Tiny Isolated Dimmer with Linearly Corrected Output
Dimmers provide a way to reduce the power of resistive elements like heaters and light features by changing the waveform of the voltage applied to them. There are different approaches to the development/implementation of dimmers and there are a lot of how-to guides and projects based on...

Neon Pixels Matrix Display Clock
Pierre @pierremuth.wordpress.com shares his latest project with us. It's a neon lamp dot matrix clock based on INS-1 tubes. He writes: As a big enthusiast of glowing neon, I had to do something with the INS-1 (ИНC-1) tubes. Disclaimer: this project is inefficient in many aspects,...

HV Nixie DC-DC Switching Power Supply using MAX1771
Nixie tubes need about ~180Vdc to light up and thus on most devices, a DC-DC converter is needed. Here we designed a simple DC-DC switching regulator capable of powering most of Nixie tubes. The board accepts 12Vdc input and gives an output of 150-250Vdc. The module is based on the...
