@thzinc pretty near, but it's not a data logger!
The mcu is an #esp8266 (a D1 Mini clone), as you said it's connected via i2c to a #PN532 -based #NFC reader. The module to the right is not only an sdcard slot support. Is a " #DFPlayer ", a sketchy module containing an #MP3 player and amplifier, controllable via #UART. Pretty limited, but I needed someting cheap, quick and dirty, and it ticks all the boxes.
The idea is building an electronic storyteller (something like https://www.myfaba.it/ or https://lunii.com/ , but without the whole closed source stack, tracking and remote bricking they bring along) for my daughter.

KaboomBox Is A Firecracker Of A Music Player

Ka-chunk. Let’s face it, 8-tracks were not that great. But the players, that’s another story. The Panasonic RQ-830S, aka the dynamite or TNT player is just one of many lovely designs th…

Updated my Plantmonitor project and got rid of SoftwareSerial, since the #ESP8266 has a second (tx-only) #serial interface, which I can use to control the #DFPlayer Mini

Ich habe vor Kurzem einen sprechenden Pflanzenmonitor erstellt!

Basis ist ein #ESP8266 mit einem kapazitativen Bodenfeuchte-Sensor, einem Bewegungssensor, und einem #DFPlayer Mini.

Hier ist die Beschreibung und der Quellcode: https://codeberg.org/rommudoh/Plantmonitor

Doku ist in Deutsch und Englisch.

Nächster Schritt ist die Integration in Homeassistant mittels ESPhome.

DIY PECS Board Uses Pictures to Communicate

One way of communicating with autistic and non-verbal people is through the use of a Picture Exchange Communication System or PECS board, which they can use to point out what they need or want throughout the day. However, the commercial versions of these boards have their share of problems -- they're expensive, and they're fairly rigid as far as the pictures go. [Alain Mauer] has created an open-source PECS board that is far more personalized, and has audio to boot.

The number one requisite here is sturdiness, as [Alain]'s son [Scott] has already smashed two smartphones and a tablet. [Alain] went with a laser-cut MDF enclosure that should last quite a while. Inside is an Arduino Pro Mini and a DF Player Mini that plays corresponding clips from a micro SD card whenever [Scott] presses a button on the 16-key copper foil capacitive keypad. This PECS board is smart, too -- it will sound a turn-me-off reminder after a few minutes of inactivity, and issue audible low battery warnings.

So far, [Scott] is responding better to photographs of objects than to drawings. Watch him interact with the board after the break.

This is far from the first thing [Alain] has built to help [Scott]. Be sure to check out this Pi-based media player built to engage and not enrage.
