Fresh hacks every day
[Stephen] picked up a Raspberry Pi to do a little hardware hacking and add a blinking LED to the many feathers in his software development hat. He picked up an analog to digital converter and a temperature sensor that would serve him well in a few projects he wanted to put together, including a weather station and a small Pi-controlled … Read the rest
If you’ve picked up one of those really cool STM32 ARM dev boards, you’ve probably poked around looking for a good toolchain. No fear, then, because [Matt] has your back. He put together a template for the ARM Cortex-M4 powered STM32 board.
[Matt] had been using a template for the STM32 F4 we’d covered before, but found the implementation … Read the rest
Don’t want to learn about evolutionary algorithms the usual way, by generating sentences from random letters, or randomly placing pixels to generate the Mona Lisa? Then make your own evolutionary algorithm! With blackjack!
[Brian] has been playing around with evolutionary algorithms, and wanted a task that’s well suited for optimization. He chose blackjack, because of the limited number of hands … Read the rest
The folks at the London-based startup GoCardless have a pool table at their office. Being the techies they are, they decided to build a system that automatically scores games. The results, while not fully complete, are still pretty impressive for something whipped up during a 48 hour hackathon.
The automated score keeper uses a webcam duct taped to the ceiling … Read the rest
The Arduino IDE is extremely similar to C++, but judging from the sketches you can find on the Internet, you’d never know it. Simpler Arduino projects can make do with just toggling IO pins, reading values, and sending serial data between two points. More complex builds fall into the category of real software development, and this is where the standard … Read the rest
It looks as though Texas Instruments are really reaching out to the hacker community with their new ARM-powered Stellaris dev board. On the Stellarisiti forums, a member asked about the debugging options for the Stellaris board. The Stellaris already features an In-Circuit Debug Interface (ICDI), but unfortunately it’s a little hard to get working in Linux-ey environments.
One of the … Read the rest
[Dimitri] sent in a project he’s been working on that implements a Java Virtual Machine purely in C, and is easily portable between microcontrollers such as the AVRs and PICs we normally see, ARM devices, and even the lowly 386.
Before going into the ‘how’, [Dimitri] first covers why he wanted to run Java bytecode on a microcontroller. Basically, … Read the rest
