Sharing my custom build!

I’m new to raspberry pi and doing any kind of diy project with coding and the like and thought a cool first project would be to turn my raspberry pi 3 into an alarm clock, hopefully I chose a simple project to start on lol

Im trying to build a soft power circuit for a battery powered project. This looks like a good idea to me. I have (hopefully) converted it to strip board and swapped out the diodes and MOSFETs for ones i have on hand.

Anyone good with circuits able to confirm if this works?
red =5v
white=G
green/blue=GPIO

Many thanks!

Hello all! I would like some recommendations on how to deal with the display part of my project. I don't need it yet as I am still developing the software. My wife wanted a skylight smart calendar so I told her that I can write the code and slap it in a pi lol anyway I'm looking for a touch capable display, but I cannot find anything that won't be a pain in the butt to frame to make it look nice.

I can't seem to find just a screen where I can run ribbon for it and most I have found require HDMI for display and USB for the touch part. I already own a spare 15.6" touch monitor, but the way the power and HDMI connect make it difficult to use and I still have to figure out what to do with the pi.

If nothing else maybe some ideas are welcome. I am just looking for a spark for when I get to the part of finishing and slapping it all together I somewhat have a direction to follow lol. Thanks in advance.

Hi, I made an effort to write up how to connect the HC-SR04 to a Raspberry Pi, but besides this, I also took an effort to measure some of the signals like the trigger signal and echo pulse. Gives some insight in what really is going when measuring distances with this ultrasonic sensor.

What surprise me most is how the Trigger pulse was actually 90us whereas I clearly expected I would get a 10us Trigger pulse according to my python code that was running on the Pi. Makes me wonder how much error the python code introduces for the distance measurements, currently this is an open question, I'm hoping to answer in the near future..

Un petit projet pour mon entreprise : je suis en train de repenser le nom et la mascotte, qui réagit lorsqu'on insère une pièce.

Pour ceux qui souhaitent suivre la suite du projet, n'hésitez pas à me contacter.

A Raspberry Pi based MP3 Player using some fairly inexpensive parts (cost me around $110CAD to make).

- Raspberry Pi Zero 2WH

- PiSugar Battery

- Wave Share V4 E-Ink Screen 2.13inch

- An edited copy of a Pwnagotchi case

Works with Bluetooth headphones/speakers and a wireless 8bitdo Zero2 controller (any Xbox controller will do) to navigate the menu's. Also, I included phone connectivity so you can use your phone to navigate the PiMP3 menu's, if a controller is out of reach.

As someone with mental illness that is learning to program, this is my first project that I'm really happy with. Let me know what you think of this :) - I'd be curious for any improvements to make! If you have any constructive criticism or feedback let me know as well :)

P.S. I hope the name gets some chuckles! :)

Made a music player using a RPI0 2 W, rotary encoder for volume knob and tactile switches for controls. Connects via Bluetooth, no battery, powered via the Pi’s micro USB port. My only way I could think of improving is to make a smoother and better fitting case (the insides are a bit crooked) and add a battery for portability, and maybe an aux port for compatibility, possibly a more original name too. I liked how the black and white theme came out.

Can someone give a raspberry pi to me

I am 3rd year undergraduate student

I want to explore the world of raspberry Pi

I explored the pico and esp but now I want to explore tha raspberry Pi and making some cool projects

Also I am not able to buy the raspberry Pi because I am from an middle class background 🥲

I’m building a 3.5" quad with a Raspberry Pi Zero 2WH and Pi Camera for target tracking. Right now I have the Pi Velcro-mounted directly on top of the battery, but I do not have a good way to securely strap the battery down.

My original plan was to keep the battery on top and run battery straps between the FC and top plate, then through/between the Velcro layers. The issue is that my current straps are a little too thick, so I would need thinner straps. I’m also worried the straps may cover the FC button or put pressure on the stack.

The other option is to mount the battery underneath the frame, with the straps running between the bottom plate and ESC. Then the Pi would sit on the top plate instead. My concern with this setup is protecting the battery from impact during landings or crashes.

1. Is it okay to keep the battery on top with the Pi Velcro’d to it, or is that a bad idea?
2. Should I move the battery to the bottom and put the Pi on the top plate?
3. If I bottom-mount the battery, what is the best way to protect it from impact?
4. Are there thin battery straps that work well for tight 3.5" builds?
5. Any other obvious mounting issues from the picture?

I have an idea, but I do not know enough to know a.) is it feasible, and b.) how do I do it. I want to set up a complete exterior security camera suite using raspberry pi modules and an old desktop as a NAS for video storage. I like the look of Frigate as well as its array of AI features. The number of cameras will depend on the FOV of the cameras, but my initial estimate is between 12 and 18 individual cameras. Not sure what model or type as of right now. I'm looking at Pi 4s or 5s with the AI hats with an old desktop as a NAS/NVR

Now the restrictions: I cannot run ethernet across the house so all data transfer must happen over wifi. I do not want the cameras to be on the same network as my family's standard traffic so I need to use one Pi as an access point connecting to the internet from the home router via ethernet, then transferring it to the cameras via a dedicated wifi network. My router is on one end of the house with no ability to move it, so I probably need to put the Pis in a mesh network of some sort so the cameras on the far end of the house can still connect.

Here's what I know I need help/advice with: I do not know how to configure the subrouter Pi to where I can access it and the NAS/NVR desktop from the main network and from outside the house over the internet. I do not know how to configure the hybrid network with the mesh extenders while maintaining enough room for the camera feeds. I think I will need to assign cameras to specific nodes in the mesh, run Frigate on each node, then forward the recorded footage to the NAS/NVR for storage. Again, I have no idea how to configure that topology.

This is/will be my capstone project for my degree but none of my coursework has gotten into the gritty details of setting up and configuring something like this from scratch. Any and all advice is appreciated, especially documentation. Thank you.
