Hello world! I want to share with you a device I made, its name is “Yayagram”, a machine that helps our beloved elders to keep communicating with their grandchildren . How? Let me open a thread to give you all the details of this contraption.
First, why Yayagram? Well, “Yaya” means “Granny” in Castillean, a warm way to refer to your grandmother. And, I use @Telegram to send and receive messages, so merge both words and you have the… #Yayagram!
The Yayagram has two features:
● Send voice messages via Telegram by just pressing a button.
● Receive Telegram messages and physically print them on thermal paper.
To send a new voice message you need first to choose the destination grandchild, the selection is made using a Jack connector, like the #cablegirls used to do!
Recording a new voice message is similar to the regular #Telegram app, but here all is analog. Keep the record button pressed. Talk. Release the button and it’s sent!

Dallo used a Raspberry Pi 4 as the brain of the device. It’s coded in Python using several third-party libraries. Other components include jack connectors, LEDs, cables, a printer, a mic, and a button. He plans to publish an instructables project soon with all the build details.
Take a look at a couple photos of the device below and hit the link below for the full details.
