IBM’s developer works show you how to make a “persistence of vision” device to spell words in the air with a Basic stamp… – “In this first article on microcontrollers, Erik Zoltan tells you what they are and how they work to your advantage. He presents a few simple examples illustrating how microcontrollers can be used, and gives you a complete implementation of a kinetic glowstick that uses persistence of vision to display images with a flashing row of LEDs.” – Link.

From the MAKE store:
The MiniPOV2 is a persistence-of-vision device that rapidly blinks 8 LEDs on and off so that when waved through the air, an image or message appears to float in front of the viewer.
This kit is an easy-to-build demonstration showing how microcontrollers work. It teaches:
- How to solder
- How to assemble simple kits
- How to program microcontrollers
The kit includes a Microcontroller, sockets, resistors, LEDs, connectors, a battery case and a printed circuit board. Add some basic tools, a PC with a parallel port, and a little programming, and the MiniPOV is ready to blink out your deepest thoughts.
Get one now, at the MAKE store – Link.

Has anyone converted this code for the BS1?
That circuit diagram (schematic) looks wrong; surely the ground pin of the microcontroller (pin 7) should be connected directly to the battery, not via the resistor? As it is, the voltage supplied to the microcontroller will vary according to how many LEDs are turned on.
Here’s the code for basic stamp 1
I wish the pre tag worked properly. :-(
Cut the code out and drop it in your editor. Uncomment the letters
numbers and symbols you need and change the code near the top.
There’s lot of room for improvement here!
IBM seems to have pulled the article bummer Did anyone get a PDF of it?
