Fresh hacks every day
Sometimes security doesn't need to be overly complex to be effective. Instructables user [1234itouch] recently built a simple laser tripwire alarm that can be mounted virtually anywhere, complete with a keypad for disarming the device. He mounted a photo cell in a project box, along with an Arduino and a 12-button key pad. A laser pointer is aimed at the photo cell from across a gap, which … [Read more...]
Grab that stack of old optical drives you have in the corner and get to work building this laser engraver. [Groover] is taking a no-nonsense approach to the build and we think it is just simple enough to be accessible to a very wide audience. The physical assembly uses sleds from two optical drives. These are mounted some angle bracket. Since lasers cut at one specific focal length, there is … [Read more...]
[dev_dsp] wanted to try his hand at creating a purely analog implementation of multiple synchronizing fireflies powered by a single battery and built from off-the shelf, through-hole components on inexpensive protoboard. In theory, even your local Radio Shack should still carry all of this stuff. He was obviously inspired by [alex]'s fireflies that we've covered in the past, but he wanted to see … [Read more...]
[Nigel's] been trying out a series of designs and materials to make his own bounce flash. He set out on this mission because most of the images he used flash on ended up washed out with dark shadows. The flash add-on seen above seeks to curb the harshness of the direct light but shielding the subject. What you see above is just a couple of pieces of paper. [Nigel] put together a template so … [Read more...]
[FallDeaf] bought a Lol Shield, and after making all sorts of blinky displays, he thought to himself, “What in the world can I use this thing for?” In a really slick fusion of hardware, software, and the power of the Internet, he has created what he calls, “Lol Shield Theatre”. The idea goes something like this: You visit his site, and create your own “movie” by drawing on his … [Read more...]
Though some people differ on what exactly a “hacker” is, there is one thing that can be said for certain - this global community of tinkerers, experimenters, and hobbyists we belong to is one of big hearts. Through our various projects and tutorials, we lead by example - sharing knowledge and offering help whenever we can. You would be hard pressed to find something that could exemplify this … [Read more...]
Looks like someone figured out the algorithm that Microsoft uses to generate unique codes for their alternative currency: Microsoft Points. We were always a bit baffled by the need to do this sort of thing (Disney dollars, tokens at arcades, etc.) but figured it's just a grift to get you to spend more dough. Looks like this time it may have come back to bite them in the ass with early loss … [Read more...]
