Pharmacy signage display 55

 

With this video, I present some LED articles made in my workshop on an experimental basis. Arrows and garland. This garland with which I previously decorated my window.

Once I had saved an idea for another decor, I removed this article. This is my first assembly of LED arrows. In addition a multicolored garland.

The LED wiring is done in sets of seven and powered by a traditional 24 VDC power supply. Everything is done in my workshop.

Let’s see this second video, displays on the window the moving garland with variant animations and in the background a sign for a teleboutique.


As I got into LED display, I had created and produced these and other items on a non-profit basis. I had started my profession around 1985, the first article produced was a play of light with color spot lamps.

Its principle is based on three Triacs controlling the lighting of the lamps by audible frequencies. The device must be connected by conductive cables to a sound amplifier. Low frequency

filters have been produced by discrete components. These are non-polarized capacitors and ohmic resistors and a small isolation transformer placed between these filters and the conductive wire of the signal to be taken from the amplifier. of his.

Afterwards, I opted for an improved creation Well, it’s done independently. A play of light with power supply and micro chip to capture sound waves and activate low pass filters controlling the lighting of the spotlights.

 

After all, everything is abandoned. I would come back more pie for another innovation by way of research. It was successful, but I hesitated to continue this walk. Let’s see the video from below.

This is something special. This a so-called analog and digital realization. So, I conclude this article a little varied but it revolves around the lighting in general.

Previously, before the era of RGB LEDs and other colors, named accustomed to these fragile neon signs and consuming much more energy. The flashers made are triacs. On the other hand, for LEDs consume low electric current and low power.

Carte électronique pour NE 555

 

My printed circuit album.

 

1 /: Printed circuit for NE 555 application  in monostable Date of tracing and development: late 1989 It is for the design and the realization of a timer for domestic lighting that I used the Timer NE 555. Although I gave little importance to this realization, when my customers encounter difficulties with imported electrical equipment, I am forced to be of service.

This image is that of the printed circuit created for the use of two EPROMs of eight bits of data (two bytes in total). Such as 2732,2764, 27318, 27532, 27C1001 and others….

This printed circuit is created for the use of FETMOS CD 4001 and 4011 in astable or multivibrator.

This card is created for the control of spot lamps in two ways: logical, by data saved on EPROM. Analog, by sound waves picked up by microphone and amplified to excite TRIACS. Everything is wired on eight channels.

2 /: RS flip-flop with NPN transistors 1980s This circuit board dates from the late 1980s. It is a NPN transistor assembly. I took the opportunity to produce 220 VAC turn signals. This product was adaptable with the use of high power transformers such as 110 / 220V / 10000V. This product is appreciated by Mr BOYER CEO of an advertising company established in Casablanca since the 1950s. In an interview between the two of us, Mr BOYER testified to it by telling me: It is the only flashing light held strong with a 110v / 10,000 volts 100ma transformer.

Astable with square signal for single or double channel flashing:

3 /: IC for EPROM 2732 and other 28 and 32 pin applications. Early 1990s When I started with ROMs or EPROMs, I had made several eight-channel or lane PCBs, after that I upgraded to a sixteen-channel or lane version as shown next.

4 /: Card for 24-bit display: 3 EPROM Early 2000s Once I was asked for items for display above sixteen lanes I embarked on a new adventure. It is very successful in order to meet the needs of dear customers. Here is the image of a map made in 2006. 5 /: Applications to hef 4011 and 4001 Year 2012 This printed circuit is designed and produced for a public works company in Casablanca. 6 /: HEF 4017 and HEF 4069 applications Early 1990s 7 /: Card for digital and analog animation by spot lamps. Year 2006 8 /: Card for two-byte display (two EPROM 2732 and more) 9 /: Multi vibrators with HEF 4011 and HEF 4001 10 /: Card for HEF 4069 and 74HCT or HC04 flasher
