LED POV fan update

Monday, July 6th, 2015

Zach writes: I first posted on how to reprogram a "Programmable Message Fan: Model 45 Series" POV fan a few years ago, and the code I posted no longer works with the current versions of the Octave and Arduino software.  The original post still describes how the fan works and...

Mobile POV device uses Parallax Propeller

Saturday, April 27th, 2013

Here's a unique mobile POV device using the Parallax Propeller. Gareth (chiprobot) designed this gadget using the Propeller MCU driving eight UV LEDs, blasting UV light onto a phosphorescent sheet of vinyl. He says the coding utilizes the Propeller's built-in ROM character map, so code size is very small (i.e.,...

BitBltBlade – WiFi controlled POV lightsaber

Tuesday, October 9th, 2012

Madox designed the BitBltBlade, a WiFi controlled POV lightsaber designed to display images in conjunction with long exposure photography. The BitBltBlade uses the hackable TP-Link TL-WR703N router and Kean’s USB Expander board to wirelessly control a strip of RGB LEDs. The concept of operation is that the user would use their...

PIC16F882 development board for workshops

Monday, June 11th, 2012

Here's an Arduino styled PIC16F882 development board built for a university microcontroller noob workshop. A MCP2200 USB-to-Serial IC handles the USB communication, while the board features all the support circuitry required by the PIC, such as the 5v power supply, quartz oscillator, and the ICSP programming header. The board was...

Workshop update May 10th, 2012

Thursday, May 10th, 2012

Work on the POV Toy continues, and it's the subject of the workshop video this week. We might as well give up guessing the subject of the next video, it's whatever is on the bench Thursdays. The firmware is being tweaked and calibrated, and finalized for production. We're thinking about...

Open source HDD POV clock

Wednesday, February 22nd, 2012

[embed][/embed] Jason designed a persistence of vision hard drive clock. He etched numbers on a copper disk and added 8 LEDs below it. Each LED represents a character on the display and blinks when the corresponding digit passes over it. His project is Arduino-based, and the project files can be...

7400 competition entry: Discrete logic POV clock

Wednesday, October 5th, 2011

Matt's entry in the Open 7400 Logic competition: Discrete logic POV clock. This persistence-of-vision clock was built entirely out of discrete logic chips. The design consists of three boards, a LED array and a drive motor. The digit board keeps the time while the display board controls the LEDs. The digit board Every...

uPOV persistence of vision with an accelerometer

Thursday, April 28th, 2011

uPOV is a persistence of vision device with an accelerometer. This is the same concept we're trying for with the USB POV Toy. The problem I had with most of the current POV units is that they required skill to use effectively, timing your swings so that the message only...

Pyro propeller clock POV

Thursday, April 14th, 2011

Chris from PyroElectro writes:After having seen so many propeller clock POV videos on Youtube, but no real description of how they work or how to build your own, I set out to make one and document how it was built. The Pyro Propeller Clock POV design criteria was short and...
