In this post I’ll show how to create a Node-Red subflow to control a TP-Link switch (power on/power off), using the TP-Link Cloud API.
I have an Amica NodeMCU clone and I was thinking about trying the ESPurna (means “spark” in Catalan) firmware on it.
I love to draw diagrams and create visual representations of what I do. I think it’s a great way to understand what you plan to do when designing a complex system, to document it for later, and show what you’ve done. Not only targetting others, but first of all for yourself.
This month, Dropbox has dropped support for non-ext4 filesystems on Linux. On my Linux computer, my Dropbox folder was on a ZFS filesystem… If you want to keep Dropbox syncing, they force you to move back to Ext4… non-sense, but I didn’t find any other alternative. So what I did is create a ZVOL (volume), format it as Ext4 and move my Dropbox content to it.
Here I want to define a custom Google Assistant action, which will recognize a phrase with an argument, for example
ok google, make me [a pizza], and send both the action (
make) and the argument (
a pizza) as a JSON object to an MQTT topic.
I was looking for a way to pass parameters to Yosys (that would end up in the Verilog source code) at synthesis time.
In this article, I’ll show how I connected a DIP switch to input an 8-bit value to the Icezum Alhambra FPGA board (Ice40HX1k)
This is the first post of a series I am writing about designing and running Cellular Automatons in an FPGA. I’ll end up with several variants, from one lighting up LEDs to another one drawing on a VGA monitor. But first, what is a Cellular Automaton?
