I recently bought a Raspberry Pi kit that comes with a power supply + case + heatsink + 16 GB class 10 + Raspberry Pi 3 Model B kit, and I would like to know if this model can handle a private discussion forum.

and that this project has been going on for a long time and my friends and I in the WhatsApp group were thinking about how having only one group on WhatsApp is very boring and monotonous, so someone came up with the idea of creating a forum on a network called Qannima and I chose the Onion network for this, and that is when I bought this kit.

But remembering that this project is private and will never be public outside the bubble because of the Raspberry processing that can't handle too many people logged in at once, and I'm afraid it won't hold up since it only has 1GB of RAM, and like my friends and I like to share a lot of images, and if the six of us are online at the same time and each makes a post with an image, do you think it will crash?

and making it clear that this project is for legal purposes and the name I chose was 4ever and it's just for us to chat more comfortably and have our own space on the vast internet and I would like to know if a Raspberry Pi 3 Model B can handle a project this big without crashing or freezing too much and I would also love ideas on what I can do with it if you have any.

Hey r/Kuwait, wanted to get some advice from people who've bought tech hardware locally.

I've been trying to get a Raspberry Pi for some personal hobby projects and experiments at home. The cheapest I'm finding it here is more than 20 KWD, which feels pretty steep for what it is. On top of that, older models like the Pi 3B+, Pi Zero, etc. are almost impossible to find locally.

A few questions:

\- Is 20 KWD a fair going price for a Pi 4 in Kuwait, or are there cheaper options I'm missing?

\- Does anyone know specific shops (in Salmiya, Hawalli, or anywhere else) that stock Raspberry Pi's or similar boards?

\- Any tips on importing one cheaply? Which online stores ship to Kuwait without insane fees?

\- Has anyone tried alternatives like Orange Pi or Banana Pi here? Are they easier to find and actually worth it?

Just looking for something affordable to tinker with at home. Any help appreciated!

Hi all,

I'm wondering if anyone can recommend a suitable hard case (similar in style to a peli case) that would fit a Raspberry pi + 5 inch Elecrow screen with room for a very small bluetooth keyboard? Ideal internal dimensions would be about 16 x 9 x 3 cm. The best I have found so far are Game Boy travel hard cases (which close with a zip), but I would like something a bit more rigid/waterproof. Anyone have any recommendations?

Been working on this for a few months. AR glasses are either $700 or locked down. Wanted something open and cheap so I built one. I would really appreciate comments on your genuine feedback, don't worry criticism is also accepted!!!!

How it works:
ESP32-C3 drives a 0.42" OLED. A 90° prism redirects the light upward into a piece of teleprompter glass — the same semi-reflective glass used in TV studios. That overlays the image on your view of the world. Whole optical chain costs under $5.

Right now it can:
Turn-by-turn navigation arrows and notifications over BLE from your phone. Full day battery on a 500mAh LiPo. Clips onto any existing glasses frame.

BOM:
ESP32-C3 + OLED $6.90 , prism $1.50, teleprompter glass $0.90 , 3D printed housing $1.20maybe less, misc $1.50 = $13.80 total

Still testing daylight visibility — that's the biggest unsolved problem. Everything else works.

Putting firmware on GitHub under GPL v3 and hardware files under CERN OHL v2 later on, making it open source.

What would you build on top of this? And also, do you think it would be reasonable to spend approx 30-40 euros on this? Been thinking of making some money on the side, being a student, just want to get some feedback if there even is a market for this.

I'm working on a project in that I'm using raspberry pi 4 and gps + compass module ublox 7m.

And I connected a raspberry pi 4 with my mobile hotspot so I accessed the raspberry pi from my laptop.

Initially it is working fine, but after the completing the work, when I shutdown the raspberry pi 4, then pi doesn't connecting with the mobile hotspot, I tried power on and off, Even I add a switch to properly shutdown the pi 4, but that won't also work.

I have to boot the entire pendrive from the raspberry pi imager, after the complete fresh boot, it starts working,

But the same after some interval of time, it loses connection again, every time I tried wpa_supplicant.config suggestion but it didn't work also.

Until now the boot the pendrive at least 8 times, and done the code from the scratch.

If anyone from you guys have any suggestions please tell me I really need that now.

Hi everyone,

I'm completely new to all of this, coding, Raspberry Pi, electronics, all of it.

A friend gave me a Pi because I wanted to automate some work messaging. That idea ran into WhatsApp's automation rules and didn't work out, so I'm now looking for a better use for the Pi rather than giving it back.

The board is a Raspberry Pi 4 Model B (4GB RAM) running Raspberry Pi OS Lite (64-bit), and I have the original Pi Camera Module v1 (Rev 1.3, 5MP).

A bit about me so suggestions can be relevant:

• I help run a chess academy (operations, scheduling, communication with students and parents).
• I also manage racket sports at a multi-sport facility (badminton, pickleball, squash bookings and events).
• I'm preparing for a competitive exam over the next ~5 months, so anything around study tracking or focus is interesting too.
• Honest disclaimer: I don't write code from scratch, I use AI to generate and explain it, and I'm learning as I go.

I'd love ideas that fit any of these:

• Genuinely useful for the academy or sports facility.
• Helps me learn programming or electronics along the way.
• Could potentially earn a bit of money.
• Or just a rewarding project that builds skills and feels like a win.

What would you build if you were starting from scratch? Appreciate any suggestions.

hey, i'm a 15-year-old founder with a team in singapore building asirive cortex — smart glasses for visually impaired users.

the problem:

- commercial options (OrCam, eSight) cost $2,500-3,000+

- most visually impaired users can't afford this

- existing solutions often miss cane-aware hazards (overhang, stairs_up, incoming_fast)

- most solutions are providing assistance but not navigation independence (navigating around unfamiliar/familiar places without asking another person from help) - Info from SAVH online meeting

the solution:

- RPi 5 + Hailo-8L edge AI + 5-layer routing hierarchy

- $186 actual BOM, $250 retail target

- cane-aware hazard perception (overhang detection, stair warnings, fast-approaching-object alerts)

- hybrid edge-server (local AI fallback + cloud AI)

validation:

- 3 sessions with SAVH (Singapore Association for the Visually Handicapped)

- real visually impaired users tested cane-aware features and real-time navigation

- YIA 2026 shortlist (TKKYIA, Singapore)

what i'm looking for:

- feedback on UX from visual impaired users + caregivers

- thoughts on cane-aware vs broader hazard issues

- open to collaboration if u work in this space

links:

- asirive.com (the company)

- https://github.com/Asirive/Asirive-Cortex (open-source code)

- stardance (devlog)

would love ur honest feedback — even if it's "this is dumb, here's why."

I'm wanting to build a wrist mounted cyberdeck for a cosplay and it rains allot where I'm at. I'm wanting to keep it protected from rain because I dont wanna have to keep replacing the hardware. Any advice?

is it good? can it read ntfs drives easily? can it play basic formats [mkv, mp4, avi] and read subtitles both inside and outside the files? is 4gb of ram enough?
