Fresh hacks every day
[Kees] wanted a remote for an XBMC audio system. He had a classic T65 Dutch telephone in one of his project boxes and thought this phone with the addition of a Raspberry Pi he could have a functional media remote with classic lines and 70s styling.
Each of the digits on the phone were wired up to a small solderless … Read the rest
So you’ve got a project running on an x86 board and you’d like some GPIO pins. Whether you want to read a few buttons, light up a few LEDs, put an accelerometer in your computer or whatever, you’ve got a problem. Luckily there’s an easy way to get 24 GPIO pins on an x86 board using a PCI card for … Read the rest
Here’s a Raspberry Pi hack that adds web control using PHP and MySQL. As you can see in the image, it serves up a webpage (using the Apache2 server) which allows you to change the state of the GPIO pins. It’s not super-complicated, but it is nice to see a step-by-step guide for installing and configuring the package.… Read the rest
Here’s another offering when it comes to PIC programming from the Raspberry Pi. The design seeks to adapt the GPIO header so that it may be used for programming PIC microcontrollers, but this does involve a bit more than just physically connecting pins to the target chip. Most of the PIC family require a 12V programming level, and this … Read the rest
Like many of us, [Jon] began his journey through the magical world of microcontrollers with an Arduino. For a beginner, the Arduino is a wonderful tool, but [Jon] quickly found himself limited by the platform. There are too few pins on the Arduino, and and the platform doesn’t really lend itself to extremely complex projects. To this end, [Jon] designed … Read the rest
Much to the chagrin of hardware tinkerers, the Raspberry Pi doesn’t have analog inputs on its GPIO pins. Sure, you can blink a LED with just a few console commands, but reading sensors with a bone-stock Raspi requires a little additional hardware. [Brian Dorey] just released a board that allows for 8 analog inputs on the Raspberry Pi with a … Read the rest
[Zaion] grabbed an ATX power supply to source the 5V the Raspberry Pi needs to run. The common problem when it comes to RPi supplies is a shortfall in how much current a USB wall adapter can source. The ATX shouldn’t have this problem, but none-the-less he found that the USB ports were only reading about 5V. Strange. He grabbed … Read the rest
