Raspberry alternativ  

RE: Raspberry alternativ

Hi, I have never tried it with other fruits. PrusaLink will work on any Linux machine, but you would have to install it yourself. So far, it involves git cloning the projects and installing them through pip. If you want, you can try following the readme in the Prusa-Link repo https://github.com/prusa3d/Prusa-Link

When cloning please try and clone the 0.7.0 RC1 tag, or instead download the source code under the 0.7.0 rc1 release (again, for both the sdk and prusalink)

I wish you good luck and am open to helping if you hit a wall trying to install. Any feedback on the readme install instructions eill be appreciated.

Just a quick closing note. The readme is primarily meant for developers. We hope to simplify the install process in the future.

RE: Raspberry alternativ

Can't speak to Prusa link/connect but Octoprint works OK on Pi Zero 2W and they are cheap as chips. Perhaps Tojik might comment.

RE: Raspberry alternativ

Do you have a cheap source for a Pi Zero 2 W? Currently they cost around 50€ or more.

RE: Raspberry alternativ

I wish it would be like that. The truth is, a new RPi Zero 2 W scalps around a 100$ on eBay and there aren't any new ones to buy https://rpilocator.com/ . This is why he's asking for alternatives. We have tried validating our image against a Banana Pi, but my understanding is it didn't work, so the only way would be to install it on the desired system yourself.

RE: Raspberry alternativ

Ouch, I had no idea. That is outrageous.

RE: Raspberry alternativ

I have been watching the Great Pi Shortage, as I use them in all kinds of projects and applications.  They are available, but the scalpers are demanding several times list price.

The so-called drop-in alternatives that I know of, all which are more expensive than the original Pi series, are the Banana Pi, the Potato, and the Asus Tinker.  Disclaimer: I have used none of the above personally.

For smaller projects, I've gone to the Arduino compatibles, mostly the various Adafruit Feather series.  These are not too shabby for simple bit-banging projects which do not need the full OS or network connectivity.  They are easily programmed in both c/c++ and Python.

For the couple larger projects which don't require hardware i/o lines I've gone to (jail-broken) ChromeBox machines.

I've always kept a few Pi Zero boards on hand for projects and I'm glad I did, as I have two unused ones for when I need them.

I sure hope the Great Pi Shortage eases up in the near future.

RE: Raspberry alternativ

I've been using Raspberry Pi 1 model B rev 2 (which has the same stats as the original Pi 0) plugged in via USB and they work totally fine.  No lag whatsoever.  I have 2 x MK3S+ with that setup with no issues.

I was lucky and was able to find these boards really cheap because they are really old, but are good for Prusa-Link

RE: Raspberry alternativ

I did now order two Zero 2 W for 60€ each 🤣

RE: Raspberry alternativ

None of the dealers I have contact with have had any Pis for some time. 

RE: Raspberry alternativ

I think you are going to have go with OrangePI or another brand.  

RE: Raspberry alternativ

Do you (or anyone) have any actual hands-on experience with the Orange/Banana/whatever Pi as opposed to the original Raspberry Pi, specifically as to how drop-in compatible they actually are?

RE: Raspberry alternativ

I have experience with Banana Pi and I just bought an Orange Pi.  I will post my experience soon.  I just need some time to test it with Octoprint.

RE: Raspberry alternativ

Right now I'm mostly curious as to which OS you loaded on the clone boards (RP-OS? Ubuntu? what?) and if you noticed any incompatibilities between the clones and the originals.  I'm mainly interested in the Pi 3 and/or Pi 4 compatible boards, as I do have a few Pi Zero boards laying around.

My last project which I would have used a larger Pi, had it been available, I ended up using a jail-broken used ChromeBox.  This is physically much larger than the Pi 3/4 so I would like to know if the Pi 3/4 size clone boards are a good choice for future projects.

RE: Raspberry alternativ

Raspberry PI OS and Ubuntu. 

RE: Raspberry alternativ

Can you use a raspberry pi4 with the GPIO header connection (make your own cable)?

RE: Raspberry alternativ

yes, just be sure to connect the right pins. There's serious rpi frying potential when connected wrong

RE: Raspberry alternativ

To a certain extent, the various RPi boards are somewhat forgiving, since they do use some self-healing 'resettable' fuses, but those do have limits.  If your Pi appears to die, let it sit an hour or so.  It may come back to life.

I've personally 'bricked' a Pi 3 in one unfortunate breadboard error.  🙁

RE: Raspberry alternativ

I am testing several alternatives.  I have a banana pi, Orange PI, Libre, and one from Big Tree Tech.  There are trade offs of each, but it is better than not having one.  

RE: Raspberry alternativ

I'm just not sure there is any real advantage using the GPIO pin vs using USB?  PS: I'm using old Rasp Pi 1 model B Rev 2 via USB and having no issues.

Maybe @tojik could provide insight as to any advantage/disadvantage with any of 2 methods above?
