Step 5: HOOK UP POWER


Open the hood and locate the car battery. Make sure the power switch on the power inverter is turned off and nothing is plugged into it. Connect the red cable from the power inverter to the positive battery terminal first, and then connect the black cable to the negative battery terminal.

If you are careful about closing the hood you can run the cables through the crack between the hood and car. Otherwise, just leaving the hood popped open can make it look like you are just having car troubles.

Turn on the power switch of the power inverter. Depending on what model you have you should see a green light come on and hear the soft whir of the fan turning on (if something else happens check the alarms listed below). If you have a green light plug in the power cable from the digital projector into the power inverter. Hit the power button on the digital projector. After the projector goes through its warm up cycle and the bulb turns on you will know you are in business. At this point connect your laptop and you are off and bombing.

Tip:
You may want to bring a piece of cardboard to set in front of the projector as you go through the process of booting up and connecting. This is will allow you to see if it is recognizing your laptop, and you will spare your potential audience from having to watch you boot up windows, find your files, and launch your application.

Alarms:
Warning alarms and signals will vary on different models, but the warnings for the Vector brand inverters are as follows:

  • A continuous alarm signals that there is a bad wiring connection. Take this one seriously. One time I tried to ignore it and my inverter starting shooting fire out the back and nearly caught the dashboard of the rental car I was using on fire. Check the connection on the battery to make sure you have a tight connection on both power and ground.
  • A less constant audio alarm is a signal that the voltage of the battery is low.
  • A red light with no audio alarm is a signal that there is too much power being drawn from the inverter. Try plugging in less stuff.

If You Wanted To Be Truly Hardcore, You Could Get Some Four Guage Cable From An Electrical Supply House (You Don't Need That Expensive Ass Amp Power Cable, Its A Little More Flexable, Butt the Stiff Stuff Just Takes A Little Planing And Bending), A Fuse Block And Run The Hot Cable All The Way To Where You Need It Underneath Trim And Carpet. I Would Suggest The Trunk Then You Could Mount The Inverter To The Under Side Of The Rear Deck (By The Speakers).And Run A Short Ground Cable To The Closest Big Bolt. Then Depending On The Type Of Trunk You Have You Could Work Out A Telescoping Mount To Extend It Out Of Your Trunk And Up In The Air To Avoid "Down In Front" Syndrome. My Buddies And I Use To Do This For Movie Night At The Abandoned Drive In Theater (Then Run Sound From The Laptop To The Car Stereo). For A Little More Clandestine Operation You Can Set The Projector On A Tripod In The Back Seat Aiming It Out The Side Window. Message Me For Any Logistical Questions, I'm Bad Ass At Car Mods.

 That literally hurts my eyes to read.

Caping every word is hard to read, and makes me want to tear out my eyes, please don't do it, it's painful to read.
John Smith in reply to Dr. Pugsly Eskobar Esq.Nov 21, 2007. 3:02 PM
Pssst- you're not supposed to capitalize every word, just the ones at the beginning of sentences (they start after one of those dot things- they are called periods).
mrgy05 in reply to John SmithNov 30, 2007. 6:51 AM
Uh yeah, I have seen people do it before, stupid people who don't understand English and how to write / type properly.
zugy in reply to mrgy05Nov 20, 2009. 8:02 AM
I don't understand English properly. I am French and may be stupid too..
ndinitz in reply to zugyMay 9, 2010. 8:11 AM
 Well, you may not understand English properly, but you did manage to capitalize both "English" and "French" so I think you are alright and can stay.

It's A Visual Punch To The Face, And It Sets My Posts Apart From Everyone Else. Have You Seen Anyone Else Do It???
Kasm279 in reply to Dr. Pugsly Eskobar Esq.May 9, 2010. 12:05 PM
Yeah, It's a visual punch that blinds someone. Its annoying, you might get farther if you didn't do it. Most of the time, its noobs that do stuff like that :) 
Azayles in reply to Dr. Pugsly Eskobar Esq.May 9, 2010. 8:44 AM
I've seen lots of people do it. Stupid people. It sets your posts apart because it means people don't want to read them. If that was your aim, then why post in the first place?

It's terrible grammar.You're fired.
Joebob in reply to Dr. Pugsly Eskobar Esq.Feb 20, 2008. 3:40 PM
I have seen others do it on other forums, and those persons are generally dismissed as immature, or of limited intelligence. Do you really want to add this "punch", not to mention making your posts difficult to read?

No Problem John Smith. I Was Just Trying To Add A Few Extra Ideas And Offer My Knowledge Of Car Modification To Anyone Who May Undertake This Project, And Your Right, This Is A Very Good Instructable, While I Had Used A Projector For Movies, But It hadn't Crossed My Mind To Use It In An Urban Art Setting. When I Get My Next Commission Check, I'm Going To Buy A New Projector (My Old One Got Trampled) For Just That Purpose. Do You Have any Suggestions On One That Would Be Good, John Or fi5e??? I Didn't Realize I Was Back In Parochial High School About To Be Rapped On The Knuckles By Sister mrgy05!!!!!! To Elaborate mrgy05; "Uh" , And I Believe Most Intelligent People Would Agree With Me On This, Is Not Proper English, Nor Is The Use Of A Forward Slash A Proper Substitute For The Word "Or". So, When You acquire A Masters In English, Or At Least Attain Perfection In English Composition, You May Then Go Around And Pretend You Are The Grammar Police, Or You Could Actually Post Something That Is Relevant To The Topic Or Try To Use Your Nonexistent Brain Power And Continue An Idea In The Posted Instructable. Until Then Sister, You Can, In The Words Of My Late Great Grandpa, "Shut Up". Come On... Are You So Unhappy With Yourself That You Feel The Need To Try Ostracize Someone With A Psychological Problem That Doesn't Allow Him To Type The Way You Would Like Him To? I Didn't Want To Say It Before, But In Light Of Your Ignorance I Feel I Must Enlighten You, I Have OCD And Capitalizing The Beginning Of Every Word Is One Of My Rituals, If I Don't Give In To This Compulsion I Feel A Large Amount Of Anxiety, And Because It Is A Relatively Harmless Compulsion, My Doctor Is Focusing On Other, More Pressing Matters, The Only Time It Really Becomes A Problem Is When People Like You Criticize My Typing, While Appearing To Portray Themselves As Perfect (Which 99.9% Of The Time They Are Far From Perfect) In A Post Which Has More Mistakes In Proper English Than The Eccentricities In My Post Has.
