The story so far: In the beginning closed Hard- and Software was created.
This has made a lot of people very angry and been widely regarded as a bad move.

Deep inside the shelves of our nearest IKEA store, hidden between smart appliances, there lies the cheap IKEA KALLSUP, a Bluetooth speaker, that promises limitless possibilities. Well, maybe not limitless. But it does allow synchronization of up to 100 devices. Supposedly at least, we did not buy 100 of them. However, it is not this promise of connectivity that caught our attention, but the curiosity about the intricacies of the internals of such a cheap device.
Follow us along on our journey into the unknown, hitchhiking on the experiences made by those who came before us, while we dive into reverse engineering of cheap, undocumented chips, analyzing firmware, and other general tomfoolery.
