Made a firepit from an old oildrum for an autumn barbeque party. I drilled a lot of holes in the drum to feed the fire with fresh oxygen, and reduce smoke. Worked quite well. Temperature at the bottom of the barrel was around 630°C and made the metal turn orange.

Impressive, but why not feed power from a hole in the back? That would solve a lot of cable-mess issues.

Any Bitcoin, Lightning, Nostr enthousiasts out there that are thinking of visiting WHY2025? The hackercamp has themed villages. We could apply for a village and demonstrate what's going on in Bitcoin, Lightning and Nostr.

Gl.inet routers are quite good, but to my surprise there is no model yet tgat supports eSim. Could be tgat they’re working on it, as the hardware supports it. Is a eSim USB dongle an option?

NFC payments for the bliksembier beertap firmware work quite good. What you see is an ESP32 with a PN532 NFC reader. The card is a boltcard (NTAG424). Bitcoin, Lightning, LNbits rock! https://nostr.build/av/e5314939b6d9840715ea09aee8b502c24b47c23c958e763f72bb3774ba2a1c9b.mov

Finally got boltcard payments for the ESP32 up and running. A new release of BliksemBier that supports boltcard payments is available soon! https://nostr.build/av/f5464700c4223a3fd0118380b6fc9af681d7d966915bf5ba441f7069b954ab44.mov

On the risks of deflation and the origin of the 2% inflation target of central banks. Has there ever been a deflation disaster in human history? What is the origin of the 2% target?
