This is a simple capacitance meter which can measure capacitance value easy. There are some measurement methods for capacitance, at one time the capacitance was measured with a impedance bridge or a dip meter. Recently typical capacitance meters can measure capacitance and some additional characteristics from current vector by applying AC voltage to the Cx.

In early 2005, NEC launched small pin count microcontrollers like PIC/AVR based on 78K0S architecture. The 78K architecture has a register set similar to i8085 and additional bit operation instructions. It can be saied that a stale architecture but the memory space is plain compared to PIC/AVR. There are various devices with application specific peripherals [...]
This is a simple circuit to connect your VGA graphics card to your TV. The advantage of using RGB over S-Video is superior contrast and clarity. The schematic of this circuit is taken from Tomi Engdahl’s site. The circuit basically XORs together your horizontal and vertical synchronization signals to create a composite sync output, and [...]
This is a simple circuit which can detect when you touch a sensor connected to one of the sensor inputs. It can be used to add a touch switch to your computer for example. It uses an AVR micro controller, the AT90S2313.

This is simple thermometer with just few components.
The brain is PIC16F84A and sensor is DS18B20. Range of sensor is -55 to 125°C is possible if ONLY the sensor is in that area not the whole device!

Google Buzz is a new way to start conversations about the things you find interesting. It’s built right into Gmail, so you don’t have to peck out an entirely new set of friends from scratch — it just works. So now you can follow TehnikService on Google Buzz you can find my profile here.
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 [...]
