Fresh hacks every day
This hardware, which was built as a Computer Engineering project by [Bryon] and his classmates, gives you feedback and control of a car though a cellular phone network. It uses text messages to communicate with a control device. This can be pretty much any cellphone, but in the clip after the break they show off an Android app which … Read the rest
This home automation hardware turns on and off the lights based on room occupancy. The hack is an extension of an earlier version that was only a proof of concept. [RPisces] took the idea and made it into reality by mounting the sensor hardware in a doorway.
He prototyped the device using the MSP430 launchpad. It monitors a pair … Read the rest
Meet the Art Controller, a new dev board available over at Evil Mad Scientist Laboratories. It provides a drop-in solution for switching higher voltage loads (but not mains). The thing we like most about it is the ability to alter a switching delay without reprogramming the firmware.
The board uses an ATtiny2313 for control. It’s fed regulated 5V power … Read the rest
This work clock functions in an unexpected way. With each passing second it displays a random four letter word on the right side of the display. Traditional word clocks tell the time in natural language, but this one is simply used as a learning opportunity.
[Iron Jungle] got his hands on the display for just five buck from … Read the rest
[Mansour] had a ceramic space heater mounted near the ceiling of his room. Since heat rises this is not the best design. He upgraded to an infrared heater which works a lot better, but lacks the timer function he used on the old unit. His solution wasn’t just to add a timer. He ended up building a Bluetooth module into … Read the rest
[Alex] was tasked with a control design problem for a set of motors. The application called for the back of a truck to open up, some 3D scanning equipment to rise from its enclosure, and finally the equipment needed to rotate into place. All of this needed to happen with one flip of a switch, then proceed in reverse when … Read the rest
So [RobB] wanted to take out all the light switches in his house. His plan was to replace them with a system that could be operated from his smart phone. But his wife insisted that there still must be some way to control the lighting directly — we have to agree with her on that one. The solution was to … Read the rest
