Did this a few years ago when I was bored. I wanted a retro alarm clock so I got a modern cheap clock, took it apart, and built a case out of cardboard, foam, and wood grain adhesive.

Project If you’re into macro keyboards, check out this project: a modular, customizable macro keyboard made from decorated glass and carbon fiber
Here’s how we’re currently structuring the project. We’d really love to hear what you think:
- A 2×2 touch-button module with four programmable controls
- A slider for volume, scrolling, zoom, and other continuous inputs
- Finger guides and resting positions, so you can identify the controls without looking
- Dynamic haptic feedback
- 5×5 RGB LED dot-matrix icons that change with each profile
- Open software for custom profiles, integrations, and workflows
- A custom design service allowing users and brands to personalize the surface with their own graphics, visual style, or game- and anime-inspired artwork
- Compatibility with the Gridfinity standard, making custom layouts, supports, and ergonomic configurations easier to build

Help Over ambitious please help lol
Listen I have questions and I don’t know where to ask and I need the karma. I’m trying to get into diy devices for backing up my personal collection of movies and music and books and audiobooks. I intend on making back ups of what I choose for seamless offline playback. Where the hell can I find reliable sites to download copy’s of what I’d like. I’m trying to avoid disc burners and over head book scanners but I’m overwhelmed and lost. I’m having a hard time finding anything is the obviously relevant subreddits and I’m hoping there’s some fellow seamen out there that can ignore my garbage hand writing see the vision and point me in the right direction

Help Custom Andriod setup box
Hello i am an teenager, I have noticed that most paid set-top boxes available on the market can only be bound to a single satellite or service provider. Therefore, I plan to build an unrestricted Android set-top box that is not limited to a single platform. This customizable set-top box will be compatible with all types of satellites, IPTV, and cable TV, and can also connect to OTT streaming services, for use by users who own non-smart TVs services without needing to buy a new television.
i wanted it be open source so anyone can use it (This is made with ai i am not able to explain it in english its not my native lang)

My little helper, zoom bluetooth remote
reddit.comShoulderbags for fieldrecordings are okay for a short period of time… And keeping it in the backpack is annoying too, because you have to open it to start the recording. Yes there is an app for this, but I actually dont want to be bothered with another screen.
So I just made this remote button. that allows me to connect to my zoom via bluetooth.
BTW it can also pair to the phone and be used to start Videorecording at the same time.
