We featured a cool GPS Puzzle Box earlier this year that Markus built. It was based on a version that Mikal Hart created. Turns out there is quite a bit of interest in these GPS Puzzle Boxes, Mikal has since written a Make article which will be published in the Fall 2010 edition of the magazine. He has also been contacted by newspapers, movie directors and TV shows wanting to
Dig that GameBoy Advanced out of your closet for this GameBoy and PIC Microcontroller Hacked into an Analog Meter project. Ken Kaarvik used a PIC24HJ128GP502 to run the project, what is really cool is that the GBA doesn’t load the program from a cartridge but rather directly from the PIC microcontroller! This isn’t the first project that Ken has done with a Game Boy, have a look at lots more
Kenneth Finnegan just completed a Bi-Color LED Clock project that is based on the TI MSP 430 Microcontroller. Thanks to the cheap development environment I think we will soon see many more MSP430 projects in the near future. Kenneth used a plastic single gang junction box and a cover plate as the project box, coming in at around $1.00 it would be hard to find a cheaper box to house
Just stick the barrel of the gun in your ear and pull the trigger. That is how you answer this Bluetooth headset. Not sure you could use this in many places though. We recently had a law pass where I live that made talking on a cell phone and driving illegal. It is legal to use a bluetooth device to talk though. I am thinking that this device would still
Why do we have all of these redundant LED segments in the clocks around us. Just to show one digit of time we use 7 LEDs. If you are looking for a less is more solution to showing the time then you need to have a look at the Blinky Clock that John Boxall created. It is being run from a ATmega328 Microcontroller and a DS1307 Real Time Clock. This
Frank Pirz documented the build of his CNC machine which is based these plans. It was interesting to see that the 80/20 Aluminum was cut using a simple miter saw. The electronics case is a old computer case which is exactly what I also did, purchasing a large electrical box is quite expensive and computer cases are plentiful. Unlike most things, the older the case the better since older cases
Colin Karpfinger who brought us the Eagle PCB Design Ordering Tips last time is here with some more PCB help. This time Colin is helping us design a PCB Trace Antenna. One of these days you are going to make a product or project that needs to communicate without stringing a bunch of copper. To me antenna design is magic, some squiggles on a board talk to some squiggles on
