It is with great pleasure that i can finally share this project with you!
When I first started with home assistant I knew nothing about electronics automations or any of this stuff. I followed tutorials and did what I could following Bruh at first until he mysteriously disappeared… if you’re out there Bruh hope you’re well… Then Dr.Zzs, digiblur etc…
Learning from all them, came in handy when I injured myself, pushing me to buy a bunch of sensors and gizmos and put together my version of the Bruh multisensor… but way cooler 
So I thought i’d share back too.
I give you Artoo:
I bought a Die cast R2D2 and gutted it with a dremmel.
I took out all the unnecessary metal, but leaving enough to attach a servo with some glue.
it was tedious but it came out great.
In the dome i added a bunch of tiny leds in such a way that the little probes that stick out are functional.
I also added some RGB leds.
There’s a bunch of sensors: a BME 280, an mpu6050, a resistive light sensor on the top of his head, a capacative touch pad on the front (some copper I smashed soldered to a wire poked through the body), a DF player and the SD card , loaded with R2D2 sound effects and Star wars sounds & songs, is accessible from behind without having to open up the body, a PIR sensor that I placed in the dome in the same spot where there is a lens like indentation (i used a black PIR cover cut to fit), and last but not least a SERVO to move his head!!! (it took me a year to figure that one out… so many issues lol but now you can make one!)
There’s also a micro usb female jack embedded in the back, so that you can power him and flash him using a usb cable; I think you can also get tracks to play from usb but i haven’t tried that yet.
All this powered by a Tinypico ( i tried several boards this was the winner)
I have a tiny battery since there’s a BMS and monitoring pins on the pico, I pulled from a vape device that i’m still trying to figure out, not sure if it’'l make the cut… we’ll see…
I built this with esphome:
Still working on the automations and stuff, but since I finally got it all to work properly -and all the features lol (still testing the battery pins tho), well… here it is!
Enjoy!

As a note, Logger seems to have to be turned off otherwise no-go. I’ve tried many configurations even without the DF player, and it won’t work with logger (but who cares now that i got it to work!!!)
Also, i recommend creating some sort of disconnect on the TX and RX lines connecting to the DF player so that when you flash the Firmware the DF player doesn’t interfere. reconnect after flash, and then subsequent flashes can be done OTA.
Let me know if you’s like to know more and i’m happy to share.
Also happy to try out some automations if you’ve got em!!!
