Fresh hacks every day
[Udo] decided to build a clock using the DCF77 radio module seen above. This of course has been done before: the hardware draws a clock signal from the atomic clock in Braunschweig, Germany. So he grabbed a library for Arduino and got to work. But he was getting rather poor results and upon further investigation realized that the library had … Read the rest
Here [Matthew Br] explains the situation he’s in with the neighbors that share this wall of his apartment. When they listen to music they like it loud and so he gets to ‘enjoy’ the experience as well. But he can’t ignore it any longer, and has decided to use a sound volume detector to blast some tunes right back at … Read the rest
[Karl] set out to improve the depth image that the Kinect camera is able to feed into a computer. He’s come up with a pre-processing package which smooths the depth data in real-time.
There are a few problems here, one is that the Kinect has a fairly low resolution, it is also depth limited to a range of about … Read the rest
As with many of the projects covered on hackaday, [bongodrummer]‘s Dust Sniper came about because of a lack of effective commercial solutions, in this case to the problem of quiet dust extraction.
Workshops are generally full of dust and noise, both of which take their toll on the human body. This is why safety regulations exist for noisy and dusty … Read the rest
[Christian] was running a Linux box as a home server but needed a way to quiet the noisy machine. Like many Linux servers, he’s using some pretty old hardware which doesn’t have an on-board header for the CPU fan which generates much of the unwanted sound. Those headers are nice because software can monitor the CPU and board temperature … Read the rest
Want to annoy fellow fans but don’t have the lung power to do the job? [Hunter's] electronic vuvuzela is just the thing you need. The plastic noisemakers were so prevalent at the world cup this year that some folks came up with audio filters to remove the sound. The electronic rendition is much smaller, using a 555 timer to mimic … Read the rest
[denha] has assembled a noise box he calls the XR-NOISE using an XR-2206 multi-waveform function generator. The output has an impressive number of controllable settings, and uses a set of LEDs to indicate sound level and rate. The XR-NOISE uses 1/4″ jacks for both in and out, and can also be controlled by the tap-sensitive mic located on the … Read the rest
