Made a cap for a mushroom button, with editable text.

Also made some chair thingies. We have wooden floors and her new chair has pointy feet.
Made using Openscad

I’ve got a little SDR stick a while ago with some antenna’s.
I’ve got some extra antenna’s
So I was playing around with P2000 and Airplane Radio (tracking overhead planes)
For debugging I used SigDigger

I bought a cheap esp32 display (4 inch 480×480) from China.
It also has three relays to control lights.
Below is a gallery with default screens.
Flashing OpenHasp was a breeze.
Configure the thing for HA was not so easy.
Install OpenHasp via Hacs on HA.
There is a webinterface on the display, here you have to configure wifi, mqtt and the pages.

We’ve gone too far.
IA is generating news articles and complete YT video’s.
Also, forums and news articles are made using AI.
Reviews are being generated by vote farms.
Unchecked and being re-ingested by other IA scrapers.
It’s being fed again into other new AI generators.
Content generators are not interested in if the generated content is true.
Just generate traffic and income.
I hate watching a long YT video, voice being generated, story content from ChatGPT and not fact checked.
No new information, just generic information stretched into more time you have to watch.
If there is a disaster, people generate false footage to generate traffic.
I’ll resume this rant in time .. i’m not done
I’ve got a flipper zero at last.
https://flipperzero.one/
I know, it’s more an useful toy than a serious tool.
It’s too limited. But useful for me.
Learning about tools and sub gigahertz monitoring.
I hoped to get a BFFB for it, that will be a big plus.
https://www.justcallmekokollc.com/product/flipper-zero-bffb/31
One of the first things was reflashing the device with Momentum firmware.
I’ve ordered a Wi-Fi Dev Board, so I can use Marauder.
Here are some qFlipper screenshots.
Will add pictures and info about the Wifi dev board.
Some information:
The Flipper Zero is a versatile multi-tool for geeks, hackers, and hardware enthusiasts. It is designed as a portable, open-source device with numerous capabilities for interacting with digital systems and hardware. Here’s an overview of what the Flipper Zero can do:
The Flipper Zero is a powerful tool, but its legality depends on how it is used. Be sure to respect laws and ethical guidelines when exploring its capabilities.

There is not much to be found for Waveshare 4.2 Epaper.
Except for an Arduino web example.
( see https://www.waveshare.com/wiki/E-Paper_ESP32_Driver_Board )
I reversed engineered the workings, and created a python upload script to push images.
Original workings are a mess.
Per 4 bit of color, high-low switched in a byte.
Black and red separated.
Using a till p encoding over curl commands.
My implementation uses a python script called as:

A while ago, I bought a small Dehumidifier for my wine cellar.
I liked it a lot, so I bought another for our bedroom.
I saw some posts about people asking which Dehumidifier is supported by Home Assistant.
This one is. The “Eeese Otto Dehumidifier”
This works with the LocalTuya integration.
There are many examples how to integrate LocalTuya in HA which can be found easily using a search on the net. So, I’m not going to explain that.
I could not find a configuration example, that’s why I’ll post that part here.
Pre config:

Yesterday I got my Home Assistant Voice!
This is a Non-Cloud solution like Alexa and Google devices.
I only could play with it for a few minutes because I was working on Arduino code with an ILI9341 Display and a BME280 (Temperature/Humidity/Air pressure).
Today I got some new goodies in, one of these is a LilyGO LoRa display which works on 433 Mhz.
I flashed OpenMQTTGateway on this device.
In the past, I posted about the RFCOM Gateway using Domoticz.
This runs on a Raspberry Pi.
While looking for alternatives, I found a rtl-sdr solution.
https://github.com/merbanan/rtl_433
Using this:
But I liked the ESP32 solution more.
Now I can dismantle Domoticz, which served me well for many years.
Note: This is a receiver device only!
But I only use read-only sensors like : Door/window, doorbell, temperature/humidity and Firesensors.
These are automatically detected in Home Assistant.
No more RFXCOM with a Raspberry.
I Still got 19 posts in draft, I know, but I saw a post on Reddit about tunes being played.
(Only pipe tunes) Only the lists I could find, so incomplete. (No tunes in this list from 2022-now)
Some I’ve played for 30+ years, others only a while.
I’m going to rate these soon
1st pipeband – started here at 14 yrs
2nd pipeband – continental grade 2 band
3rd pipeband – 4th grade, teaching
4th pipeband – 4th grade, teaching and piper for the Highland Dancers
A lot of tunes are being played in all bands
Own compositions are on another page
While working on a client project, I tested multiple displays.
I thought it was fun to connect the Epaper to ESPHome.
It was not without problems. For example, the ESPHome editor gave squiggly lines under type.
This has to be changed in the libraries.
