Electronic Alchemy’s unique 3D printer can output multiple kinds of filaments in a single print, including conductive, resistive, capacitive, and semiconducting ones, allowing it to print out objects with built-in electronic circuits. It’s got eight retractable extruders, so objects can combine up to eight different materials.

Known for their in-depth automotive repair manuals, Haynes is now making a series of kits which let you build your own rudimentary gadgets, including a retro LED handheld game, an analog synthesizer, a working amplifier, a film camera, an FM radio, and a Simon-esque memory game.
Every electronic device we rely on uses printed circuit boards. Scotty Allen of Strange Parts takes us inside the PCBWay factory in Shenzhen, China to see how the pros do it in volume, accurately, and with miniscule parts. If you’re interested in how they make the circuit boards themselves, watch this.
From Siri, to Google, to Alexa, voice based systems are pretty much ubiquitous these days. But how can a computer speak so many different words so well? The 8-Bit Guy looks back at the early days of digital speech synthesis, and how that led us to today’s innovations.
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!
