Video: African Bike Repair With Home-Made Tools

Mohammed is a bicycle repair man in Nairobi, Kenya. His repair stand is the dirt floor, and his tools are home-made. His wheel-building and truing machine is… Amazing. Check it out:

That stand looks a lot better than the ones they use in my local bike shops — it seems like it would last forever. Even Mohammed’s spoke key looks home-made, to a superior design than any I have used — the slotted ring acts as a lever and makes it easy to locate the right sized slot for the nipple you are twisting. The price to have a wheel trued by Mohammed? 10 Kenyan Shillings, or around 13 cents US.

Then we see his freewheel cassette remover. Taking one of these off is near impossible without the right tool, so Mohammed built the right tool. The huge metal mitten grabs the cog-teeth an a screw locks the cassette so it unscrews instead of just spinning.

Innovative stuff, and a lesson to you next time you go to the bike shop just to have them change a tire. Quit being so lazy and do it yourself.

Notion Ink smartpad comes with Tegra, aims to be first Pixel Qi device

Now here’s a way to excite all the tablet naysayers. Slap that ultra-efficient Tegra chipset inside a 10.1-inch touchscreen tablet, make the display a matte (yay!) Pixel Qi slice of glory and then stand back as all of geekdom rejoices. We’re still only looking at renders, but this device is all set to make waves at CES with an impressive spec sheet that also includes WiFi, Bluetooth, UMTS/HSDPA, and A-GPS on the wireless front and connectivity via USB, HDMI, and a 3.5mm headphone jack. The most important thing is still that display, though, whose efficiency leads to the unnamed device boasting 48 hours of battery standby juice, also good for 8 hours of HD video playback or 16 hours of WiFi-enabled Engadget reading. Driven by a default (for now) Android UI and supposedly capable of running three simultaneous 1080p streams with little frame loss, this should be one hot piece of kit come January. For now, we have another shot after the break as well as the full data sheet.

DIY X-Ray Camera Less Dangerous Than You Think

xray1

A small, often forgotten, but significant advantage of digital cameras is that they can be fed through countless airport X-ray machines and the pictures feel no ill effects. Try that with a film camera (or even the bag of film you plan to use on your vacation) and things quickly start to get cloudy. Literally.

That’s because X-rays expose film just like light does, although the X-rays don’t get blocked by the camera body quite so well as the visible spectrum does. This is the trick that PopSci’s Theodore Gray used to make a DIY X-ray camera.

In fact, you don’t even need a camera to try this. Take a sensitive piece of film — Gray used ISO 3000 Fuji instant film — and wrap it in something that will keep the light out (do this in the dark, of course), like tinfoil.

Next, Gray put and old butterfly-shaped earring on top of the package, and hung a radium button (saved from an old science kit) above that. After a day and a half, he developed the film in a Polaroid machine and there on the sheet was a photogram of the butterfly.

Amazingly, you don’t even need the radium button. Although glowing, radioactive watch hands would be even quicker, if you are patient (as in, several months patient), you can use ordinary sodium-free salt to beam particles from decaying potassium-40 at the film.

You could actually try this at the airport, packing up your wrapped film and trinket together in an envelope, say, and letting it run through the X-ray machine. Just be prepared to do some fast talking. And don’t tell them I sent you.

OS X Surpasses Windows Market Share (On Phones)

chart_2

A new survey from Comscore shows that the iPhone has jumped ahead of the ailing Windows Mobile in the US. Comscore measured actual ownership instead of sales figures (as in “What phone do you use?”). RIM’s Blackberry still comes out on top, but in October  Apple jumped ahead of Microsoft, with almost nine million users to Windows’ 7 million.

And remember, Apple has just the three generations of the iPhone and the iPod Touch, while Windows Mobile has been shipping on a whole range of devices for several years. Interestingly, although Palm comes in ahead of Symbian and Google (Android), these figures discount the Pre WebOS as there just aren’t enough Pres out there to show on the charts.

With manufacturers like HTC, traditionally a big WinMo handset maker, defecting to Android (HTC makes the Nexus phone for Google), Microsoft had better watch out. As the mobile market grows and slowly pushes out the desktop and laptop computer, Windows’ stranglehold on the computer industry will continue to slip.

ASUS Eee PC 1005P/PE with Atom N450 and 12.5-hour battery breaks cover

You do realize that all those Atom-based netbooks on sale for the holidays will be abandoned entirely in January right? Go ahead and pull the trigger for that “new” ViewSonic netbook if you must, just realized that you’ll be running last-gen hardware in less than a month if rumor, innuendo, and leaks all converge with the release of Pineview netbooks as expected. More details have appeared today at retailers listing specifications and pics for the unannounced ASUS EeePC model 1005P and 1005PE. Sporting the Eee PC Seashell design, we’re looking at a pair of 10-inch LED backlit displays with a 1,024 x 600 pixel resolution, Intel Atom N450 proc, 1GB DDR2-RAM, and a Windows 7 Starter Edition preload riding GMA 3150 graphics — a slightly faster version of Intel’s G31 based GMA 3100. The PE model sports a bigger 250GB hard disk and higher capacity 6-cell battery for a reported 12.5 hours of go-go juice thanks, in part, to the more efficient N450 CPU. Expect to see these Eees get official with price and launch date any day now.

IEEE begins work on new cellphone battery standard, we circle 2029 for ratification

You’ll excuse us for poking a bit of fun at the IEEE, but after it took seven years to finalize a wireless standard that didn’t change for most of that time, we have to wonder how long a new battery rulebook is going to take. IEEE Std 1725 is the current set of commonly agreed rules, in effect since 2006, but apparently “the cellular industry has grown tremendously since then” and our needs as consumers have changed. No kidding, 1GHz processors and 1080p video recording can kind of do that. The Cell Phone Battery Working Group (a real entity!) will hold its first meeting on the topic in February, and the final outcome will lay out up-to-date rules on the requisite quality, reliability, construction, and discharge characteristics of modern cellphone batteries. Let’s hope “smartphones that last more than a day” figures somewhere on that list.

Google’s Nexus One lacks multitouch

Our buddy Tnkgrl just had a sit down with Google and HTC’s lovedroid, the Nexus One. She “wasn’t allowed” to take pictures or video but she came away with plenty of detail. The biggest point of clarification might not be what’s included in the handset, but what’s missing: multitouch. She confirms, “no multitouch support in the browser or in Google Maps,” just like Verizon’s Droid (but available on its European Milestone brother). The unit she tested included a 4GB microSD card, 1400mAh battery, worked on T-Mobile’s 3G only (AT&T is limited to EDGE data), and was “super snappy! Faster than the Droid.” She also noted “gold contacts” along the bottom edge presumably for a docking port thus jibing with whispers of a Nexus One Car Dock accessory. Now hit the read link for all the details if you still have the strength.

P.S. We should probably clarify that while the Google Apps tested don’t respond to multitouch, the OS and hardware are presumably multitouch capable. See our previous exhaustive analysis of this topic if you’re wondering why.

Philips LED Concept Stores

phillipslightstores_500x667.jpg

cnet asia (crave): LED lighting products for the home are finally heading Asia’s way. The Ledino collection, under Philips, will be its hero product when the Dutch company sets up its first exclusive Philips Home Lighting Concept Stores in Singapore come January 2010. This will be followed by four more before end of next year.

This initiative is part of the company’s direction for the region, clearly to increase sales through retail and distribution via Philips-branded showrooms. However, these will differentiate themselves by being set up to simulate realistic home environments, rather than cramp every nook and crany of a store with light fixtures.

The aim is to improve the consumer shopping experience in picking the correct lighting product for the different home spaces, said its senior manager for Corporate Communications at Philips Electronics Singapore, Lim Bee Hong.

China, which opened its first Philips Home Lighting Concept Store last year, will have 80 across the Mainland by this year. India has 33 stores, while Thailand will be debuting its first one this month.

Chumby One gets the iFixit treatment, greets world with a cute hidden message

We’ve already played with the Chumby One and fell for it, so it did hurt a bit when our friends at iFixit decided to rip this cute device apart. Actually, it wasn’t as heartbreaking as we thought, especially when the hackers spotted a cute message below the Kingston 2GB microSD card — containing the firmware — on the logic board, courtesy of Andrew “bunnie” Huang, VP Hardware Engineering and Founder of Chumby Industries. Other notable discoveries include a Freescale i.MX233 processor, Hynix 64MB DDR RAM and a removable “Ralink-based RT2571 USB Wi-Fi dongle” (note: extra USB port!). Feel free to check out the guts after the break — just promise you won’t cry or faint.

Verizon getting Palm Pre Plus and Android-powered Motorola Devour?

We’re still not totally clear on how exactly Verizon intends to enter (or rather, re-enter) the Palm stage in 2010; we know there’s definitely a WiFi-equipped CDMA Pixi out there that’ll likely find its way into Big Red’s clutches, but otherwise, we really need to wait for this event at CES next month. Well, maybe — we’ve got another little clue here in the form of some tips to PhoneArena stating that a “Pre Plus” has found its way into the carrier’s systems, which fits in nicely with info we’d previously received from one of our trusted sources that Verizon’s Pre would be somehow “different” from Sprint’s though we don’t yet know how. As far as we can tell, this isn’t the same as that WiFi Pixi (wouldn’t it be confusing if it was?), so we should probably expect at least two webOS models on Verizon over the next few months. In other news, that Motorola Calgary (pictured) appears to be shaping up as the “Devour” with a 3 megapixel cam and Blur running on Android 2.1 — yes, 2.1, not 1.5, which should give hope to CLIQ owners that an update is probably in the works. Finally, there’s talk of an LG VS750 in a mega-thin form factor running WinMo 6.5 with global roaming capability, but we don’t have a picture of that one just yet. Anyhow, back to the Pre Plus, we’re accepting all guesses as to what the “Plus” in the name might stand for — 16GB of integrated storage or a microSD slot seem like obvious candidates, but feel free to get creative with us.
