- .. LCD Display How does LC Meter Work? To be able to determine the value of an unknown inductor / capacitor we can use the frequency formula given below. Note that there are three variables that we can work with; f, L and C (f ...Oct 30, 2007
- .. it from singing (yes I tried it without the glue:) Other differences The guy at the parts store didn't have any high-frequency rated electrolytes so I got a stack of generic 1000 uF / 35 V radial ones, but they turned out to be ...Oct 31, 2007
- .. 100 kHz. Note, however that this circuit is NOT a metal detector, but will detect metal wiring if it conducting ac current. Frequency response is from 50 Hz to about 100 kHz gain being rolled off by the 150 p capacitor, the gain of the ...Oct 30, 2007
- .. board you can find the IR-receiver, which in our case is TSOP1738, but you can use any other type of IR-receiver which has frequency of 38 KHz. For output power stage you can use triac TIC206 or TIC216. For loads more than 150W you must ...Nov 2, 2007
- .. Transmitter PIC16F630 is the heart of the transmitter used to send IR command to receiver.It also generate 38 KHz carrier frequency. The CR2016 is 3 V battery which is supply for the circuit. When any key not pressed the CPU work in ...Nov 5, 2007
- .. switch on the remote and wired my 9 volt battery to it. Test it out! You may have to tinker with the 10 k pot to get the frequency right for the device you are targeting. Adjust the pot while the remote is 'on' and test it ...Nov 6, 2007
- .. been reading a lot on how DTMF (Dual Tone Multi Frequency) tones work over the last couple of weeks. I’m sure you’ve noticed that when you press the ...Nov 18, 2007
- Jon Dutra.. an LT1004-1.2 and reducing R1, the reference bias resistor, to 1k. The 510 Ω and 1.1k resistors are required for high frequency stability; they suppress a 1 MHz oscillation. The 1N5400 diode and 4-amp fuse protect the circuit from ...Jun 22, 2023
- .. the value of feedback resistance to more than 499 Ω. Whenever the input voltage is only approximately 0V, the frequency-gain response of IC 1 for an R F value greater than 499 Ω remains flat. An analysis of the ...Nov 26, 2007
- .. Sometimes, system noise or other factors cause the otherwise slowly fluctuating data to jump around. To reduce higher frequency noise, designers often install an analog RC (resistor-capacitor) lowpass filter between the sensor and ...Nov 28, 2007
