Fresh hacks every day
[Chris Suprock] is interested in using technology to improve your accuracy with a firearm. To that end, he’s using an Accelerometer mounted to a gun to gather feedback about each shot.
The hardware setup is pretty simple. We don’t have specific details, but it looks like he’s using a QFN accelerometer chip like you would find in a cellphone. The … Read the rest
The Sansa Clip+ is a nice little MP3 player and recorder. But it doesn’t offer an input connector, instead relying on the built-in microphone. [Simon Frank] wanted to extend its functionality so he figured out how to add a standard audio jack for analog input.
This is not the first time this has been done, but [Simon] has found … Read the rest
It’s no secret that we’re fans of open source, and open hardware. And we have to applaud companies like SparkFun who also keep their customers in the loop about what’s going on with the business end of the company. For instance, they were recently contacted by a Sheriff’s office and asked for customer information and are sharing the story. One … Read the rest
There’s something special about improvised weapons built for the upcoming zombie apocalypse. Whether it’s a Lousiville Decapitron or a shotgun revolver, we’re always fascinated by homemade weapons. Here’s a few that rolled into the tip line over the last few weeks:
[Joerg Sprave], a.k.a. that German guy on YouTube that has fun with slingshots, … Read the rest
[Kilian] sent in a link to a color version of a tiny educational computer. It’s called the Quantumite and it’s designed to be a throwback to the early 80s microcomputers we all grew up on.
The Quantumite is a clone of the Maximite, the tiny single board computer / BASIC interpreter designed by [Geoff Graham]. Both the Quantumite … Read the rest
We’ve seen a few minimalist robots in our time, but very few compare to [Thomas Rinsma]‘s amazingly agile BEAM robot. It’s absolutely fascinating to watch this little robot crawl around on its circular legs.
BEAM robots are extremely simple robots built without a microcontroller of any kind. The idea that extremely simple circuits built from logic chips and amplifiers … Read the rest
3d printing has come huge strides in ability to construct detailed objects. Unfortunately, color is still a considerable limitation. Here, some people at the Reprap blog are having fun coming up with an extruder head that actually mixes two colors as it deposits them. Don’t confuse this with the dual head that Makerbot is touting that allows you to … Read the rest
