Here’s a nice fluorescent bulb backlit frame you can make so that your firewood picture seems
to come to life! Thanks Michael!

Do-It-Yourself projects for low-cost, cool, illuminated photo and picture displays using easily available materials. All projects include detailed How-To’s, illustrations, and readimade versions for purchase.

Cool propeller clock you can make!

How this clock works:
A motor spins the “propeller”, and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion, but it works nicely.

If you want to build this clock, you will need a few things, including:
Skill with motors and mechanical things.
Prior electronic experience.
A dead VCR or floppy drive or other source of a suitable motor and miscellaneous parts.
A programmer that will program a PIC16C84 or 16F84 microprocessor.

Wow, check this gun out that William submitted. Thanks William!
Check out the photos and how it works.  Nice big ass capacitors, wow!

• Two coils are precisely pulsed in sequence (350 Amp peak) to fire a steel projectile
• Two infrared sensors detect the projectile position within the firing tube
• Controlled by a PIC microcontroller
• Powered by 8 AA NiCd battery pack
• Built-in battery charger
• Bar display tracks capacitor bank charge progress
• Battery and Fault LED indicators
• Laser targeting sight
• Makes no sound when fired
• Finally the device the whole world has been yearning for since the beginning of time!

Here’s the last DIY for year 2006!

Okay, we have seen some really cool Light Orbs while trying to make this Music Syncing Light Orb Alarm Clock.
We started with Tod’s creation and soon realize that 1 LED will not be bright enough in slightest light conditions though his Light Orb is tight let us say.
So we checked out RGB lights at Hackedgadgets.com. Which is cool and uses 4 Red, 3 Green, and 3 Blue LEDs.
Well during our google search for Light Orb HOWTOs, we came to the Ambient Devices schematic and their technical notes. Well it says that with the right voltage, you don’t need to use resistors.

We wanted to create a Light Orb that would be a mix of Light Orb, some cheap
Piezo music, and an alarm clock. We figured these would do very good Christmas
presents for our friends and family.

Nicely done Wii drum machine hack!

Bob Somers managed to turn a Wiimote into a drum machine using this custom script and GlovePIE. Video after the jump.

Now if you could just get two Wiimotes running at the same time, along with some sort of foot switch mechanisms for the kick drum and hi-hat, you’d have a full-fledged electronic drum kit. Anyway, we like the graphics of the Wii demo better. But both approaches look like tons o’ fun

Instructions:

With all the hacks for the Wii remote going around, I kept hearing people say they couldn’t wait until someone made a drum machine.

So I did.

To get this working, you first need to go over to either WiiLi.org or LiquidIce’s Wii Hacks page and get your Wiimote working with bluetooth. Follow all the great information they have to get your remote working with GlovePIE. Once your remote is working fine with GlovePIE, then your ready for the following files:

• Download WiiDrums.zip

NOTE: You’ll need the latest version of the .NET framework to run the Wii Drums program, so shame on you if you haven’t been keeping up with your Windows Updates!

Unzip those files to a directory of your choice and run the setup program. When you get a security warning, click Install anyway, sorry I haven’t paid Microsoft lots of money to be a “verified publisher”.

Once the program is installed you’ll see a program on your Start menu called DrumSounds.

Connect your Wiimote, load up GlovePIE, and run the WiiDrums.PIE script I included in the WiiDrums.zip file. Then run the DrumSounds program from your Start menu, and make sure it is the front-most program. Then just follow the instructions on the program and have fun drumming!

The guys Will at posted his howto on .  He shows us how to solder and assemble the Make Daisy MP3 Player from
scratch! Well, this MP3 Player has always been on our priority list for hacking and modding so
check it out and make one for yourself! We plan to hack it with some LCDs and more…

Here’s a cool upcoming technology that can change the world forever for you if you are blind.
It translates text into braille and lots of more features.

The bridge is a neat device. None of the technology is not revolutionary but the tiny package is impressive.

“When it is scanning the text in books or other presswork, it translates the text into braille, which is then displayed on its special screen for the blind to touch. At the same time, “Bridge” saves the text into the internal hard disk to be read later. In addition, the product can download data from the Internet. So that it can fit books of different sizes, it has been designed with a foldaway shape. The user can delete files on demand. In order to allow users more convenient reading, the Braille screen can display a column of words only. The device is easy to operate, with easily identified functional divisions. It is small and easy to carry, allowing it to be used anywhere.

How does it work? The braille screen works with electromagnetic or piezoelectric principles. When the current or voltage goes through every array of six stitches, the resulting rise and decline gives birth to braille. The product scans the original printed matter, then translates the images into analog electrical signals with an optical-to-electrical transducer. Finally, it translates the analog electrical signal into a digital signal.”

Here’s a cool little instructable on how to etch solder paste stencils at home.
I have been researching for home-made PCBs lately as Garrett’s always talking about it.
Anyway, we can refer to this when we make some custom boards.
