Got my project working pretty nicely with four of the display boards working together.

 

It's so pretty playing Electric Sheep videos.

 

Still got to populate two more boards, figure out why I'm getting a little bit of flicker on bright frames, and build the module to stream the video from a USB flash drive, rather than from my computer. THEN I can get it all framed (and then figure out the best way to get the glass frosted).

A breadboard test of a DC motor controller. It works by PWM (Pulse-Width Modulation), using a TLC3704 comparator chip to generate a variable mark/space ratio square wave. This is then fed to a HUF75337 power MOSFET. There's a 5k pot in a box to control it.

This reads 2 contact pairs and adjusts the PWM duty cycle going to the PT4115.

Microchip's new family of analog-based PWM controllers with integrated synchronous MOSFET drivers offering outstanding transient performance. Microchip's first-ever family of high-speed MOSFETs offers very low FOMs and is packaged in industry-standard 5x6 mm and 3.3x3.3 mm PDFN packages. For more info, visit: www.microchip.com/get/FR79

PWM 651, Lights, conduit & lamp brackets picked out.

The seven segment display is one of the most popular numeric displays used in many microcontroller applications because it’s cheap, robust and reliable. The seven segment actually consists of 8 LED (Light Emitting Diode) and it’s come with various sizes suitable for various numeric display application such as digital clock, counter, thermometer, humidity, etc. For more information please visit www.ermicro.com/blog/?p=844

NOT 'BRUNSWICK GREEN', let's make that clear.

Equipped with sophisticated Enhanced Capture/Compare/PWM (ECCP) peripheral the Microchip PIC18F14K50 microcontroller could produce up to four PWM channel outputs. The enhanced PWM (Pulse Width Modulation) mode in ECCP peripheral is capable to drive the full bridge DC Motor circuit directly both in forward or reverse direction. It also could generate single PWM output on the selectable PIC18F14K50 pins when it configured in pulse steering mode. For more information you could visit www.ermicro.com/blog/?p=1461

The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive, I decided to use the PIC12F683 microcontroller to generate simple and yet fascinating laser light show from a cheap keychain laser pointer.

All of the lights are suppose to be on... When in fact they are to the human eye. I sped up the camera to detect the line refreshing one by one..

Microchip announced an expansion of its 8-bit PIC® microcontroller (MCU) portfolio with the PIC12(L)F157X family, which features multiple 16-bit PWMs with an assortment of analog peripherals and serial communications in an 8-pin package. These MCUs deliver three full-featured 16-bit PWMs with independent timers, for applications where high resolution is needed, such as LED lighting, stepper motors, battery charging and other general-purpose applications.

PWM654 at Peak Rail, 9th April 2017.

readable information. It will be better for us if we could make it display the words not just blinking the LED. Today most modern gadget such as mobile phone and PDA, use LCD (Liquid Crystal Display) for interacting with us. In this project we will learn how to use the 2×16 LCD for displaying the room’s temperature. For more information please visit www.ermicro.com/blog/?p=519

PWM at Mangalore Airport in Victoria. At the 1983 SAAA Fly In and airshow during the Easter Weekend. We flew down from Sydney for the day on Easter Sunday, 4 hours each way, on this wonderful old girl.

A regular location for taking photos at. I cross this point twice on bicycle commuting days.

 

The vehicle's rear lights appears as a dashed line. These are LED rear lights that derive their tail lamp illumination setting via Pulse Width Modulation control (they are turned on/off at a high frequency). The LEDs are operated 'full on' when used as a brake light.

I made the PWM circuit for analog and a digital comparison. However, a board has grown big.

This vid is the MAX6969's PWM emulation test.

The intesity is controlled from the Max6 with the OSC.

ATtiny85 driving a trio of constant current drivers for PWM modulation of a small LED array.

A gap at the bottom allow the elastic toggles to be fitted from within.

Cheap ass way to create an analog signal from digital output. Pulse width modulation from Arduino used to control the brightness of the led.

This is a full size mockup I put together to test some concepts for my LED array project. There are 16 RGB LEDs spaced about 2.25 inches apart, with scored and folded cardboard light separators. The final array will have 24 of these rows, with the same minimal spacing between all pixels (no 3/4 inch border). The LEDs are PWM controlled to any of 4096 brightness levels per color.

This triangle wave is the residual PWM signal (originally a square wave) after filtering through a simple RC network. The resistor is 1kΩ and the capacitor is 68nF. Amplitude of the 31.25kHz signal is about 0.6V. This seems a bit much to me, so I propose to try a more sophisticated active filter circuit. The scope is a rather beaten-up Philips PM3335.

 

UPDATE: This is the type of filter that I'm thinking of:
