Fresh hacks every day
Here's another Flora Arduino based project from [Becky Stern]. It's a backpack with brake lights and turn signals for use when motorcycling, but it should work just as well for bicyclists. From this view the project looks pretty normal, but things get downright crazy when she decided to use the WS2801 pixels for the LEDs. Sure they take all the work out of driving an array of LEDs, and they offer … [Read more...]
[Michael] posted up-to-date GPS data sets in the GPX format. These data sets are an alternative to paid updates. Since GPX is a published standard which uses an XML style formatting for location data [Michael's] time was spent getting the original sets and finding a way to translate them for his Garmin EXTREX GPS. The original data comes from -- hang on, this is a mouthful -- the US Federal … [Read more...]
Plug in the power and Ethernet and this Raspberry Pi board will automatically collect Windows hashes from computers on the network. With a couple of RPi boards on hand [Travis] was searching for more hacks to try with them. This made a great little test to see how the board performs with the well established attack. To start he booted into the standard Raspbian distribution. From there he loads … [Read more...]
[D S] wanted his own head-mounted display. What you see here is just his mockup, but somewhere along the way he realized it's closer to a finished build than just being a stating point. Not only does it work well for gaming, it came in at under $200 all in. You think your girlfriend makes fun of you now for wearing that big microphone headset while playing? Just wait until she gets a load of … [Read more...]
The LVL1 Hackerspace held a hackathon back in June and this is one of the projects that was created in that 24-hour period. It's a 3D scanner made from leftover parts. The image gives you an idea of the math used in the image processing. It shows the angular relations between the laser diode, the subject being scanned, and the webcam doing the scanning. The webcam is of rather low quality and … [Read more...]
Imagine a single chip able to interface with your Ethernet, USB, and serial devices, turn those connections into wireless radio signals with miles of range, able operate off a single AA battery, and costs less than $2. That's the promise of the Weightless special interest group that wants to put several hopefully not vaporware radio chips in the hands of everyone on the planet. Long-range … [Read more...]
Senseo coffee makers are automated brewers that use coffee pods. [Ronald] had one, but wasn't satisfied with the quality of the coffee it produced. His solution was to hack it apart and build his own automatic coffee machine with the innards. The coffee brewing part of the system is controlled by an ATmega8. This reads the temperature using the NTC sensor from the original machine and actuates … [Read more...]
