Female Speaker: A couple of months ago, I worked on a product called Tweet-a-Watt. It's a project where I took this Kill A Watt meter say, off the shelf $20 parameter from HomeDepot and I upgraded it to include a wireless XP modem. This is a ZigBee wireless transceiver and that project looks pretty well, but one of questions people keep asking is, well it by default, you know, you show that you need to have a computer on and the computer receives that data and sends it to Twitter, the tweeting part. But, you know, isn't that kind of silly to have a parameter that's on all the time like which be good if it was a low power system. So I am going to show how I actually do this at home because, I got this $40 ASUS wireless router and this is way wireless router we use on the apartment and I've upgraded it by adding a XP modem just like one in the kill a watt and this one has a nice big antenna, so it can receive transmissions from all over the place and these indicator LEDs show when it's on and receiving data and basically I just upgraded this router with open WRT according to mightyohm's excellent instructions and then soldered in header and it goes straight to the XP, this top serial. there is a serial port. So, it's pretty easy to get it running and then I just run python on the router and so it's acting as an access point at the same time it's also grabbing this ZigBee data passing it and then setting it over the Wi-Fi connection to my Twitter account.
Male speaker: So people are going to ask, doesn't this interfere with the other Wi-Fi signal?
Female speaker: Nope. 2.4 Gigahertz band is actually pretty wide and there is plenty of space for your ZigBee and Wi-Fi and any of those tons of stuff that stocks 2.4 gigahertz vista who works just fine. Also both of these are pretty smart protocols. They hop around a little big, you know, if they were interfering in, there is lots of retransmission. So we had no problems before, you now, we just kind of - others 2.4 gigahertz antennas on here. But, yeah I mean it's, it's perfectly find ZigBee in this Wi-Fi.
Male speaker: And if someone wants to see this live on Twitter where do they go?
Female speaker: They go to twitter.com/Tweetawatt.
Male speaker: And if they wanna get all the information for this projects?
Female speaker: This project is based of a mightyohm's instructions. So, you should go to mightyohm.com and look at this Wi-Fi radio and basically follow all the instructions and then before you get to the radio part, install python instead and then actually the code just runs as is on the router, the same code that runs on the Windows or Linux of our computer. It just base window Edex, goes straight to this robotics computer.
Male speaker: Yeah and if you don't want to build this project, you can still get this router and turn it in to a Wi-Fi radio which is really cool project that mightyohm did too. Okay well great. See you, bye.
Female speaker: Bye.
