Signal generator PWM 1512 module with adjustable pulse sinus 1-1000 Hz, 4-20 mA 2-10 V LCD-WSFG06

Tesla Transformer is a high frequency transformer invented by Nikola Tesla. It works on a resonance principle, so its circuits need to be tuned for best performance. It is used to obtain very high voltages. Tesla's transformer is essentially a simplified version of the Tesla Coil Magnifier, with which Nikola Tesla liked to experiment.

Bike alarm e/123, bike alarm, bike alarm, bike alarm, motorbike alarm and all portable stuff.

A simple alarm on the bike, motorbike and in general all portable stuff. For example, the alarm is fixed to the bike frame and activated after the key is rotated in 15s.

It reacts to movement, so as soon as the bike moves, the siren begins to hum. Turns off the key again.

Bluetooth marketing is a form of advertising when an ad is distributed via Bluetooth technology. It takes advantage of the fact that nowadays most mobile phones and a large number of laptops, tablets and similar devices are equipped with Bluetooth technology.

The ad notification is first uploaded to a Bluetooth unit that automatically searches for a mobile device with active Bluetooth technology and appeals to them with a menu to download value-added content for the customer. This may be a discount coupon , a business card that is directly saved in your phone's contact list , or , for example , an html page . You can read more about the options for the content you are sending below.

Possibility of voltage regulation from 0.6-36V and current up to 5A. The system displays settings for voltage, current, maximum power, maximum time and capacity. Short-circuit protection, impulse current, possibility of charging a lithium battery, tested protection under voltage during charging.

The Tesla Transformer is a high frequency transformer invented by Nikola Tesla. It works on a resonant principle, so its circuits need to be tuned for best performance. It is used to obtain very high voltages. Tesla's transformer is essentially a simplified version of the Tesla Coil Magnifier, with which Nikola Tesla likes to experiment.

The transformer is made up of two ossair coils with different number of threads. The source of the primary high frequency voltage is a muted spark oscillator (on the basis of a spark, powered by e.g. a sparking a spark. From a high-voltage transformer. 

The AS60 / 1522 stereo spectrum analyzer is very rhythmic, accurate, dynamic, has a concise appearance and high accuracy of a music visualizer.
