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...

WORKSHOP VIDEO #21: USB POV Toy calibration tests

Thursday, May 10th, 2012

[embed]http://www.youtube.com/watch?v=DK1wBSJh3R0[/embed] Today we play around with the latest USB POV Toy hardware and firmware. The POV Toy is a persistence of vision (not division...) device, but we added some special features. First, a USB connection makes it effortless to upload new patterns. Second, an inexpensive accelerometer actively detects the waving...

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...

USB POV Toy: miniscope v3

Wednesday, November 3rd, 2010

We wanted an easy way to see the accelerometer data from the USB POV Toy. We made a simple firmware that works with the miniscope v3 oscilloscope program. Instead of sending voltage readings, it sends the accelerometer data from one axis. This screenshot shows the change in readings while we...

USB POV Toy: Soldered prototype

Tuesday, November 2nd, 2010

Here's the soldered prototype of the USB POV Toy.  The first power up exploded a backwards tantalum capacitor with an impressive spark, but after that was sorted everything seems to be ok. The tiny MMA7455L accelerometer took a few tries to solder, but now we can access it with the...
