The tinyTelsa musical Telsa coil from oneTesla

The folks who successfully crowdfunded a DIY singing Tesla coil kit last year have taken to Kickstarter again to bring a smaller version into production. Like its older and bigger brother, the tinyTesla shoots out bolts of artificial lightning while playing MIDI music using the electricity itself. It looks like that polyphonic MIDI version of Danger High Voltage by Electric Six might just come in handy after all.  Read More

The pioneering integrated circuit has an estimated value of US$1 million and $2 million

If it weren't for the microchip, your smartphone would be size of a building and need its own power plant to work. Thanks to the integrated circuit and its modern incarnation in the microchip, electronics are a bit easier to carry around than that, and this week, Christie’s put one of the very first integrated circuits up for auction. Designed and constructed in 1958 by Texas Instruments, it's one of the three earliest "chips" ever made and went on the block with an estimated value of up to US$2 million.  Read More

Chibitronic stickets lets you add circuitry to art projects creating an interactive greeti...

"Cute circuitry" is not a term you hear often – if at all – but it could be used to describe Chibitronics, which is a crafty merging of electronics and paper. The system combines familiar adhesive stickers with electronic components, such as LEDs, sensor circuits, and even a programmable microcontroller, to create a play set that educates while adding some flash to one’s works of art or otherwise mundane birthday cards.  Read More

Researchers at ETH Zurich have created ultra thin, clear and flexible circuitry

Researchers at the Swiss Federal Institute of Technology in Zurich (ETH Zurich) have created clear, flexible electronic circuitry that is so thin it can sit upon the surface of a contact lens, or be wrapped around a human hair. The research, led by Dr. Giovanni Salvatore, could ultimately be used for implantable medical devices. One such potential application suggested by the team is a “smart contact lens” that could monitor intraocular pressure for glaucoma patients.  Read More

Circuit Scribe uses silver ink to draw circuits

A new company called Electroninks is seeking to make DIY electronics child’s play ... literally. Circuit Scribe is a roller-ball pen filled with conductive silver ink that enables the creation of circuits by simply drawing them.  Read More

Georgia Tech's printed circuit technique could make it cheaper and faster for professional...

Researchers at Georgia Tech have developed a new technique to print advanced, ink-based electrical circuitry on a desktop printer. After about US$300 in equipment costs, the researchers were able to print arbitrary-shaped circuits on resin-coated paper, PET film, and glossy photo paper with silver nanoparticle ink.  Read More

A flexible polymer circuit, shown here, could someday be replaced by a cheap and flexible ...

Given the low costs and extensive applications that could be possible with flexible paper circuit boards, we've seen many ideas for their production, from printing with silver ink to embedding chips within paper. Now, however, scientists have developed an elegant method for selectively changing the very nature of the paper itself into conductive graphite. Unlike polymer-based flexible circuits, these paper circuits are, ironically, able to withstand the high temperatures generally used in the production of electronics.  Read More

Self-healing chips recover from complete laser-inflicted transistor destruction (Photo: Je...

Although you are fairly unlikely to start zapping your gadgets with high-power lasers any time soon, scientists are already hard at work trying to make electronics immune to such cruelty. In another in a series of self-healing electronics breakthroughs, a team of scientists from the California Institute of Technology (Caltech) demonstrated chips capable of dealing not only with laser-inflicted physical damage but also with far more common ailments such as aging, power fluctuations, changes in temperature or load mismatch.  Read More

Educational electronics kits like the one from Minty Geek are a great introduction to the world of circuit building and electronic tinkering, but are perhaps a little too basic for more advanced hobbyists. Three MIT students are currently enjoying enormous success on the Kickstarter crowd-funding platform with a DIY Tesla coil kit called oneTesla that can make artificial lightning sing ... well, erm, play music from a MIDI source. Now where did I put that polyphonic version of This Town Ain't Big Enough For Both Of Us by Sparks?  Read More

The new chemical chip can control the delivery of the neurotransmitter acetylcholine, enab...

While the silicon chips found in the electronic devices that we rely on every day are built around the flow of electrons through circuits, with the development of an “integrated chemical chip,” a doctoral student in Organic Electronics at Sweden’s Linköping University has created the basis for an entirely new circuit technology based on the transmission of ions and molecules.  Read More
