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 … Read more
After more than a year of off and on development, there’s finally a working firmware for the USB Persistence of Vision Toy. With a bit more tweaking we’ll be ready to release the code. This week’s workshop video is an … Read more
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 … Read more
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 … Read more
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. … Read more
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 … Read more
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 … Read more
