The idea of reading temperature via USB is very simple. Construction is reliable, precise and requires few components. Circuit is very simple as there is USB to UART converter IC used.

 
USB to UART conversion is performed via F232RQ chip from FTDI (Future Technology Devices International). Besides ability to convert this chip also can work in [...]

Probably everyone knows what are logical IC’s and how to use them in the design. But if design is more complex, electronics enthusiasts more likely are going to choose microcontrollers as they minimizes the count of external components. But problem is that not everything is possible with microcontrollers. They have many disadvantages when fast response [...]

This filter was designed to filter 1kHz frequency of telemetric signal from environmental noise. Filter itself is very simple built with acceptable electronic parts worldwide. This filter can be used in any circuit because of it’s simplicity.

 
Circuit contains minimal amount of parts including one general purposes NPN transistor with coefficient 50…70 an more. Such filter [...]

After project source code is developed there is always need to flash it to microcontroller. There are few ways to program AVR microcontrollers. Usually we used to flash AVR’s with ISP adapter (or other programmer) that is not always handy especially when designing device for the end user who doesn’t have ISP adapter or doesn’t [...]

Motor torque (momentum) is one of motor ratings which is used to indicate motor rotary force produced on its output shaft. Motor torque rating is usually captured at point when motor is stalled. Torque measurement unit is (Nm) in metric system or (ft lbs) in US system. But principle is the same torque is a [...]

Pulse transformers are little different from regular AC transformers. In AC transformers magnetic flux alternates between negative and positive values in core while in pulse transformers magnetic flux is unipolar. Pulse transformers are used in TV, computer power supplies. If you need to test pulse transformer it may be almost impossible to do this with [...]
