Fresh hacks every day
[mike6789k] wanted to spice up his dorm room, so he built a cool music synchronized light show that struck us as being very well thought out. We have seen similar music-based visualizations before, but they tend to be pretty basic, relying on volume more than actual audio frequencies to trigger the lighting.
[mike6789k] didn’t want to build “just another” synchronized … Read the rest
[magnetovore] made himself an electronic cello. Instead of pulling a few cello samples off of an SD card, he did it the old school analog way. The finished build is really impressive and leaves us wondering why we haven’t seen anything like this before.
[magnetovore] uses a permanent magnet to play each ‘string’. A lot of details are in … Read the rest
For his A-level electronic course work, [Andrew] decided to build a digital sound recorder that doesn’t use a microcontroller.
[Andrew]‘s build captures audio from an on board microphone at 8000 samples/second. The audio is digitized into 8-bit sound data and sent to an SRAM. The recording and playback functions are controlled entirely by 4000-series logic chips. He admits the … Read the rest
We are saddened by the recent passing of [Bob Pease]. You may not be familiar with the man, but his work has touched your lives in more ways than you can count. As an electronics engineer who specialized in analog components he was responsible for hardware that made some of the electronics in your life possible, and designed components that … Read the rest
[Jeri] threw down the geeky fashion gauntlet by building this LED enhanced dress. She chose to assemble the project for her trip to BarBot 2011, and we can’t think of a more appropriate setting for such a garment. It uses a motion sensor to set off a delayed pattern of blue lights hidden underneath the fabric.The best part of … Read the rest
The image you see above is the result of a simple analog projection clock. It shows the time on the ceiling. We have one in our bedroom but it’s a red digital display which we don’t think is nearly as fun as this clever hack. Grab a cheap analog clock, a mirror, and a white LED and you can build … Read the rest
[Tyler] has been using Google Voice extensively for some time now, but he hasn’t quite found a microphone/speaker setup he is happy with. He tried a headset, but that just didn’t do it for him.
While browsing around at his local thrift store, he came across an old Model 500 rotary phone for just a few dollars and decided it … Read the rest
