This article discusses the post-SIGNAL World hackpack v3, a device that was given to every attendee at the SIGNAL conference. The device allows users to experiment with coding and artistic creativity. To claim the device, users must follow specific steps depending on whether they claimed it at the conference or not. The process involves removing the SIM card from the device, which can be done by gently prying out the battery lead and rocking the antenna connector out of the socket. Once the SIM card is removed, users can reinsert it into the device to activate it. The device uses standard 2.54mm header spacing, making it compatible with breadboards, and can be programmed using the Particle platform. Users are encouraged to experiment with coding and come up with innovative applications for the device.
