fixing a bad motivator

putting a new brain into an interactive R2-D2 from 2002

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.

fixing a bad motivator | more lights

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.

fixing a bad motivator | Power section and motor control

2022-05-15 20:45:48

R2-D2 seems to run on 3 voltages:

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
