[The Cheap Vegetable Gardener] assembled his first grow controller about three and a half years ago. He's been very happy with it and knows that he'll be using it for years, maybe even decades to come. He just finished overhauling the grow controller design to help make sure he doesn't burn down his garage one day. You have to admit, without knowing anything about the project this rendition does … [Read more...]
The Arduino has gone from an interesting concept to one of the most common tools for a budding hacker. We've covered everything from the origin of the Arduino to plans to build your own arduino. Modifying arduinos is also a common occurrence. Arduino sketches have become an expected inclusion in documentation much to the annoyance of those who had to do everything from scratch before its existence.
We have tutorials on how to do all kinds of things with an arduino, like making a lock for your door, or automating systems. We’ve seen practical arduino projects as well as jokes involving arduinos in some way.
How many times can you put two LEGO pieces together and take them apart again before they wear out? The answer is 37,112. At least that's the number established by one test case. [Phillipe Cantin] was interested in this peculiar question so he built the test rig above to measure a LEGO's lifespan. The hacked together apparatus is pretty ingenious. It uses two servo motors for testing, each … [Read more...]
[Hans Peter] wanted to move away from using full Arduino boards in his projects. One of the components he rarely used after the development stage is the USB hardware. Once the firmware is flashed to the chip he didn't need it any longer. So he tried his hand with some really small SMD parts by building this USB to serial Arduino programmer. The chip he went with isn't the FTDI part we're used … [Read more...]
[Nick] and [Simon] both have home security systems with a monitoring service who will call whenever an alarm is tripped. For [Simon] this ends up happening a lot and he wanted to change the circumstances that would trigger a call. Because of company policy the service is inflexible, so he and [Nick] went to work cutting them out of the loop. What they came up with is this custom electronics board … [Read more...]
Whether you like it or not, every second that passes brings you one step closer to your own demise. It's not a comforting topic to dwell upon, but it's reality. This art installation entitled 'Memento Mori' is a haunting reminder of just that. Even with all the advanced technology we have today, we still have absolutely no way of knowing just when our time will come. [Martin] cast a real human … [Read more...]
Have a significant other that isn't the best at picking up the phone? [Aaron] was having a hard time reaching his wife, so he hacked up a solution. The Moshi Moshi detects calls from [Aaron], and plays music to get her attention. A remote server running Asterisk picks up the call and uses a Ruby script to log the call. Every ten seconds, an Arduino Due with an Ethernet shield polls a Sinatra … [Read more...]
We're all about big machines that build things for us - laser cutters, CNC mills, and 3D printers are the machines de rigueur for Hackaday. Too often we overlook the softer sides of fabrication that include textiles and knitting. [varvara] and [mar] are doing their best to bring us the softer side of things with their modification of a Brother knitting machine. They call their build Knitic, and … [Read more...]
