Be your own bank. Be your own cloud.
I've been a fan of @Umbrel ☂️ for years, but their new operating system and dedicated hardware are next-level.
I created an extensive tutorial that guides you through setting up Umbrel Home, installing updates, configuring WiFi and 2FA, downloading the Bitcoin blockchain, and setting up Tailscale.

I build nodes and talk about it.
Coming up: BitAxe Tutorial
Learn how to:
- Set up the Bitaxe
- Connect to your own pool
- Connect to Braiins
- Reset the device
Online in the coming weeks.
Behold: my very own retro @mempool viewer!
I revamped this old Hanimex film editor with an LCD screen and a Raspberry Pi.
It operates a Python script that connects to my personal mempool instance on my @Umbrel ☂️ node.
Icing on the cake: it can even monitor transactions!
I created a custom Telegram bot to monitor transactions. By using the command /tx <TXID>, I can check the status of a specific transaction.
If I use the command /reset, the mempool viewer resets itself.
Components:
- Hanimex E300 (case)
- Raspberry Pi 3b (any model will suffice)
- LCD screen (7.0 Inch CLAA070MA0ACW 800X600)
Some handiwork is required to fit it (Dremel recommended).

So if bitcoin is the pinnacle of decentralization and ethereum is the ultimate centralized shitcoin, why are ‘our’ privacy solutions being shut down with the press of a button and is Tornado Cash still running.
Lesson in there.
Ok so running a BitAxe on my own @Umbrel ☂️ using @Public-Pool is fucking cool.
After a week of hashing away I have a question though: which block template am I using?
Right now I just run the software and point my node to it. I don’t really know what I’m (and what I’m not) including in the blocks I’m mining.
Does anyone have more info on this topic? Would be cool if I can further configure my pool (and block template).
Can anybody explain to me why it is so difficult to find a great NOSTR app that doesn’t make it impossible to zap with my own wallet.
I like the interface of Primal over Damus (especially for Zaps) but I can’t use my own lightning wallet (on iOS).
I’m probably missing something, so if there are any experienced NOSTR users out there: help me out.
