MagneBike - Magnetic Wheeled Robot

 

The MagneBike is an interesting magnetic robot that is surprisingly flexible and can maneuver some crazy metal geometries.

“Locomotion Concept and Robot Design

  • Two wheels in a motorbike arrangement: better adaptation to the surface (flat or curved).
  • Magnetic wheel unit including lateral lifter/stabilizer arms. The lifter functionality helps to pass over step obstacles. The stabilizer functionality allows to drive sideway.
  • Five active DoF: front/rear wheel, front/rear lifter, steering unit.”

Electron Microscope Image Capture with an Oscilloscope

at 2:06 pm. Filed under Computer Hacks, Insane Equipment

 

What to do after you get your hands on a discarded scanning electron microscope. Ben Krasnow from Applied Science took the signal directly out of the device and fed it into a DSO. He was then able to capture it at a much higher resolution than is displayed on the original CRT that came with the unit. The results are incredible.

Self-Balancing Raleigh Chopper

 Self-balancing Raleigh Chopper

 

It isn’t a simply task to make a self balancing anything. But if you are thinking of taking on the challenge has documented his design details for this Self-Balancing Raleigh Chopper that could give you a head start.

 

“Data from the IMU is read by the Arduino Mega 1280. I use a Mega 1280 because they are a lot cheaper online than the 2560, and about the same price as an Uno. They have several hard wired serial outputs which means I can conveniently use one of these to send motor control data to the Sabertooth 2 x 25 Amp power controller, and another to send data to the serial-LCD screen. The Deadman switch and steering buttons (actually brake levers from children’s e-scooters) when pressed will connect their respective Mega pins to ground. The deadman is for safety, if you let go of it all power to the motors will stop after half a second. Digital Pin 12 is connected to an LED. This LED stays lit on startup and goes out after a few seconds when the machine is ready to be brought “level” at which point it will start to balance itself. The potentiometer in the diagram is actually on the left handlebar and is a Magura 5K potentiometer “twist-grip” throttle handle designed for electric vehicles. Turning it makes the machine lean forwards a little, and so it starts to roll forwards. Let it spring back and machine will lean backwards a little and slow down. It makes a very effective method of controlling speed (as well as simply leaning like you would on a Segway).”

The Combinator – A Comparator Combination Safe

at 8:40 am. Filed under Electronic Hacks

The Combinator - A Comparator Combination Safe 

 

If you have some valuables that you need to keep safe you lock them in your safe (as the name implies). It probably has a dial that is used to dial in your secret combination. The Combinator is A Comparator Combination Safe just to spice things up a bit. You won’t find a microcontroller in this device even though it is an electronic safe, instead it uses all analog electronics to get the job done.

Shoulder Mounted Arduino Controlled Skull

Shoulder Mounted Arduino Controlled Skull

 

Steven from Rimstar.org built an interesting spooky Halloween skull to scare anyone who walks by. The video below goes through the construction details.

“Two heads on a body are scarier than one so for halloween I mounted an Arduino controlled skull on my shoulder with the electronics in a backpack and a hand controller hidden in my hand with the cable running down my sleeve. The jaw opens, the eyes light up and it makes a scary sound.

The biggest issue I ran into was getting a sound synthesis that could be done by the Arduino while still using a servo. Most sound libraries I found either conflicted with the servo library or required use of an abstraction layer.

Luckily the Arduino comes with a tone() function that uses simple PWM to make an 8-bit type sound that did the job while not conflicting the the servo library.”
