How To Hack an Electronic Road Sign

How many times have you driven by an electronic road sign like one of these?


This is the ADDCO portable sign. Today, you see what is on the inside, and how they are programmed to display important information.

*** WARNING YOU SHOULD NEVER TAMPER WITH THESE SIGNS ***


1. The access panel on the sign is generally protected by a small lock, but often are left unprotected. Upon opening the access panel you can see the display electronics.


2. The black control pad is attached by a curly cord, with a keyboard on the face.


3. Programming is as simple as scrolling down the menu selection to “Instant Text”. Type whatever you want to display, Hit Enter to submit. You can now either throw it up on the sign by selecting “Run w/out save” or you can add more pages to it by selecting “Add page”

Should it ask you for a password. Try “DOTS”, the default password.

In all likelihood, the crew will not have changed the password. However if they did, never fear. Hold “Control” and “Shift” and while holding, enter “DIPY”. This will reset the sign and reset the password to “DOTS” in the process. You’re in!

Dear Anonymous above, Shut The Fucking Fuck up you piece of shit on a toilet bowl. By news, you mean your local news station that anyone out of your town would give less shit about. If I ever found you, I wouldn't fry your balls, because that is unrealistic, instead, I will throw an empty can of soda at you, bitch.

McDonalds doesnt have a special of the day. Also you must be gay to touch another mans balls. Also you are probably too stupid to even be able to hack a sign while having instructions.

Good detail although there are alternate ways to drive the thermistor. Something to note is that the circuit in Figure 2 reduces the dynamic range of the ADC, something that may be of concern if you only have an 8 bit ADC available.
