Interested in a bit of home automation? Don’t know where to start? We just found a great Instructable on making your own bluetooth controlled relay module!
[Kyle's] been working on this for a while, and finally at his 5th iteration he’s ready to share it with the public. It’s a project you can make from scratch, and each unit will cost approximately ~$25 in components — which can control up to two outputs.
He’s included an inkscape PCB layout which you can easily etch on your own using the toner transfer method. The heart of the build is an Atmega328, which helps keep the costs down — after all, it is only controlling two outputs! Then it’s just a matter of adding the components, a bit of soldering, and uploading the firmware!
The entire design is open source, and [Kyle] would love some feedback to continue improving upon it. The write-up is quite thorough, so if you’re interested, take a look and leave him a comment!
