Want: [Wayback/Archive] SMLIGHT SLZB-06 – A Zigbee 3.0 to Ethernet, USB, and WiFi adapter with PoE support – CNX Software
Startup SMLIGHT has launched the SLZB-06 Zigbee 3.0 to Ethernet, USB, and WiFi adapter with PoE support that works out of the box with open-source software such as Home Assistant and Zigbee2MQTT.
The device combines Texas Instruments’ СС2652Р microcontroller for Zigbee with ESP32 for WiFi, data transfer to Ethernet or USB, and peripheral functions such as LEDs and a button.The design is complemented with Microchip LAN8720 for Ethernet.

For all attending [Wayback/Archive] May Contain Hackers 2022 , a few things to check out:
- their blog contains new posts with exiting news: [Wayback/Archive] Weblog | May Contain Hackers 2022 – blog
- Tweeps and tweep-groups are fiddling with the MCH2022 badge already resulting in cool things like:
- The MCH2022 terrain as a gameboy map (which runs on the MCH2022 badge)
- There is a batch housing you can 3D print
- Thumb knobs for the MCH2022 badge to it is easier on your fingers (2 models)
- More software to run on the MCH2022 badge (like a CTF game)
- Doom running on the badge (that of course was just a matter of time)
- After MCH2022 there are 3 more hackercamps in Europe
More below…

After yesterdays post (which I will be editing to add some more pictures) MCH2022 badge sneak previews from tweeps that attended the Bitlair 20220709 Sweatshop (@MCH2022Camp) now a call for help:
The Badge Team needs volunteers helping them on the software side.
At the badge event, the version 1.0 firmware was flashed so the badge will function perfectly fine during the event, but it would be cool if more features are available that attendees can get when upgrading at the event or downloading from the hatchery.
There is a virtual environment to test and a GitHub projects page with open issues to get started.
See the links below on how you can help:

The MCH2022 badge has an ESP32 (with WiFi!), a RP2040 and an FPGA next to a full colour TFT LCD, buttons (including joystick!), LEDs, LiPo battery, USB-C connector, micro SD-card slot and more (see below) and SHA2017 badge compatibility. How cool is that!
There is a wealth on information for this at [Wayback/Archive] Badge.team (some 22 repositories and counting: [Wayback/Archive] Badge.team: search for repositories containing mch2022).
Good starts are [Wayback/Archive] MCH2022 badge | BADGE.TEAM and [Wayback/Archive] Software Development | BADGE.TEAM (yes of course you can write your own software for it and even distribute it through the [Wayback/Archive] hatchery.badge.team Hatchery).
Below are lots of tweets including some of the Twitter retrospect that organically grew (just like the sweatschop event) on Twitter the day after.
From the original announcement [Wayback/Archive] May Contain Hackers 2022: Presenting: The MCH2022 badge! , this is what hardware is in it

[Wayback/Archive.is] GitHub – JanDerogee/TeleJukebox: A project based on the concepts of the Wonderfoon and Arduinofoon which simplfies the design of the Wonderfoon keeping the most important music playback feature down to
a simple PCB in a small case where you plug the phone in
…
The completed project works very simple:
- Pick up the phone, you hear the “dial tone” MP3, Dial a number, you hear the MP3 0..9 playing (depending on the dialed number), When the song is over, you hear the “disconnected” MP3, You can dial another number and hear another song or hang up the phone.
- Some phones also have a button on the front. When you press this button, the phone randomly playes one of the songe 0..9 and when that song is over, it automatically plays a new song, randomly. This will allow the person on the phone to continuously listen to the music. This may be of help to those who can’t figure out how it works but love to hear the songs over and over again.
- You can configure the music folder from which the MP3s are played, you can use up to 10 different folders
- You can configure the volume of the device
- Configurations are done through the phone itself (dial 738 OR hold the button while picking up the handpiece), you hear a voice that guides you through a menu and all you need to do is dial in your settings value.
You can power this design through a USB port cable. This way the device can be fed using a simple mobilephone charger OR be connected to the PC. When connected to a PC, the TeleJukebox identifies itself like a USB-stick and you can easily modify the file without removing the card from the system. Meaning that you do no even need to open the case in order to change the collection of MP3 files. Keep in mind that when the device is in USB-stick mode, it cannot playback MP3 files meaning that in this mode it will not act like a TeleJukebox.
Music rights
Especially when using this in a professional environment. be sure the music that plays is rights free (there are music therapists for treating people with Alzheimer’s and dementia that can help you with that).
Steps, reasoning, and building instructions
A less in depth Dutch article (with 13 minute explaining video below) explaining most of the steps and all the reasoning is this multi-part one:
- [Wayback] .Build – Bouw een Wonderfoon – Bouw een Wonderfoon voor iemand anders – Achtergrond – Tweakers
It works with these and younger phones as long as they can do pulse-dialing:

Wonderfoon got more versatile
Note that the most recent Wonderfoon products got more versatile allowing more songs, warnings for taking pills, and ring-reminders based on morse code.

Cool little camera.
Absolutely not HD, but comes in very handy for instance when monitoring things from a remote location.
