Specially created glass material of the lamp filters out the harmful 185 nm ozone building rays Inside protective covering guarantees practically constant UV output throughout the entire life span of the UV lamp. A Warning sign printed on the tube signifies that the lamp is designed to generate U...
So, if the required maximum LED current is 300 mA, then you can select and adjust the value of the CY to ensure that it never allows the input current to exceed the 300 mA. But if the CY capacitor itself can control the current for the LEDs, then why do we need the BJT current c...
It is. Your lips go through the changes in weather, just like any part of your skin that is exposed to different climates. There is dead skin cell build up on your lips causing them to be dry and flaky often times when they should not be. Use this lip scrub to rid yourself of chap...
The idea for this bot came from the bookRobotics: Discover the Science and Technology of the Future. The specific project that motivated this activity was the Art-Making Vibrobot on pages 24 to 26, though I modified the supplies considerably and the technique slightly. Basically, this little “...
The diagram shows a 110 V version which can be easily modified into 230 volt model through simple alterations. The following illustrations clearly explains how to build a homemade electronic 40 watt electronic fluorescent ballast circuit at home using ordinary parts. ...
In this post I have explained how to make a simple windmill generator circuit which can be used for charging batteries, or for operating any desired
In this post I have investigated 4 simple 220V Mains Uninterruptible power supply (UPS) designs using 12V battery, which can be understood and constructed by
However, I had this idea lingering on for quite some time, though I confess its not unique or new... controlling devices using DTMF codes. Ever since Cellphones have taken the front seats, push button land line phones have become vogue and I had been contemplating powering up one of them...
The external negative-pressure-induced air nozzle is designed with a diffusion tube cone angle of 14°, and given the diffusion tube outlet diameter, the diffusion tube length Ld is determined by the results of the laboratory tests in this project and by referring to the literature [37]: Ld...
