Fresh hacks every day
[Thibault Brevet] wanted his own party lighting that pulsed and faded along with the tunes. He ended up building a system based on an Arduino and a PC running Processing. The output from a mixing board is fed into a PC and measured by the Processing script. From there, the calculated light levels are sent to the Arduino to address the LEDs via the control board seen above. [Thibault] built four … [Read more...]
Here's a field-programmable RFID spoofer developed by [Doug Jackson]. He was inspired by the spoofers we looked at near the end of September that didn't have source code available. With the idea seeded in his mind he figured he could develop his own version, and then decided to share the build details with the rest of us. The tags that he purchased for testing and developing the spoofer have a … [Read more...]
The Clock Clock This digital display is made from several analog clocks with thick hands. Together they make something of a 7-segment display, which can be used to display the time. It reminds us of the "Shared Time" installation we covered previously. [Thanks Drum365 via Anonimiss Files] Quickly desolder lots of parts [Rhys Goodwin] is grabbing parts from junk PCBs but he's not … [Read more...]
Some parents buy kinetic sculptures for their kids at art or craft fairs. Not [Steve Moseley], he turned his kids' hovel into a sculpture by wrapping a marble run around the entire room. It's big enough, with so many features that finding a banner image was a bit tough. After the break we've embedded a video where you'll see a wagon wheel lifter, plenty of gravity-fed curves, loops, inclines, … [Read more...]
The robot above can balance an inverted pendulum. But wait, it gets better. It can balance an inverted pendulum that is articulated in the middle like the one seen above. Wait, wait, wait... it gets even better. It can start with the pendulum hanging below the sliding carriage, flick back and forth to get the two segments swinging, and then come to equilibrium with the pendulum as seen above. Once … [Read more...]
[Scott Harden] came across a few posts about QR code matrix barcodes coming through on the 40m baud radio band. A few operators had captured the signals and assembled them into the code block seen above but they weren't able to get a clear enough shot for a smartphone to decode the image. [Scott] took on the challenge and decoded the mysterious message himself. He tried some graphic editing to … [Read more...]
[Fileark] has been busy with the hacks lately. This time around he's built a solar-powered chicken coop door that opens in the morning, and closes at night. A single motor slides the door open and closed using a loop of spring-loaded string. There are limiting switches on either side of the door jamb to ensure proper positioning. The grey box seen above houses the hardware; a regulator for the … [Read more...]
