Last October I was at the <a href=\"https:\/\/planb.lugano.ch\/planb-forum\/\">Lugano PlanB Forum<\/a> with lots of familiar speakers. The talks were good, but not as technical as I would prefer. And last month I was at the <a href=\"https:\/\/swiss-bitcoin-conference.com\/\">Swiss Bitcoin Conference<\/a> in Kreuzlingen. The talks there were even less technical, but the conference was all in German. That was new for me. I only recently discovered how big the German speaking Bitcoin community grew. So far the Bitcoin community that I was involved was more English speaking. A good percentage was also Swiss people, but since there are also a many expats, the main language has always been English. But that&#8217;s not what I want to write about here.<br>The conference was a FIAT free zone. Drinks and food was all paid with <a href=\"https:\/\/en.wikipedia.org\/wiki\/Lightning_Network\">Bitcoin Lightning<\/a> thanks to the payment terminals from <a href=\"https:\/\/lipa.swiss\/\">Lipa<\/a>.<br>At the conference there were some industry booths. These are always interesting to explore. One that was particularly interesting was <a href=\"https:\/\/www.bischof-automaten.com\/\">Bischof vending machines<\/a>. They presented an industry grade vending machine with a Lightning upgrade (prototype), that they actually plan to bring to production. They also sold toy <a href=\"https:\/\/shop.lnbits.com\/product\/bitcoinswitch-lightning-grabber-machine-kit\">LN Candy Arcades<\/a> with a <a href=\"https:\/\/github.com\/lnbits\/bitcoinSwitch\">Bitcoin Switch<\/a> kit. I had to get one of these!<br>Back home I flashed the micro controller and configured it. And I modified the candy arcade to operate by the relais from the BitcoinSwitch instead of the coins. It is fairly easy to do, but it is at such a high level that it&#8217;s more difficult to diagnose if things don&#8217;t work, than working at the lower level that I usually prefer. But since everything was already so well prepared, I did the whole thing without diving into the code. The machine is now in the office at <a href=\"https:\/\/seba.swiss\">SEBA<\/a>. So far only few colleagues installed a lightning wallet and grabbed some chocolate. It works most of the time, but I found out that the <a href=\"https:\/\/legend.lnbits.com\">LNBits demo instance<\/a> is not always so reliable. And I also found out that it is the most difficult to grab some <a href=\"https:\/\/www.chocolate.lindt.com\/our-chocolate\/our-brands\/lindor\">Lindor<\/a>, when the ground is fully covered with one layer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After the Covid lockdowns are only a faint memory, conferences are back again.
