Such is the case when I read about the ZX Gesture Sensor from Sparkfun and XYZ Interactive. Put it together with the Internet, and I just may have gotten a little slap-happy. The Sensor The ZX
particle Particle and Google Maps Integration At Google IO 2017 just a few weeks ago, Particle announced an integration with Google Maps. This integration allowed you to get the location of a Photon without the need for a GPS. Instead location is achieved by referencing the wireless access points in the vicinity (a less scary way

tessel Tessel Barcode Scanner: Software In my previous post, I show how you can connect a barcode scanner to a USB port on the Tessel, and read the scanned values. While that is interesting, what is more interesting is in doing something with that value. In this post we will take a look at finding
tessel Tessel Barcode Scanner: Hardware In addition to the two module ports on the Tessel [https://tessel.io/], there are also two USB ports. USB, while big and bulky in many IoT projects, can provide a useful access point to hardware. One example used by Tessel is a web camera [https://github.com/tessel/tessel-av]
tessel Custom Tessel Module Not too long ago now, I presented at Windy City Things 2016 in Chicago. Among the IoT boards I showed there was the Tessel. I have written about the Tessel [https://krhoyt.ghost.io/2014/11/19/tessel-to-parse-com/] before [https://krhoyt.ghost.io/2016/09/01/tessel-on-watson-iot/], and how approachable

iot Decoupling IoT Rendering I recently received a comment from a visitor using one of my Arduino-to-WebSocket examples. They had a requirement for a specific charting library. The problem is that the library could not handle the data rates coming from the Arduino. In this post I break down why that is, and give
iot IoT Weather on Android In a previous post [http://blog.kevinhoyt.com/2015/08/20/iot-with-cloudant-follow/] I talked about moving from request-response to using the publish-subscribe pattern. This pattern allows our application parts to listen for changes in a decoupled fashion. This works great with the continuous feed feature of IBM Cloudant [http://cloudant.
