular smoke ring from between the case halves of the handheld 😭 If anything having Alexa glowing in the corner is just a reminder of that and it may serve to stop you from saying something you shouldn’t in range of one of the other 10 microphones you have in your house. Very true – Got one for my gran for exactly this reason. She’s in her mid-90s and partially sighted, plus the obvious mobility/dexterity issues of old age; so its a pretty ideal solution. Got to agree it seems pretty unlikely – i’ve built a few audio projects over the years, and generally found that microphonics only occur with med-high capacitance ceramic types (when tantalum caps are often a better fit).

During the 20 years I’ve used USB I’ve seen exactly one bad USB cable, and even that was dead on arrival, not worn out. Having lost zero devices to bad USB-A/Mini-B devices to bad ports, but countless cables, I see the trade-off differently. They moved the delicate bits to the part most easily damaged. If you really want a “cover your ears” feature I would suggest doing something more direct than setting some pin high. Is that just a link to a GPIO on the Dot’s CPU? Then it’s software that causes it to mute the mics when it sees it’s high. The very next firmware update could change that behavior.Even if you’re not interested in restoring its USB port, [Brian] has uncovered a wealth of fascinating hardware information about the Echo Dot during his deep-dive. He’s mapped out many of the test points located throughout the device’s PCBs, and found a few interesting points that might be worth further investigation. For example, he found that driving one of the pins high would trigger the Dot to mute its microphones; which could be useful for anyone looking to cover Alexa’s ears. If you’ve had a stroke or paralyzing accident Alexa is a MASSIVE improvement to quality of life, at a price that can’t be beat.
