Lightning Detector Circuit and schematic This Do-it-yourself lightning detector circuit can be a especially sensitive static electricity detector which can supply an early warning of approaching storms from inter-cloud discharge properly prior to an earth-to-sky return strike takes location. An aerial (antenna) formed of the brief duration of wire detects storms inside a two mile [...]
Broadband Random Noise Generator Circuit This circuit is normally necessary in testing any sort of electronic methods for example filter, audio, or RF communication. The circuit introduced right here generates an RMS amplitude regulated noise source with selectable bandwidth. This circuit is work depending on op amp. This will be the figure with the circuit. [...]
The simplest of all motor controllers (besides a straight on/off switch) is the contactor controller. I designed this contactor controller for use in my electric scooter project. It is based around three 12V relays, two 12V batteries, two switches and of course a motor. Having no silicon to “fry”, it is quite reliable and robust. [...]
This simple counter can be used to count pulses, as the basis for a customer counter (like you see at the doors of some stores), or for anything else that may be counted. The circuit accepts any TTL compatible logic signal, and can be expanded easily (see Notes). Counter 7 Segment Schematic: 7 Segment Display [...]
This 6V6 amp was built following the push-pull (PP) EL84 / 6V6 Dynaco A-410 output transformer schematic. There are a few minor deviations from the original schematics. Instead of Dynaco transformers, Hammond 1608A audio output transformers and a Hammond 272HX power transformer were used. The EL84 / 6V6 PP Dynaco A-410 output transformer schematic showed [...]
RC5 is not suitable as a barrier to race out to whoever is the winner. Two or more RC5 channel interfere with each other and the protocol itself also takes time for the transfer. If more than one car with RC5 transmitter arrive close together, it can well be the first and the second triggers [...]
You might have seen many videos around you tube showing off crazy LED cubes, forming 3-D structures etc. But haven’t find anything that explains how this is being done. Well searching over internet i found this great project made using a PIC 16F688 microcontroller used to control a 5x5x5 LED matrix cube.
