How to use octopi with Orange Pi PC?

by jacky_joe

Hi Guys
3 months ago I used my raspberry pi 3 with Octopi to control my 3d printer and also I connected it to my webcam to do some time lapse. The thing is
recently I've received an Orange Pi PC and I'm planning to connect it to my second 3d printer but with some extra features, (even after knowing that I can connect 2 printers to one raspberry pi, but it is always good to learn new things ) and I was wondering if I can use the same .img on orange pi that I've used with raspberry pi3 before. (depending on what I know, that orange pi pc similar to raspberry pi2 since both of them have H3 chip /Quad core ARM Cortex A7 CPU -1.6GHZ), (also the img is origanally made to fit raspberry pi (1, 2, and 3)

so, is it possible?

some details, links will really help

thanks in advanced

Help with the master thesis - Search for interview partners

by Gamzec

Hello dear community,

I am a student at the Technical University of Darmstadt and in need of your help with my master’s thesis. I am examining the topic of explorative and exploitative behavior in online communities and want to understand your actions on Thingiverse and how they are influenced by your personality traits.

Therefore, I am currently looking for interview partners who are willing to tell me about their experiences on Thingiverse in a 30 to 40-minute interview.

Between the volunteers (approximately 10 participants) a 50€ Amazon voucher will be given away as a small thank you. If you are interested, I can also provide the results of my thesis to you. The interview is possible in English and in German. Your data will of course be treated confidentially and will only be used in connection with this thesis.

If I caught your interest, please sign up with your e-mail address to the following doodle list at your preferred time. Afterward, I will send you an invitation to the Zoom call. The doodle is in Central European Time, but everyone is welcome to participate. It is first come, first serve.

Many thanks in advance!

Physical Pi hookup to Anet A8

by slcloud63

I'm trying to figure out how to actually physically hook the Pi to the A8 motherboard. The only other input I see is a USB type b connector. So I guess I need a type one to a type two connector?

RFID trigger servo

by zackpollard_04

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

Need Help With No Audio From 3.5mm Jack

by rebeltaz

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....
