Fresh hacks every day
If you don't mind ending up with oddly shaped 3D printed parts you can get your printer to sing to you. The exhibit shown above is doing just that. The Lulzbot is being driven specifically to produce a certain frequency of sound with its stepper motors. The results of a few different songs are what's hanging on the wall to the right. You can hear it printing Bizet's Carmen in the clip after the … [Read more...]
What's your favorite color? Don't tell us, Tweet it to [Sebastian's] favorite color Twitter display and you'll be contributing to the artwork hanging on his wall. This answers a very important question, what do you do with your projects after they're completed? For us the best part is the planning and building. Once it's done the thrill is pretty much gone for us. We haven't even switched on … [Read more...]
[Matthias Blaicher] may think this isn't a big deal when it comes to the amount of work he put into the hack. But for us, anything that extends the functionality of the versatile yet affordable Rigol DS1052E is a win. In this case he's taken a previous hack and made it work for more people by extending the functionality of the WFM file format viewer. [Dexter2048] pulled off the original hack … [Read more...]
We're sure you've heard by now that Google has decided to close its RSS feed aggregator service called Google Reader. We've got to remember to get our list of thousands of great hacking blog feeds off of there before it's gone. But just preserving the list is rather easy. [Paul Kerchen] has a bit different problem. He's got hundreds of articles starred and he wants to preserve a way to find those … [Read more...]
[Brian] has brought together a powerful collection of hardware to build a robot. The end goal is to have a robot that's controlled by a Wiimote. The Wiimote communicates over Bluetooth with a Raspberry Pi, which is running a Python script. This script uses the CWiid Python module to communicate with the controller, and [Brian] has detailed instructions on getting the Wiimote working with a … [Read more...]
[Dave] wanted to show off a project at his 4th-grade son's school during their family science night. We haven't heard of an event like this before but it sounds like a fabulous idea! He had a new laser he wanted to include in the project, and noticed that his son was learning about how ASCII maps letters to binary number when the idea struck. He ended up building an optical data transfer system … [Read more...]
[Navin] has been hard at work producing a GUI which works with different micocontrollers. The idea is to make it even easier to develop projects by simplifying the feedback and control you can get from the prototyping hardware. The best part about it is that he designed the software to interface with any hardware which can be programmed in C++. The screenshot above shows the program … [Read more...]
