Fresh hacks every day
How much memory do you really need? We suppose it's not really our place to judge how you misuse use memory in your projects. But we do appreciate the clean and orderly technique that [Eric Rogers] uses to add multiple SPI SRAM chips to an Arduino. The heavy lifting is done with a CPLD shield called the Amani 64. It intercepts the SPI calls from the Arduino to an SRAM chip, and translates the … [Read more...]
A few months ago [Jason] got his hands on a free Coby DP700WD digital picture frame and thought it would be fun to hack. After realizing that the frame did not run any sort of Linux-based OS he figured his options were pretty limited, but he gave it a shot anyways. The frame came with a set of built in images, and his goal was to swap them out for pictures of his own. He started by trying to … [Read more...]
[Mirko] is working on a library that will allow you to add RF control to just about any device. The only requirement is that the device be capable of running a Linux kernel, and that it have a few GPIO pins available. One example is fairly straight forward, a Netgear router. Many, if not most routers run a Linux kernel natively and most have solder points on the board for unused IO pins so … [Read more...]
[JB's] driving a Nokia 6100 LCD using an MSP430 with input from a Wii Nunchuck. He's using the G2211 microprocessor that came with the Launchpad, and developing his code with MSP-GCC. As you can see in the video after the break, this works but there's some room for improvement. That's being said, he is bumping up against the code memory limit, with just around 500 bytes left to work with. The LCD … [Read more...]
It's fun to pick apart code, but it gets more difficult when you're talking about binaries. [Joby Taffey] opened up the secrets to one of [Travis Goodspeed's] hacks by disassembling and sniffing the data from a Zombie Gotcha game binary. We looked in on [Travis'] work yesterday at creating a game using sprites on the IM-ME. He challenged readers to extract the 1-bit sprites from an iHex … [Read more...]
[Rossum's] taking a look at the Nokia LCD screens that are both plentiful and begging to be bent to your will. For quite some time the Nokia 6100 screens have been used in a lot hacks, but he wanted to see what else is out there. He digs into his junk box of cell phones and comes up with a couple to test; the Nokia 6101 and Nokia 2760. The screens use a 3-wire SPI interface, which he sniffs out … [Read more...]
Our initial view of the Spy Video TRAKR “App BUILDR” site had us believing this would be an internet-based code editor and compiler, similar to the mbed microcontroller development tools. Delving deeper into the available resources, we’re not entirely sure that’s an accurate assessment — TRAKR may well permit or even require offline development after all. Regardless of the final plan, … [Read more...]
