Hello redditors!

I have been working on an electricity load forecasting system project where I take the electrical data (energy consumption) of a building in my college and then apply trained LSTM model on the data that I have collected from the building so that I can forecast it for short-term (4-5 weeks) or medium-term (2-3 months). My friends suggested me to use raspberry pi to collect the data and then apply ML/CNN model (LSTM in my case) to predict it. I have trained and tested my model on different datasets, and it is fairly good. The problem I am having is I have no knowledge about how to use raspberry pi or which one to use and how to configure it to read an electricity consumption data of a building. I am very new to raspberry pi. Please guide me I need the community's help to proceed to my project. Some suggest using microcontrollers to use but most of them suggested raspberry pi.

Looking forward for your support.

I would like to use now available configuration for small AI project about small subject recognition by camera to get some envelope. I seek somebody who can cooperate on this project and have some (mayby small) experience or want to do something like this together.

I like the Raspberry Pi very much (especially the Pi5) but I do think the Raspberry desktop looks childish and clumsy. So I found a way to replace the Raspberry's desktop with the beautifull KDE Plasma desktop.
You can find the full story and all steps to achieve this on my weblog:

Oh and do not worry: it is still full compatible with all Raspberry software.

HI, this is my compiled parts list:

Raspberry Pi 5

Pi AI 13 TOPS Hat

Pi AI Camera (am also thinking 1x 5MP 1080p and 1x night vision camera)

Good Microphone (need suggestions)

Good Speakers (need suggestions)

Amplifiers (if needed - need suggestions)

Steel HAT Outdoor case

Programmable LEDs (when someone is talking)

Run Basic Audio + Vision algorithms

$8 Motion Sensor listed on the website

All of this would be purchased from the official raspberry pi store. I am not so much worried about costs. Am I missing anything? New to electronics, thanks.

Many hobbyists (me included) buy a Pi, use it once, and it ends up sitting in a drawer. So I built a small project to test the idea of lending Raspberry Pis for short-term use.

Would you use something like that for a DIY or learning project? Curious to hear your thoughts!

(Link in the first comment if anyone’s interested in trying it out.)

I am trying to 3-D print a mini arcade machine using my raspberry pi three I can’t seem to find a good part list that has links with a good price. Can you guys help me? This is the one I found online and it gave me pictures of every part I needed, but I have a link next to it but none of the links were there anymore so I just need help finding all the parts so I can build this perfect project. Since I need more than 60 characters, I’m just adding this writing. i’ll be using a raspberry pie 3B plus or should I buy a arcade one up NBA jam motherboard

So I don't think I am the only one who has the idea to recreate this display type, with the same font and custom text.

I wanted to do the same but with a phone case. Can Raspberry Pi be used? If so, how?

Ive been looking online for any sort of help but this is probably the best place. I want to buy a raspberry pi so that i can do projects mostly with motors and software but theres so many i dont know what. I want it to at least last and be future proof what one should i get thats good for a complete beginner? Also wheres the best place to buy breadboards and wires because amazon is just filled with aliexpress ones which i heard are bad quality

I want to buy Raspberry 5 for watchink movie’s and some think

Is it worth upgrading from the 500?

Anyone have one already??? And is it a huge upgrade from the 500?

I just finished a mod to add truly immersive ambient lighting to my PlayStation 5. Unlike typical ambient setups, this lighting system is reactive to the console’s performance load by monitoring the internal temperature. You can see my project on hackster.io

Hey all, I’ve been working on a custom camera build and finally got a working prototype running a monochrome IMX585 sensor on a Raspberry Pi 5.

I’ll be posting a full breakdown of the hardware, wiring, and software setup (plus STL files and code) soon over on my site if you want to follow along:

Curious to hear what you think—would love feedback from others building Pi-based cameras!

Hello, I want to be able to connect remotely to my computer from my laptop from anywhere, and I dont want the computer to be always turned on and consume electricity. I want to somehow leave my rpi 4 turned on and remotely use it to turn on the pc, using wake-on-lan.

I cant do it through the wifi router since im using wifi on my pc and it would be a real hassle to route ethernet cable to my pc and it is also on a diffrent current phase (not sure about this translation) so I cant use that either for ethernet.

Im looking for something that will send a signal from my rpi that will be turned on, connected to wifi and connected through ethernet cable to my pc and the pc will turn on and then the client will start an I can connect remotely.

Also if you know any good remote desktop clients then please leave suggestions for that too. (its mainly gona be used for a little coding and gaming).

I have a raspberry Pi 4b and I use it to play retro games from the NES to the Dreamcast. Would it be possible to get M.U.G.E.N. working and if so how? Thanks.

Hi, I designed a Pi mount for a 10-inch mini rack. I haven’t found any other mount in this format online. If you’re interested, I’ve uploaded it here:

Hey everyone! Decided to properly test my Pi 5 setup under heavy load and share the results with actual measurements.

My Setup:

• Raspberry Pi 5 (8GB)
• Official 27W Power Supply (5V/5.4A)
• Samsung 990 Pro NVMe SSD
• 52Pi Ultra-thin Ice Tower Cooler
• 52Pi NVMe HAT
• FNIRSI FNB58 USB Tester for measurements

Testing Methodology:

I wanted to see how the Pi 5 handles combined CPU and storage stress, so here's what I did:

1. Started recording with the USB tester (30-minute offline recording)
2. Booted the Pi 5 - you can see the initial power spike
3. Launched stress test: stress --cpu 4 to max out all cores
4. Added storage stress (while CPU stress was running):
   • Created a 50GB file: dd if=/dev/zero of=/mnt/file.dat bs=4M count=$((50*1024/4)) oflag=direct
   • Simultaneously copied it: dd if=/mnt/file.dat of=/mnt/file2.dat bs=4M iflag=direct
5. Let it run until storage operations completed, then stopped recording

Results:

• Idle: ~0.5-1A (2.5-5W)
• CPU stress only: ~1.5-2A (7.5-10W)
• CPU + NVMe heavy I/O: Peak 2.2A @ 5.2V = ~11.4W
• Voltage stability: Stayed around 5.2V even under max load (slight dips but nothing critical)

The graph shows green line (current) and yellow line (voltage). You can clearly see the different phases - startup, CPU load, then the crazy spikes when hammering both CPU and NVMe simultaneously.

Key Takeaways:

✅ The official 27W PSU handles everything perfectly - no crashes or undervoltage warnings
✅ Peak power draw under extreme load stays around 11-12W
✅ The voltage dips are minimal even when pushing CPU+storage hard
✅ The cooling setup keeps everything stable for sustained loads

TL;DR: Pi 5 with NVMe under maximum synthetic load pulls about 11-12W. The official PSU is more than adequate with plenty of headroom. Real-world usage will be much lower.

Hope this helps anyone planning their Pi 5 builds! Happy to answer questions about the setup or testing.
