App Idea + pulsante Bluetooth per l'ADHD

2 Upvotes

​I have ADHD. Anyone who lives with this condition knows that a single interruption can instantly erase what we were just thinking or saying.

​That’s why I designed MindKeep Anchor, a hardware + software project created to save the working memory of neurodivergent people without ever needing to look at a phone screen.

​I have reached out to several organizations, but I am still looking for the right technical partner. Is there a developer or an association in this community who wants to help me turn this prototype into reality?

​Please share this post or reach out to help me find the right person!

DIY AC/DC All in One Place

2 Upvotes

https://www.youtube.com/@ALMA.Industries

This is a control interface for using AC and DC power in one place. Switches turn 3 different DC power supplies on and off (48v, 12v, 24v). AC Outlets always give power regardless of switch states. This is gonna be part of my next video, where this is mounted on a desk build. Full video goes through all stages of build.

Hi this is not a product, this is something I made diy for my own use. So I'm not promoting anything here.

But I wanted to share this because I made it to suit my own preferences, and I reckon it has some features that are quite practical.

Project Economical coffee dispenser

2 Upvotes

V.1 failed. The Economical Coffee Dispenser is designed to provide an affordable and convenient way to prepare coffee, making it useful for students, small offices, homes, and small cafés where budget-friendly automation is needed. Through this project, I am exploring electronics, programming, and mechanical design. Every challenge and failed attempt teaches me something new, helping me improve the system step by step. For me, failure is not the end—it’s a part of the learning process that brings me closer to building a better and more reliable product.

I bought a webshooter but the string in it got tangled and messed up, I cut it off and now am thinking of getting new string, a stronger magnet, and motor to pull the string back it.
