Inductance Meter Electronics DIY This is inductance meter I built using 74HC14 IC. Initially I used a DMM as the display device, but on a whim I tried hooking up a moving coil meter. To my surprise, it actually worked just fine, 1K in series was sufficient to allow a useful calibration and didn't overload the drive capabilities of the last gate in the package. I calibrated my unit for 0 100 uH, as this is the range I am ... Multimeter A multimeter is the combination of a DC voltmeter, AC voltmeter, ammeter, and ohmmeter.An un amplified analog multimeter combines a meter movement, range resistors and switches; VTVMs are amplified analog meters and contain active circuitry. 1W Long Range FM Transmitter Electronics DIY Long range, very stable, harmonic free, FM transmitter circuit which can be used for FM frequencies between 88 and 108 MHz. With good antenna transmitter can cover 5km range. It has a very stable oscillator because it uses LM7809 voltage regulator which is a 9V stabilized power supply for T1 transistor. Frequency adjustment is achieved by using the 10K linear potentiometer.

A cds cell meter is very simple as well if you have a source for cds cells. descrete audio amp, function generator, AC line current ... 3 Transistor Audio Amp (50 milliwatt) Here is a little audio amplifier similar to what you might find in a small transistor radio. The input stage is biased so that the supply voltage is divided equally across the two complimentary output transistors which are slightly biased in conduction by the diodes between the bases. Equivalent Series Resistance Meter Ludens An Equivalent Series Resistance Meter Electrolytic capacitors are by far the electronic parts that suffer aging soonest. If you have any electronic equipment that over the years has degraded its performance, developed quirks, sometimes ending in complete failure, the chances are good that one or more electrolytic capacitors inside it have degraded, causing the problem.

G0SNO's original article was in Rad (RSGB) April 1993, page 74. 5 Transistor ESR Meter Design Page 1 EEVblog Hi Forum Members, There seem to be as many ESR meter designs as people who use them. I have decided to share my ESR meter design with the group. Strictly speaking this ESR meter does not measure ESR, it measures the impedance of the capacitor under test at 100kHz. MOSFET testing 4QD TEC MOSFET testing. Page Contents A Simple test; A better test; Dead MOSFETs; Suitable Meters. A Simple test. Properly testing a MOSFET requires a lot of expensive test gear, but if you have a suitable digital multimeter you can do a pretty accurate go no go test which will fail very nearly all dud MOSFETs.
