Homebrew PCBs

Hi Chris,

I've been working on a R220 on and off for a while now. The most 
annoying thing is the positioning of the CD tray. It is finicky. One 
note: if you create two addtional "thumbholds" in the tray you can 
print on a 4.25" square board. This is about the minimumb hack needed.

You may have a problem getting the cartiridge re-filled with another 
kind of ink. I tried Island Inkjet and they refused to do it. They do 
not completely flush out the cartridge before refilling and were 
concerned about incompatibilities betweeen inks and cpntaminting 
thier ink supply.

I was just given a C88, which uses the pigment inks. I haven't tried 
it yet but it looks like the cartridges will fit. I'm not sure about 
the "chips" though.

As for a heater, consider a long aquarium heater. I'm not sure how it 
wil "survive" outside of water but they are pretty cheap.
