Fresh hacks every day
This column of messages was printed with Escherichia coli. That’s the bacteria better known as E. coli which can cause so many problems if it makes its way into our food. But the relative size and the fact that this strain was engineered to glow in the dark makes it a perfect candidate for Bio Printing. We find it even … Read the rest
When it comes to making PCBs at home really quickly, there’s not much to improve upon with [Ryan]‘s bodged up Epson printer that prints an etch mask directly on a piece of copper clad board.
Like most of the direct to copper PCB printer conversions we’ve covered ( 1, 2, 3 ), [Ryan]‘s build relied on an Epson … Read the rest
[Nirav] painted this masterpiece by hand… with a little help from a computer. He calls it the semi-automatic paintbrush because you do need to move it over the canvas by hand, but a computer decides when to dispense the ink.
He’s using a piece of hardware we looked at back in September called the InkShield that got a boost from … Read the rest
Here’s a photovoltaic cell that can be printed onto paper. The manufacturing technique is almost as simple as using an inkjet printer. The secret is in the ink itself. It takes five layers deposited on the paper in a vacuum chamber. But that’s a heck of a lot easier than current solar cell fabrication practices. In fact, is sounds … Read the rest
Like all of us, [Ryan] is tired of waiting for board production houses. To reduce some of that turnaround time, he modded an Epson inkjet into a PCB printer. The Instructable of his build is extremely thorough and it looks like he’s getting some quality boards out of his project
The build started off by disassembling an Epson C86 … Read the rest
[Nicolas C Lewis] is churning out inkjet print head shield kits for Arduino. If you’ve always wanted to label or brand objects as part of a project this greatly simplifies the process. Using his all through-hole design, an Arduino can print at 96 dpi. At first we had trouble figuring out what we could use this concept for, but … Read the rest
At this very moment, unseen radio waves are bouncing off almost everything that surrounds you. Emitted by everything from radio and TV stations to cell phone networks and satellites, these waves are full of unharnessed energy. That is, until now. Researchers at the Georgia Tech School of Electrical and Computer Engineering have been working diligently to harness this unused energy, … Read the rest
