Watch On
I like a little bit of bizarre tech shoved within different bizarre tech. In actual fact, it is one of many causes I write about {hardware} to this present day, and one particular person turning their rotary cellphone right into a Bluetooth headset may simply be the most effective Frankenstein’s monster-style creations I’ve seen shortly. It is alive!
As noticed by Hackaday, Jouke Waleson has had an previous Dutch rotary cellphone referred to as “1950” for 15 years and, over the previous few weeks, has turned it right into a functioning Bluetooth headset. Of their weblog, they go over the complete painstaking means of placing all of it collectively, and it is all somewhat fascinating.
They did this with an ESP32 microcontroller, which is a chip controller with each Wi-Fi and Bluetooth capabilities. Importantly, they managed to get it working in a Google Meet, having the ability to each converse and listen to unwitting colleagues. Woukes says a participant who listened to the sound high quality mentioned, “I did not know the way a lot I missed the completely different sound high quality! Stunning. We might hear you very properly, not distorted.”
After gutting the unique cellphone, and noticing the three.5 mm jack they put there for a special venture a decade prior, they checked all the person elements labored, and so they purchased a brand new stereo ADC board to transform analogue alerts and a DAC decoder. “I spent like two full days attempting and studying in regards to the microphone and I2S and will tear my hair out at some factors. With out an oscilloscope to see what’s really going this could have been inconceivable.”

When you have any want to make this, or one thing prefer it, your self, you possibly can really entry the Github with some extra data for inspiration, in addition to a YouTube video going over how precisely all of it works.
On this, Waleson turns it on, the place the cellphone flashes indicators, after which they decide it as much as exhibit Google Assistant integration. As soon as they decide it up and ask Google what’s on their agenda, Google then tells them what’s on their calendar. It can’t solely hook up with their different units by way of Bluetooth however even works as a cellphone through the use of the numbers on the system itself. It is a frankly weird little bit of ingenuity that I am keen on.
Maybe essentially the most sensible aspect of a tool that (let’s be actual) is not essentially designed to be sensible is that Waleson desires to place it on their bedside desk to allow them to depart their cellphone behind at night time. For that goal, this can be a pretty DIY venture which may be a bit extra helpful than its appears to be like suggest.
