The lamp is a great thing for the dark, which does not heat up and consumes very little energy, because the power in this case will be from USB. It creates soft and pleasant lighting, and
The voltmeter and ammeter circuits are practically no different from those recommended by the manufacturers of this microcircuit. A feature is compact performance. Voltmeter. The first version of the device
In this article I will talk about one very interesting homemade product. Tube clock in the style of the well-known game "Fallout". Sometimes you wonder what some people are capable of. Fantasy coupled with straight arms
The Arduino NRF24L01 wireless radio module with a built-in 2.4 GHz antenna and power regulator will certainly be interested in those who are keen on designing electronic devices. In particular, this
To make the backlight you will need: - LED strip - batteries - push button switch - wires - double-sided tape or thermal gun - electrical tape - soldering iron and soldering
There is such an interesting thing in the world as the Peltier Element - a thermoelectric converter with a reversible effect. Its device is very simple - it is a plate with many connected pairs of heterogeneous
Creating a microphone for a computer or camera is not at all difficult. But not every microphone can achieve the desired result in a certain situation.For example, because the microphone is elementary
For the manufacture of power supply units for power amplifiers, low-frequency 50 Hz transformers are usually used. They are reliable, do not create RF interference and are relatively simple to manufacture. But there is
This circuit was taken from Radiohobby magazine No. 3 for 1999 and is a step-up voltage converter built on the principle of a blocking generator. Generated by
It all started with the fact that the Cosmos flashlight was bought, working on three finger batteries. He did not work long - refused after five starts. As it turned out, the LED burned out. To limit
