It is a driver for inner window blinds.
LINK
Assumptions:
The main assumption was automatic covering window after switching on light in a room (after dark). The driver is very universal, what more, it is possible to modify the parameters of the driver operation.
Functions:
controlling both...
It is a design of hygrometer for ultrasound air humidifier. This simple circuit uses a small microcontroller and cheap humidity sensor.
Construction:
The circuit was based on one-sided PCB. It contains a linear stabilizer 5V, multiplexed display, processor Attiny2313, two buttons and a relay...
Described here construction of a universal development kit can be a great alternative for expensive factory development kits which often offer small number of functions or lack basic peripherals.
The most important advantages of the PCB are:
the possibility to connect any microcontroller in...
It is an interesting device – voltage transformer which is commonly used in electroenergetic networks to measure one phase voltage values on medium or high voltage lines.
Such voltage transformer works identically as an ordinary transformer. Voltage from line WN passes to the primary winding...
This clock with additional functions of date and thermometer is built on six Nixie tubes.
Assumptions:
use of AVR microcontroller
one-sided PCB
possibility to maintain timing (RTC apply)
display multiplexing (one 74141 apply – reducing the costs)
date display
separate PCB for tubes and...
This power supply is an useful item in every electronic workshop. It can be used to test circuits. The power supply provides 15V/1.5A what can be great opportunity when using computer for tests is not enough for you.
Construction consists of five modules:
the power supply
voltage switching...
This article is to describe how to assemble Webasto Thermo top Z from Rover 75 in Ford Orion 1,8D 1992. Due to the fact that it is a really old car and sometimes it is difficult to start it in the winter, when you are an owner of such a vehicle – this text is for you.
Assembly:
First of all...
Presented here design is a home made smoke generator.
List of elements:
500W stove
two 150W stoves
tank
pump from the washers
driver
thermocouple
One of the main assumptions of this project was to create a cheap useful machine for generating smoke. Inside the stove there is a spiral...
It is a design of electronic Christmas tree. It consists of 72 transparent SMD LEDs in the following colors: green, red and blue. Diodes are connected in series by 3 diodes, and powered by +12V. They are turned on by transistors NPN-SMD in housing SOT323 (it is smaller than SOT23). The...
This system receives MIDI signal and controls 16 floppy drives. MIDI input is carried out via a serial port. This solution can be improved by implementation of a current loop through which you can select whether the signal is to be taken from the real MIDI or from MIDI on RS232.
There are 16...
This camera was designed to be used with Sky-Watcher telescope. Original camera of this type is very expensive and creating your own optical device can give you much fun and let you save a lot of money. It uses electronics and signal cable removed from the Internet camera Creative Model: VF026D...
This movable LED head can be easily done in your workshop. It is based on two drivers AVT395 with modification consisting of the fact that when there is no music, the head stands still. One driver is responsible for up-down head movement and the other – for right-left movement. Light is provided...
It is a simple design of J-pole antenna for short-waves which can be performed even by a beginner. The main assumption of this project was to create the omnidirectional, not directional antenna and thus the construction is specific for this kind of antenna. The main load-bearing element of the...
Described here LCD display can be a part of smart house system which controls the lighting, gates, sensors and other devices. The display has access to the functions through Internet website what makes it a very attractive machine.
Displays of mobile phones from Nokia are made by two...
It is a design of flasher in the form of a bauble. This small decoration looks beautifully when hanged on a Christmas tree.
The circuit consists of a RGB diode and microcontroller PIC12F1822 that directly controls the RGB diode. It is waken up by WDT in a specified time interval. At the moment...
