Keyboard Chair

_Keyboard Chair

 

Doesn’t look all that comfortable but this Keyboard Chair sure is unique. I am curious where all the keyboards came from? I hope they were salvaged but they were probably purchased for this sculpture. They should have completed it by mounting a right and left side of a split keyboard on each of the arm rests. The chair could then have a single keyboard USP jack and actually be used to type.

Make a Bubble Tube Lamp

at 7:45 am. Filed under DIY Hacks

 

You may have seen these bubble lamps on some old ornamental items such as jukeboxes. It uses methylene chloride which boils at a low temperature. The effect shows a bubble that forms at the bottom next to the heat source and as it rises the bubble gets smaller and smaller until it simply disappears.

Raspberry Pi 3D Printer Demonstration

at 2:14 am. Filed under Complex Hacks, DIY Hacks, Electronic Hacks

 

Jon Wise demonstrates his Raspberry Pi 3D Printer, he is using a pen in the demo but it can use an extrude to print items. The mechanical movements leek very complex when compared to a standard XY table that is controlled using 2 stepper motors. The Pi has enough number crunching ability to get the job done though. I can’t wait to see this printing a complex shape, the movements are interesting to watch, it reminds me of the robot hands that use angular joints to move around.

Laser Cutting 3D Objects

 Laser Cutting 3D Objects

 

When think of what a laser cutter can do you normally think of cutting things and etching surfaces. I never would have thought of making something 3D other than making notches that can link together. This video shows a technique that holds the material being worked over the main laser cutter bed using some stilts. Cuts are made in acrylic and since acrylic bends when heated the laser is used to slowly warm the material where it is needed to be bent. Since the work is sitting off the bed it can droop when heated. To see more information on this Laser Cutting 3D Objects method have a look here.

AZIZ – LED Microscope Illuminator Project

AZIZ - LED Microscope Illuminator Project

 

While watching the video I was wondering why there was so much complex electronics for the AZIZ – LED Microscope Illuminator Project. I was thinking that a simple dial to vary the intensity would be all you would need. If you are thinking the same thing have a look at the video starting around the 4 minute mark. By having modes that allow you to spin lighting patterns and vary the light between the diffused and bright white LEDs you can enhance chip markings tremendously.

The system controls 64 LED using a Texas Instruments TLC59116 constant-current PWM LED driver chip, and an Atmel ATTiny1634 8-bit microcontroller. Code and schematics are available if you would like to make your own.

Thanks for the tip Stephan.

Rave Shades – LED Glasses

Rave Shades - LED Glasses_3

 

These Rave Shade – LED Glasses look like a ton of fun. They are Arduino based and use 74HC595 shift registers to light all the LEDs. At first I though it was a silly design since with a PCB sitting on your face you would not be able to see anything. But later I saw the small circles that are cut into the board which allows you to presumable see most things in front of you. To program new pattern some computer software is used which generates the pattern code to be downloaded to the Arduino. eXtremeSomething is selling kits but he is waiting till 10 people pays for a kit before pulls the trigger on the order. Sort of like a mini Kickstarter (he lives in the UK and Kickstarter doesn’t operate there). Be sure to follow the project Facebook page if this interests you!
