I missed to route two traces from a Raspberry Pi Compute Module socket (my acrrier board) and had to rework. The pad has a width of 0.2mm (.0080"), so I got extra a new tip for that (Weller LT 1LX). After two attempts I could successfully tack the bodgewire to the unconnected pads.

Quite an interesting failure - not something I've seen before.

For those interested, this is inside a PA amplifier, which surprisingly does still function, although this may be for the untested channel. PAT sticker from 2005 so at least 20 years old.

Hello everyone. This is the PCB I came up with. Its to simplify the setup of certain hardware laboratories controllers that I also came up with previously. Took me couple of days (around 4-5 hrs) of work to solder them all 40 boards. But this will make super easy to connect things, or replace the microcontroller in case of a failure.

As my very first design (this is slightly revamped to add small "window" to see the status LED's on nucleo board), I once again, feel really proud, haha.

The revamp also added another 6 blank pins for future expansion (there are plans to add dynamixel robot arms to controllable devices repertoire).

Wanted to change the current limiting resistor on this DRV8871 motor driver board. Didn't want to wait for the correct component to used a through-hole resistor on 0603 pads.

I love seeing boards that have hidden messages or pictures on them

After a long time trying to make a circuit board in house for a QFN package, I have a working ATtiny 841 blinking an LED.

QFN unlocked!!

I bought this display from Alibaba, and then created PCB with JLCPCB. Refresh rate 60Hz with STM32.

1. AMP control board
2. AMP IC and Output board

I will complete to make Input board and Vol control, LED EQ

I have been looking for larger quality boards for some time now and I just picked these up today! I was so excited to get them at that price I felt like I had to share!

I am currently taking this course from IIT madras by professor hashtag#DrAnanthKrishnan to deepen my understanding on TL theory and how EM waves behaves inside a Transmission Line Theory.

TL theory is actually what all the physics and electronics goes behind PCB traces, PCB traces are actually strip/microstrip transmission line..

and this lecture on NPTEL https://lnkd.in/d5kqdT_2 is one of the best lecture for developing understanding of TL & EM waves from India's one of the best professors...

I recommend this course to engineering students and freshies who are willing to build career in High Speed PCB designs.

PS:- unfortunately this subject was not thought to us properly by my professors, but now this is what I have to deal with everyday, so every lecture in engineering college is important and it will help you someday, when your simulation tool is not working and you have to belive in your engineering intutions. don't miss your lectures

Hi firstly ım 15 thats my full adder and it works ım very happy rn ı bought pcb from jlcpcb and ı use zipties to organize the cables , and ı use my ardunio to power up this thing so thats all you can ask questions and you can see everything on the photos
