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.,...Tags: POV

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...Tags: POV, RGB LED, TL-WR703N, WiFi

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...Tags: development board, PIC16f, POV

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...Tags: Bus Pirate, demo board, PIC18F2550, POV, Workshop Update

[embed]http://www.youtube.com/watch?feature=player_embedded&v=kPdYpST_yoE[/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...Tags: Arduino, HDD, POV

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...Tags: 7400 competition entry, clock, POV

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...Tags: accelerometer, POV
