DIY USB password generator » Code and Life

Having done half a dozen V-USB tutorials I decided it’s time to whip up something cool. As USB keyboards were an area untouched, I decided to make a small USB HID keyboard device that types a password stored in EEPROM every time it’s attached. A new password can be generated just by tabbing CAPS LOCK a few times (4 times to start password regeneration and one tab for each password character generated, 10 is the default password length). Below you can see the device in action: The place I work at requires me to change my password every few months so this would be one way to skip remembering a new password altogether (as long as I remember to write it down before regenerating a new one so password can be changed :). What is inside? The device is powered with a simplified version of the hardware I used in my ATtiny85 USB tutorial – I stripped away the LCD, reset pullup and both capacitors. The enclosure was graciously donated by an old 512 MB flash drive. Software Update 2: Indiegogo project

Solid State Tesla Coil A solid state Tesla coil is one of the kinds of Tesla coils available. It has several advantages over the more common spark gap tesla coil. They are less louder than conventional Tesla coils, yet they can still achieve a respectable output. They can also be made to play music through its spark, which is a cool effect. Examples of this trick can be seen by searching for musical tesla coil or singing tesla coil. In the following instructable, I will show you how to make a solid state Tesla coil, as well as several helpful tips and hints that will come handy during its construction. While fiddling with the antenna, I accidentally burnt both of the Mosfets, so bear in mind this design is far from perfect.

Visual Network Threat Level Indicator Network monitoring is very important in todays world. The internet is a scary place. People have taken steps to raise their awareness by installing Intrusion Detection Systems(IDS) such as SNORT. The problem with most of these systems is that upon first installing them they are vigilantly watched. After a week the allure wears off and they are no longer monitored, silently churning away in the depths of the network. By moving the visualization outside of the computer we make it easier to notice, providing the information at a glance and to a larger audience. The Visual Threat Level Indicator (VTLI) requires a network connection and power. A python script is run on the IDS which connects the the Arduino and updates the display.
