A simple panning motion can add impact to the already-dramatic effect of time lapse photography. To accomplish this, frugal cinematographers sometimes build [Rube Goldberg] contraptions from clock motors, VCR parts or telescope tracking mounts. Hack a Day reader [Stephan Martin] has assembled a clever bargain-basement system using an Arduino-driven stepper motor and a reduction gear system built up from LEGO Technic parts, along with some Processing code on a host PC to direct the show.
While the photography is a bit crude (using just a webcam), [Stephan’s] underlying motion control setup might interest budding filmmakers with [Ron Fricke] aspirations but Top Ramen budgets. What’s more, unlike rigid clock motor approaches, software control of the camera mount has the potential for some interesting non-linear, fluid movements.
Do you need to keep tabs on the kids while they browse the Internet? How about your husband/wife – do you suspect they are dabbling in extra-curriculars on the side? Hey, you’ve got your
insecurities reasons, we won’t judge. We will however, show you what [Jerry] over at Keelog has been working on lately.
While the company sells hardware keylogger kits online, [Jerry] has relied on, and understands the importance of open source. Since we all benefit from things being open, he is giving away all of the details for one of his most recent projects, a wireless keylogger. The keylogger plugs in to a PC’s PS/2 port, and wirelessly sends data to a nearby USB dongle up to 20 yards away, all in real-time.
A detailed parts list is provided, as are schematics, PCB masks, firmware, and assembly instructions. However, if you prefer the easier route, you can always buy the completed product or a DIY kit.
This isn’t the first open source keylogger he has released, so be sure to check out his previous work if you prefer a wired keylogging solution.
[nmcclana] has posted an assembly walkthrough for an Arduino-style prototyping board for the 80 MHz, eight core Parallax Propeller Microcontroller. While not board compatible with Arduino shields like the ARM-based Maple board we covered, it does have that familiar layout, and provides access to all 32 I/O pins, and the 3.8″ x 2.5″ footprint was kept in mind to allow easy creation of shields modules that can be designed using ExpressPCB’s miniboard service. The Platform Kit also has the advantage over other Propeller kits such as SchmartBoard’s offerings, which require soldering of surface mount parts. Kits are available at Gadget Gangster, and ready for your next design that needs a little more sauce than the Arduino can offer.
[Julien Bayle] has posted this great breakdown of building an RGB monome clone. He is a musical performer using Ableton Live. He wanted to do away with the need for a computer screen and found that the monome would have been perfect had it been RGB. So he decided to build his own.
The parts list for the entire project is as follows:
He also has files for the schematics and source code as well as information on how to assemble and test it.
The RGB aspect is still under development. He is using the LEDMatrix-Serial Interface-RGB from Sparkfun Electronics to run it. It is expensive, but is exactly what he was looking for.
There aren’t very many pictures of the project, and none of the working RGB unit. He makes up for it in sheer information. Many parts have links to manufacturers or support forums. Hopefully he’ll post some pictures and video of the final product soon.
A bench vice can be one of the most used tools in your workshop. For those that don’t have a workshop [Matt] built a vice that clamps to a table. He used scrap wood, MDF, threaded rod, washers, nuts, and wing nuts. Cheap, easy to build, and very useful!
