Computers and other gadgets cram a ton of componentry onto ever more compact circuit boards. But not that long ago, electronic circuits were anything but efficiently packed onto a small green motherboard. Techquickie looks at how we got from there to here.
Voltera’s machine lets you print two layer circuit boards right on your desktop. Its plotter lays down layers of silver-based conductive ink, making circuit prototyping and experimentation crazy simple. it can even prep, heat, and reflow solder for surface-mounted components.
Electronic musicians and anyone who needs to combine audio signals will dig Bastl’s miniature mixer which provides five individual channels with up to 20dB gain each in a tiny box that runs on 4 AA batteries. It’s limited only to mono signals, but it’s still a nifty gadget. DUDE!
