I'd run that by a lawyer before trying it out. You can't even do that in Florida. Shooting someone just for trespassing is not the same as "standing your ground".Law changed about 10 years ago we have the right to protect our self if someone is sneaking around in the dark and I shoot them dead it is not a problem 1 less thieve for the legal system to deal with.
YOU must have low crime where you live. Locked doors keep out good people not thieves. Crime keeps getting worse apartments near the house we use to live police were there several times every night. There were shootings there all the time. Lots of houses were getting broken into so we moved to a better neighbor hood. We lived in a better neighbor hood until children graduated from college sold the big house and down sized to a smaller house in a nice neighbor hood but now houses are getting broken into almost every night here. Kids come around after dark break out car windows to see what they can steal. People 2 houses away were broken into and beaten with baseball bats they were in the hospital 2 weeks, police arrested the 2 boys that beat them they spent 30 days in jail now they are out on porbation. People across the street were broken into and several houses near us broken into and 2 cars were stolen. Crime gets worse all the time minimum wage has been $7.35 for 17 years no one can live on that. Drugs get worse people steal to buy drugs. So far people with barking dogs have not been broken into. Some towns crime is worse than others. I caught a girl in my vehicle in Walmart parking lot few weeks before Christmas she was searching the glove box when I opened the door, she jumped out and ran. Our dog is old it is a good watch dog barks at everyone she sees. I would hate to shoot anyone.Do you live in a tent in a park? Then you need batteries for your blinking lights because there is no electricity outlets in the park?
I live in a brick house with locked doors. I do not need blinking lights because thieves do not come here.
That sounds interesting. Which end of the board is the detector? Where does LED & batteries solder on?The idea is the radar boards turn on an LED as people approach. They get close, they see an LED go on - they've been detected. They back off, the LED goes off. They get close again, the LED turns on again. They move to a different spot. The same or a different LED turns on - detected again. They don't know if these are connected to an alarm system, a camera or something else.
The alternative is a bunch of flashing LEDs that flash all the time. Nothing changes if they get close. Don't need a whole lot of brains to figure out nothing happens.
Less than a buck a module, plus an LED and resistor. That's pretty cheap.
Wrongo. They are self-contained motion detectors. As I explained, I have played with them and they will detect a person through a sheetrock wall.I don't think those boards include the radar source. They only detect radar frequencies or leakage from a microwave.
It's pretty simple - details are readily available. Engineering consulting doesn't come cheap.That sounds interesting. Which end of the board is the detector? Where does LED & batteries solder on?
I often take my laptop to McDonald's, buy lunch and work away for a while.Next thing you know, some one will be trying to steal WI-FI from the McDonald's down the street .
1. I ready don't spend time typing this stuff up for my health. As I stated already - I don't know anything additional:I have 2 questions.
1. Can this photo conductive cell be used to tune off this LED flasher during the day then turn on after dark.
2. If LED is removed from a working circuit will the circuit continue to run and us up the batteries?
