Despite its admittedly light-hearted name, the Solderdoodle Pro tackles some serious issues with current soldering irons on the market. Its 3D-printed, open source cordless design houses a Maxim charge controller and a USB rechargeable lithium-ion battery that takes three hours to fully charge, eliminating pesky cords from the picture. The tight design culminates in its ability to stay at a temperature of above 700ºF for over an hour, enough time for most garage hobbyists to complete even the most lengthy jobs with minimum battery angst. One Solderdoodle Pro will cost backers $39 USD, with the the project’s creator aiming to raise $37,800 during the month long campaign.
