Introduction: Run a Printing machine in Your Car

You may have needed or will need, in your lifetime, to print an important document while you are away from home. You English hawthorn have resorted to finding an cyberspace cafe to print out so much a text file, but such places are risky in terms operating theatre privacy and confidentiality. If only you were capable to power your Inkjet Printer you have at home, from your Car, and print that all important document as and when needed.

Well, that's what we will be solving in this instructable. I will be showing you how to relate and power an Inkjet Printer from your Car, and all it will take is a few hours of your time ready to build the power supply. Lets get to it shall we.

List of necessary items:

  1. Elastic enclosure - 1
  2. Mini Voltmeter - 1
  3. 150W Step to the fore Boost Convertor - 1
  4. 12v Fan - 1
  5. 10A Wires
  6. 12V Male Connector - 1
  7. 12V Female Connector - 2
  8. 10A Primer (Optional - required if the power draw is very high) - 1
  9. Car Cigarette Lighter Connector - 1
  10. Connector matching the Printing machine Great power Supply Output - 1
  11. Crackers and Bolts

Number of requisite tools:

  1. Flat Head Screwdriver
  2. Unerect Nose Pliers
  3. Telegraph Cutter
  4. Soldering Iron and Solder
  5. Mini Breadboard
  6. Dupont Male and Female Cables
  7. Voltmeter
  8. Heatshrink Tube

Step 1: Assembly

I screwed in the 150W Boost Converter to the base of the plastic casing. I as wel screwed in the miniskirt voltmeter to the meridian of the shell at the opening which I carved unsuccessful advance.

The cooling fan was screwed into the sidelong in orderliness to cool down the boost converter since it gets eager if a lot of current flows finished IT.

A 12V Female connector was secured into the side as healthy exploitation the nut which it came on with.

I also inserted a wire into the casing which already had a 12V Staminate Connector at its other end.

Step 2: Wire Connections

The antagonistic or BLACK wires of the Voltmeter, the Cooling Fan and the Power In connexion (which is the 12 V female connector we added earlier), should equal connected to VIN- of the Further Converter.

The positive or RED wires of the Voltmeter, the Cooling Rooter and the Power In connector should constitute connected to VIN+ of the Boost Converter.

The negative or African-American telegraph of the Power Come out wire should cost connected to VOUT- of the Boost Converter.

The incontrovertible or RED wire of the Baron OUT and the Yellow wire of the Voltmeter should represent connected to VOUT+ of the Boost Convertor.

To get a better connector, you can solder in the wires.

Make a point of the polarity when connecting the wires jointly.

Measure 3: Hacking the Printer

Directly its fourth dimension to hack the printer.

I used a Canon IP2770 inkjet printer for this project.

I secondhand a screwdriver to loosen the lock which holds the power provide in commit. Don't use too much ram or you may wrong the printer.

This power supply states that information technology outputs 24 Volts, thusly we motivation to set the boost converter to output 24 Volts.

But I came crosswise an issue

The power supply has 3 terminals for power out, so which cardinal outputs 24 volts?

I used a voltmeter to find out the two correct terminals, and I also used some Dupont cables and a mini breadboard to nominate the necessary connections.

Once I found out the accurate terminals, I marked them so that I do not get them confused subsequent.

Step 4: Printer Power Connecter

I soldered in some wires to a 12 V female connection and connected that to a matching connector of the printer power supply, so that the original power supply privy be easily removed as and when needed.

I also used heatshrink to insulated the connections. We dont want whatsoever unnecessary bangs.

Step 5: Adjusting the Output Voltage

The slim blue potentiometer connected the boost converter should be turned ready to increase the output voltage upto 24 Volts, which is the required voltage by the inkjet pressman.

Afterwards I out of use leading the cover and got in my car.

Step 6: Plugging in the Components to the Car

I connected the Car power to the input of the Boost Converter and thereafter connected IT to the input of the Inkjet Printer using the connective wire I made earlier.

Step 7: Printing

Afterwards the printer is hopped-up up, I sent an image file to the printer to be printed.

It with success printed the image.

Hope this project helps.
