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. When well executed, such designs really blur the line between being a practical device and an artistic piece. In fact his latest design, an …read more

The idea of the so-called “smart bulb” sounds good; who wouldn’t want to be able to verify the porch light is on if you’re out of town for the night, or check to see if you left the bathroom lights on in your rush out the door in the morning? …read more
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

We’ll be perfectly honest: sitting inside a heated box sounds just a bit too much like torture for our tastes. But if we did somehow find ourselves in possession of a fancy new sauna, we’d more than likely follow in the footsteps of [Al Betschart] and make the thing controllable …read more

Is “IAM” access the only method to gain access AWS?
I’m asking because I’m using AWS IoT. With AWS IoT we create things such as devices on AWS IoT Core.
However, with IAM access, after creating a “thing”, I am able to commu… Continue reading Communicating with things on AWS IoT without certificates problem
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
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

I am embedding an ActiveMQ broker with mqtt connector only. I want to use TLS. How can I do that? I prefer would to implement this programaticaly or using application.properties/yml as I am using spring.

I am working on an Angular application which evolves around MQTT for communication. The idea is that the web app is kind of a live dashboard of all clients connected and sending data, the clients will be Android Apps primaril… Continue reading Angular MQTT Security
I want to see demangled MQTT frames sent over TLS on arbitrary port.
Right now I can either of two using Wireshark.
see unencrypted MQTT traffic
see TLS packets ( with MQTT data inside)
But I cant find a way to combine b… Continue reading How to analyze MQTT packets over TLS preferably in Wireshark [on hold]
