App note: Safety considerations and layout recommendations for digital isolators

Sunday, April 23rd, 2017

Application note from Silicon Labs about end user safety against high voltage shock that are designed together with digital isolators. Link here (PDF) This application note details the creepage and clearance requirements of an isolator type component, such as a digital isolator, used to provide protection from electric shock. It...

WORKSHOP VIDEO #39: Magnificent Nixie tube thing

Thursday, September 13th, 2012

[embed][embed] This week we try out the IN12 Nixie tube blocks we've been working on. They'll be on display in the new workshop studio and at Maker Faire New York. We also light up a mini VFD we scored in Akihabara in Tokyo last year. Sorry about the poor lighting,...

High-voltage arcs using a flyback transformer from a monitor

Friday, January 20th, 2012

Hak8or uploaded a gallery of high voltage arc pictures. The setup was salvaged from an old CRT monitor. He suspects the flyback transformer produces around 30 kV. I found some old pictures of me playing around with a flyback, and I wanted to test out this awesome gallery thing I...

Let the sparks fly with flyback transformers

Saturday, September 24th, 2011

Flyback transformers are used to drive the large odd shaped coils surround the neck of CRTs in TVs and computer monitors. They operate in the 15 to 150 kHz range, and can be used to generate high voltages! Uzzors2k decided to experiment with generating voltages high enough to produce arcs,...

Bus Pirate high voltage supply with only 6 parts

Friday, December 4th, 2009

We used the Bus Pirate and 6 common components to multiply 5volts to over 120volts with a boost converter, a type of switched-mode power supply. Similar circuits are commonly used to power 180volt nixie tubes from low voltage power supplies. This circuit is a simple way to build your first...

Bus Pirate high voltage power supply

Sunday, November 22nd, 2009

The crew at Robots and Dinosaurs prototyped a high voltage power supply for a geiger counter tube using the Bus Pirate pulse-width modulator. They were able to step up 5volts to 800volts+ with a simple boost converter circuit on a bread board. We always like to see new ways to...

  • William: lol I'm happy to waste 3c for each program/debug cycle... but probably not the time spent soldering a new device down to a proto board!...
