Description:
The 'Thought Catcher' could replace your phone on your bedside table, leading to fewer distractions keeping you awake.

FULL STORY ======================================================================The 'Thought Catcher' is a DIY Raspberry Pi-powered device for capturing late night thoughts It has no screen and converts your speech into text, then uploads the transcription to Notion With this tool you might no longer need
to reach for your phone when in bed

If youre anything like me then youre probably familiar with lying awake in bed, mind buzzing, and thoughts coming to you when youd rather be sleeping. Thats annoying enough in itself, but its even worse when you feel compelled
to use your phone to record those thoughts further staving off sleep by looking at its lit up screen. But it doesnt have to be like that.

As spotted by XDA Developers , Ansh Trivedi has used a Raspberry Pi to create what they call a Thought Catcher, also known as the TC-01. Its a device that you place by your bed, and if a thought comes to you, then you can press a button on it and speak to record the thought.

Press the button again when youre done speaking, and whatever you said will
be transcribed by the AI-powered Whisper.cpp service, and sent to Notion,
with a beep letting you know thats been achieved. Get some screen-free sleep

So theres no need to reach for your phone, and therefore one less reason to even keep your phone by your bed, which is ideal if you tend to reach for it at night be that to record a thought or browse social media when youd
rather not.

When you wake up in the morning, youll then find those thoughts in a Notion database, categorized as an idea, task, or note, complete with a
summary-style title, relevant keywords, a timestamp for when the note was captured, and if its a task an urgency level assigned to it, as you can see in the image below. (Image credit: Ansh Trivedi)

Of course, this being Raspberry Pi-based, youd have to make it yourself, much like Trivedi has done. And as well as the Raspberry Pi itself, it also requires a physical button, a microphone, and a buzzer plus Python code to configure it.

Its also something that Trivedi is still working on, so future versions may
be improved. The full details of how to make this havent been released
either, but Trivedi says theyll share that if theres interest.

It certainly sounds like an appealing device though especially if a smaller version of it can be produced. Then after that Ill just need a waterproof one I can use in the shower, as thats the other time when thoughts tend to come
to me.
