1. Simple Continuity Tester Fits into Shirt Pocket
   Circuits Measurement Central Semiconductor 2N5087 2N5089
   This Design Idea describes a handy continuity tester with two modes of operation: It may sound if it detects continuity between its two probes, or it may sound when it detects no continuity. The second option permits testing for intermittent cable ...

4. Improved laser-diode-clamp circuit protects against overvoltages
   Circuits Light Central Semiconductor PN4391
   James Zannis EDN Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply voltage, thus protecting it ...
