For people on the go. Radio Shack TRS-80 Model 100 Portable Computer (1983). For a tiny computer this thing has a great keyboard and is loaded with ports. Even has a built in modem. #TRS80 #RadioShack #Tandy

Just posted a new video on YouTube: a faulty riveted via on a PCB from the early 1970s. It's on the digit driver PCB of a Venner TSA240 Digital Timer, and makes one display digit go blank when the instrument is cold: https://t.co/Fgm0aoNBTK

@JoshLipnik There are wall cappings and even entire buildings in Bristol (UK) made from blocks of copper slag. It's a by-product of copper smelting and very weather-resistant. Known as "Bristol Black" https://t.co/Mwk9vlT7C9
