Hackaday Links

Links

with temps in the 90s all week, we can only assume two things:
1. we will be having ungodly lazy afternoons
2. we’ll be grillin’ links alllll week. nice and deliciously.

i’m starting off with something not really hack-related (oooh god forbid) but interesting. it’s a movie based on google becoming a huge-ass conglomorate and wiping out media. very cool and post-apocalyptic kind of feel to it. watch it here and thanks [toto]

now onto some beastly links!

add an auxilary jack to your car [matt]
google maps wallpaper (whatever, doesn’t top my hilary duff wp)
open systems for car computers? oooh, i smell innovation and trouble.

looks like we got ourselves a trend going! more wallpaper from [jamie] and [blackzero]
god, i might have to make this a weekly segment on mondays or something!

uhhh, robot paintball? is it really necessary? [magnus]
dvorak says apple moving to intel will harm linux. nobody gives a shit. stop whining!
…though he could be right.

::sigh::

Hackaday Monday Sipping

monday sipping

well good morning hackaday readers. it’s monday. we’re all back at the office/classroom/jailcell so we know you are dying to get a few good tidbits of information in before you start having to work.

got a cat? maybe, maybe not. either way, this guy has a facial recognition door for his cat. insane eh? very cool though. maybe he should use it for humans.

Also, in other tech and hackery news, there’s still some major concerns over google’s way of storing your information and preferences. I can see a cause for concern but whatever, get over it. Not only that, but it’s true that last week South Korean hackers 0wn3d microsoft’s msn site and planted a password stealer. Very nice work.

Also, a new internet possible? I scoff at the idea, but embrace it at the same time. This time, it’s based on RFID tags.

Slashdot also had a cute little link to howto build your own linux distro. hackaday linux? vince linux? sendustodefconthisyear linux? hmmm, maybe. depends how big of a fan of work you are.

This is really cool in ways. A Judge threw out a dude’s DUI charge because he could not provide the man with information on how the breathalyzer works. The company wasn’t too big on giving their information to the state. A new legal defense? maybe. I think we need more open-source things from everything to code to information. Demand it to be public!

And one guy is selling every issue of WIRED on eBay. Does anyone care? Mmmm.

Also, a monday morning wouldn’t be complete without fun tidbits right? So here’s a picture for you to gander at: Pete Cabrinha riding a 70ft wave. The largest ever. Jesus God I’d be scared.

And may I reccoment a good site to visit? PWOT is packed with humor to the first degree. Tons of content and the forum is nice. I highly reccomend it during work or free time.

Now go brush up on Aristotle and enjoy your monday. Hopefully by now it’s a bit better. fool.

3D Scanner

spline scan

SplineScan is a cross platform 3D scanning solution. While the target object is rotating on a motion controlled turntable a laser is projected on it. A camera collects images of each step of the rotation. Using simple trig the individual frames’ line data can then be used to construct a 3D model. Andrew Lewis is in the process of porting the model generator to C from VB, but it can already be run in Ubuntu using WINE. If all goes well he will be doing a live demo at LUGRadio Live with detailed source to follow soon after. He expects the final scanner to only cost approx. $90.  Sounds like a lot of  fun. Thanks for sending it in Andrew.

good morning hackaday readers. it’s time for some fresh links to soften the blow of last night’s hurrah of binge drinking. so let’s continue shall we? I’m hittin you up with some goodies today.

yeah it’s old, but it’s still cool right? [musschrot]

Lava Lamp Random Number Generator

lava lamp

That title is really misleading; this hack doesn’t require a lava lamp… anymore. I initially went googling for a 1996 project at SGI that generated random numbers by taking photos of a lava lamp. The lava lamp was chosen because of its chaotic nature. I was suprised to find that SGI had patented/trademarked the lavarandtm technology. The system required you to use IRIX, took up a lot of space, and because of patents wasn’t easy to implement. In 2000 the engineers behind the original decided to develop an open source alternative know as LavaRnd (note the capital “L” and “R” ;-). [Editor’s note 2025: The domain has been taken over by an online casino.]

This iteration doesn’t use a lava lamp. Its source of chaos is camera with the lens cap on. The gain on the CMOS sensor is cranked all the way up to create a really noisy image. The image data is then sent through an algorithm to generate the random numbers. If you want to see the original project you’re going to have to ask the Wayback Machine.

Electric Starter Powered Kart

electric starter kart
Taking a cue from bar stool racers, Robert Lee built this kart using a Honda starter. The frame is constructed out of PVC with steel reinforcement. Notice the forced air cooling. Along with the kart details he’s got links to PDFs about building barstool racers and PVC frames on the site. Be warned: Tripod sites will make you envy the blind.

[thanks john kiniston]
