Test your radar detector or laser jammer with this traffic enforcement LIDAR gun simulator

Picture of Test your radar detector or laser jammer with this traffic enforcement LIDAR gun simulator
This LIDAR gun simulator mimics eleven different traffic enforcement LIDAR guns.  Each Lidar
gun operates at 904nM wavelength with short pulse bursts, some guns operate 100 pulses per second, some guns at 238 pulses per second, etc.  The Laser Atlanta LIDAR guns offers a special stealth mode" to defeat early laser jammers by hiding some of the pulses and confusing their detection circuit.  This simulator can reproduce the "stealth mode" to see if your equipment
is vulnerable.  Only radar detectors that detect LIDAR threats are useful for testing, as this
only transmits light not radar.

The following is a list of LIDAR guns it can simulate:
Jenoptik Laveg
Jenoptik LaserPatrol
Kustom Prolaser 1
Kustom Prolaser 2   
Kustom Prolaser 3
Kustom ProLite
Laser Atlanta
Stalker LZ-1
Ultralyte 100/200 LR Revision 1
Ultralyte 100/200 LR Revision 2
Ultralyte Non-LR

Parts required:
16x2 LCD (HD44780 compatible)
(purchased on ebay for $7.50)  It helps to search as 1602 LCD.

940nM LED (close enough to 904nM) 1.5V voltage, 60mA continous
(purchased on ebay for $2.99 for ten)

Arduino board with 3.3V power available
(purchased on ebay for $21.59 Duino 328)

90 ohm resistor (or larger)
10K ohm resistor
10K ohm potentiometer

Step 1: Schematics, LCD

Picture of Schematics, LCD
The schematics are broken into four segments.  I suggest wiring the LCD first and make sure that works before continuing on, as this makes troubleshooting much easier.

Step 2: Schematic

Next wire up the 10K ohm Potentiometer, one lead goes to ground, the other lead to AREF (+5V), and the middle lead (selector) to analog pin 0 on the arduino.  This pot will allow you to make your selection of twelve lidar guns -- one of them is the same gun but with stealth mode activated.

Step 3: Schematic LED

Next wire in your 904nM LED.  Take note that one lead is shorter, this lead must go to ground.  The other longer lead goes to the 90 ohm resistor.  And finally the last lead of the resistor goes to arduino digital output pin 13.

I also simplified the sketch and had it running constantly, routed through my Oscilloscope. You Tube Video Paste into a tab and remove the gap. https ://

Great project Instructions and 'useeful' too. The output from chip is a bit low 40-50mAmp I read & wouldn't drive my LED array, so I added a TIP31A Transisitor in the common way (but new to me) now it has a stonking output as I run it from 12Volts. Does anyone know how to modify program me so I to lock it on 'Fire' all the time Please? mine only fires when resets pressed, then for just 1-2 Seconds..

Wow! This is really cool. Speeding tickets are a right pain in the rear. A lot of people think that a radar detector will help them see the police coming and thereby keep away from a ticket. It might, but there are a few things to find out first. Read more here..
 First comment! pretty good. But there is no way to make a LIDAR jammer.

But if you notice he aims right at the light on the car, which will mess it up if you aim at it, but you are not supposed to aim like that!
I see that you don't know about how LIDAR operates. It will reflect of any reflectable surface, especially license plates and headlights. That is why there is a substance called VEIL, so it decreases LIDAR reflection of all glossy surfaces.

The police officer will aim to your headlight when you don't have front LP, cause it's the most reflective surface.

There are more videos on youtube, or you may google using laser jammer video as keyword.

This is indeed pretty cool.  The giant switch statement is ripe for factoring, though.
