Reddit mentions of SmartQ C307 USB 3.0 Portable Card Reader for SD, SDHC, SDXC, MicroSD, MicroSDHC, MicroSDXC, with Advanced All-in-One Design

They cost about $8 on Amazon.

If nothing else, it's still a good thing to have if you ever decide to upgrade the microSD card your Switch uses, or if you have an a Android phone crap the bed and you need to transfer data/apps, etc.

For Switch data transfer, just copy/paste all the data from your current card to your computer, pop the new card into the Switch and format it, then load the data from your computer onto the new card.

That depends on how early you want to start. There are a lot of different components at play here, but each one is using the bare minimum of each.

Personally, I would start simple with building a base Home Assistant server.

• Raspberry Pi Starter Kit $70
  
• 32gb Micro SD card $8
  
• Micro SD Card/USB Reader $8
  
  Once you have your equipment, install Hass.IO using the Raspberry Pi 3 instructions.
  
  Home Assistant does a great job of walking you through the steps. It is really easy, especially if starting with a fresh install.
  
  From here, you now have Home Assistant running and you can play around with installing all of the various components. I highly recommend taking some time to learn the basic mechanics of adding equipment.
  
  From there, I have done a ton of trial and error in JavaScript and HTML using W3Schools. My suggestion: come up with what you want to do, start small, and build from it.
  
  In my case, I wanted two separate websites on one screen. DAKBoard on the top, and my Home Assistant front end on the bottom. This told me iframe, so I started here, which allowed me to do live trial and error. Eventually, I built myself up to using Repl.it for trial and error, but that's jumping ahead.
  
  Once I got my iframes working out, I actually used Dakboard's instruction on how to build a wall display that automatically boots into a webpage.
  
  The final step is to put your new webpage on Home Assistant's built in web server. Simply create a folder "www" under your "config" folder, add your new html page there, and direct your new wall panel to it's address.
  
  tl;dr - start small, come up with a goal, and build up to it in pieces trying different things along the way.

Suggestion for you:

And a good 128 gb microSD card, maybe

Initialize the card in the bit.

Put your vacation pictures on the card every year (or whatever frequency you vacation) and put the card in the bit.

If you don't use it a LOT more, I'd be very surprised.

This made all the difference for me, and utilizes (untethered to your phone and/or camera) the very best of what the 'Bit offers.

Looking at the specs that does not have an SD card slot. You can use a USB adapter, line one of these for your card.

So the tools I purchased for my printer are:

Pi 4 is overkill, a 2 would work fine, but I'd recommend a Pi 3 for $34 cause it is better hardware and will probably last longer. I tried a PiHole on a Nano just for fun but the PiHole GUI preformed abysmally.

and don't cheap out on the SD card, splurge and get a $5 - 16GB SanDisk or something reputable. I have about 9 active Pi's now running 24/7 for years and the only problems I ever have run into are due to corrupted or failed sd cards, because I used old crap laying around my office, or the cheapo ones they put in those Pi bundles you see on amazon. All the other stuff in the bundles is fine (power, usb cables, hdmi adapters, heat sinks cases, etc) but the cards always blow.

For a Pihole all you should need is a 16GB micro SD card(8 would work, but good companies don't seem to make them anymore) a micro usb cable for power, and an ethernet cable to attach it to your router. If you don't have a laptop or something with a micro SD slot, you may need something like this for the setup process(setting up the sd card is done on a computer)
