Ordered a nice portable soldering iron online the other day, just got it in the mails. Looks really neat, powers off a laptop psu (18-24v) . Has a usb connector, turns out, it's a mass storage device, you can change the settings with a text file, you can upgrade the firmware, firmware is opensource, people have made alternative firmware for it, schematics are available and you can change the bootup logo...
I am like 'wat?'.
TS-100, now my favourite soldering tool...
