Fresh hacks every day
There are Kinect hacks out there for robot vision, 3D scanners, and even pseudo-LIDAR setups. Until now, one limiting factor to these builds is the requirement for a full-blown computer on the device to deal with the depth maps and do all the necessary processing and computation. This doesn't seem like much of a problem since [wizgrav] published Intrael, an HTTP interface for the … [Read more...]
The quest for a project box is always a balance between cost, complexity, and style. We think [Pcmofo] really finds the mark with his exterior electrical box enclosures. He took the time to document his fabrication process for those that want to replicate his look. These grey plastic boxes are meant to keep the elements away from home and commercial electrical systems. They're easy to find and … [Read more...]
The echo box performs exactly as its name implies. If you tap out a rhythm on the lid, it will tap the same thing back to you. Except it isn't tapping to make the sound, but vibrating. The concept is similar to the Knock Block. In that hack, a piezo element detected a rapping on the wooden enclosure and repeated the rhythm by striking the lid with a solenoid. This iteration also uses a piezo … [Read more...]
[Afroman's] latest video shows you how to add reverse voltage protection with minimal power loss. At some point, one of your electronic concoctions will turn out to be very useful. You want to make sure that a battery plugged in the wrong way, or a polarity mistake with your bench PSU doesn't damage that hardware. It's easy enough to plop in a diode for protection, but as [Afroman] points out, … [Read more...]
Looks like [Dino] is getting the band back together. After a junkyard tube amp and a DIY tremolo stompbox, he's back again, this time doing a bit of sound treatment in his studio. Most rooms naturally have a bit of flutter echo. You'll notice this when you move into an apartment or new house - rooms sound a lot more cavernous without rugs, drapes and furniture. Unfortunately, having a bunch of … [Read more...]
Reading from a large number of inputs, like this piano keyboard, can be tedious. Even when multiplexing there's a lot to keep track of. But if you choose the right microcontroller, you may have hardware assistance. Here's an ATmega640 is using it's external memory interface to read the key matrix. You may remember the Open Music Labs article about reading from a shift register using just one … [Read more...]
If you are considering repurposing some old computer equipment to create music, be aware that the bar has been raised just a tad. YouTube user [BD594] spent some time sifting through his bin of used electronics and put together a 5-piece band that plays a pretty awesome rendition of The Animals’ “House of the Rising Sun”. Last week, we saw a pretty impressive hack with a floppy drive that … [Read more...]
