Made with six white LED night light without a transformer, making it simple easy-to- Be Careful attention to high voltages are present Circuit Thanks to our brother Murat BAYGIN primarily a very nice application Incandescent or fluorescent light bulb (energy saving bulbs) 9-11W energy spend night lights made of ultra-bright LED night light that is…
Billiards Counter Circuit Even if a counter circuit project is not implemented with the application circuit and detailed information, the information is very valuable. Thanks to the contributors BILLIARD COUNTER In billiard halls, pool players use counters to write down the numbers they receive. The old-style counters were mechanical counters with a hand-turned cardboard display.…
220 volts AC mains voltage and low current LEDs can operate with a simple circuit CAUTION Be careful is working with high voltage capacitor circuit connections Beware + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles. low material cost quite a simple…
Joking can be used as a fun tool, a simple TV remote control is preventing circuit Integrated circuit made with NE555 Timer. Tv Remote Jammer 10k potentiometer on the circuit to adjust the controls are doing http://www.instructables.com/id/TV-Remote-Jammer!/
Let’s do a bit of fun with visual circuits have a few sample pictures circuit in an electronic circuit Dice button produces a different number in each edition. LEDs made with this type of circuit is always ready attracted attention places that sell kits to do is have some sort of .10 5 from me…
Modern White Led Lamps made with your car 🙂 do what your own Lamp I often see white LED flashlight Lcd quite common in various lighting systems compared to prices now dropped the first time in your car warning signal, you can use instead of the internal lamp makes a change Car White Led Lights…
With this circuit, Control devices (tv, vcd, dvd etc.). Different from long distances or from the control room can I will send signals that control circuit (IR Extender) reaches circuit receives signals copies 🙂 and connected to the output of other devices with infrared LED controls Remote Extender Circuit files:
GSM band RF detector circuit for detecting the signals based on the LM358 circuit in an electromagnetic field in the coil when there is a small voltage intentionally induced. Coils connected to the ends of the dipole antenna and RF signal detected from a distance it is arranged for GSM Cell Phone Detector Circuit
LPT port of your computer using the simple and cheap 🙂 You can control various devices such as three circuits have one ULN2803 Used a few passive components easily with the application can be made, but not isolated, the other two is enabled LPT Port from the isolated state opto Kubla made with 24 volts…
