It is my realization of 2006. It is about a Light Show or light game. Here is a presentation by illustration, then the video of the analog-digital electronic product below. A – / Part of the printed circuit reserved for the power supply: rectification and regulation. This is the main electronic assembly stage. Here is the product in a suitable box. Each of the eight channels is fitted with a fuse holder and a short circuit protection fuse.
The power supply is obtained by a 220v / 9 or 12 v AC transformer.
Straightening either by bridge or midpoint. Then, here is a part of the printed circuit before implantation of the components. It is reserved for the driver stage made up of transistors.
Then it is the oscillator and binary counter stage.
The oscillator is realized either by Timer NE555 configured in to stable or another logic circuit such as HEF 4069, 4011,4001,4093 …
Also, a reset of the HEF 4040 binary counter.
It is the turn of the power stage constituted by triacs BTA 16 600C or B in general.
As for this stage, it is intelligently done by a potentiometer and other semi-conductive and discrete components. Switching is made between two states: logical and analog by switches. This switch acts on the basis of a transistor to supply the logic stage in one direction and blocks the current on the stage in the opposite direction. EPROM stage is the core of this innovation. Data saved or written in the EPROM providing several animations such as: 1/8 ignition from right to left or reverse. Come and go. Alternating flashing even odd, four to four etc …
With this last photo, I fully present my printed circuit board. It is intellectual property like other similar creations. To end this edition, I invite you to follow my visual presentation dating back more than ten years.
