 Regulated DC power supply variable output 0-60V 1A

Friday, December 7th, 2012

This 0-60V variable voltage regulator power supply circuit is designed to supply the output voltage to zero volt, without a transformer with a secondary winding two coils. We can use the well-known IC is LM723. Or if you want to pressure is higher, use a number L146. Although is known less. But enough buy them. […]


 Triangle wave generator circuit with cmos inverter IC

Thursday, December 6th, 2012

This is a very Function Generater project. can be used Triangle and Squarewave Generator. The main parts are CD40106 popular CMOS IC and a normal transistor is BC547 or NPN type such as : BC549 , 2N3094, 2SC1815, OR an Old number 2SC458 . VR1 For Control frequency Output. S3 to Seclector High = 1kHz-10kHz, […]


 DIY infrared remote extender circuits

Thursday, November 29th, 2012

      We use the DIY infrared remote extender circuits to control the satellite receiver from any room in the house.With a single receiver.Save money not having to buy additional equipment.       Now the satellite receiver are steadily increased popularity. If you are one of those. And you want to Watch the favorites and control it. From every […]


 Simple preamplifier circuits by transistors

Wednesday, November 21st, 2012

If we want good quality sound system,the first thing to consider is that a good pre-amp. Some people say that’s not necessary. But when the low-level audio source. We may need to adjust the sound too high will cause distortion. so should have the preamplifier to amplify a signal up before to the our power […]


 Cheap microcontroller training package by 68HC705

Friday, November 16th, 2012

The microcontroller IC is a device that looks like a common IC. But inside it, the virtual a miniature computer. This device can be used instead of transistors and IC older those. 40 years ago Electronics fields used the transistors and ICs were equipment important the various circuit assemblie. but current dividend may become a […]
