Wide Angle Lense Mod For The ATC2K

For those that have them, the ATC2K action camera is a decent little piece of equipment. It is waterproof and can save video for roughly 30 minutes on a flash card. The viewing angle of the lens leaves something to be desired though. This has been remedied in newer models. [raalst] shows us how to modify the ATC2K to install a new, wider angle lens, while retaining the waterproof seal. He also takes us through a necessary mod to ensure clear video under water since the new lens was not initially intended for it. Just in case you are curious, he’s using his for hobby radio controlled submarine dives.

LED Bottle Wall

Here are two new projects from [Alex Beim] at Tangible Interactions. The video above is the bottle wall with a controllable LED behind each bottle. Embedded below is the 7×5 pixel Rainbow Box. He’s planning on writing a Quartz Composer patch to actively drive the display.

Peggy 2 Super Pixels

[Windell] from Evil Mad Scientist Laboratories took one of their Peggy 2 kits and gave it a little upgrade. The Peggy 2 is a programmable 25×25 LED display. It’s Arduino compatible and can accommodate big 10mm LEDs. Most people assemble them using just one color, but [Windell] decided to create giant RGB pixels by placing discrete red, green, blue, and white LEDs next to each other in the board. This creates a 12.5×12.5 grid of full color pixels. It’s an interesting effect and you should definitely check out the video embedded below which shows how the transition can be smoothed using a diffuser. Continue reading “Peggy 2 Super Pixels” →

SPDIF Switch

switch

When [linux-works] found himself needing a switch that could convert coax to opto, he made one. The main chip is a cd4052 cmos analog switch, which he says is really cheap. The rest is pretty self explanatory. This setup can switch between 4 different inputs as well as do the coax to opto conversion.

Space Invader Button

[Marcus] saw [Alex]’s 64 pixel project and decided it could be implemented in even less space. Pictured above is his Space Invader button with a bicolor LED matrix. The controller board is all SMD and piggybacked on the matrix. An ATmega164P drives the 24 pins via transistors. In addition to animation, the board can do LED sensing too. It’s a very clever project and [Marcus] has some notes about working with such tiny components. You can see a video of it below. Continue reading “Space Invader Button” →

POV Pong

[Akeeh] posted something to our flickr pool that caught our eye. The image was a rotating POV display, playing pong. We followed through the links and found this very well done rotating pov display. The construction is quite nice, showing multiple colors and smooth motion. there’s a little bit of wiggle even though it has a custom round pcb. Maybe a little better counter weight would help with that. The idea isn’t new, but it is good looking and elegantly made.

Arduino VGA Glitching

glitch

For some people, mistakes or glitches has become an art form. We’ve seen it in circuit bending for a while, but the newest version is in video glitching. [Sebastian] has gone so far as to intentionally set up an Arduino to send a glitched signal to a monitor. His description sounds pretty easy. We’re just assuming this is in motion in some way, a video of it in action would be nice.
