I've recently bought an interactive R2-D2 by hasbro from 2002. Sadly the main board has stopped working, there's no short on the board. So I need to find a way to give it a new brain and reuse parts to restore functionality as much as I can.
Here's a better demonstration video with the three dance modes. Would love to get the sound files somewhere.
R2-D2 has some fancy lights in his head, but here with the 40% scale they resulted to holographic stickers instead. I might change that with some fibre optics (lichtleiter for ebay) or replace it with an OLED - not sure yet! both displays come together to 225 LEDs.
From other projects I've learned about drone parts, known as BECs that convert LiPo voltages to 5V and most often 12V. I want to modify the HTPDB-XT60 module so it will convert to 5V and 6V instead, so I can use a 2-cell LiPo pack.
To control the motors I will use a DRV8838 single motor driver for the dome and a DRV8833 dual driver for the leg wheels
