CupCake CNC Kit

cupcake

The CupCake CNC Kit is the flagship product of MakerBot industries, a joint venture between [Bre Pettis] and [Zach Hoeken]. At $750, it comes with all the motors, belts, body pieces, bearings, belts, and other pieces to assemble it. You could be printing your own 3d objects in a matter of hours with this. 3D printers with only slightly larger capacities can run thousands of dollars. The only advantage to some of the commercial products might be resolution. They don’t give much as far as technical data as the unit isn’t available yet. They should start Shipping before April 15th, so they can’t be far off. This could possibly be a competitor for the RepRap. Since RepRap doesn’t offer a complete kit, we’ll have to speculate. We’ve seen estimates from $500 to $1000 to build one.

Ultra Mouse Modification

When traveling with a laptop, we often find that the list of peripherals that we have to attach can get pretty long. Especially if it is an older laptop without wireless built in. [Dawning] has taken steps to consolidate some of his peripherals(registration required)by cramming a USB hub and a wireless card into his mouse.

He started by dismantling a USB hub. After placing the board in the mouse to see how it fit, he realized that he was going to have to reduce the size. To do this, he removed the USB slots themselves. This forces him to wire things directly to the board, but saves a ton of space. Next, he took the guts from a USB wireless adapter and wired them up. The decorative LED in the mouse was then moved to the wireless card. This way he could see light flicker with his network traffic. At this point, that’s all he’s added, though there’s still plenty of space for other items. He notes that he’ll probably add some storage or a CF reader. The only problem he has encountered is that his mouse tends to get warm during use. What peripherals would you put in there?

Update: [Dawning] let us know that he didn’t actually remove the LED from its original location. He connected a wire from the wireless adapter that causes the LED to short when traffic is going through. Also, there’s a video which you can now see after the break.

Glowing Patch Cables

[youtube=http://www.youtube.com/watch?v=zi3lpVzM-bM]

[Sleepydog] just sent in this cool video of a patch cable he made with a built in EL wire. He’s using a Power over Ethernet router to control which ports have power. He states that this would allow easy identification of specific cables in the mess. While the proof of concept seems completely functional, and the idea is nice, we have to wonder if the cost to put in all the extra hardware would be worth it. Each cable would have to have its own inverter, not only driving up cost, but possibly adding interference. That does not mean we don’t want this desperately, we do. But we want it just because it looks cool. He needs to choreograph this to some music now and make his entire server room into a fancy display.

RFID Controlled Phone Dialing

In an attempt to create an easier to use interface for the elderly, [Stephen] has put together this phone prototype which uses RFID tags to dial. It is common for our motor skills and eyesight to deteriorate as we get older. There are special phones out there, but generally the only changes they make are enlarged buttons and louder speakers. [Stephen] had the idea to make a system where an elderly person would hold up a picture of the person to the phone and it would dial. He picked up an RFID card reader and an Arduino. The code for the RFID reader was already available, and with minor modifications to prevent multiple swipes from hand tremors or slow movements, he was able to get it working pretty fast. The Arduino then sends the data to an ioBridge to make the call.He’s using Google voice to physically place the call, so you could probably adapt this to other services as well. You can see a video of it in action after the break.

AVR HV Rescue Shield

While playing with an ATmega168, [Jeff] programmed the RSTDISBL fuse bit. This pretty much makes the chip useless in most cases. [Jeff] didn’t want to give up on it though, so he built a system to program it using the rarely used high voltage parallel programming mode. He used an Arduino, a few lines of code and a few spare parts to make it. After sharing the idea with some fellow programmers, he decided to make an Arduino shield specifically for this purpose. You can use this to reset almost any fuse to rescue a chip. If you are a die hard AVR person and never started using Arduino instead, the STK500 actually has this built in.

3rd Generation IPod Shuffle Teardown

You should all know the drill by now. New electronics hit the market and someone has to post pictures of it spread open bit by bit. The new shuffle is no different as iFixit shows us. There are some very nice pictures of the entire process. As you can see, most of the space is taken up by the battery. The thing that is probably most striking here is the main problem that many people have with it; there aren’t any buttons.

Laser Etched Kindle 2

kindlesketch1

After seeing the xkcd comic where they call the Kindle2 the hitchhiker’s guide, [Ladyada] couldn’t help but laser etch the Kindle 2 with “Don’t Panic”. We think it looks pretty good, if a bit bubbly. You can see the video of the entire process after the break. Now that xkcd has infiltrated our interwebs, hearts, and minds, maybe he can put just a tiny bit of effort into learning to draw. If you don’t have access to a laser etcher, you could always make your own. Just be careful you don’t accidentally go full out and cut your kindle to shreds.
