About this project
What is an InkShield?
This shield allows you to connect a HP C6602 inkjet cartridge to your Arduino turning it into a 96dpi print platform. It only uses 5 pins which can be jumper selected to avoid other shields. It is designed with a Arduino Mega footprint but fully supports both the Arduino and the Arduino Mega. It is designed with all through-hole components to make assembly easy even for beginners.
- Compatible with Arduino and Arduino Mega
- Uses only 5 user selectable pins
- Stackable (up to 11 Inkshields on Ardunio, 15 on Mega)
- On-board 18.5V boost converter for Inkjet head
- Accepts 9-12V input via optional power connector or from the Vin of the Arduino
- Auxiliary input header offers support for other microcontrollers
- Auxiliary output header supports an extension cable to the inkjet head
- Power and Pulse activity LEDs
- ISCP header and Reset button
- All through-hole components
Current Status of the InkShield
I made an initial prototype followed by a second prototype to correct a few minor errors and make several improvements. I am currently working on a few minor adjustments and the details of the Arduino library to support this shield. This goal of this project is to gather funds for the initial production run of at least 100 copies of this shield.
All source code (both hardware and software) will be fully Open Source and released when the initial production run is completed.
NOTE: the following images show the most current designs as of the start of the Kickstarter. There will be minor updates to the sticker design, PCB layout, and final kit components. This is all in a effort to produce the best possible kits for you. Watch for updates as things progress.
The initial sticker design:
The complete kit (does not include ink or ink carrier):
The assembled kit (does not include ink or ink carrier):
The optional "extras":
It is more for art, hobby, and educational use than for replacing current printers. The Arduino (which is what this kit is designed to work with) is a small programmable board for electronics projects. It helps to ease the learning curve and allow more people to get involved in electronics.
Here are some examples of projects done with an older board like this (which is no longer available):
This one is a scratch-built inkjet project:
and these two are mine using an early version of my board:
Information about buying a kit will be available here:
There are reward levels which include ink either a single cartridge (in a choice of black, red, blue, or green) or all four colors.
One source of additional ink is: http://www.transactsupplies.com/store/Hp-C6602-Inkjet-Cartridges-p-1-c-333.html
Yes, there are Hackerspace packs of 10 at a discount which anyone can select OR if you just want a few select the reward level you want and double, triple, etc.. the pledge amount. (i.e. select the $10 "PCB only" reward and pledge $30 to receive 3 PCBs).
Here is a site I currently know about that has that information: http://www.c6602a.com (DISCLAIMER: I am not affiliated with them and have not validated their information. The site seems to be affiliated with InkOasis) This page lists printers for the C6602 cartridge: http://www.c6602a.com/2010/05/c6602a-black-ink-cartridges.html This page lists printers for the older 51604 cartridge which should be compatible with this shield (but is currently untested): http://www.c6602a.com/2010/11/hp-51604a-ink-cartridge.html
The inkjet head this was designed for is the C6602 series. It should also work with the older 51604A series (but will need a different carrier).
Here is some documentation on these heads:
It may also be possible to use this shield to drive other models of inkjet head although none have been attempted.
I do not know the exact spray angle. However I can tell you it is narrow and from these tests it looks to be about 18 degrees: http://www.flickr.com/photos/nicholasclewis/6142938466/in/photostream
These tests also show that it does work to 90mm from the print surface but is very sparse. It should work farther than that but at rapidly diminishing quality. Anything over 30-45mm will not give good results for printing any patterns besides a "blackout" pattern (as in the pictures).
According to http://sysdoc.doors.ch/HP/5981-9514EN.pdf the recommended print distance is 2.54-4.1mm.
