Hiking in Tirol (Tyrol, Austria) with a friend from TI. While searching for food he discovers a 43oh.com/Badge kit in his rucksack. Not something to eat, but hang on… as a serious hardware developer one never leaves the shop without some basic tools. True story.
Butan-gas (as in regular lighters) powered soldering iron rocks!
