TILT – Tiny Ilda La<\/span>ser Tester<\/span><\/p>\n

Lockdown is a pain, there’s no more event a<\/span>nd<\/span> every shop are closed<\/span><\/p>\n

 <\/p>\n

What can<\/span> I do as a project, with al<\/span>l th<\/span>e electronic<\/span> parts lying around in my drawers?<\/span><\/p>\n

\"\"<\/a><\/span><\/p>\n

\u00a0<\/span><\/p>\n

The goal of this mini proje<\/span>ct is to make an autonomous laser tester
\n<\/span><\/p>\n

So I can test all the colors and the scanning of any ILDA lasershow projector.<\/span><\/p>\n

It must be easy to<\/span> build without electrolytic cap<\/span>acitor (only 3 resistor and 3 capacitor references)<\/span><\/p>\n

\"\"<\/a><\/span><\/p>\n

I start by entering the diagram in simulation software<\/span><\/p>\n

\"\"<\/a><\/span><\/p>\n

\u00a0<\/span><\/p>\n

using 555 circuit I make a variable speed oscillator<\/span><\/p>\n

\"\"<\/a><\/span><\/p>\n

\u00a0<\/span><\/p>\n

Then there is a LPF filter then symmetric amplifier.
\n<\/span><\/p>\n

Here’s the frame displayed, a little diagonal line<\/span><\/p>\n

\"\"<\/a><\/span> The project is assembled with usual equipment<\/span>
\nDon’t forget to discharge any static electricity on you<\/span><\/p>\n

\"\"<\/a><\/span><\/p>\n

It’s a printed circuit with 2 layers and metallic holes<\/span>
\nSimulation files, PCB under KiCad and Gerber (click)<\/span><\/a><\/p>\n

\"\"<\/a>If you don’t have 3.5mm resistor you can solder the usual ones vertically (Chinese method)<\/span><\/p>\n

\"\"<\/a>Regulators’ fingerprints are to be reviewed but this is suitable for the moment<\/span><\/p>\n

The 3 potentiometers allow you to adjust the colors (red, green, blue)<\/span>
\nRemember to always start and end use with the colors at minimum setting<\/span><\/p>\n

\"\"<\/a><\/p>\n

The connector is soldered on the edge of the 1.5mm PCB<\/span><\/p>\n

\"\"<\/a>The 4 new alkaline batteries cost me \u20ac 6<\/span>
\nWarning the total voltage is close to 40 Volts<\/span>
\nTo use only 2 batteries it would be necessary to add large electrolytic\u00a0 capacitors and a transistor (bias)<\/span>\"\"<\/a><\/p>\n

The potentiometer adjusts the scanning speed<\/span>
\nThe switch changes between high speed and low speed<\/span>
\nIf the speed is reduced to a minimum then the hardware scan fail security must activate<\/span><\/p>\n

\"\"<\/a>Finally I use anti-static foam insulation with hot glue<\/span><\/p>\n

\"\"<\/a>Here is a portable laser tester for use without audience<\/span><\/p>\n
