IR Modular Piano Kit doco? ( SKU LB-00061 )

Bought three of these little kits for the kids to solder together and have a bit of a play with. The kit comes with zero documentation which means that it’s not quite clear what we are meant to do with it. Nothing online, it seems the company is out of business as their web site isn’t up anymore.

The vendor seems to have disappeared. Wondering if anyone has a copy of the documentation…
