I was thinking of using a Rasberry Pi module and a laptop replaceable touch screen as like the touch screen would I be able to hook up the Rasberry Pi to it and would it be able to work. Any advice or recommendations would be well appreciated.

I made a grid controller called Mystrix 203 System

It is a feature-rich, open-source, very high-quality grid controller with an in-house OS for many smart features. On top of that, I worked hard to make it into scaled production and made the price very affordable (compared to other small-scale controllers)

The smart OS can launch different apps to turn the device into different use cases. like a MIDI controller, drum pad, stream deck, dice, board game, lighting panel, etc. People can also build their apps with C++ in an Arduino-style API or Python in the next major OS version. I envision it to be something like flipper zero but as a controller.

I want to build a community around this project. People have already been building a lot of cool apps, features, and even their own hardware based on the project. I think people here will be very interested.

You can learn more about the device at the 203 System site

There's a new Project Matrix wiki for feature and development (Still a work in progress and I need your feedback) Project Matrix Wiki

Hey hi hello lovely community!

This is my first truly diy project, and it came about cause of a need of mine that I find very few companies are enacting.

The idea is simple, a power bank that can stay plugged in all the time and act as a desk charger, and later be removed and become a power bank. I was thinking of a battery charge limiter to make sure leaving it plugged in doesn't ruin the battery and a 3d printed case.

Would love if you can help me get started/show me some useful resources! Thanks a bunch!

Hi, everyone. I have a problem right now: my laptop has an old, low-quality network card, and I sit quite far from the internet router. I have a WiFi antenna lying around, and I need your help to connect it to my computer in some way to get faster speeds how would i go about doing this.

Thanks, everyone!

Hello everybody. I need a little help with a job I'm doing. What I need is a cheap night vision wifi camera with low capacity. However I should be able to see the video on my computer without a third party application. Because in the future I will make an app and the video from the camera will be received on the cloud. I bought the esp camera and I think it's great, but it doesn't have night vision. And I am very confused what to do. IP cameras for commercial use I think are locked and do not work for me.

I am building a power bank, using 8 18650s that are actually 18690s because there 69mm long.

Each battery is 3.7V 3600mah and there is 8 of them. How do I charge this through UsbC, what wattage or voltage.
Would the wiring diagram consist of a 4 cell BMS, connected in series to 2 of each battery, the bms connected to solar panels (what voltage would these be?)
BMS connected to power output power bank module and USBC input board. (what amperage/wattage should this be?)
Thanks

Hey DIY tech enthusiasts! I’m currently in the conceptual phase of an ambitious multi-console project, and I’m looking for advice and insights from anyone who’s done something similar or has experience in this area. The idea is to integrate the internals of various gaming consoles (from OG Xbox to Xbox Series X, and PlayStation 1 to PlayStation 5) into a custom-made Ironwood case, with a Raspberry Pi as the central control hub. Here’s the plan so far:

Project Overview:

	1.	Custom Ironwood Case: The case will house only the internal components of each console, stacked vertically with space for cooling and cable management. The Nintendo Switch will have a custom dock on top and will operate independently.
2.	Raspberry Pi as Control Hub: The Raspberry Pi will manage power switching, HDMI output switching, and controller pairing through a custom menu interface. The idea is to select a console from the menu, and the Pi will power it on and switch the HDMI output automatically.
3.	Unified Controller Setup: To reduce clutter, I plan to use Xbox Series X controllers for all Xbox consoles and DualSense 5 controllers for all PlayStation consoles. The Pi should dynamically map the inputs based on the console selected.
4.	Multiplayer Support: The system should support up to four controllers simultaneously, allowing for multiplayer gaming across all consoles.

Questions & Potential Technical Roadblocks:

	•	Controller Compatibility: Is it feasible to use modern controllers (like Xbox Series X and DualSense 5) across older consoles like the OG Xbox and PS2? Are there adapters or software solutions that make this possible without significant lag or compatibility issues?
•	Raspberry Pi as a Relay System: Has anyone here used a Raspberry Pi to relay controller inputs dynamically across multiple consoles? If so, what’s the best approach for minimizing latency and maintaining stable Bluetooth connections with multiple devices simultaneously?
•	HDMI Switching and Power Automation: For those who’ve built similar systems, what’s the most reliable method for automating HDMI switching and power control using a Raspberry Pi? Are there specific HDMI switch boards or relay modules that you’ve found effective?
•	Input Mapping Software: What software would you recommend for dynamically mapping modern controller inputs (Xbox Series X and DualSense 5) to older consoles? Are there tools that support quick profile switching and managing multiple controller configurations efficiently?
•	Cooling in a Wooden Case: Since I’m using Ironwood, are there specific cooling or airflow considerations I should keep in mind when stacking several consoles inside a dense wooden case?

I’m still in the planning and theory phase, so any insights or suggestions on potential roadblocks would be incredibly helpful. If anyone has taken on a similar project or worked with multi-console setups, I’d love to hear about your experiences and what worked for you.

By the way, I don’t enjoy typing out long texts, so I used AI to help draft this post. Thanks in advance for any advice or tips!

Hi me and my friends are working on a project of making "pop rocks" and is needed to mix a water sugar mixture heavily at high pressure (around 60 atm, 700 psi)

Obviously plastic (PET) bottles can't withstand that pressure so we're thinking of CO2 fire extinguishers and as I checked out they can hold that pressure, but the problem is with mixing as the capsule has to be airtight

Is there any mechanism we can use? Any ideas that could help?

I recently got a Siemens fridge (model KI81RAFE1). There is this little "knob" on top op the door (https://imgur.com/a/lvCYJO2), which I am wondering what function it has. I cant seem to find anything about it, spare parts etc.

Truthfully, it is getting in the way of a cupboard door above for our current project, and i am wondering if its safe to trim it down a bit.

Thanks!

Pretty self explanatory, I broke a tv, took out the lcd screen and stuff. I’m essentially left with a light box I’d like to use as a grow light, but the tv turns off after 5-10minutes due to inactivity, any suggestions on how to bypass the auto off feature by breaking the tv even more somehow? If you couldn’t tell already I have no experience with tech, if this isn’t the right place for the post please direct me to the correct place, thanks!

In this Arduino Tutorial you will learn how to build a water level indicator that triggers an LED and a buzzer when the water reaches a certain level. The system will indicate the water level inside a container and help prevent overfilling by triggering an alarm when the container is full. Checkout full Video:
