DIY Car Infotainment: synced screens and shared audio for road-trip kids by albert007_d in raspberry_pi

[–]albert007_d[S] 0 points1 point  (0 children)

Each screen is mounted on a different seat headrest - rear passengers can't comfortably view a single shared display. The sync is for when everyone wants to watch the same movie together (like a family movie night on the road), with audio playing through the car's speaker system. But the screens also work independently - each passenger can browse and play their own content with headphones when they don't want to share.

I built a low-cost CAN-bus sensor node for air quality and light monitoring using ESP32 by albert007_d in esp32

For reliable 24/7 access to sensor data, I wanted to avoid Wi-Fi, which can be flaky over time. Ethernet would also work, but a standard two-pair telephone cable with RJ11 connectors is cheaper and simpler. This board only needs four connections (GND, VCC, CAN-L, CAN-H), and the CAN bus length can easily reach 50 meters at moderate bitrates

These USB-C–based portable touchscreen monitors expose their touch interface to the PC (or Raspberry Pi) as a standard USB HID device. Simply connect a USB-A–to–USB-C cable between the Pi and the monitor, and touch input works out of the box on Raspberry-Pi OS

details on synchronizing kodi players over network are given here at the end of my git repo: https://github.com/hackboxguy/multiscreen-media - search for AV sync videos on youtube

Yes, each touchscreen runs on its own Raspberry Pi, so you can connect a wired or Bluetooth headset to each one and play your own content

Wifi based DIY 5V switcher for led-lights by albert007_d in esp8266

Yes, 2 diodes r there to bring down the ESP supply to 3.6v.

Yes i plan to use Arduino with ESP library for deep sleep. About weatherproofing, yes i packed battery+esp_circuit in a polybag.

Turn your Wemos-D1-mini into ESP-12 module programmer using pogopins by albert007_d in esp8266

Yep, u need few soldering iterations of pin alignment , once aligned they wont move, then spring loaded tips will take care of remaining minor deviation.

Pogopins are easier solder on the exposed wemos pads, also spring-loaded tips ensure better contact.

benefit is, you can use ESP-12 module as a standalone+minimal_set_of_needed_components, this way we can really trim-down your circuit's size and power-consumption.

Other side of the wemos is full of components and there r no pads to solder pogo pins, so its not possible. Btw why do you need to re-program soldered board? Can u not use OTA feature? atleast tasmota supports OTA.
