Fresh hacks every day
A while back, [Blaise] tried his hand at getting the WebSocket protocol working with PIC microcontrollers, WiFi adapters, and a few pots, knobs, and switches. It was an excellent project for its time, but now [Blaise] has a Raspberry Pi, and the associated GPIO pins and Ethernet connection. He decided it was time to upgrade his build to the Pi, this time with a project he calls PiIO. The basic … [Read more...]
Using animated GIF images as a crude WebSocket is an idea we've never come across before, but it actually makes a lot of sense. Not in terms of it's overall usefulness, but just for the fact that the animated files work in a similar way. The nature of these animated containers is what makes it work. A GIF doesn't tell the browser how many frames to expect, so the connection is kept open until the … [Read more...]
[Blaise Jarrett] has been grinding away to get the WebSocket protocol to play nicely with PIC microcontrollers. Here he's using the PIC 18F4620 along with a Roving Networks RN-XV WiFi module to get the device on the network. He had started with a smaller processor but ran into some RAM restrictions so keep that in mind when choosing your hardware. This project was spawned after seeing the mBed … [Read more...]
This project shows you one possible way to use HTML5 to fully integrate sensor data from a microcontroller into our technological lives. Now, when we saw this tip come through our inbox we thought it would be an interesting example to learn from but we weren't ready for how truly cool the setup is. Take a look at the video after the break and you'll see that scanning the QR code on the project box … [Read more...]
