Resistor Color Code Calculator Ver 2.4
There are three types of resistor color coding. They have different numbers of color bands and hence provide different information. You can calculate the value of an unknown resistor with this program. (FreeWare)

Yenka PCBsYenka PCBs is an add-on for Yenka Electronics. It takes the 2D circuits you simulate, and converts them automatically into three-dimensional PCB simulations, which can be exported for manufacture.
3D simulation of your PCB
This produces a full 3D simulation of the components on your circuit board. In this simulation, you can interact with switches or [...]
This circuit make possible disconnecting a USB device pernamently connected to the PC motherboard (i.e. card reader in PC case) if isn’t in use. Parts:R1, R2 10 kohm, SMD 1206R3 100 kohm, SMD 1206ZD1 8V2, SOD80 Zener. dioda(6V8 až 18V)T1, T2 BSS138, SOT23, code mark SSSw externí spína? / external switch 4 nebo 6 pin? kolíková [...]
A compact audio powerhouse ideal for guitar or PA work or for use as a general-purpose subwoofer or hifi amplifier. Many people prefer Mosfets because of their legendary ruggedness. Altronics had a Mosfet amplifier module which produced 200W into a 4 Ohm load and so we decided to take a look it. It turned out [...]
This project allows instant start sequentially but a dozen low-voltage lamps 12 V / 60 W, and makes them fade and always sequentially (but slower). This system has been designed to meet the demand of a visitor who wanted ten recessed low voltage spot in a driveway to his house, with the following function: – [...]
This circuit allows switching on a LED when the battery voltage (12V) drops below a certain threshold. The operating system is based on a comparison of tension, which comes in a zener diode. If the supply voltage is 12V and the zener diode is a 10V model (this is the case in the diagram), we [...]
This is a good looking and practical device that can be useful in many areas where countdown timer is needed. This project is based on the PIC16F84A microcontroller. The time range can be adjusted between 1 and 999 seconds. This project has 3 buttons and one of them is named Set Button. In order to [...]
A VU meter is often included in audio equipment to display a signal level in Volume Units; the device is sometimes also called volume indicator (VI). In this project we are building a basic and low cost LED VU Metre circuit . The extent (range) display is -18 dBu to +3 dBu, spread over [...]
Today we have a new category “Projects” and a new electronic project 12 Channel LED Chaser with PIC16F84A.
This project is based on the popular PIC16f84A micro-controller.The heart of this project LED chaser is the PIC16F84A PIC microcontroller.A 4MHz crystal and capacitors C1 and C2 22pf is used for providing clock pulses to the micro-controller. The [...]
