Why a Bitcoin Full Node? Raspberrypifullnode

[Tutorial] Build and run your own Bitcoin node on Ubuntu 19.10

I am finally doing my part and running my own bitcoin node in a small home server.
Most guides I found online were either incomplete, outdated, or explained only how to run bitcoin-qt (graphical interface). So I built a minimalistic guide with the starting point of Ubuntu 19.10 to run the latest Bitcoin core release (v0.19.0.1) as of today.
If you have an old laptop (raspberry pi, NUC, etc even better) a reliable internet connection, and ~ 500Gb of HDD (USB external drive are just fine), you should consider running a node. It's fun, you will deepen your computer knowledge, and you will be supporting the network.

Putting the fun back into FUNgibility (full node, JM, and yield generator)

I'm new to BTC (<1 year) and not a blockchain guru, but I started stacking sats as an alternative investment. I'm not retiring off my crypto anytime soon, but its enough value that I want to increase my BTC security and competency (currently stored in an exchange wallet like a pleb). I was on the verge of moving everything into cold storage, but then I found JM through Googling keywords along the lines of "bitcoin income generation."
I've been studying up on JM for the last 48h, and decided to: build a full node, create a JM wallet, start running yield-generator. Even though it sounds like income will be zero or close to zero, I hope it will be a fun learning project.
I'm going to go out right now to buy some hardware components and will continue to update this thread after each milestone. I'm expecting to learn a lot through this process so I am making this post so that others can learn from my inevitable mistakes, and a place to ask for help if I run into problems.
Stay tuned for updates!

Update 1: Shopping completed. I'm going with a Raspberry Pi with 4GB of ram, 0.5TB external SSD to store the blockchain. I bought a couple of accessories to help me set up the environment (keyboard, mouse, lcd, usb hub). I also bought a pimoroni fan shim to make sure nothing overheats. I'll be using my windows laptop for initial setup as well. Next step is hardware setup and software environment (Raspian, fan service controller, and hdd partition).

Update 2: Good success with the hardware portion of the project. After I got my OS running I immediately nuked my SD card by running fstab without reading man first - classic. I wasted an hour trying to recover, then reflashed my OS and got everything running. First I got the fan service controller working, then formatted external hdd for ext4 (came with ntfs from the store), setup firewall and tor, and installed bitcoind. The next step is to finish allowing my blockchain to sync, and then test all functionality before starting with joinmarket. Results: https://imgur.com/a/sE1f1ap
Update 3: It is taking a long time to fully sync to the network so I decided to install but not configure JM during this lag time. I successfully installed JM, but I decided to call it quits for today before editing joinmarket.cfg. I was hoping to be completely done today but I lost several hours due to my own incompetence. I should have enough time during the week to continue this project, so I will check back in tomorrow. Does anyone have advice on joinmarket.cfg settings for tor? Current status: https://imgur.com/1Tp7kJN
Update 4: After a long delay due to lack of time during work, I finally got everything working 100%. Due to privacy and security advice from friends, I will not be posting any specific information about my JM wallet, but it is up and running and able to submit and participate in coinjoins - very exciting! I'm going to start learning about payjoin next. Thank you to Joinmarket creators and community for helping me through this process... I will continue to provide new content in the future with any significant updates to either joinmarket code base or to my own setup.

Raspberry Pi & Block Eruptor Advice

Not trying to make a ROI, trying to participate in bitcoin with a power-efficient-as-possible bitcoin miner (I assume rpi is best) with USB block eruptors. Any advice I should know besides the multitude of posts already here and /raspberry_pi? I plan on installing Raspbian and using CGMiner, but I've seen a few other OS's, so OS and mining software advice would be huge I plan on getting a USB Powered hub eventually, but first the raspberry PI would act as a full-node. Also! if anyone is trying to get rid of their old usb block eruptors, I would be huge

Friendly friends, I'm a noob but like to run a full Bitcoinnode on raspberry pi. I barely know linux, so I just used tutorials step by step. Because of one of these I loaded the blockchain on a usb harddrive (formatted for Linux ) with my Windows pc. I also did everything neccesary to install bitcoin full node on my raspberry. How do I make the bitcoin node use the data on the external ... Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network. Special Cases. Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety ... It helps keep the Bitcoin network secure and reduces the trust you are giving others when using 3rd party Bitcoin Explorers or Bitcoin Light Wallet servers. They can track you or give you false information, reducing your security.

How to run a Bitcoin Lightning Node on Raspberry Pi. This simple guide shows you step by step how to setup, run and monitor your Bitcoin node. To help with scalability and performance of the Bitcoin network they have introduced the Lightning Network. This allows "off chain" transactions. This guide walks you through the steps in running a full Bitcoin Lightning Network Node on a Raspberry Pi ... If you plan on running more than one Bitcoin miner at the same time, it is best to use a powered USB hub. Take into account the power rating as mining will need a lot of power, as much as one mp per miner. With your USB miner attached to your Raspberry Pi, let’s get everything installed.
