STM32F103 C8T6 PWM Timer and NE555 redundancy Part 002

Gareth's picture

Latest iteration of the Neon supply 170 - 240 Volt generator.

The original circuit sported a "NE555" to drive the "Fly-Back" inductor N-Channel MOSFET, then after a hour sitting in its cosy socket (and an elvish brainwave later) it has been made redundant in preference to some"PWM Code..."


STM32F103 C8T6 3.3V meets 170Volt Neons. ... Part 001

Over the last few months these "Coloured Neon lamp indicators" have been popping up on the matrix, so I could not resit...well who could not resist mixing 3.3volt logic with 170volt.

They come in a variety of colours "Green","Blue" and "Orange" , the glow intensity is good even in daylight.


Taking the "Blue-Pill" aka STM32F103 C8T6 ... Part 000

The MCU you see above is know as the "Blue-Pill" , it belongs to the STM32 family.

To put it in simple terms.... its a bit like an Arduino on steroids.

PSH's InMoov

I just purchased my first 3D printer about 2+ months ago as a COVID stay sane self-isolation distraction. Recently I discovered InMoov and thought that would be a good project to occupy my stay at home time with.  I have worked with Arduinos and Rasp PIs and thought this would be engaging on many different levels. 

I started documenting my project here on instagram: https://www.instagram.com/phodara/

I have a background in the arts and in I.T.
