Check out this cool Laser Cut Hand Bowl Instructable, I can just imagine a ton of laser cutters running today cutting this design out. Penfold Labs designed this using a number of different processes described below. If you are interested in purchasing one instead of building one you can get one in the Instructables store. “Here’s a small bowl I made from interlocking layers of birch plywood. I designed it using Poser, Blender and Autodesk 123D Make, then used a laser cutter to precisely cut all 40 of the pieces. The bowl stands at about a foot in height and, despite being very light, is sturdy and extremely well balanced so it won’t topple over when filled.”

Thanks to Daniel Kramnik who is a high school junior from Massachusetts for sending in his award winning DIY Digital Salinometer project. If you have never heard of a Salinometer before you can learn more about it here. The system is easy to troubleshoot since it is completely modular, since it is mounted to a piece of acrylic you can trace out circuits from the front and back of the design modules. “This project was built for the Water Quality Science Olympiad event. The rules manual just said “build a salinometer”, so this is what I came up with. The obvious choice, of course, is a simple mechanical hydrometer with maybe +/-5% salinity accuracy in the best case. This electronic solution (hehe!) has a theoretical accuracy of +/-0.0014% salinity, but some serial dilution is required to bring the sample into its range.”

Are you getting fed up with your Fan’s speed? If Yes! then here is the solution. Circuit-projects brings a fantastic tutorial that will help you to alter the power of your Fan’s motor winding. This will help in increasing your Fan’s speed. Even you can monitor how fast the spin of your fan. |

If you love taking pictures you either have or need to purchase a Intervalometer, if you love DIY electronics you should look into building your own. Nice thing is there is a great new Arduino based DIY Intervalometer to get you started. ”After some thinking, I convinced myself that I needed a navigating menu and at least these 4 different operating modes:
The input mode is by far the trickiest one and the one that requires most coding, the others are fairly trivial since they require small or none user interaction being mostly informative. In fact, during input mode, Intervallino has to display the correct information depending on where we are in the menu, wait for the button inputs and respond to them accordingly.”

Glen Johnson built this Frankenkindle to help out his sister who has cerebral palsy. It uses some controls that were scavenged from a different device which has big easy to press buttons. Buttons on the added keypad have been made to activate macros that perform features on the Kindle. It is a bit slower than the normal Kindle controls but since this is a book reader and not a video gave player speed is not the most important thing. For schematic and code for the project you can find it here (PDF).

Look on this crazy digital Foosball Table connected over Internet. You can do lot of amazing things, once you’ll be able to get this tble online. There are number of salient features of it like: - The Blueprint - The Mobile WebApp - The Agency Foosball league You’ll require a very few components to build your own Foosball Table like – Arduino Uno, WiFly Shield, Stackable Header Kit and Zeitschalter mit IR-Lichtschranken. You can collect all the design steps of this interesting project here. Checkout for more details at Github and Wiki and watch this documentary below:

You might remember the Top 10 WALL-E Hacks post that we made back in 2009? Well the DIY WALL-E builders are still hard at work. Have a look at the video above showing the tracks that Michael from the WALL-E Builders group is working on. UPDATE (January 6, 2012): Thanks to Michael for sending in some of the build pictures.
