| Now what can I do with 120x of these...? |

So I did my usually weekly dumpster search in the office electronics dumpster and snagged one of these: Yes I replaced the promotional video with some random clip I found. There were in total 3 large unopened shipping boxes and 1 opened box, each box contained 40x of these...Probably some HR person expressed some interest in their system and the company send 120x of these things as promotional material and they went straight to the dumpster room, quite sad and disgusting when you think about it... I was thinking about trying to accommodate the screen for a raspberry pi or something. Sure I could just salvage the batteries and screen but hey, wheres the fun in that. |

There is another thread here in this forum which precisely discusses E-waste and the environmental disaster it creates. I remember when plain Christmas Greeting cards were considered wasteful. This is an order of magnitude worse. I think, at the very least, you could salvage the batteries. |

For 120 of them, it would make sense to reverse engineer them up to the point of being able to reuse the hardware, or at least to reprogram the movie. |

From the picture the main SOC seems to be an ATJ2273B (a bit erased on the pic but looks like the most probable fit). You can find a datasheet here: https://datasheetspdf.com/datasheet/ATJ2273B.html And there seems to be a schematic using it there: http://www.go-gddq.com/upload/2017-08/17081516033140.pdf So that may help figuring out the LCD connections and such. |
