Omnidirectional personal transport
[Dan] sent us a link to this Honda U3-X personal transport device. It’s kind of like a Segway that can move in any direction but our head already hurts from the thought of going over backward on one of these.
How light bulb filaments were developed
Now that incandescent light bulbs are about to be outlawed here in the US, we thought you might enjoy learning how the filaments were developed. This another video by [Bill Hammack], the engineer guy, and we’re big fans of his work.
Wooden stove reflow
Who needs a PID controlled skillet when you can reflow on this wooden stove? Well maybe not reflow, this is more of a salvage operation.
Javascript control
We’ve seen more than enough Arduino controlled outlets. But if you’re interested in using Javascript to control the Arduino this post may be just what you’re looking for.
Sledgehammer keyboard
[Taylor Hokanson] built a qwerty keyboard that you hit with a sledgehammer. Enough said. [Thanks Larry]
Definetely gotta get one of them sledgehammer-operated keyboards. Wonder if they make any models for gamers? And what’s next to come? Horse-operated mouse? Sweet!
So will filament bulbs become a black market item in the US? (the pun was unintended :p)
Sledgehammer keyboard? Love it! An accompanying touchscreen will probably need a bargepole to use, or a human pyramid to reach the top corners.
Love the keyboard. I think I want one!
I did not know about this incandescent light law thing. Wouldn’t that be stupid to do if everyone used CCFLs? They are great to use for like one spot in your house but the big 1. Mercury I think is worse then the pollution given off by the electricity by incandescent lights. 2. Some lamps don’t work with CCFLs because of the inverter. Especially the adjustable ones.
THAT SLEDGEHAMMER KEYBOARD NEEDS TO BE ALL CAPS ALL THE TIME!!!
While the stove very likely burns wood (a “wood stove”) is is not at all likely to be made of wood (a “wooden stove”).
That’s a cast iron stove, or a wood stove, but not a wooden stove. ;)
CFLs are highly inductive too. Good thing LED sources are improving and becoming more affordable.
Talk about “mashing keys”!
sweet on the honda thingy. Although it did win an award from Time magazine back in 2009 and also has it’s own wikipedia page already.
Oh, and it’s not for sale either.
Thanks for keeping us current, HaD ;-)
that’s a mallet.
@Alex: I can’t stop thinking the same thing. A *wooden* wood-burning stove would be a rather poor idea.
Pretty sure that’s a rubber mallet, not a sledgehammer.
Great idea of desoldering those displays on the stove – got a handfull of those displays, they are pretty sweet as they have a built-in character generator :-)
Do those trendy toe cover sock things come with the U3-X?
That’s a mallet, not a sledgehammer. This is Sledge Hammer: http://www.imdb.com/title/tt0090525/
I’m glad the govt. is finally doing things like making light bulbs illegal. I’d hate to have to think for myself.
Not to mention that CCFL light bulbs aren’t recommended for enclosed spaces and humid areas such as the bathroom, last I checked.
Plus, the WORST thing I’ve ever seen an incandescent bulb do is break, or pop loudly when it blows out. I had a house that regularly made CCFL bulbs BLOW UP! Literally, the glass would shatter unexpectedly.
A few months ago, in a different home, I smelled electrical smoke, but couldn’t figure out where it was coming from. Thankfully, I turned off the light when leaving the room. When I returned, the bulb made a horrid buzzing noise and was making all the lights in the house flicker. Sure enough, after turning off the light and checking it, there was a spot melted through the plastic on the side.
I never have figured out why everyone thinks they’re so great.
I have never personally had any issues with CCFLs.
I haven’t ever used the cheap rubbish that they practically give away at supermarkets and places though.
Not got any lights that aren’t low energy in this house (apart from one desk lamp).
I thought the same about the honda U3-X, bit old now.
That keyboard is pretty darn cool though.
How are we going to brood our chickens, without warming lights. The government banned heating pads that give heat. Now the wimpy-ass things shut off after just 2 hours. It’s early spring, seeds to sprout under controlled conditions, heat etc.
Yet they can’t ban uninsulated hot water pipes, or globe lights outdoors.
Wack-a-Mole data entry. Elephant keys to go with the elephant-toilet, look it up. Definitely over the wimpy water toilet limit. Looks like a 2 inch water line and 6 inch sewer line.
“[Taylor Hokanson] built a qwerty keyboard that you hit with a sledgehammer.”
Correction, “[Taylor Hokanson] built a qwerty keyboard that you hit with a sledgehammer and it won’t break.”
Lizardb0y said it before me. That’s a rubber mallet, not a sledgehammer.
@ echodelta
In Europe, most lightbulbs are already illegal. Of course, it’s perfectly fine to sell heatballs, which merely produce light as a byproduct, and which are produced with a standard E27 socket.

As a side note, I see that heatballs are also being held (illegally) by local government… odd.
how is mercury worse than wasting more energy? the mercury came from this planet, not like we mined it from asteroids(or Mercury) or made it by subjecting dead babies to high pressures and radiation..
That actually does suck about the 100 Watt bulbs, I have yet to see a CFL last more that a few hundred hours, wether they be the cheap $1 ones or the exspensive $5-10 ones. There’s always one part of the inverter circuit that goes AWOL, and usually in a fantastic fashion. I have seen some explode (a small pop really), briefly catch fire, and blow puffs of white smoke. While other just fail to work altogether. Not to mention that the vast majority of them get just as hot as an equiveleant incandescent. Also, they are big and don’t fit in most fixtures, have inferior light, take forever to light fully, they don’t dim very well or at all (depending on the type you get), not to mention the environmental disadvatages, they usually contain lead, always contain mercury, and they are damned near hard to recycle. Most will end up in land fills where the lead and mercury will be allowed to escape and leak into the environment. They cannot be put in trash bins, they are hazardous material and need to be treated as such, but people won’t do that.
In addition, I myself use 100 watt bulbs extensivly in my haunted attractions because they are dimmable and cheap (they also look better that a CFL when your trying to do a vintage theme). I hope they will come up with a way to license certain people so they can buy these types of bubls for these special cases.
love the keyboard. gives new meaning to “hit any key…”
the U3-X is very nice and looks simple but it keeps on giving me headache on how the smaller wheels around the larger wheel are driven.
anyone please shed a light on this?
“How is mercury bad?”
Well, don’t try smoking it.
mercury is bad because it go into the water supply.
Yeah, it’s bad because we don’t put it back into the same place we got it from.
For the mallet keyboard, the spacebar should be a big pad you jump on. For extra loudness.
I don’t see the Honda U3-X as anything other than a technology demonstration. For practical purposes I’d rather have a Segway, or a YikeBike.
Also scuffing my toes on the ground to turn (watch the video closely) is not something I’d like to try at high speed!
