Hi!, i am going to be selling raspberry pi pc's!, they cost 200 dollars to make, How much do you think i should sell them for?

here is a pic

here is the instrucktable-https://www.instructables.com/Desktop-Pi-Hardware-Assembly/

this is not my design and do not plan on selling it until i have permission , i was just wondering what a reasonable cost would be if i do get the green light, and if people actually want it, it is really just people paying to have me print out the enclosure, and order the parts, and assemble the thing, and then finish it with spray-paints and sandpaper.

sorry if i seemed like i was trying to steal credits for it.

(update): i got permision from designer and am now able to sell.

I'm working on a RFID door lock. I have the reader set up on my pi, I just need it to trigger a servo motor so it will move the mechanism. I'm closer to the novice side of coding, and I'm a "learn as I go" type. Could anyone point me in the direction as to how to code this to happen? Thanks

I have asked this question over on the Raspberry Pi forums as well as the Raspberry Pi reddit, with no one offering me any help whatsoever. Thought I'd give this group a shot...

I have a Kano computer kit utilizing a Raspberry Pi 3b. I put Raspbian Buster on an SD card and setup everything up. No matter what I do, I cannot get audio output on the 3.5mm jack with one exception. I have tried forcing Analog Audio using raspi-config , right-clicking on the volume control and through amixer. Audio out through the HDMI interface works fine. I can get audio output through the 3.5mm jack if I force omxplayer using "-o local" but no other program will use the audio jack including VLC or system sounds and the volume control has no effect when I run it that way - even if I right-click and switch to HDMI and back. I have read that PulseAudio might be an issue, and I did try to uninstall that with no difference, but I need that installed anyway for the program I need to run - SilverJuke. I have also noticed that when I run raspi-config, the audio setting doesn't seem to be sticking - i.e. it always defaults to the default setting each time I enter that menu, whereas the other settings seem to stay where I put them. I am out of ideas if anyone could offer some advice/help....

Hey, we're a maker community revolving around 3D Printing, Arduinos & other MCUs, SBCs and other related topics! Since everyone is at home and probably has plenty of free time on their hands now we're hosting a project contest!

Our current price pool contains a small amount of cash and an OrangePI, join the contest on Discord: https://discord.gg/hkWjdZF

You can submit both new and old projects, as long as they're selfmade in 4 categories:

• 3D Printing / CNC Design
• Blinky stuff
• Nerdiest project
• Undefined (For everything that doesn't fit into any other category)

Happy making & stay safe!

Ok.... basically I want to use a Rasbpberry Pi to monitor the sound inside of a bee hive and listen for

"a sort of warbling noise that varied between the notes A and C sharp; that's 225 - 285 Hz in terms of frequency. "

and then trigger an alarm. I'm already using the Pi as a weight scale/bee counter/weather station so its already out there... this would just be an added feature. I've been following this other thread

https://www.thingiverse.com/groups/raspberry-pi564/forums/general/topic:40612#comment-2772023

and I see people mention Audacity so I went to their website & saw downloads for ubuntu & linux mint, but they say the Pi is unsupported. What build will work on the Pi? Anyone have an idea how to set up Audacity to do what I'm looking for? An insight is appreciated.

Working on a project I need the pi to listen to the audio of an acoustic guitar and give a green box on the touch screen when a prerecorded chord is duplicated correctly and a red box on the touch screen when chord aka sound is not matched played wrong.
Also, I need it to have the ability to connect an electric guitar and listen to strings to do the same thing as the acoustic with the mic only tap into the pickups on the electric to see if the correct chord was played correctly. I'm thinking of using tuner software for the comparison. Also, I want to use the 3b+ so can keep things small and no adapters for HDMI as well as giving pi a touch screen until connected to the HDMI device. Any advice on how you would build this what hat you would use and mic USB or otherwise. The goal is to try and build for under $100 in hardware. Will be designing and printing case, a touch screen wouldn't have to be huge just large enough to use until a larger HDMI device connected. Any thoughts appreciated.

Hi,
I ve been trying for a few days now to install the desktop environment on my OctoPi in order to use it with a touch screen.
Issuing the command ' sudo /home/pi/scripts/install-desktop' however fails to complete installation apparently because some files cannot be fetched.

See attached screen capture.

Any help would be appreciated.

I just bought the rbpi4 and i did all the steps on the octoprint site. i went over all the steps 10 times and tried everything. i'm not sure whats wrong. when i try to connect to it with ssh pi@octopi.local it says it can't find the host. i went over the steps an made sure everything was right 10 times and even tried burning the image over again. Nothing has worked for me and i need help please

Hi I am getting an error using OctoPi Firmware Updater Plugin. For /usr/bin/avrdude it says The path doesn't exist.
