Fresh hacks every day
We've seen composite video out from AVR chips many times before. But we can't remember coming across one that managed to produce a color signal. This project does just that, producing a color video signal from an ATmega168 without using external integrated circuits. [CNLohr] is seen here showing off his accomplishment. You'll remember him from the glass-slide PCB server project he's been … [Read more...]
This rig is something of a museum or art installation, but the concept is so simple we thought it could easily inspire your next project. The two mirrors and two video sources make up a stereoscopic display. The user sits between two displays (computer monitors shown here, but the post also shows images projected on two walls of a room). A pair of mirrors mounted at forty-five degrees form the … [Read more...]
[Steve] really has a nice microscope setup in his lab now that he built a video camera adapter for his stereo microscope. The image above shows the magnified view of the circuit board on the LCD screen behind it. This lets him work without needing to be in position to look through the eye pieces. The hack is a perfect complement to the custom stand he fabricated for the scope. The camera … [Read more...]
We get a ton of tips about weather balloon launches taking hobby electronics into space. But every once in a while one of them stands out from the rest. This project does send an electronic payload into space, but it also lets [David] fly his hardware back from near-space using an RC airplane. The return vehicle is unpowered, but that shouldn't be a problem as launching from a weather balloon … [Read more...]
Touch screens are nice -- we still can't live without a keyboard but they suffice when on the go. But it is becoming obvious that the end goal with user interface techniques is to completely remove the need to touch a piece of hardware in order to interact with it. One avenue for this goal is the use of voice commands via software like Siri, but another is the use of 3D processing hardware like … [Read more...]
[Hamster] admits this 1080p HDMI hack for an FPGA doesn't put a signal that's fully up to specifications. But as you can see in the image above it does output a 1920x1080 image at 60 Hz, which is the size and frequency of full HD video. It falls just short due to some jitter, which may be just fine if this is only being used for early prototyping and will be replaced with a dedicated encoder later … [Read more...]
This thing is so cool it almost looks fake. But [Matt Richardson] isn't a hoaxster. He actually built what might be called a heads-down display for your bicycle. He refers to it as a headlight because it borrows a similar function. It mounts on the handlebars and shoots light off the front of the bike. But it's more than just a battery and a bulb, this uses a pico-projector to give that light some … [Read more...]
