Bored smartphone, she made a cell phone dial extremely nostalgic
- Tram Ho
Smartphones have helped change the world, but smartphones are not always beneficial to users. Social networks, games, web, video on smartphones often distract us, reducing productivity or study.
Justine Haupt is one of those nostalgic people, and she doesn’t like smartphones. So she decided to build her own mobile phone. It was a unique mobile phone, with dials like those of 40 years ago.
Perhaps today’s 9x and 10x generations don’t even know how dial phones are, or how to use them. Although there is no touch screen or even a camera, every rotation of this mobile phone brings a feeling of indescribable delight.
Haupt shared this interesting project on her website, and she also shared electrical circuit diagrams, making details so anyone could make their own dial phone. .
Western Electric Trimline phone.
According to the website, Haupt took advantage of the dial taken from a Western Electric Trimline, a dial phone model that is smaller than many other models from decades ago.
It is attached to a homemade circuit board, with a modern mobile communication chip and a large antenna. All are housed in a case made by 3D printers. Although the size of the phone is not small enough to fit in your pocket, it is still light enough for you to hold and hold on your ear for the duration of a regular phone call.
The phone was pretty rudimentary, but Haupt had a few more built-in features that traditional dial phones didn’t have. It is a signal meter with 10 LEDs, or programmable keys to call a certain number. There is also a small ePaper screen to display information such as missed calls. Also very interesting and useful, isn’t it.
At first Justine Haupt wanted a quick and simple project.
Then she thought again and wanted to design it into a real mobile phone.
