Simple Circuit Detects Current Pulses:  01/06/94 EDN-Design Ideas / (Electronic Circuit diagram added 03/03)  The pulse detector provides a visible indication of positive and negative current pulses. The pulses amplitudes can vary from20 to150 mA. The pulses durations can range from10 to40 msec, and their repetition rate can span40 to180 pulses/minute.

Simple Wireless Radio Data Link:  This is a description of a very simple unit designed and constructed for use as a wireless data connection between two nearby computers. The error rate is excellent over short runs, and the transmission speed means that a useful PPP link can be established between the machines. Which are, of course, running Linux..... (Circuit / schematic design added 6/06)
