Fresh hacks every day
This is the desktop binary clock which [Tim the Floating Wombat] recently finished building. He calls it the Obfuscating Chronoscope since it’s a bit more difficult to read than your traditional analog or digital timepieces. But the simple design looks neat and it’s a great way to learn about board layout and microcontroller code.
He started by solving a few … Read the rest
[Brad] was asked by his Sister to design a motion-based alarm that would help her catch her son sneaking out of the house at night. Obviously this didn’t need to be a long-term installation so he decided to throw something together that is only active at night and can be battery-powered. What he came up with is a light-sensitive motion … Read the rest
[Rajendra Bhatt] wrote in to share the latest in a series of PIC tutorials, which covers the microcontroller’s Sleep mode – a very useful tool for limiting current consumption in battery-powered applications.
He discusses how to put the PIC in sleep mode, as well as some common mistakes to watch out for, such as accidentally allowing I/O pins to sink … Read the rest
Battery life is often overlooked when building projects, especially for beginners. This tutorial takes you through the setup of power saving modes for the Arduino. Utilizing the watchdog and sleep functions, they put the chip into a hibernation mode between cycles. An optimum configuration could take your battery life from 4 days to about 3 years. For a lot … Read the rest
