Tindie stock? #2
Comments

@MickMake Any idea on whether or not we can get a resolution to this? It would definitely help and save me time from laying out a new breakout board! |
|
@MickMake If you are not going to restock these boards can you please upload gerbers so we can order our own? Thanks, just got 2 DLP's for a project. |

FWIW, I came across https://www.pcbway.com/project/shareproject/Pi_Zero_to_TI_Pico_Projector_Board.html while looking for something else, but I haven't tried it myself, so caveat emptor. I ended up wiring a board up myself by hand that has been running atop a Pi 3 for a few months now. Been planning to do a write up about it with pictures, but haven't had the time. I was able to implement it with 2 GPIO pins free for other things (in addition to i2c which is shared). |
did you or anyone else have a chance to try this? Edit: anyway I've ordered it, so I'll let you all know |
|
I have not looked into this. have not had time.

So the board at https://www.pcbway.com/project/shareproject/Pi_Zero_to_TI_Pico_Projector_Board.html was useful. It works! It fixed the shaking screen issue I had while using cables and no board. The board was created by Sean Hodgins who wrote https://www.instructables.com/Face-Changing-Projection-Mask-Be-Anything/, which means the tutorial must be followed:
I'm thinking of writing a full tutorial but until I haven't, feel free to ask any question and I will try to answer |

@stephanebruckert I only have 1 issue that I can't really figure out and it seems like all forums about that issue has been closed. I can't get the raspberry pi zero to show any image on the DLP2000. I've followed this guide: http://frederickvandenbosch.be/?p=2948 And also tried the configs here in this GitHub project but nothing other than the projectors default screen. Basically seems like I get the same issue as this guy is quoting here: https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/844615/dlpdlcr2000evm-evm-with-raspberry-pi4 Can anyone please give me a helping hand? :) |

Pi Zero W |
|
So my setup is basically the same as this guide here: |
|
Ok I think I know why. I had the same problem and found the answer in some forum. In the tutorial it says but for Pi Zero we need to add save that and make sure you reboot |
|
Seems like it's at least trying to do something now. |
|
and I can now get information when running |

I remember adding some more lines to the end of $ cat /boot/config.txt

FYI I started from this tutorial https://www.mickmake.com/post/build-a-pi-zero-w-pocket-projector-project/ The part about enabling i2c is probably important. I assume it is what |
|
Will have a look at that. |
"it", the projector or raspberry? Asking because the rainbow screen is part of the DLP and the DLP doesn't have an HDMI, so I don't understand how that is possible |
|
Sorry, Disables HDMI output. On other notes the last 5 rows does not seem to solve my issue. no output to projector.. Really appreciate the help! |

Any news on this? |
I've been checking off and on, but your status for both revisions of the board at Tindie has been out of stock for some time... are you expecting to restock at some point?
If not, would it be possible for you to publish the PCB sources or Gerber files, for any version even if it's not the latest and greatest, here so we can have our own boards made?
