UFC build #3

Closed Kerube closed 4 years ago

Kerube commented 4 years ago

Hi Same here, did no find a way to contact you. I have completed the electronics assembly of the board but have a few questions regarding the values of R9,7,5,10,11,12 I could not find the values anywhere so I placed 0 ohms resistors for the time being. I have not powered the board yet, and I think I will have a few questions on the software loading. Hope to hear from you.

Regards

I'd be very interested to know how you completed the electronics assembly in great detail....

Hi Phil I sent the boards to be built in China using the fabrication files provided. I ordered the parts online from different vendors. Had a hard time finding the HOLTEK HT16K33 chip by itself, ended up buying the Adafuit board and removing the chip to use it on the UFC. Purchased the Gateron switches and added the green LEDs, I recommend you try to find them with the LEDs, it will save you some time. In overall assembling the board is easy. I am just waiting to find out the values of he resistors listed above, after that I will power it up and try to load the software. Hopefully it will work as planned.

Thanks for that - appreciated

To clarify in my mind, you are referring to Resistors R5,7,9,10,11 & 12 on the UFC board, not the DCS controller...

(I couldn't find their values in the CSV Bill of Materials file Hornet UFC 020a BOM.csv)

Phil

Kerube commented 4 years ago

Correct. I found some online schematics showing that those resistors range from 100 to 150 ohms and 10k for the encoder pull up. I will try those values this weekend and see how it goes.

If it does not work, I will have to wait until the OPENHORNET team finish their design and go from there.

psjshep commented 4 years ago

Good luck... keep us posted

Phil

psjshep commented 4 years ago

I'm not sure if this is the answer to your resistor query... but when I opened the files in the Eagle program for the UFC board...

Inside the

\CAMOutputs\assembly is a CSV file PnP_Hornet UFC 020a_back.csv

Could those be the values, bearing in mind I have no idea what I'm doing in that prog LOL ?

Edit Looks like the 270 is some other column value....possibly the rotation degrees... the other rows with capacity & resistor values is blank for the ones you need... o well :(

Kerube commented 4 years ago

cool, the values are there, I don't get to see them when I open the excel file. Nice

Thanks Phil God job.

psjshep commented 4 years ago

note the edit :(

BlueFinBima commented 4 years ago

Sorry for ignoring you (not deliberately). Once I find my eagle VM, I'll take a look for values. Failing that, I'll open up a UFC and take a look ;-)

BlueFinBima commented 4 years ago

OK, Resistors R5,7,9,10,11 & 12 are for the RGB LEDs if you're using them. https://www.allaboutcircuits.com/tools/led-resistor-calculator/ . I didn't use the RGB encoder in the end. I'll add a PDF of the schematic to the repo.

psjshep commented 4 years ago

nice 1 - thank you....

Phil

Kerube commented 4 years ago

Ah, good. Thank you BlueFin. I will finish assembling he controller board soon and then I should be able to load the software and start getting to work.

Regards

BlueFinBima commented 4 years ago

@Kerube Yes 10K on the encoder pull-ups. Aliexpress provided my HT16K33's (slow and cheap) but my prototyping IC came from Adafruit, just like yours. If you want to, let me know your email address, and I can invite you to a Slack channel if more communication is useful.

Kerube commented 4 years ago

thank you so much. Here is my email kerube23@gmail.com

Closing.. moved discussion to slack
