ESPager replaces the radio receiver inside a vintage pager with a small Wi-Fi-enabled board. A message entered in a web browser appears on the pager's original display.

Creator Corey Harding uses an ESP32-C3 to generate the encoded signals expected by the pager and feeds them directly into the original data input. The project targets the first-generation Motorola Advisor and compatible models, and also documents integration with telephone exchange software.

TamaFi V2 is a pocket virtual pet that treats nearby Wi-Fi and Bluetooth activity as its environment. When it goes hunting, the radio activity it finds changes hunger and mood, while it can also choose behaviors such as discovering open networks or taking a rest.

Nearby radio activity is classified as calm, busy, open, noisy, or hostile. Detecting deauthentication or disassociation activity can lower comfort and happiness and trigger a glitch-like facial reaction. The current firmware is read-only and does not store SSIDs or MAC addresses. It was created by CiferTech.

Throaty Mumbo built a custom GBCTube cartridge to play YouTube video on a Game Boy Color's 160×144 display. The project progresses from displaying images and video to streaming over the link cable, then adds custom Wi-Fi-capable hardware.

The video demonstrates playback on real Game Boy Color hardware and covers the cartridge electronics, battery and enclosure built for the project.
