Re: Hacking the HP45

I have put the UDN2987 on my list of considerations. It has a latch, can handle the voltages and does seem to be (barely) fast enough. The discontinued status and max 1000ns response time do worry me a bit though. Once I am certain that the TLC59213 is indeed the bottleneck I will see if this chip ...

Re: Hacking the Xaar 128 printhead

Hi all, I have been trying to print using the XAAR 128 for some time now, but I can't get all the nozzles to print. The data is being sent correctly and electrically everything seems fine. I have flushed the print head several times and the problem persists. I have attached pictures of the setup an...

There are SPI lines broken out for for further expansion as well as 4 d...

Re: Hacking the Xaar 128 printhead

I am interested in your board. Do you have any of them left? What would shipping cost to USA? Yes I still have them. Well I make them on order so I will always have them :). Very little because I live in USA as well. Though the price includes shipping so no one has to worry about the shipping costs

Re: Hacking the Xaar 128 printhead

What is new in this board that haven’t been discussed before in this forum? How would one use this board? I don't know if there is anything new in the board per se.
