Soldered all of the LM324 quad amp IC'sSide that is more beveled is where pin 1 isIncorrectly oriented the first one, bought a heat gun to de-solder and re-orient itBought isopropyl alcohol pcb cleaner to clean flux and solder residueOrganized bags containing...
Attempted to solder capacitor onto area with broken pad by soldering to the trace after scrapping the protection offWas able to scrape protection off, but was not able to get solder to stick to the exposed copperEnded up making the situation worseThe...
Soldered all SMT components that weren't lost/destroyed/had a pad that rippedOrdered replacements for:C1 C19 C21,C22,C37,C39,C40,C41,C42 C47,C48,C49,C52,C53,C57,C58 C60,C61 R21 R56 R58 R59 R60 R66,R67,R70...
Des-soldered the first LM324 IC and re-soldered it in the correct orientationCleaned excess flux on the boardSoldered U17, U18 and Q1***Going to wait until I've soldered every component and tested the board before I buy replacement for C60 &C61 in case...
Thought Experiment: You solder a very tiny connector to an breakoutboard to try beep out the thing you connected to that connector. You find a few connections but for Farad sake you can not find others. You totally must have broken some connections on...
SolderI know you'd rather hear about the solder, so I'll start there. The central part of the electronics is the Teensy3.2, Audio adapter, and LED driver(ATMega328) which all stack together in a small package. First take a look at the picture. The perfboard...
It's been another day, full of...soldering. To cover the high demand, I've been hard at work producing more units for those interested in helping the network expand. Here's more than 20 PCBs. Tubes will be added later, also the software, and the calibration...
ok, again repopulating the board with the components grouped by function (the raspberry-zero and the powerboost 500 are already mounted)first: soft-powerconnecting the lipo battery and hitting the power button the pi boots, and pulling the gpio down...
Version 2.0 of the Scrobble Box is actually in a box. The box is a shell that my wife had lying around from another project, and the Pi Pico W is mounted inside on a knock-off Pop Socket with double stick tape. I mounted a battery pack I scavenged...
I opted to bond the two pieces of pad back together with a large plastic sheet (icecream lid). I scored the top of the pad and plastic sheet to allow for good glue stickyness (I'm not sure it acually helped any. I glued along the seam first Then I attached...
My most recent JLCPCB order arrived today, which contained:The i2s soundcard based around the TLV320AIC3104 from TI.Breakout board for the AXK770147G used to connect the logic board to the portrait dock connector daughterboard.Breakout board for the...
So, the parts finally arrived! Last Wednesday, actually. Delivery time was a week or two longer than expected, but for the price of production and shipping, I'm not complaining.Regardless of this, the quality of the PCB and solder paste stencil was excellent,...
putting the components for the audio filter in, only for one channel though - since there will be a follow-up revision to address the other bugs found so far. still this tells us if audio this way works or notand it does! :-Dsomewhat audible sound came...
So if it wasn't clear, I'm pretty new at PCBs and such. I only kinda have a feel for my multimeter. Assembling and repairing something visibly broken, though, I'm solid. With the most recent set of this project, I took reference photos of the mechanism...
