It was published in the June, 1994 issue of Everyday with Practical Electronics, a popular electronics magazine that is owned by UK publisher Wimborne Publishing, Ltd. The entire kit is available for the cost of £63.95 (what's that, about $100 US?) from END GENERAL## Magenta Electronics 135 Hunter St. Burton-on-Trent Staffs, England DE14 2ST Tel [phone] END TEXT##When this article was published the only source for the programmed microcontroller was Magenta or the author and it was pre-programmed and not modifiable by the user. Due to the generosity of Mark Pauls, we have available his PIC code so not only can you program your own PIC, you can make timing modifications as you like.
