Circuit - NPN-PNP Transistor Tester - Hobby Circuit

I designed this circuit about 30 years ago and still use it from time to time. It is powered from a 3v battery. It makes a tone when the transistor tests good.It can be used to determine device type (NPN or PNP) and the base, collector or emitter transistor pins. It can also test most transistors while still connected to a circuit. ........

Linear Resistance MeterLinear Resistance Meter

Most analogue multimeters are capable of measuring resistance over quite a wide range of values, but are rather inconvenient in use due to the reverse reading scale which is also non-linear. This can also give poor accuracy due to cramping of the scale that occurs at the high value end of each range. This resistance meter has 5 ranges and it has a forward reading linear scale on each range.The full-scale values of the 5 ranges are 1K, 10K, 100K, 1M &10M respectively and the unit is therefore cap.......

Alarm Phone Dialer with MT8880 and PIC 16F84AAlarm Phone Dialer with MT8880 and PIC 16F84A

Just hook this Alarm Phone Dialer up to something you would like to monitor, for example, a high water alarm, low temperature alarm, back window, garage door, etc. When the system is activated it will call a number of programmed numbers to let you know the alarm has been activated.This would be great to get alerts of alarm conditions from your home when you are at work. The microcontroller code is provided on the site........
