Fresh hacks every day
With the coming of Android 3.1 you finally have the option of using the device as a USB host. This may be through a USB OTG (On-the-Go) adaptor, but nonetheless it’s a feature which was sorely missed until now. [Manuel] put together a guide on using Android as a USB host. As you can see, his example hardware is … Read the rest
So let’s say your using an Arduino in your project. You already have the hardware-based serial interface working with one portion of the project and need a second serial port for unrelated hardware. The obvious solution is to write one in software. But this is a place where working in the Arduino environment gets really hairy. Since there’s a layer … Read the rest
Around this time last year, [KopfKopfKopfAffe] was enlisted as a set designer and was told to build some sort of light effects for electronic music parties. The budget for the project wasn’t much at 200 Euros, but he did manage to build decent 5×5 RGB LED matrix that is fully controllable by a computer.
[KopfKopfKopfAffe] didn’t have the time or … Read the rest
X10 has been around for a long time. It’s the brand name for a set of wireless modules used to switch electrical devices in the home. There’s all kinds of different units (bulb sockets, electrical outlets and plug pass-throughs, etc.) and they’re mass-produced which makes them really inexpensive. Whether you already have some X10 controlled devices or just plan to … Read the rest
[Andrew] is trying to buckle down and hammer out his PhD project but was surprised by the sorry state of the configuration options for his FPGA/ARM dev board. Using JTAG was painfully slow, so he studied the datasheet to see if there was another way. It turns out the Xilinx FPGA he’s using does have a slave serial mode so … Read the rest
[Larsim] worked out the timing necessary to read button and joystick data from an N64 controller using an ATtiny85 microcontroller. The project was spawned when he found this pair of controllers in the dumpster. We often intercept great stuff bound for the landfill, especially on Hippie Christmas when all the student switch apartments at the same time.
Instead of cracking … Read the rest
If you find a crusty old IT guy and give him half a chance, he’ll probably regale you with stories of how things were done “in the old days” where no one had their own computer and everyone worked on mainframe-connected dumb terminals. [JSTN] yearned for a true to life terminal display that he could attach to his 2010 Mac … Read the rest
