Freeform ESP8266 Network Attached Data Display

Like many of us, [Josef Adamčík] finds himself fascinated with so-called “freeform” electronic designs, where the three dimensional circuit makes up sections of the device’s structure.

Transcending the Stack with the Right Network Protocol

The increase in network-connected devices the past years has been something of a dual-edged sword. While on one hand it’s really nice to have an easy and straight-forward method to have devices talk with each other, this also comes with a whole host of complications, mostly related to reliability and …read more

Arduino Enters the Cloud

Love it or hate it, for many people embedded systems means Arduino. Now Arduino is leveraging its more powerful MKR boards and introducing a cloud service, the Arduino IoT Cloud. The goal is to make it simple for Arduino programs to record data and control actions from the cloud.

The program is in beta and features a variety of both human and machine interaction styles. At the simple end, you can assemble a dashboard of controls and have the IoT Cloud generate your code and download it to your Arduino itself with no user programming required. More advanced users can …read more

Controlling Non-Googley Devices With Google Assistant

In the near future of the Smart Home, you will be able to control anything with your voice. Assuming that everything supports the Smart Home standard you chose, that is. If you have a device that supports one of the other standards, you’ll end up uselessly yelling at it. Unless you use gBridge. As the name suggests, gBridge is a bridge between Google Assistant devices and the rest of the smart home universe. It’s an open source project that is available as a Docker image can be run on a low power device in the home, or on a hosted …read more

The modern social-networking fueled Internet loves two things more than anything: pets, and watching other people do stuff. There’s probably a scroll tucked behind a filing cabinet at Vint Cerf’s house that foretells anyone who can harness these two elements will gain control of the Internet Ready Player One style. If so, we’re thinking [Tyler Pearce] is well on his way to ascending the throne.

In an effort to make the Overwatch Twitch streams of his betrothed even more enticing, [Tyler] came up with a way for viewers to feed their dog Larry by dropping a command in the chat. …read more
