Use a little spoon NOT a knifeGet your fingers underneath the membranePreparing the ribs, getting the membrane off.
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)
UPDATE: AccessPoint on Arduino implemented with captive portal for Wifi Configuration
Got my Waveshare Epaper Cloud running on ESPHome
This is a Epaper display with a 2000mAh Lipo and a passive buzzer. Running parts of my Smoker monitor.
Below a little movie clip with RTTTL sound notification. (Send from Home Assistant) B.t.w. RTTTL are those ringtones we used to have. (Ring Tone Text Transfer Language)
Sending from HA
Parts of the ESPHOME Yaml NOTE: For the time, you need the time integration to get hours:minutes as a sensor!
This is part of a test where my friends and me can have notifications LEDs over the internet.
Using certificate parts from: Controlling the led will be done using Mattermost webhooks, or slashcommand with custom scripting. (Mattermost is my own hosted chat server)
Not posted in the past, new version using ESPHOME and a m5stickc
Previous version using a ESP12
A “watch” with core and environment temperature of my smoker with a alarm, and button for timers.
ESP32 dac’s drawing on oscilloscope ( no additional components)
ESP32 in front of scope, two clips for x and y
For above i used sin/cos functions 2:3, which creates Lissajous figures. See: https://www.henriaanstoot.nl/1992/01/01/oscilloscope-graphics-using-a-amiga-bonus-vectrex/
3 battery operated buttons (no wires needed) to control my shelly dimmer at the dinner table.
left button on, middle steps per 20% and 3rd button off. (This cheapass button only sends ON commands)
I made my own Mqtt to speech thingy in the past. Sending a text to a mqtt topic would be picked up by my domoticz raspberry and using a bash script the topic payload was converted to speech and being played on a connected speaker.
LD2410 is a high-sensitivity 24GHz human presence status sensing module developed by Hi-link. Its working principle is to use FMCW frequency-modulated continuous waves to detect human targets in the set space. Combined with radar signal processing and precise human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. And auxiliary information such as the distance of the target can be calculated.
This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. The farthest sensing distance can reach 5 meters, and the distance resolution is 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity in different intervals and unmanned delay time, etc., to adapt to different specific application needs.
Support GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal products.
There are 3 versions: Without Bluetooth, with Bluetooth (B version) and a C version which uses the standard pin distance. The other ones are a pain in the *ss to solder!
Got a Bluetooth version? See end of post!
When searching for examples, I noticed that many had issues getting this working. Let me be clear, it wasn’t working for me the first time. Things i’ve learned:
Flash the first initial ESPHome using a USB cable, after that you can connect the module and flash OTA
Do not use the standard Uart RX/TX, it didn’t work for me. And messes-up the logging over USB (See baudrate: 0 to turn this off)
When connecting D7/D8 and this signal gets pulled down, the wemos won’t boot. (Running wifi connections gets interrupted) This is also a sign that RX/TX is switched around!
Measure and make sure you have a good, stable 5V power to your LD2410
Here is a post about the RCWL-0516, a similar project, but this one can’t measure distances and person detection won’t work when a person is not moving.

Bluetooth:
I’ve connected this HLK-DL2410B to Home Assistant before using Bluetooth. But I wanted to get them connected using Wifi.
You can install an App on your phone to connect to the sensor when powered on. This way you can test the device, but also upgrade the firmware and make adjustments!
Just enable engineering mode and click more.
Testing another baud rate and upgrading the firmware:
Posted because I could not find a good example on the interwebs.
Below creates a virtual HA button which toggles a blinking led. (button and variables are called eprint for another function, change to something meaningful. )
