Kroky po nové instalaci systému na Raspberry Pi

Po instalaci nového systému jsou potřeba nezbytné úpravy nutné k připojeni k jinému počítači v místní síti. 

Odstranění starého klíče SSH

Tento příkaz odstraní starý klíč ze souboru known_hosts. Poté se můžete znovu připojit.

ssh-keygen -R 192.168.20.124

Pripojeni Raspberry PI 1-5, zero jako disk k Fedoře

1. Instalace SSHFS na Fedoru

Otevřete terminál na svém počítači s Fedorou a nainstalujte balíček sshfs :

bash

sudo dnf install sshfs

Raspberry Pi Google Talk Robot

Google Talk / Chat / Messenger je lidmi běžně používá k interakci s jinými lidmi. Nicméně, jeho základní technologie může být také použit jako mechanismus pro provádění softwarových roboty. Internetové roboty, také známý jako webové roboty, WWW robotů nebo jednoduše "roboty" mohou také využívat technologii provádět automatizované funkce na webu.

BitScope – osciloskop, logický analyzátor a generátor nejen pro Raspberry Pi

Osciloskop pro Raspi

Malý šikovný a multifunkční, tak by se dal v kostce shrnout BitScope Micro vývojářů BitScope design. Přístroj disponuje vestavěným osciloskopem, signálním generátorem a logickým analyzátorem. Jako pomyslnou třešničkou na dortu je možnost provozovat zařízení na Raspberry Pi.

Dalsi teplotni cidlo v akci

Raspberry Pi se zdá ideální pro všechny druhy "fyzického" výpočetních aplikací, protože je malý, levný, s nízkým napájením a ještě více výkonný a na funkce bohatý než tradiční mikro-kontroléru.
