 Hershey Kisses Dispensing Robot _1 


This Hershey Kisses Dispensing Robot that duboisvb built will let you catch James Woods! This cute robot uses a Picaxe microcontroller project board and is programmed to drive in a heart pattern and drop kisses along the way.  A few gear motors are used to let the robot drive the pattern and a small servo is used to control the candy drop. A simple coaster wheel is used to allow the robot to be able to turn without steering.

Secret Room Behind Bookcase

 Secret Room Behind Bookcase


This is a great looking hidden room. It was totally designed and built using the DIY method right from the heavy duty Home Depot casters that were cut apart to make some big swivels to the door latches that hold the book case in place. The only thing I would change is the method that is used to unlock it. Currently you pull on a cable that is connected to a book, if someone was looking hard for something it wouldn’t take long before this book with table attached was found. I think a piece of upper trim that needed to be lifted would have been a bit better. I like the use of common door latches that are used to keep the thing in place, this would allow you to shut this door and have it latch just like a normal door without worrying about resetting it before closing it. Looks like the creator is storing a nice gun collection or looking to start a war.

Thanks to Trevor for sending this in.

Circuit Lab – Available Offline

at 12:01 pm. Filed under Educational


Circuit Lab is now Available Offline so you can design some cool circuits in your cabin in the woods. When you come back to civilization the your new creations will sync so that they are available online for collaboration and sharing.

“Our team is happy to announce that CircuitLab is now available offline! Our belief at CircuitLab is that your electronics design tools should be available to you wherever, and whenever inspiration strikes. With CircuitLab’s offline capabilities, you can now design, simulate, and save your circuits while you are not connected to the internet. (Some features, such as exporting rendered schematics, are currently only available online.) Once your computer comes back online, we will sync all your circuits with your account on our server. Offline mode makes heavy use of advanced features in HTML5 to further blur the distinction between desktop and browser-based software, bringing the best of both worlds to our more than 60,000 monthly active users.”

Arduino Spirograph

 Arduino Spirograph_2


The guys over at Whiskey Tango Hotel have made a Arduino Spirograph that will provide hours of viewing enjoyment. An Arduino controls the action, 3 motors spin mirrors and a laser is bounced from one to the other while they are spinning to produce a cool spinning effect. If you are interested in making one you can grab the code from the project page.

“For the project you will need a few items:

  • Arduino (I used the Nano pictured above; $9USD shipped)
  • Laser Diode (check eBay for red ones that sell for ~$1.50USD shipped)
  • Three DC fans or motors (I rescued three 24VDC instrument cooling fans)
  • Three small mirrors and double sided tape for each fan center
  • Three 10K pots (used to control the fan speed independently)
  • Three LEDs and three 330 ohm resistors
  • AC/DC Power adaptor (I rescued an 18VDC wall wart)
  • LM7805 voltage regulator to tame the output from the wall wart to 5VDC
  • L78L33 voltage regulator (provides a 3.3VDC for the laser diode)
  • TC4469 Quad Motor Driver to provide controlled power to the fans”


Everything is Spinning

Our crazy mad scientist friend Rick Crammond (MrfixitRick) had made a cool compilation of the last 5 years of his experiments. You will see some of the successes and failures that he has had over the years.

Mini Articulating LED Computer Lamp

   Mini Articulating LED Computer Lamp_2


If your life revolves around your computer a nice way to keep working in dim light is a must. If you can get your hands on a laser cutter this Mini Articulating LED Computer Lamp would be a great project to try out. The finished lamp can simply plug into your computer USB port, be careful though since USB ports can be damaged easily if you abuse them. If course you don’t need a computer around to take advantage of this nice lamp since you probably have a USB handy for charging your cell phone, MP3 player, GPS…

-14 gauge steel wire
-small machine screws and nuts (I used the smallest size I could find in my hardware store, you may have to adjust the hole sizes for the screws you can find). You’ll need 1/2 inch, 3/4 inch, and 1 inch long screws.
-small screw eyes
-rubber bands (4 regular sized)
-tar paper (or any black paper or thin plastic sheet)
-white fabric (synthetic is best because the edges get cauterized by the laser when cutting)
-1/8 inch masonite
-small gauge magnet wire
-good super glue
-Inexpensive USB LED computer light – for parts”
