Message Wand - The message wand is a good PIC introduction as it
is a simple project yet illustrates many aspects of the PIC usage. Used at
night, the wand is swung around above the head, and to onlookers spells
out a short message in the air using flashing LEDs. It could also be used
with a handle and spun round like a traditional soccer rattle (can you
still get those?) though great care must be taken if you do
this.....(circuit added 04/04/04) |

Picxie 2 8x8 Animated LED Signboard - The firmware supplied in current
sourcecode archive is VERY BASIC. I do intend to draw more patterns. However, a vast
workload coupled with possible emigration has put finished firmware on hold.
Please do go ahead and build this circuit though supplied firmware is fully
functional. You can have hours of fun designing your own patterns and effects!

Read isolated digital signals without power drain - 25-Nov-04 Issue of EDN
Although optocouplers offer designers a straightforward method of establishing
galvanic isolation between circuits that operate at different ground potentials, they
do not provide an ideal approach. An optocoupler draws power from the isolated
circuit, switches relatively slowly, and loses current-transfer ratio as its light
emitter ages..... [Design Idea by Alfredo H Saab and Joseph Neubauer, Maxim Integrated
Products Inc, Sunnyvale, CA] |
