Zen PIN

October 13th, 2009 Comments off

One project that was used for the passcode challenge is called the Zen PIN.  The problem is people who shoulder surf can see your PIN on a keypad system.  So a fun and simple solution is to have the user memorize an algorithm instead of a PIN number.  For a Proof-of-concept the Zen PIN was developed that uses three lights.  The user enters a random PIN and the system then generates an internal random PIN.  It then blinks certain lights to indicate if the next number is greater or less than the one last pressed.  The user follows these visual clues to "unlock" the keypad.  In the PoC this just lights up the green light and plays a "good" tone.

You can take any type of spin with this.  Such as, using multi-colored LED buttons that randomly display a color and the user knows to always press to the left of the "orange" button.  Etc.

Equus Horse Heads

October 8th, 2009 1 comment

Several weeks ago Hive13 volunteered to help out a local theater company known as New Edgecliff Theatre.  They were preparing for the Equus play.  They built several horse heads.  A 3-dimensional and 5 2-dimensional ones.  Our task was to make it so the horse head eyes would glow red via a switch.  Fairly simple except we had approximately 24 hours to do it and radio shack only had a few coin battery holders.  We also needed to make our own defuzers for the eyes.  We made the 3D defuzer with extra vending bubbles and we used a $4 air filter for the rest.  Once we ran out of battery coin holders we hacked a paperclip version which worked great :D

Here are some pics of the finished horse heads

This play has been selling out and has recieved many acculades: [1], [2], [3].  This play is still going on so be sure to catch it!

Project Spotlight: RC Cars

October 7th, 2009 Comments off

We are going to start taking time to share some of the projects that are finished or are at least to a working level.  Both Paul and TP have made some intelligent self guided modded RC cars.  TP has a model with a swivel head that looks around and uses a Neural Network to learn.

TP RC Car

For more information on TP’s design check the wiki.

Paul’s design uses an Arduino and a pair of sensors to do obstacle avoidance and has been rather successful at navigating the space!

Details on Paul’s RC can also be found on the wiki!
