Maker builds a toddler phone that can only call family members

[UnratedPhil82]

A clever DIY project gives young children a phone that only connects them to approved relatives. Hackaday reports on a toddler phone, tipped in by Allan Binder, built around an ESP32-S3 microcontroller

The ESP32-S3 acts as a USB host for a retro style handset and runs a minimal SIP client over WiFi, connecting through the parent's VoIP account on Twilio

Lit arcade buttons each speed dial one approved family member. Each button's light follows that relative's time zone, so a lit button means it is a good time to call

Calls are outgoing only, so there are no sales calls or unwanted incoming calls. Text to speech tells the child when it is not calling time and reports any network errors. The prototype case is made of cardboard, which Hackaday notes is a bit flimsy for a toddler

Using time zones to light the buttons is a thoughtful touch for families spread around the world. It gives children independence while keeping them safe. With a sturdier case, this could make a lovely gift for grandparents and grandchildren

Would you build something like this for your children? And what other DIY projects have helped your family?

Retro handsets are perfect for kids. Big, easy to hold and fun. Much better than giving them a smartphone

A cardboard case will not survive long with a toddler. 3D printing a sturdy case would be the next step. Rounded corners too. Safety features are well thought out
