Here’s a handheld POV toy packed into an Altoids tin. The brain of this device is a Parallax SX microcontroller, while it’s powered with two AAA batteries. 7 LEDs provide the POV display that is capable of storing 32 messages. There are 32 message slots — 16 are straight hard coded bitmaps, 16 are text […]

Documentation on the open source USB stack is very close to completion, look for a full announcement next week. The John Doe board from the flux off needs a second revision with more room around […]
WORKSHOP VIDEO #21: USB POV Toy calibration tests
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 motion and syncs the pattern. We […]
Updates from the workshop for May 9th, 2012
The latest POV Toy hardware is finally assembled, and initial testing of the firmware went successfully. We still need to design a calibration routine to get the best results. Pietja’s LGA soldering pictures will be up soon. Work on the open source USB stack demo continues. We found the right linker script for the PIC18F24J50, […]
