A Crypto Ticker For raspberry pi's

[thehodogman]

Hi all was digging around on a few facebook pages the other day with the volatility in the market at the moment i was looking for a ticker to keep an eye on some of my holdings i came accross this guys post talking about how he made a raspberry pi ticker for the 3b and 4b with a 10.1inch touchscreen thought you guys might find it usefull aswell heres the link to his repo

https://github.com/raspberrypiticker

Hope this helps you guys out its fully selfcontained on the pi from from what i can see only pulls live data

Peace out long live cyrpto

Could you send me a photo of the final result? I couldn't find anything in the link you provided.

Neat little desk toy idea, but yeah, that GitHub link looks dead on my end too, so I'm not surprised sologub couldn't find anything. If the repo got renamed/made private or it's just a typo, that's the first fix. And if you want people to actually try it, toss in a screenshot or short gif in the README so we can see what final result even means before anyone starts wiring screens and burning SD cards.

Also, tiny practical tip from building a similar "ticker on a spare Pi" thing ages ago: keep the data pull boring and gentle. Poll an API at sane intervals, cache the last good result so your UI doesn't freeze if the internet hiccups, and run it in kiosk mode as an unprivileged user. Half the "my Pi is haunted" posts come from folks running random scripts as root and then wondering why it eats itself at 3AM.

Have you checked out their releases page? Seems like they posted the image there with a screenshot. I'm not familiar with flashing Pi, but the size seems quite large, at 1.35 GB. The screenshot is still limited, though, and I don't have a Pi to try the image. There is a zipped source code on the release page, but it's just a copy of their GitHub, not the package itself as far as I can see. I'd be strongly cautious since I know little about it. CMIIW.

That GitHub account/repository looks very shady to me.
1. Some repo use GPL license, but none of them repository contain source code.
2. The text description appear to be AI generated.

Size doesn't matter if it's malicious by downloading the malware from internet.

Based on the description, the compressed file appear to be image file to be flashed rather than source code.

Had one running for a few years. LCD died and I have not gotten around to replacing it but it's probably still running just can't see it :-)

That's true, but what I'm trying to say with that post is that I'm not sure if it is common for a Pi OS to be larger than 1 GB or not. I agree that even if it's common, it can be malicious, though.

Yeah. I thought it was the source code at first, turns out it's nothingburger.

₿TClock (by Djuri) is probably the best open source bitcoin clock I ever saw.
Do you know any similar project that can work with cable internet connection to show bitcoin price, instead of wireless connection?
I don't want to use constant wifi just for ticker, and I would like to use it similar as bitcoin clock.

Exactly, don't flash the 1.35 GB image directly.

Mount it first on a clean Raspberry Pi OS
losetup -fP image.img --> mount /dev/loop0p2 /mnt

Then grep for suspicious stuff. If it passes, you can safely flash.

Most of them will work with a wired connection so long as you are using an RPi that has a network port on it.
If are using an RPi zero or similar then they are obviously going to be wi-fi only so you might have to tweak the case a bit if they are based on the smaller board.

Many of them if they cannot communicate with the outside world will show an error after a certain amount of time telling you that the clock cannot communicate with the API that it is pulling the price from. With the one I posted above that timeout could be changed by editing a couple of lines of code to put the timeout into the multiple days. I can't see others being that different. You could probably reach out to the people making them and as.

There are also a few nixie tube clocks / tickers out there, that will function as base clocks without internet but are in my view way too much money.
