Reloj amanecer

La necesidad de realizar este proyecto nace por el crudo frío de invierno y las pocas ganas que dan de levantarse tan temprano para ir a la esclavitud legalizada el trabajo, muchos de nosotros quizás nos levantamos con un lindo reloj que suena tan tan feo que varias veces tenemos que cambiar de reloj Otros quizás usen su celular, que nadie sabe porque, algunas veces no lo escuchamos, no se uds pero mi vista no está al 100% apenas abrí los ojos y me cuesta bastante darle al bendito botón AP.......

75 Meter SSB Transceiver

Here's 75 Meter QRP SSB Transceiver. In general, the transceiver switches the 4-element 1500 ohm xtal BPF ends between the inputs and outputs of the two SA602s to reverse the signal flow for R/T operation. Since no IF amplifier is used in the design, 20 dB of additional receiver gain is produced by the 2N2222 receiver RF amplifier, while automatic gain control (AGC) is produced by the peak DC swing of the LM386 output passed through a rectifier and filtered by a capacitor and fed to the gate of .......

Lap Timer Part 5 - Buzzer, External Audio and Some Builds

The latest version of the lap timer includes two new features -1) External Audio - There is now an option to use a very simple amplifier circuit which is small enough to fit inside most project boxes. This will give you a lot more volume when you are using the system outdoors. 2) Countdown - With countdown switched on, the lap timer will beep to count down the last few seconds of the current lap time - it adds a little extra pressure - to beat the lap you have to beat the beeps. For previous ste.......

Cockroft-Walton voltage multiplier.

Cockroft-Walton voltage multiplier (CW multiplier) is another type of voltage multiplier that is widely used apart from Marx generator discussed before. It was initially used by scientists John Cockroft and Ernest Walton to perform atom splitting experiment, which earned them the Nobel Prize in Physics in 1951. I built a simple battery-powered CW multiplier just to get 2mm spark, which enough to lit up a match or a cigarette lighter. As I ve explained long ago, the output from the 555 inverter m.......

Multitone Alarm Sound Generator

Sound Generator: Multitone alarm circuit diagramHere the Multitone Alarm sound generator. This kind of multitone alarm is useful for security alarms, reverse horns, and so on. It generates five various sound tones and is also considerably more ear-catching when compared to a single-tone alarm. The circuit is constructed close to well-known CMOS oscillator-cum-divider IC 4060 and small audio amplifier LM386. IC 40.......

Experiment 12 (Chapter 12) -

Preamp and poweramp. . . both are found in the simple circuit for Experiment 12. I actually had an LM386 in my collection of parts, but it had a mangled pin. Thankfully this is a fairly common component, and Radio Shack sells them for $2. 00. . . so no waiting. The experiment does explain how to bump up the gain from the basic 20:1 to 200:1, but I'm going to stay with the def.......

How to build Multitone Siren - circuit diagram

This multi-tone siren is useful for burglar alarms, reverse horns, etc. It produces five different audio tones and is much more ear-catching than a single-tone siren. The circuit is built around popular CMOS oscillator-cum-divider IC 4060 and small audio amplifier LM386. IC 4060 is used as the mult-itone generator. A 100µH inductor is used at the input of IC 4060. So it oscillates within the range of about 5MHz RF. IC 4060 itself divides RF signals into AF and ultrasonic ranges. Audio signals.......
