Fresh hacks every day
[Collin Cunningham] over at Make recently wrapped up another edition of “Collin’s Lab” - this time around, the subject is breadboards. He starts off by discussing a common solderless breadboard, something you are no doubt familiar with. What you might not know however is how breadboards got their name.
Way back when, before there was a RadioShack in every … Read the rest
Augmented reality might be all the rage these days, but when you take a closer look at the technology, you will find that these sorts of optical illusions are not new at all.
Artist [Sebastian Schmieg] was pondering augmented reality for a bit and decided he could replicate the effect using old and obsolete technology. His creation, called “81 Points … Read the rest

It’s not seconds since the epoch, but an homage to a very expensive New York City art piece. [Jarek] took his inspiration from the Metronome art installation in Union Square.

AVR chips are convenient because you can program them in circuit at their operating voltage. That is, unless you screw up the fuse settings and they’ll no longer listen to an In System Programmer. If you find yourself facing this problem, just build this circuit on a breadboard and ‘unbrick’ by holding down the button.
The circuit seen above … Read the rest
[BiOzZ] wanted to try a different keyboard layout than the ubiquitous Qwerty, so he grabbed an old keyboard and converted it to the Dvorak setup. This was accomplished by first popping off all of the keys from the black keyboard seen above, and boy did he find a mess underneath. It was nothing that a trip through the dishwasher … Read the rest
This laser display is persistent thanks to a glow-in-the-dark screen. [Daniel] built it using a Blu-ray laser diode. As the laser dot traverses the screen, it charges the phosphors in the glow material, which stay charged long enough to show a full image.
The laser head is simple enough, two servo motors allow for X and Y axis control. A … Read the rest
