Intro:	==='''''Classy''''' the Raspberry Pi Computer and Media Center=== :This PC is a [https://en.wikipedia.org/wiki/Raspberry_Pi Raspberry Pi] 4 Model B [https://en.wikipedia.org/wiki/Single-board_computer Single-board Computer]. It has 4 GB of RAM and 480GB of [https://en.wikipedia.org/wiki/Solid-state_drive SSD] storage. (Unlike most Pi's, which primarily use lower capacity [https://en.wikipedia.org/wiki/SD_card SD cards.]) The choice of using a SSD over a SD card for storage is for more for stability of the system rather than providing a lot of data space. :This computer's name is ''Classy'', as is <code>classy</code> is it's [https://en.wikipedia.org/wiki/Hostname hostname]. :A powered 4 port USB 3.0 hub is provided for users for connecting additional USB peripherals, commonly such devices as a flash thumb storage or portable hard drives. :There are no [https://en.wikipedia.org/wiki/USB-C USB-C] type ports available. An adaptor will be required to use this type of connection. [[File:Rppress example 2021.png|thumb|150px|Raspberry Pi Press website featuring some of their publications that can be found on this device. Late 2021.]] :[https://store.rpipress.cc/ Raspberry Pi Press]'s rich library of computing and DIY maker books and magazines have all been downloaded ''[all to date as of 2022-05-08]'' and is available in the <code>student</code> user's Bookshelf directory. <blockquote>''(Select: Raspberry Menu (purple berry icon) from the task bar, choose "Help", then click on "Bookshelf".)''</blockquote> :Or navigate to <code>/home/student/Bookshelf</code>. ---- <br /> <br />
Rules:	*Keep It Classy, Be Excellent! * **Entertainment / Personal Use: While someone else is hosting a scheduled class, or while the space is being used as someone's refuge from noise from the rest of the facility (i.e studying), or when folks participating in [[Craft_Room|Craft Room]] activities of this ''shared space'' while not desiring distractions - such personal use would be rude and definitely Not Keeping It Classy! <blockquote>'''''Routine Personal Use or seeking this computer to be the source of your primary computing for your project would not be welcome.''''' Perhaps the [[Media_Lab|Media Lab]] Zone is better suited for such needs.</blockquote> However [https://www.i3detroit.org/wiki/Category:Special_Interest_Group Special Interest Groups] (SIGs) and [[Zones|Zones]] looking for a platform to host material for their classes, curriculum, and/or demos is highly encouraged. *Conserve energy and turn the computer off when not in use. (Further instructions below.) *''Classy's'' home is in the Media Zone.<!-- Perhaps include an example image here. --> Please make sure ''Classy'' is always where they belong. *Avoid using the already fully allotted USB ports on the Raspberry Pi / Argon40 ONE M.2 case itself. A powered USB is provided for connecting peripherals. The single USB-C port on the case is for system power supply only. *In regards to the main board's microSD card reader: Having a normally accessible card reader (for a Raspberry Pi SBC) is not the case with this unit, because of the Argon40 ONE M.2 enclosure requires taking apart and removing screws from the plastic base to access it. '''''Unnecessary opening of this case is discouraged. The on board SD card reader is unavailable.''''' Unless needing access for maintenance / repair of the computer itself, please use a USB based dongle SD card reader instead, when making disk images or general data access with SD cards. *'''''Don't forget to sign out of your personal web services like email or Slack.'''''
Instructions:	=== Access === [[File:Classy pi powerbutton.png|thumb|150px|Location of the power button.]] :'''''To Power Up the Raspberry Pi System:''''' ::*You may need to use the [[Sceptre_55in_4K_UHD_TV#Powering_On|TV remote]] to wake the screen. Click the red power button at the top of the remote. It takes about 12 seconds for the panel to wake and you should see a blue LED light at the middle bottom of the bevel, after turning on. Change the TV's input to HDMI #3, using the HDMI button near the bottom of the remote. ::*The case is well labelled as to where the power button is, only needs to be pressed once. A red LED will light at the lower front of the case should turn on. :'''''Login:''''' ::User: <code>student</code> PW: <code>KeepItClassy</code> === General Use and Operations === [[File:Powered_4port_usb_hub(focus).png|thumb|150px|Powered 4-Port USB 3.0 Hub connected to Classy.]] :Use the 4-port powered USB 3.0 hub to connect USB based peripherals (Data storage devices, game-pads, etc.). Each port has its own power switch, which lights up blue when activated. ''(View full image at the right to see an example.)'' :Support for exFAT has also been added for those with storage drives using this file system, common to Windows users. === When Not in Use === :'''''To Safely Shutdown the Raspberry Pi System:''''' ::*Close all open applications. ::**Then shutdown: <blockquote>''Select: Raspberry Menu (purple berry icon), select: green "Walkout" icon, choose "Shutdown" from the menu and the unit will turn itself off after a moment with the red LED in front of the case turning off.''</blockquote> ===Advanced Use=== [[File:Raspi argon40 gpio (edited).png|thumb|150px|Raspberry Pi 4 Model B in an Argon40 ONE m.2 Case with GPIO (General-Purpose Input/Output) pins exposed.]] :This case allows for access to the RasPi's 40 Pin [https://www.raspberrypi.com/documentation/computers/os.html#gpio-and-the-40-pin-header GPIO] (General-Purpose Input/Output), which can be used for demos of sensors, LED lighting, or other maker oriented projects. :GPIO provides a variety of alternative functions based on various technologies such as [https://en.wikipedia.org/wiki/Serial_Peripheral_Interface SPI] (Serial Peripheral Interface, often pronounced as 'spy'), [https://en.wikipedia.org/wiki/I%C2%B2C I²C or I2C] (Inter-Integrated Circuit, often pronounced as 'eye squared cee'), [https://en.wikipedia.org/wiki/Pulse-width_modulation PWM] (Pulse-width Modulation), and other [https://en.wikipedia.org/wiki/Serial_communication Serial Communication] methods (i.e. TX and RX). <blockquote>''Users whom are proficient with GPIO use & that have a general electronics safety mindset *and* have the ability to fix / replace a broken RasPi, within a reasonable time frame, are welcome to use this feature of the system.''</blockquote> :The GPIO is accessed by removing the cover. Magnets hold the cover in place. ''(View full image at the right to see pin labels.)'' <blockquote>(Default setting is that GPIO pins are *not* activated. This can be changed by using <code>sudo raspi-config</code> with an elevated privileged user. ''Additional configuration may also be necessary.)</blockquote>
