High Voltage Switch Mode Power Supply for Nixie Tubes
This SMPS boosts low voltage (5-20 volts) to the high voltage needed to drive nixie tubes (170-200 volts). Be warned: even though this small circuit can be operated on batteries/low voltage wall-worts, the output is more than enough to kill you!

1V boost driver for power LEDs
The PR4404 from Prema is a LED driver providing more than 150 mA out of one battery cell and up to 300 mA from two batteries for one to three power LEDs. A hold input allows controlling the LED brightness via a PWM signal or switching the LED from a microcontroller. Several applications and circuits can be found in the comprehensive data sheet on the web (see below). Samples of the PR4404 are available upon request. [via]
