Casio EX-FH20 Budget Super Slow-Mo Camera Lightning Review

Benny Goldman — Wed, 19 Nov 2008 17:00:00 EST

The Gadget: The Casio EX-FH20 camera, bargain brother to the popular EX-F1. It features 1000 fps slow-mo video, a 40 fps burst mode for still shooting and a 9.1-megapixel sensor, as well as good ol' 720p at regular speeds, all for just over half the price of the original slow-mo star. The Price: $600 The Verdict: Casio did a great job of bringing the power of the EX-F1 down to a beginner's level for the EX-FH20. The functions on the new camera are more streamlined than its bulkier predecessor: missing are the dedicated shooting mode switch dial, the multi-use focus/zoom ring and separate buttons for video and still capture from the F1. But on the other hand, the FH20 bests the F1 in a couple places, with its 9.1MP sensor and 20X optical zoom, compared to 6MP and 12X in the original. The on-board video editor is still there and simple to use for cutting down lengthy slow-mo clips. And whaddya know, it takes decent (albeit more point-and-shoot than DSLR quality) pictures too, as seen in the gallery below. But we know what you really want to see: how the slow motion video compares to the original exploding Mentos-capturing beast. As seen in the clip above, it does the job much like the original. You give up some video frames when opting for the budget cam—it records 210, 420 and 1000 fps instead of 300, 600 and 1200 fps—but that's not a huge difference. And while 1000 fps video shrinks is at a paltry resolution of 224x56 pixels—even measlier than the original—it doesn't get as dark as the F1's output tended to, so you'll have slightly more clarity in the crazy slow but still mostly novelty setting. It also shoots other types of video well. The 30 fps-210 fps "She Walked in the Room" mode is still there, and is a fun way to make otherwise typical activities look extremely epic. Also, 720p HD video is crisp and clean, and doesn't have the nasty "jello effect" when panning that cheaper camcorders designed specifically for this purpose often suffer from. If you choose an FH20 over the F1, you sacrifice more than just not-as-slow-mo video. Without separate buttons for video and stills, you lose the ability to capture images while you record video, a great feature in the last model and the hardest thing to lose. Also gone is ultra-fast 60 fps LED strobe flash option, but it can still fire off 5 fps with the standard flash firing (vs. the F1's 7 fps). Most of the other features remain, though slightly dialed down: 40fps high-speed burst shooting (with resolution dropped to 7MP) instead of 60fps on the F1, and smaller sizes for slow-mo video as mentioned earlier. And you better bring some rechargeable batteries—gone is the rechargeable Li-ion, and this camera eats four AAs like they were a delicious piece of cake. But with the steep discount over the F1 and the more direct, easier to use interface, for those who mostly want to shoot slow-mo video while taking a few pictures on the side it's not a hard sacrifice to make. [Casio] What you gain with the EX-FH20 over the EX-F1: • 9.1MP camera sensor over 6MP • 20X optical zoom over 12X • Easier interface for beginners • $400 in your pocket (vs. the EX-F1's $1000 price tag) What you lose: • Slow-motion video size and frames (EX-FH20 records in 210, 420 and 1000fps at 480×360 224×168 and 224×56 respectively—EX-F1 records in 300, 600 and 1200fps) • Taking still shots while shooting HD video • 60fps LED flash strobe mode • 20 fps of burst still shooting (down to 40 fps compared to 60 before) Once again, if you can't get Giz's slow-mo song du jour out of your head, here's the Amazon MP3 link.

Massive Lego Mecha Can Probably Kill Humans, then Drink Ten Packs of Good Ole Fortran

Jesus Diaz — Thu, 04 Sep 2008 08:00:00 EDT

This is what you get when you combine Lego and massive mechas done at the minifig scale: the biggest robotic overlord I've laid my eyes on. Then, when you go through the massive gallery, you get what I call a robner followed by a brickgasm. Updated: actually, reader/brother Oscar sends me pictures of a huge ~~Bionicle~~ Exoforce mecha he saw last weekend, which looks even bigger.

The gigantic model won the Best Mecha award at last weekend BrickFair. And talking about minifigs, did I mention we have a video contest going? Yeah, that's what I thought. Carry on.

However, the first one looks a lot bigger and definitely better. [Flickr via Brothers Brick]

Lego Robot Sends Pictures from Space, Wishes It Had Lasers to Annihilate Us All

Jesus Diaz — Fri, 01 Aug 2008 14:59:00 EDT

Last Tuesday, a group of professors, students and robotics hobbyists launched the H.A.L.E. (High Altitude Lego Extravaganza): seven Lego Mindstorms robots attached to a weather balloon, which exploded at 30km over the Earth's surface. Each of the robots parachuted back successfully, but not without taking the obligatory photographs of the ascent and descent:

The seven robots were designed to achieve seven different missions:

Brian Davis, Indiana, USA
Project: Little Joe
This robot will perform an automated free-fall in an attempt to set the record for the longest MINDSTORMS NXT free-fall. The robot will be detached from the main balloon near maximum altitude and will free-fall until the parachute deploys.

Project: Gypsy
The robot will be an automated camera platform that will take both video and still images. The MINDSTORMS NXT will control all image timing as well as pitch angle

FLL Team 90/David Levy (Coach), Virginia USA
Project: FLL Team Challenge: Climate Connections
A FIRST LEGO League Climate Connections team will build a robot to measure UV radiation as a function of altitude. The MINDSTORMS NXT will not only data log the UV sensor readings, but will also be used to rotate the UV filters in position as well as control the robot heater with a temperature sensor.

Barbara Bratzel & Chris Rogers, Tufts University, Massachusetts, USA
Project: Fourth Graders
A group of 4th grade students will investigate the impact of flight conditions on yellow marshmallows (a.k.a peeps). The MINDSTORMS NXT will be recording temperature and pressure during the mission.

David Martinez, Jurgen Leitner, Sweden
Project: SpaceMasters
The robot will be measuring the change in G-forces as a function of altitude. The robot will repeatedly drop a tethered Wiimote at different altitudes to measure the acceleration experience.

Claude Baumann, Francis Massen, Jean Mootz, Luxembourg
Project : LUXPAK
The robot will be using an RCX to measure ozone concentration, air pressure, temperature (inside and outside) and reflected light from Earth during the descent.

Eugene Tsai, Taiwan
The robot will be using filtering papers to capture particles and/or chemicals in the air during the balloon ascent and descent periods. The LEGO Mindstorms NXT will be used to provide a mechanism to switch filtering papers to capture the materials in the air and then keep the papers in a secured compartment. The filtering papers will be retrieved and analyzed to see what chemicals and particles exist in different altitudes.

Honeycomb Skyscraper Has No Internal Structure, Attracts Giant Killer Wasps

Jesus Diaz — Fri, 01 Aug 2008 05:39:47 EDT

Design goodness hunters Dezeen got this pictures of the 1,174-feet-high Sinosteel International Plaza in Tianjin, China, designed by architects MAD—or just mad architects. The external white honeycomb structure, with huge hexagonal windows that vary slightly in size, is not just for the pretty looks: it will sustain the whole building without the need for any internal structure. And make it look like a huge wasp nest to me. From the inside, however, each room looks like a space station.

The variable size of the windows is not just to make the building more interesting. According to the architects, the pattern was created to adapt to the wind and sun:

By mapping the different air flows and solar direction across the site, we were able to position different sized windows accordingly, minimizing heat loss in the winter and heat gain in the summer.

The building—located in a port city one hour east of Beijing—will be finished in 2012, including the big office tower and the smaller one, which will be dedicated to a hotel. [Dezeen]
