Robotic MiniPOV


Too lazy to wave around your miniPOV? I can relate! But potxoli took it a step further by building a Lego robot to spin a MiniPOV around: Awesome!



x0xb0x adventures!

I was supposed to have three pieces in the Columbia College A+D gallery show D.I.Y. show “pass it on” but the x0xb0x, spokepovs and mintymp3 decided instead to go on a road trip!

Wave Bubble RC1a released

I’ve updated the Wave Bubble schems and board files to RC1a which fixes the 2 or 3 bugs notified to me. Check the d0x out from the download page



x0xb0x boards available

I’m back from a successful endeavor at SXSW interactive, and I’ve uploaded x0xb0x board layout files to Sourceforge. You can grab them from the x0xb0x download page To generate Gerbers, use EagleCAD

If you just want to buy the PCBs, they are available for sale in the webshop!



Do not stick hand or eyeball under laser

Information is power.

In this case, exactly 35 Watts of power!

Check out the new Laser Information pages for all of your $20K laser cutter setup needs!

Its another Wiki embedded page: it looks like a normal web page but if you click the link at the top it will take you to the Wiki where the data is kept. That way, the 99% of people who just want the info don’t have to deal with the strange look of a wiki.



Embedded wiki for finding parts

I’ve decided to experiment with the Wiki architecture for dynamic/collaborative documentation. For my kits and projects, wiki’s make less sense than forums, but a lot of people email me with resources so the “parts procurement” page that has been so popular that I’ve turned it into embedded content.

Now when you have a suggestion for a company to sample from, you can just edit the wiki yourself!

(apply google ‘(ladyada.net adafruit.com))

I spent a little time and added ‘Google custom search’ to the top right corner of nearly everything on ladyada.net, it will search both sites for everything you want to find here!

It seems to search the store, blog, forums and all content: hooray!

x0xb0x in Circuit Cellar!

…well, kinda


Back pages of recent C.C. have this ad.

Turns out this “dirt-cheap and not very english-speaking” PCB fab house in China needed some clip art and thought this circuit board fit the bill:

FYI, x0xb0x’s are actually manufactured by Advanced Circuits in Colorado, which is my recommended PCB house: they have not let me down ever!

’06 AVR contest winners

Nothin’ brings out the best in microcontroller design like a $5K grand prize.

This Dog Seizure meter only took honorable mention, but the best thing about all these projects is that they are somewhat documented! (When they work at all)

Randy Cohen’s got my back!

New York Times’ “ethical advice” columnist Randy Cohen gives his take on RF jammers (like, say, Wave Bubble) in this week’s NYT Magazine:

The Ethicist
The Phone Ranger

By RANDY COHEN
Published: March 4, 2007

Each day people are more brazen and rude with their cellphones. My husband bought a device that can block the signals of cellphone users who annoy him, although he knows such gizmos are illegal. Isn’t his vigilante behavior worse than that of the rudest cell user? — Name Withheld, Connecticut

Your husband may not stifle someone’s behavior merely because he deems it annoying. So capricious a standard would mean constant peril for people who talk baby-talk to their excessively small dogs. Living among other people requires us to tolerate conduct we find vexing.

Or so my head tells me. But my heart says, Your husband is a hero, an acoustic Robin Hood who robs from the rude and gives blessed silence to the poor in spirit.

I propose these guidelines: If someone is yammering into a cellphone on the pavement and you don’t like it, walk away. It is open public space, and opinions vary about its use. Some people place a lower value on quiet than on prattling about what they saw on TV last night. (An immutable law of nature: The louder the phone voice, the duller the conversation.)

But if someone is using a cellphone in a closed space — on a commuter train, in a restaurant — from which you cannot escape, let the jamming begin. We properly limit our freedom when we harm others. It is the cellphoner’s jabbering that prevents you from reading your book or thinking your thoughts, not the other way around.

Those who control shared closed spaces — a theater, a physician’s waiting room — should jam and disclose. Post a sign that says “No Cellphone Service” so people know what they’re getting into. Anyone anticipating an urgent call can ask to use the land line. For decades, doctors on call did just that, and we all survived. Sadly, this solution — ethical, courteous and humane — is frowned on by the F.C.C., but tell your husband I’ll visit him every week in jail.
