Autopilot MEMs Robot

    When you don’t want to drive your robot wouldn’t it be nice to just point in a direction and have it go there? Well the issue is that every little bump and wheel drag will slowly adjust the direction so where it ends up after 50 feet will most likely not be where you intended. Iron Jungle from Whiskey Tango Hotel  used a LM303DLHC which is a Micro

VFD Clock

  Our friend Pyrofer wrote in about his new VFD Clock. “It sets itself via NTP and adjusts for daylight savings time so no buttons and it never needs adjusting. It can be monitored via SNMP for logging the temperature and checking system uptime. The entire SNTP stack was written from scratch and it all fits in one AVR 328P. For a screen I am using a salvaged VFD from

Sydney Mini Maker Faire

  Dave from the EEVblog checks out the Sydney Mini Maker Faire which was held at the power house museum. Quite a few 3D printers and robots driving around. At 5:45 there is a guy who does a brain wave scan of people, combines it with weather data and 3D prints a design that combines the two. At 8:30 you can see some rockets on display outside and a demonstration

Ultrasonic Range Finder with Haptic Feedback called The Bat Hat

  Jeff Buswell, Clifford Chou and Andrew Knauss from Cornell university made a cool Ultrasonic Range Finder with Haptic Feedback called The Bat Hat for their ECE 4760: Final Project.  “For our ECE 4760 final project, we designed and implemented an ultrasonic range-finding hat that uses haptic feedback to alert its wearer about obstacles in his or her path. The hat is equipped with an ultrasonic transmitter/receiver circuit, which is

Levitating Spinning LEDs

  Sam writes. “An electromagnet levitates a ring of LEDs attached to a coil. The LEDs are powered using a wireless power transfer from another coil under the electromagnet.  Levitation is achieved using a Hall effect sensor and a proportional controller implemented on a KA7500 SMPS controller. The wireless power transfer system consists a Class E DC/AC inverter operating at 800 KHz.  The LEDs can be rotated to give a

WiFi Robot

  Check out this great WiFi Robot project that used an app called Wifi Bot Control. “Features Uses WiFi only to control the robot and view the IP Camera stream Configurable camera URLs (up to 3) 3 Joystick Modes: Default, Simple Mode and Orientation Sensor Supports up to 8 additional commands via Command Buttons. Configurable WiFi packet interval. Supports a number of micro controllers – requires WiFi module/capabilities. Sample Arduino

Chilean Drinkbot Pees out your Drink

  Not sure why so many cultures have funny characters with big penises but it looks like Chile also follows this tradition. Nathan Pahucki and Pablo Castro made a neat looking drink bot that has a Indio Pícaro doll that will pee out your drink order. If a doll penis offends you please skip the video below… Via: Make “The user chooses their drink from a tablet which is connected to a
