Here’s one you don’t see often. Matseng built a free USB POV Toy PCB. These almost never get built due to the challenging QFN chip. The POV Toy is a hand-held persistence of vision toy that can be updated over USB. Check out our workshop video about the latest developments on this project. If you […]
Today’s model is the USB POV Toy. It’s a hand-held persistence of vision toy, that is can be updated over USB. Check out our workshop video about the latest developments on this project. Want to make 3D renderings of your own projects? Here’s our tutorial on how to build 3D models from Cadsoft Eagle board […]
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 overview of the POV Toy project. Displays pattern or words when waved in the air […]
A box of PCBs just arrived from Seeed Studio’s Fusion PCB service. This batch includes: Bus Blaster v2.6 with over voltage protection and series resistors on the JTAG pins Dangerous DSO v1.a with a few minor fixes USB POV Toy v1.a with X/Y/Z axis markers, this will be the production PCB (some day) AlteraMAX3000A CPLD […]
The internet situation pre-Maker Faire Bay Area has been pretty bad. Worse than bad. Today we’re in the conference hotel though, and there’s wired and wireless internet aplenty. If you’re going to Maker Faire please stop by the Seeed Studio booth and say hi, we’re right next to the central Maker stage in the main […]
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 wave the POV Toy back […]
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 Bus Pirate using I2C or […]
A box of PCBs just arrived from Seeed Studio’s Fusion PCB service. This batch includes: Bus Pirate v4 USB POV Toy Through-hole IR Toy PIC USB LCD backpack version We’ll be flinging lead today, watch for prototype updates later.
