Xbee sensors at Lowe’s?

Lowe’s, the home improvement big box store, is selling some home automation items which might be Xbee compatible. They’re being sold under the brand name Iris. There is some debate as to whether they’re Xbee, or just 802.15.4 hardware. Either way they might be worth checking out for your wireless projects.

LG washing machine that phones home

LG has built an interesting troubleshooting feature into some of their washing machines. This video shows the encoded audio it will output if you use the right button combination. You’re supposed to hold your phone up to the machine while talking to customer service and they’ll be able to get some type of debugging information from the dial-up modem type of sounds. If you end up decoding this audio we want to know about it! [Thanks Pedro]

  1. There is an Android app for the LG diagnostics. I am a TV and appliance repair tech and use it from time to time. Its also on some of their other products like dishwashers, fridges, and dryers.

  2. So this post reminded me that solid state hard drives tend to be mostly empty space… and it turns out this is also true for the new cheap 8GB transcend SD cards I got from Amazon yesterday:


    Quick snip with a pair of scissors and I’ve got a working short SD card that sticks out about an eighth of an inch from the board edge on the Raspberry Pi.

    Shows up no problem on my laptop… will grab an image from my working RPi card and stick it on there. I wanted to do a backup anyway.

  3. Re: LG Smart Diagnostics, I found interesting patents titled DIAGNOSTIC SYSTEM AND METHOD FOR HOME APPLIANCE. Go to patents.google.com, search for DIAGNOSTIC SYSTEM AND METHOD FOR HOME APPLIANCE, click on one of the results, then click Download PDF. The actual implementation may vary from the patent, but hopefully the information is a good starting point. I see “zero” is 2.6 KHz tone and “one” is 2.8 KHz tone. I don’t have enough motivation right now to wade through the patentese to understand the higher level data structures and learn enough audio manipulation to analyze if the sound from the video matches.
