  • Lightning wallet for ubports

    Bitcoin is about being in control of your money. For this to be really true, all the components have to be trustable. It is worth nothing if the application is fully open source, when it is run on a compromised platform. On the desktop this is easy. Linux distributions have been well supported, and more […]

  • Lightning operated chocolate arcade

    After the Covid lockdowns are only a faint memory, conferences are back again. Last October I was at the Lugano PlanB Forum with lots of familiar speakers. The talks were good, but not as technical as I would prefer. And last month I was at the Swiss Bitcoin Conference in Kreuzlingen. The talks there were […]

  • Creating proof of reserves for an Electrum wallet

    In my last post I promised to write about how you can produce a “proof of reserves” for your own wallet including hardware wallets. So, here we go. First you need an electrum multisig wallet that involves at least one hardware wallet. I won’t go into the details of how to construct this. Recently I […]

  • No internet at the Dolder Grand

    Today was our wedding anniversary. We usually celebrate this with a meal in a nice restaurant. Last year we went to the Swiss Chalet in Merlischachen. It was very nice and delicious. The reason we went there was that they accept payments in Bitcoin. So I decided to make this a tradition. Thing is, The […]

  • a decade of accepting Bitcoin for paragliding

    Today marks the 10th anniversary of an important blog post. It was the announcement that I started accepting Bitcoin for paragliding tandem flights. I had interest in the nascent internet currency for a couple of months prior to that. And I felt that what was missing were places where people could spend their coins. Only […]

  • Bitcoin Advanced Course by 21lectures

    Last week I attended a Bitcoin Advanced Course that was hosted by 21lectures. Lucas who is also the president of the Bitcoin Association Switzerland initially wanted Jimmy Song to teach his Bitcoin courses also in Switzerland. But when that didn’t work out, he decided to build the classes himself, with the help of great quality […]

  • Run and fly with the XXLite2

    Before I participated in the rollibock trophy in Fiesch last October, I thought my paraglider equipment was fairly lightweight. The glider is a regular Mac Para Marvel, but the Advance Lightness 2 harness is optimized for weight as the name implies, as well as the accompanying backpack. With helmet, gloves, sun glasses, flight computer and […]

  • Generating solar electricity at home

    After I switched to an electric car, I started to care much more about where the energy we consume comes from. With petrol and diesel you don’t really have that option. We are in a comfortable situation that we have some small hydro electric dams nearby. Thus all the electricity we use at home and […]

  • Spending Bitcoin while charging the car

    When I go some place new, I always check out what Bitcoin accepting venues there are. I usually try to prioritize shops that accept crypto currency. When I drive some place far away, I have to charge the car on the way. No big deal, usually I can eat, drink or go to the toilet. […]

This years tour will take place from June 8th to 16th and is titled “Green Technology Tour”. We enter the trophy as Team Bitcoin with a big BTC logo on the frunk. The tour will […]
