LED Meteor Shower, Rain Tube Circuit. In this post we learn how to design an intriguing LED light effect that generates a collapsing metor shower like appearance. The idea was requetsed by Mr. Pinto Mondal. The Request. Hello sir,I am very grateful of your work. Hp 1320 Firmware Update'>Hp 1320 Firmware Update. Sir I want to make acircuit,which available in the market like 1 or 1. Sir I have made a circuit using bc517 while giving power through pc smps intially LED is shifting from one pin to another and after that light start to began dim and.

Thanks. Pinto Mondal The Design. Ecap Eee Pc' title='Ecap Eee Pc' />As the name suggests, the proposed meteor shower or rain tube LED light circuit imitates a falling meteorite, collapsing in the sky. The effect begins with a sequentially incrementing bar graph type of illumination which suddenly begins collapsing from the rear until its completely OFF, the effect keeps on repeating, quite resembling a chasing and collapsing meteorite in the sky. When connected in groups, the visual experience can be quite a mesmerizing. Note  The collectors of the transistors must be connected with the supply line, while the base diodes across pin3 and pin9.

International Journal of Engineering Research and Applications IJERA is an open access online peer reviewed international journal that publishes research. Supply voltage for the above circuit is 6. V since two LEDs are used on each channel. V supply 4 LEDs can be accommodated on each channel. The supply voltage is connected to the rail associated with pin. IC 4. 01. 7. Pin1. Fn Belgian Mauser Serial Numbers there. IC 4. 01. 7 needs to be connected to the ground line, and not to pin6 as incorrectly shown in the diagram The idea could be achieved through the circuit represented above, using a Johnsons decade counter and a 5. Its basically a LED chaser circuit with a delay effect thats introduced at the base of each LED driver transistor. Convert Ventura Publisher Files Viewer here. The charge stored in the capacitors hold the LED illumination for some moment until shutting them off gradually at the same sequencing rate as these were earlier illuminated. The IC 4. 01. 7 outputs produce a jumping high or shifting logic high across its pin3 to pin9 in response to the clock signals fed at its pin1. Ecap Eee Pc' title='Ecap Eee Pc' />IC 5. The speed of this sequencing can be adjusted and tailored as per preference with the help of the 1. IC 5. 55. The sequencing begins from pin3 of the IC 4. IC, during this course of travel, the LEDs illuminate in a bar graph form, due to the holding charge within the base capacitors of the transistors. By the time the sequence reaches pin9, the capacitor across that bases of the transistors begin losing there holding power as these are discharged sequentially, such that the LEDs too begin shutting from pin3 towards pin9, until all the LED are shut off. However until this process is completed successfully, the IC 5. IC 4. 01. 7 before the LED are able to shut off for evolving the desired meteor shower effect. In order to ensure this, as soon as the sequence reaches pin9, and subsequently to pin1. IC for some moment until the fading or the collapsing effect of the sequence is implemented across the LEDs. The time delay responsible for this must be precisely set by adjusting the base resistor of BC5. IC 4. 01. 7. If you are not interested to include the above explained pin1. LEDs driver stages only up to pin5, and allow the remaining pinouts to be blank, such that the sequencing logic while crossing these blank pins provide the required time delay for the collapsing effect to complete. The idea can also be implemented using 1 watt Le. Eee PC ASUS. Drivers and Download Eee PC 1000HXP. There are 3 download servers available on ASUS Download Site Global, China and P2P. Ds for enabling brighter and more robust meteor shower LED effect. TIP1. 22,and make sure the LEDs are mounted on adequately large heatsinks. In this circuit the timing resistors and capacitors across the transistor bases play an important role for enhancing or degrading the desired meteor shower light effect. The above circuit can be simplified to an extent by implementing the modifications as shown in the following image, although the effect will not be as interesting compared to the original design, the LED meteor shower effect will be still effectively displayed.
