Re: Super Sixteen build support thread

Yep, you should just be able to replace the trace by soldering a wire where it would go. Typically this is done with very fine solid-core wire called "mod wire" "kynar wire" or "wire wrap wire", but you can use anything you've got around. If you've only got some stranded wire, it's probably best to...

Re: Super Sixteen build support thread

Hi Thanks again so : The 680 ohm resistor should connect to the nearby header pin The header pin should connect to the opposite header (test this! a pin could be bent or cracked) The opposite header should connect to the atmega pin 12. Yes it's ok . The final cpu-board trace may be harder to follow ...

Re: Super Sixteen build support thread

It should be easy enough to test this theory. Unplug the module and use your multimeter in diode test mode. Connect the positive probe to the display's top row, 3rd pin from right. Connect the negative probe to the top leg of any of the nearby 7 resistors to the right of the display. You should see...

Re: Super Sixteen build support thread

Thanks for the answer but i think i will need to go deeper. I check header pins with my multimeter in continuity mode, i replace the Q1,Q2,Q3 3906 transistors, i measure R14,R15,R16. I reflux all this connections ( including the screen) and still no second number... Perhaps the screen is broken? For...

Re: Super Sixteen build support thread

Hi The pdf and the video are very clear thanks for that. I just finish the build, but i have two problems : -The second number in the screen doesn't work. -no gate on output. I think soldering points are all ok, all ics are well powered, all the ground i can check are ok. Do you have an idea to fix ...
