Fresh hacks every day
[Vinod Stanur] just finished another hobby project by building a WAV audio player using a microcontroller. He had started development a while back using a PIC microcontroller. But the chip he was using didn't have enough SRAM to allocate as a playback buffer. When he got his hands on an ATmega32 his mind turned back to the project and he saw it through to the end. He takes advantage of what he … [Read more...]
We think [FlorianH] did a bang-up job of prototyping his Minima Quadcopter on the cheap. The total bill comes in right around $200 and we're very happy with the quality of parts as well as the results. Here you can see the top of the double-sided board which he etched to host all of the components. At each corner there is a power MOSFET which drives the motor. At first glance we thought that … [Read more...]
Check out this setup that [Ruenahcmohr] is using in his air muscle experiments. The orange mesh contains an air bladder that is connected to a hose on the right side. The bladder can be filled, or emptied with two solenoid valves not seen here (but you can get a good look in the video after the break). The muscle attached to chain on the other end and is kept under constant tension by a spring. … [Read more...]
[SunWind] developed his own version of the Phillips Ambilight system (translated) which he is calling LiveLight. We've seen more than a few of these hacks, many of them are based around Arduino, and most use LED strip lighting. [SunWind] is using strip lighting as well, but his design is clean and polished quite a bit more than anything else we've seen. In our minds this would be welcomed by even … [Read more...]
[Oneironaut] is trying out a new GPS module with the prototype seen above. It's a San Jose Navigation device identified as FV-M8 and sold by Sparkfun for just under a hundred bucks. That's it hanging off the bottom-right of the breadboard seen above. They've packed a lot of power into the small footprint, and made it very easy to control at the same time. Although the device is fully configurable, … [Read more...]
With more pixels and more objects to track you're going to need to get that AVR running pretty fast to get the job done. But [Vladutz2000] figured why stop at 16 MHz when you can overclock an ATmega32 to 27 MHz for a faster gaming experience? This build may not be as colorful as Super Pixel Bros, but choosing a KS0108 graphic LCD certainly brings a lot more definition to the images. You can see … [Read more...]
This is a bench power supply with adjustable voltage and current limiting. [Sylvain's] creation can regulate 0-25 volts while sourcing 0-5 amps. Current limiting is a nice feature as it will allow you to test your prototypes to ensure the power regulator you choose will not be over or underpowered. This supply is really a two-in-one. The case has two separate circuits so that you can have … [Read more...]
