Make one Proxmox node to wake-on-lan another

· 3 min read

Nothing is eternal, especially the relevance of documentation. I think help.ubuntu.com is an absolute winner, holding the largest number of outdated and irrelevant pages. But that's not a topic for today's post. One of my Proxmox cluster nodes can't power itself on after the outage. But it supports wake-on-LAN, so I decided that another node could power it on. And the simplicity of this task was overrated by me.

Using stepper motor to control amplifier volume knob with ESP8266 and ESPHome

· 5 min read

My living room multimedia setup consists of numerous devices with varying degrees of stupidity. I’m chasing to improve it adding additional DIY hardware and functionality not always because of hate of TV remotes but also because I’m in love with IoT and soldering. First, I’ve added WiFi power control to my Cambridge Audio amplifier, then I’ve implemented WiFi-to-IR remote control to the TV. Then I decided to improve sound quality from TV and added a DAC between the TV and the amplifier. It is connected to the TV via Toslink optical cable. And it broke my volume control because you can’t change the volume on a digital output port on a TV, you forced to rotate the knob on amplifier instead.

DIY Smart Appliance: Adding WiFi power control to an integrated amplifier

· 3 min read

Previously I was using JBL Bar connected to a TV in my living room. It was controlled with WiFi IR bridge, so whenever my Chromecast or PS4 was in playing state, the Bar was turned on and ready.

Now I have passive speakers with a simple integrated amplifier, and it can’t be turned on or off without physical interaction. You need to press and release the button on the front panel to toggle amplifier power. So today we will add WiFi power control to Cambridge Audion AXA25 integrated amplifier.

Yes, it is possible and you don’t need to build anything from sources. Sending SMS from your home could be useful, for example, to send emergency alerts. But what about receiving and parsing SMS messages? Well, I used it to integrate my car security system with my Home Assistant. Now my Home Assistant could start the engine of my car automatically to warm it up before driving to work.
