Home Assistant Alarm with ESP Siren

2024-03-11 fash 2 Comments

I used to have a “professional” alarm system, but it was too limited.

But when making a new alarm system using Home Assistant I thought I could reuse some sensors and the very loud alarm.

Setting up the Alarm within HA was as described on the HA website.
I made a group for door and motion sensors.
Then I made groups for lighting and switches.

Now I can “ARM” the house.

Motion sensors like PIR and camera sensors are being used for detection.
Lights and sound will be turned on when motion is detected.
When arming the system, the siren mode of the camera’s is also turned on.
When intrusion is detected I get a pushover notification on my phone and watch.

The siren is about 4-5 Euro’s on Ali

Started working on C64Pico with Bigred

2024-03-10 fash Leave a comment

A week ago I got the last components delivered to my doorstep.

This project was made by Silvervest and it’s f*ckin awesome.

https://github.com/silvervest/c64pico

I was afraid to start this myself, SMD is on another level for me.
But my good friend Marco said … No problem!

So I ordered components online, which was not easy.
Selecting the correct parts, sizes and options.

These things are really really small

Using tweezers to place the components was even difficult.
The slippery tiny bastard got catapulted everywhere. (Or got stuck on fingers, soldering iron and alike)
Many small components got lost into the 7th dimension. Never to be found again.

Awesome to work on this together, but Marco said that I have to try it myself.
Welllll, I got 3/4 of the ATmega328PB-A perfectly soldered, then I notished that it was crooked.
Desoldering was a mess, and I heated the PCB TOO much with the heatgun.

My messed-up PCB, and f*cked-up IC. Leave it to the professionals.

Next step for me is soldering the 75 mini buttons!

Got a Trinitron display from him, I was looking for this for a long time.

Today some lasercutting for Home Assistant Spotify RFID

2024-03-08 fash Leave a comment

see:

Revisiting the Spotify Cube

Lasercutting a case and the playlist selectors.

Close-up RFID stickers I’m using.

Below is a test with different methods.
I like reading the booklets, so a CD i cool, and I don’t need a CD player.
(The RFID tag is in the case)
The little cards are for bought audio files I don’t have a physical CD for.

Wooden case with RFID reader being powered by external powerbank

What am I gonna do?
Cube as I had? Wooden playlist selectors as in above movies?
The cards I’ve printed?
Maybe a small record player with an RFID reader inside?

3D printed like this? https://makerworld.com/en/models/66671

I used MCE to control some Windows VMs and programs running in it in the past. (Below link and a web interface engine which on the backend converted BWW/BMW (bagpipe music files) to PDF automated comes to mind)

Web controller for Acdsee

Now, I implemented this:

https://iotlink.gitlab.io/

Controlling a Windows VM using MQTT, very nice!
(Use HA mqtt or mosquitto_pub in bash)

Question: anyone got a better solution to control programs within a VM? Let me know.

I’m creating a new case for my Wemos, LCD16x2, button, Led, Buzzer project (see other post)

I’m redesigning my previous case in blender.

But I really miss something like a generator function for different cases, like the one I made using Openscad.
Question: Anyone know a tool/add-on to generate cases?
I used a model of a wemos to get the usb connector/screw holes in place.

My spotify rfid case I will create using wooden lasercut cutouts.

Next one:

In the past, I’ve controlled some blender lights using python and MQTT. But now I’m trying to control it using DMX.

Example of lighting in our living using mock-up couch and tables.

I found a cool add-on called Blender-DMX.
(B.t.w. wled can also use DMX)

Looks cool but, can I make a floorplan with this?

In Home Assistant I used a HACS add-on called : Art-net LED Lighting for DMX

Configuration can be done in configuration.yaml

light:
- platform: artnet_led
  host: BLENDERHOSTIP                   # IP of Art-Net Node
  max_fps: 25                           
  refresh_every: 0                      # Resend values if no fades are running every x seconds, 0 disables automatic refresh
  node_type: artnet-direct              # Which protocol to use
  universes:                            # Support for multiple universes
    1:                                  # .Nr of Universe (see configuration of your Art-Net Node)
      send_partial_universe: True       # Only send the universe which contains data
      devices:
        - channel: 1                    # first channel of dmx dimmer
          name: dmx_dimmer_rgbw         # name
          type: rgbw                    # type
          transition: 1                 # default duration of fades in sec. 
          channel_size: 8bit            # width of the channel sent to DMX device, default "8bit", "16bit", "24bit" and "32bit" 
          channel_setup: Wrgb           # This is the magic to get colors correct

It works, but I’m not happy, anyone got a better solution?

And I have to check out GDTF profiles for fixtures.

At a later stage I’m going to 3d print a white floorplan about 1cm high, with LEDs and buttons. A floorplan you can hang on your wall.

Adding a VGA terminal to my 6502

2024-03-05 fash Leave a comment

Using a LilyGo TTGO ESP32 VGA32, I’m connecting my breadboard 6502 to a serial vga terminal with its own keyboard.

Due to a lot of moving around, new places, new homes I dumped a lot of terminal hardware.
Also are those old terminals too big and use too much power.

I’m going to use this DIY screen.
https://www.henriaanstoot.nl/2021/03/24/broken-or-slow-laptop-screen-still-works/

Using the Libraries from Fabrizio Di Vittorio, named FabGL, you can transform this device into a dumb terminal, game device, VIC-20, a 8086 pc and more.
There are even some projects to turn this into a C64.

Some generic testing using sound and DOS

But the main thing I want to do: A simple terminal.
(I probably revisit the other options again at a later stage)

Soldered some pinheaders on the device for serial

My Wozmon bios has bare minimum support for serial communication, so i have to do some bitbanging.
(6502 is using a 6551 ACIA)

Sound from the ESP32 VGA board.

Chipset: TTGO Micro32 (ESP32 240Mhz dual core processor)
Flash memory: 4MB
SRAM: 520KB
Built-in Bluetooth
Built-in Wi-Fi
Supply voltage: 3.3V DC or 5V DC
GPIO voltage: 3.3V*
USB to serial converter: CP2102 or CH9102F (drivers)
VGA connection
PS/2: keyboard connection
PS/2: mouse connection
Built-in Li-ion/Li-Po battery charging circuit: TP4054 chip can charge up to 500mA

Home Assistant and Harmony Hub Scripts

2024-02-29 fash Leave a comment

I’ve got a Logitech Harmony Hub to IR control devices.

When adding this to your home assistant, you initially only get the Activities.

But I want to add single button presses.
I was going to re-visit my IR remote project.
(The IR blaster and the IR wemos, see previous posts)

Thanks to Duncan I had a second look at this solution

Check the files using the file editor.
Search for /homeassistant/harmony_xxxxxxxx.conf

It will show the Hub devices and their capabilities.

Short example below

                "PowerOff",
                "PowerOn",
                "PowerToggle",
                ".",

            "id": "67134775"
        }
    }
}

Lets create a Script for this

See the IDs above to refer to commands below.

    target:
      device_id: 7e82a825decabedbc98a0b5ce2ac5d78

Step one, change your main DNS resolver to that one from your provider or 1.1.1.1 (cloudflare)

Goto https://www.hawking.org.uk/ in your browser

Check youtube, facebook and more.

Set you DNS to 8.8.8.8 (google)

Do the same (even in a incognito browser).

I haven’t seen a Hawking recommendation on YT for ages, I just checked a website with information on another machine.

Kodi camera stream push playlist

2024-02-29 fash Leave a comment

Below is a solution when you want to stream IP camera’s in Kodi/Libreelec .

You can push these commands using Nodered, Bash script or whatever.

First make some camera scripts in your profile directory.

Examples:

# Kodi on Linux/Raspberry
# Place a file cam1.m3u in .kodi/userdata/profiles/(kodiprofile)/playlists/video/
rtsp://admin:secretpass@192.168.1.123:88/videoMain

#and another one in cam2.m3u (another example mjpeg example)
http://192.168.1.124:8000/stream.mjpg

#For windows it is in
C:\Users\(Username)\AppData\Roaming\Kodi\userdata\profiles\(kodiprofile)\playlists\video

Enable http access in Kodi and run the playlist using curl

curl -i -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"Player.Open","params":{"options":{"shuffled":false,"repeat":"off"},"item":{"file":"special://profile/playlists/video/cam2.m3u"}},"id":"1"}' http://KODISERVERIP:8080/jsonrpc

A bash loop script

while true; do
curl -i -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"Player.Open","params":{"options":{"shuffled":false,"repeat":"off"},"item":{"file":"special://profile/playlists/video/cam1.m3u"}},"id":"1"}' http://KODISERVERIP:8080/jsonrpc
sleep 10
curl -i -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"Player.Open","params":{"options":{"shuffled":false,"repeat":"off"},"item":{"file":"special://profile/playlists/video/cam2.m3u"}},"id":"1"}' http://KODISERVERIP:8080/jsonrpc
sleep 5
done

Three channel mixer for ay-3-8910 is almost done.

2024-02-28 fash Leave a comment

At the back the 8 pin single channel lm368 amplifier.
At the front the 3 channel setup.
I still have to tweak the resistors, and potmeters.
Then I can make a permanent PCB, and figure out the connections to the 6502.

At the moment, the Arduino Nano is playing some real sound samples by using the registers of the sound chip.
The music is being played by sending the register dumps directly to the chip.

Much like i’ve been using SID register dumps to play songs in another project.

This is version 0.1 .. do not use.
If its wrong, or can do better please mail me.
Oh it needs a 1k resistor from the 20K’s to ground I think.

What to do when waiting for your ribs on the smoker. (Programming some python)

2024-02-25 fash Leave a comment

This time I used a rub with the following ingredients:
Seasalt, garlic, brown sugar, mustard seeds, paprica, cilantroseeds, black pepper, red pepper, oregano, thyme and cumin.

Doing a simple 3-2-1 smoke session, so .. what to do in dose 6 hours?

Lets make something using a Sense hat and Python.
Same HAT I used for my xmas ornament thingy in our tree.

Generate a large maze (80×80 for now)
Paint the maze using colors on the SenseHat
Read joystick movement and scroll the maze accordingly, keeping the player in the middle

Now I have to paint my ribs with BBQ sauce, and leave it in the smoker for yet another hour. (Nice glazing)

Next steps for the maze:

Use a better way to generate (reverse backtracking as I made for my other maze thing)

(Blind) Maze puzzle now with generation and play modes.

Wall collision detection is nearly completed.

Better placement “birth” of player in the maze.
