Hello everybody! Gzuuus here, how is everything going here?

As an enthusiastic hardware developer, BTC and LN lover I'm trying to develop some prototypes to build a functional PoS that uses LN and allows you to receive payments easily anywhere.

I closely follow great contributors to this ecosystem like Ben arc with his amazing projects (https://github.com/arcbtc), the incredibly useful guides of @DarthCoin (Hi Darth👋) and all those people who are creating and expanding this beautiful free and open source community.

Inspired by the recent and brand new Bolt card from the guys of coincorner, and Ben's great LN PoS FOSS project (https://github.com/arcbtc/LNPoS) I was wondering if there is any project that allows you to have NFC functionality on a LN PoS so we can develop our own NFC cards based on LNURL-withdraw and play around a bit.

The idea is that it is a piece of hardware independent of the mobile phone that follows the principles of the standards proposed and collected by David Coen in his github repo (https://github.com/theDavidCoen/LNURL-withdrawPOS) to create an ecosystem where we can all use our NFC cards and spend our satoshis freely.

I think Ben's project is a good starting point (https://github.com/arcbtc/LNPoS) since it is based on ESP32 as core and nowadays there are many modules to read/write NFC cards like the PN532 module (https://www.nxp.com/docs/en/nxp/data-sheets/PN532_C1.pdf), the question would be how to integrate it in the LNPoS to read the LNURL-withdraw of the NFC card and process the payment.

I look forward to your comments and responses, let's expand this and keep buidling ⚡⚡

I see that here there will be an exodus or at least an exploration by some tw users to alternative platforms, very curious that stacker.news is becoming very active ... even more curious that much of its traffic comes from twitter (https://plausible.io/stacker.news)
I would love it, it feels much more comfortable here :)

Hi!👋 @Gzuuus here!

I'm studying to develop personal btc nodes, it's a path full of mysteries and many surprises, it's amazing to know this technology from its core. I discovered SN a few days ago, I connect through GetAlby, a delightful experience and I think it can be a good platform to create valueXvalue. 
I wanted to start here saying hello, Hello! and sharing the different steps and the experience of setting up a btc node in case someone can use it, a kind of diary that I will write as I set up the node and discover the paths of personal sovereignty.

Let's start with one of the most crucial decisions: **the hardware.**
Studying I have come to the conclusion that one of the best platforms to mount your node is a barebone pc better than a rpi4 or sbc due to the fragility of the connections with the storage media (SATAIII vs USB connections in many cases), besides giving you more power with a relatively similar level of consumption between the barebone and the rp4 (~10W).

List of hardware I will use to assemble the node:
-Intel NUC BOXNUC7CJYHN2 Intel Celeron J4005
-Crucial SO-DIMM DDR4 2400 PC4-19200 4GB CL17 (x2)
-WD Black 2.5" 1TB SATA 3

The case is to make a node as balanced as possible between price and reliability.
We could write a lot about the philosophy, responsibility and resilience behind setting up a node, but we'll leave that for another post. ;)
Greetings to all! see you around :)

BTC study path. 1.Greetings and Personal Sovereignty, setting up a complete BTC node. (Hardware)
