For the elderly, new technology items are often too difficult to use, especially with touch screens and tiny buttons on them. This is also the reason why Manuel Lucio Dallo, Twitter nickname mrcatacroquer, created the Yayagram – a homemade machine that allows his 96-year-old grandmother to send and receive voice and text messages via Telegram application without having to touch the touch screen.
Instead, the machine’s operations were done through physical buttons and even print paper so that his grandmother could read the message more easily. In his post on Twitter, Dallo detailed the structure and how it works.
To send voice messages via Telegram, his grandmother would have to connect to the recipient in “phonebook” – only seven people were stuck with different colored tapes for easy identification.
To send a message, your grandmother would have to plug the cable into the recipient’s name, then press and hold the record button and speak into it through the built-in microphone. The message will then appear on the recipient’s phone like a regular voice message. When Yayagram receives the text message, it will be printed to paper thanks to a thermal printer built into the machine.
When it received the text message, the machine would print it out on thermal paper so that Dallo’s grandmother could read it.
The heart of this machine is the Raspberry Pi 4 board, running on Python and many third-party software libraries for the above operations. He also emphasized the openness of Telegram compared to WhatsApp and other messaging applications is the reason he chose this app to send and receive messages.
Talking to The Verge, Dallo said, the reason he built his machine is because of the current blockade in Spain. His grandmother is 96 years old and lives with his parents in Burgos but is unable to meet her children and grandchildren. “Most of our grandparents are living outside of Burgos and because of Covid’s mobility restrictions we are unable to visit them.“Dallo said.
Moreover, Dallo added that his grandmother has a hard of hearing and as a result, it is often difficult to listen to voice calls and video calls. But with Yayagram, his grandmother can call or receive texts on her own without the help of others. “It helped her create bridges of communication with her children and grandchildren who were unfortunately far away from her“Dallo said.
As an engineer at SCM Plastic Software, Dallo created this amazing machine
Thanks to Yayagram, his grandmother can manipulate and communicate with her descendants without the help of others.
