Keeeb Organizes Web Clippings From Any Browser

Keeeb is a handy bookmarklet and web service that stores your web clippings into an easy-to-organize Pinterest-like page.

Once you create an account and install the bookmarklet into your menubar, you're ready to go. If you see something you want to save on a website, just click the bookmarklet and start gathering your content by clicking on photos or highlighting text. Each selection will give you a small popup to save the content to Keeeb, and a dropdown menu to select the page you want to save it to.

When it comes time to review your saved content, open up your pages on Keeeb's website, and go nuts by rearranging the panels and adding comments to your heart's content. Your pages are private by default, but you can share them to your social networks with buttons at the top of the page. Keeeb's design is Pinterest-like, and very nice to look at, so this could be a cool way to share bundles of links and photos with your friends.

The concept is pretty similar to previously mentioned Dragdis, but it works in any desktop browser through a bookmarklet, and stays completely out of your way when you don't want it around. It's certainly not as powerful as something like Evernote, and I wouldn't trust it with really important data, but for quick research projects or for a semi-private pin board of cool photos, Keeeb is definitely worth adding to your menubar.


Turn a Normal Pipette Dispenser to an Automatic Repeater

1st attempt:  At the beginning, I thought the pipette dispenser aspirates/ejects the medium inside the pipette by changing the pump moving direction inside the pipette dispenser. If I added a PWM circuit into the pump control circuit to control the pump moving direction (for example, when the PWM signal is high, the pump rotates to one direction, and when the PWM signal is low, the pump rotates to another direction), it might solve the problem. Unfortunately, the pipette dispenser does not work that way. After I opened the pipette dispenser, I found that the pump inside the pipette dispenser always moves to one direction, and the aspirating/ejecting is done by mechanically pressing the valves to change the air flow direction inside the tube. I have to design something to press the up/down button mechanically.

2nd attempt: I decided to use the available parts inside my lab to design a PWM circuit to control a servo to press the up/down button. The position holding time of the servo (the duration of pressing the up/down button) should be adjustable, and the rotation position of the servo should be repeatable. The circuit I designed contains two main parts: a PWM circuit to control the servo position and another PWM circuit to control the holding time.

Refurbish an E-Piano: Fix and Polish Broken Keys

Initially I wanted to buy new keys and just replace them by myself. But I quickly realized that new keys would cost twice as much as I paid for the whole piano, so I asked several piano restoring professionals how to deal with the problem of these ugly surfaces of the keys.

They all suggested polishing with car polish or something similar! So I went to a DIY store and finally bought a "repair set" for acrylic bath tubs. The set contained sand paper ranging from 400 to 1200. ( I am not sure if you have the same classification of sand paper in the US, for us 1200 is really super fine, it's pretty much the smallest grains you can get). Furthermore, the set contained a polishing paste and a polishing towel.

Additionally, I also bought a "sand towel" with 1500 graining which is the finest sanding available. 

I also bought a fixture for a round plate and a lamb wool towel to put onto the fixture. The whole thing could then be attached to the drilling machine.

In addition, I also bought PTFE paste (teflon / silicone paste) to lubricate the moveing parts of the keys again after I removed them and put them back.

Apart from that, you need a drilling machine, screwdrivers, a loooot of time and a room where you can store all the removed keys and the rest of the piano pieces.

Upcycled Auto-Watering Garden Aliens

These little guys are sure to abduct your heart.  They're simply out of this world!

These aliens work just like watering globes such as aquaglobes, but they can be made from recycled green glass bottles!

They are perfect for smaller container plants such as herbs or flowers, and excellent indoors and out!

Did I mention they are easier to fill than normal garden globes?  Yippee!

If you enjoy this instructable, please vote for it in the Gardening contest!

Here is What You Will Need:

Glass Sprite Bottle (other green glass bottles would work, but glass sprite bottles have the most alien-y shape and color)
Black Glass Paint (I used Martha Stewart Metallic Glass Paint in black nickel)
Small Tray for Paint
Sturdy Foam Brush
Contact Paper 
X-Acto Knife or Silhouette cutter
Loaf pan
Tray to keep bottles from rolling around (I used an old silverware tray)

Build this Easy, DIY Desk Lamp from Recycled Blank or Burned CDs

Remember when burning CDs was a thing, and everyone had stacks and stacks of blank or burned CDs stored on spindles? Well, if you still have some of those spindles and no need for the CDs anymore, this easy DIY project turns them into a fun desk or hanging lamp, perfect for your workspace or home office.

The project comes to us from the folks at Hack a Day's new Life.HackaDay page, and the video above does a great job of showing you how to build both types of lamps, the desk style and the hanging style. All you need in both cases is an under-counter LED strip-light, a ton of used CDs, and either some sturdy wire or a nice long rope to make it all work.

The whole process only takes a couple of minutes, and you won't even need any special tools. It's a fast and simple project, the end product doesn't look horrible, and a great way to put those spindles of blank or burned CDs you have lying around to good use. Hit the link below for more detail and photos of the finished product, all lit up so you can see what it would look like on your desk.
