Well, that went better than expected. I won something with the Orrery. It did even better than I had hoped. I would have been happy with a t-shirt. Up to the next project.

Re: Hacking the HP45
2 announcements, no new progress. 1: I have seen the future. THIS: http://hackaday.com/2016/08/17/introducing-the-teensy-3-5-and-3-6/ . I had preferred the Teensy over the Arduino DUE for the Oasis controller, but until now I had problems with the Teensy having too few I/O pins. No more it seems. I ...

Re: Hacking the HP45
@ Jurif: I currently do not use eagle, so I cannot check whether the library is correct, but I will see if I can get a version so I can check it. @Bigbomber: As mentioned by Dragonator, the high level pulse width for Fet of each nozzle is about 2 us. To ensure the duration of pulse, I've used a 555 ...

Re: The T60 power armor
I said a few months ago that I would not resume the power armor project for a few more months. That was may, it is now august, and it is a few months later. Time to pick things up where I left. The reason I stopped was that I a major concept change that needed some thought. I would go from a wooden ...

Re: Hacking the HP45
Not yet, but I now know how to measure these heads to get a good idea of the pinouts. I first want to get the HP45 working.

Re: Hacking the HP45
And this is what the new version of the PCB should look like if nothing changes. I still need to do the 3.3V tests, but right now all components should be able to handle 3.3V, so I am not that worried. The basic changes are this. The whole address side was changed to now have HEF4017 and HCF4081 chi...

Re: Hacking the HP45
"If it looks stupid but it works, it isn't stupid" -the Internet a few days ago I was plagued by a nozzle test function that could not get above 1V, too low for testing. This was because when the ground was closed on the printhead, the voltage was being drained through the internal pulldow...

Monster hunter statue
For a wedding present/cake topper I was asked by a friend to make a statue of Monster Hunter with a Rathalos and Rathian. Not shying away from a challenge, I accepted. Here is the short version of a 3-4 week process. I can do a lot, but I cannot design this kind of models. The first thing I did was ...

Re: Hacking the HP45
2 steps forward, 1 step back. The 4017 works like a charm while printing, but a small issue was found. The test nozzle function I used to test the condition appears to be broken. I have found it to work less with the MIC5891 test and lowered the threshold voltage so it would work again. I had to low...

Re: Hacking the HP45
A words only update, no pictures. The way it seems right now, the 4017 connected to the printhead has a shutdown time of 1-2us. This is good, this is what it needs to be. I need some more testing to double check whether the connections to the printhead were sound, but this looks good. So now I can l...
