I am deeply sorry that this is happening to you. As it is very emotional, being violated, I would offer some options based on your
statement;The police can't help. No matter where I move my car, it still happens, it began when parking enforcement said I had to move my car, and I moved it to another block, and the damage began. I moved the car to other blocks and returned it to my own block, and the damage continues.
If your vehicle is being violated, in a neighborhood where no one else is having their cars destroyed, says something about your
neighbors. This would suggest that your quest for justice will be a solitary one. If your neighbors had the same problem, the police
would probably be more inclined for neighborhood patrols.
Options I could recommend would be;
1> cameras in the vehicle, or imbedded near the tires for taking pictures of the violators.
2> shields on the tires after you park the vehicle.
3> investment of an alarm system on the vehicle
4> build a temporary or small garage to house the vehicle itself. (anyone going in this space will definitely have their picture taken!)
Harbor Freight has small, cheap car storage "sheds" for vehicles.)
The police have a duty to protect you, as they get paid by the public to protect life and property.
Physical cameras present a deterent, even if they do not record anything. If nobody still helps, you could record the violators
and put them on facebook. Social media may acquire the attention you may need
. I do not suggest these actions lightly,
and please take care in the defenses that you employ. I will pray for you.
First let me explain, though my tires have been repeatedly slashed, my headlight smashed, my car damaged repeatedly for the past five months, we are not talking about vandalism.
What we are talking about is a campaign of violence and attempted terror that is being waged against me. I'm a veteran, and that's why I use the phrase "attempted campaign of terror", because the "terror" part isn't gonna work. The damage to my car, though, that continues to happen. The police can't help. No matter where I move my car, it still happens, it began when parking enforcement said I had to move my car, and I moved it to another block, and the damage began. I moved the car to other blocks and returned it to my own block, and the damage continues.
Before anyone feels sorry for me, I'm a US Army veteran, and I've dealt with many bad members of the human race throughout my life.
The reason I am here is because I've been dreaming up counter measures to prevent this asshole (can I say that?) from continuing to damage my vehicle.
I'm not a robotics expert, I know only the basics about electrics and less about electronics. I built my car, I wired my car, it's from the 1960's.
I'm here to listen to any ideas any of you may have for me, if you are like me, you like to dream up solutions to problems. I believe the members on this forum are by comparison brilliant and truly enjoy a challenge!
Here are a few of my ideas:
Surround the car with a two foot wide matt so when a person steps onto it, it activates an alarm, an old style 1950's burglar alarm type bell because they are painfully loud. My problem with this idea is I have not yet devised a way to provide the matt with a switch, switches that are all over the matting, no matter where he steps on the matt.
For example, while in the Army we were taught a simple style of switch, an old paper matchbook, foil, and a thumbtack. The tack is placed between the covers of the matchbook, and this placed under a carpet, so when a person steps onto the matchbook, the tack drives through the paper hitting the foil and completing a circuit.
In the case of my matt, I need it so ANYWHERE on the matt where he steps will activate the switch, and the moment he steps off, the switch goes to the "OFF" position.
I considered motion sensors but then the very loud alarm will go off every time a person walks past the car, or another car passes, and late at night, this will not make me any friends among the neighbors. Motion sensors cannot be limited to within on foot of the car, or maybe they can and I don't know about them? I could not find any.
I have considered making my own stun gun type set ups for each wheel well on my car, but I don't like this idea because an innocent kid may be retrieving a baseball and get zapped if the ball rolls to a stop by my tire and he goes to pick it up.
LET ME BE CLEAR, I AM NOT LOOKING FOR ILLEGAL BOOBY TRAPS!!
I've spoken to the police already and booby traps are illegal. I'm dreaming up counter measures that will dissuade this criminal from going near my car ever again.
I did install a "motion sensing" light in the inside of the passenger compartment, but I learned that motion sensors, at least this one, does NOT work through glass! This also precludes the use of motion sensing dash cameras.
I thought about building an apparatus that sits INSIDE the car, that turns on when a person approaches the car, an apparatus on a swivel that rotates 360 degrees in order to follow somebody who is circling the car, and on this apparatus I may mount a PHONY, A FAKE shotgun.
I have considered installing a large Tesla coil inside the car that when activates when anybody approaches the car, and the electric sparks and bolts of electricity would frighten the person away, but this became too elaborate.
Anyway, I'm curious to read comments of forum members who may ponder my dilemma and who dream up some interesting methods of dealing with this issue.
Thank you very much and I look forward to reading your comments. :-)
Will u buy it for your friends or family ?

I would likt to connect a lazer range finder to a linear actuator, and be able to prest the position/distance. IE if the wall is 60 feet away, you can set it to return to that position when 60 feet distance is achieved again. This would hold true for all distance/position measurements programmed in.
Can this be done? I am sure it is possible, I just dont know where to start. Any help would be greatly apreciated, and thank you for acceptance into your forum.

for a project i have something which is getting me stuck.... so far.
I want to move a servo using a potentiometer, but also i would like to move the servo from the set position by the potmeter with 2 buttons, button A turn left, button B turn right.
In my search for this problem i came to the solution to add up the value pos to val.
But so far this is not working.
This is the test sketch so far:
int potpin = 0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin
#define leftPin 2
#define rightPin 3
int pos = 90;
int delayPeriod = 50; // increasing this slows down the servo movement
myservo.attach(9); // attaches the servo on pin 9 to the servo object
myservo.write(pos); // center the servo
val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023)
val = map(val, 0, 1023, 0, 180); // scale it to use it with the servo (value between 0 and 180)
myservo.write(val); // sets the servo position according to the scaled value
if ((digitalRead(leftPin) == HIGH)&& (val+pos < 180))
else if ((digitalRead(rightPin) == HIGH) && (val+pos > 0))
What am i doing wrong ?

I am currently using the attached 2DW Robot Chassis. 2 geared DC motors are used. I am controlling the motors with an Arduino Leonardo and a motor driver that is essentially identical to Adafruit's Motor Driver v2.0. The issue is that when I supply power to the Arduino via either the USB cable (attached to my laptop) or via the power jack (with a 12V DC supply), the motors do what my code tells them to do. However, when I supply power to the motor shield via the power terminals using either 5, 6, or 8 AA batteries, the motors seem to just do whatever they want. They start by jerking around a little, then run continuously until I disconnect a battery. I have the VIN jumper attached to the shield, and the Arduino power LED says that it is on; it just doesn't seem to be transferring the proper instructions, but it does when I power the Arduino and not the shield. In all cases, the power LED on the shield is on.
Could anyone supply any insight?
