Diy Electronic Kit LED Gyro DIY Welding Kit Rotating Lantern Inline Components Diy Electronic Sodering Project(without Battery)….. Ali Express .78 cents

Well maybe not a fidgit spinner per say but a small soldering project to take a break from troubleshooting.

For the geek type, schematic, RC time constants etc

Just 2 resistors to differentiate and correct polarity on the LEDS All items silk screened on the board .

care of Ali Express

critique solder skills

touched up a few of the welds after this for appearance

I used CR2025 batteries, OK

Apparently a chopper circuit to give you the effect of the individual LEDS vs. a single solid line of light. Camera only picking up 1/2 or less.

A lighted spinner for your fidget

Note to self: order soldering iron tips

ON THE BENCH :KEURIG K35

ANOTHER BLUE MAT GROUP SERIES

CONTINUOUS RUN, INTERMITTENT RUN, INCORRECT CUP SIZE WATER OUTPUT

PUMP PROBLEMS?

SOMETIMES KEURIGS CAN BE FUSSY MACHINES ALWAYS HAVE HAD ONE. CONSIDERING THAT THIS IS THE MR COFFEE MACHINE MODERN REPLACEMENT AND IS USED AT LEAST ON A DAILY BASIS WHEN THEY RUN THEY ARE RELIABLE. SOME HAVE THE FEATURE TO INDICATE DE SCALING PROCEDURES NEEDED WHICH SHOULD BE DONE ON A REGULAR BASIS LIKE ESPRESSO MACHINES AND SOME TYPES OF WATER HEATERS FOR DOMESTIC HOT WATER.

THIS K35 ONE FROM A FAMILY MEMBER. DECIDED TO DO A TEAR DOWN OF THE PUMP JUST TO MAKE SURE IT WASN’T CLOGGED ETC.

ALSO THOSE INTERESTED IN MODS AND UP CYCLE CAN TAKE A LOOK

A YOUTUBE SEARCH REVELED HOW TO REMOVE THE CASINGS, JUST SOME SCREWS AT THE BOTTOM AND THE USUAL CLIPS

THE MAIN CIRCUIT BOARD. NOTICE THE 4 PINS IN THE LOWER RIGHT CORNER FOR ? ACCESSIBLE THROUGH A REMOVABLE COVER ON THE BOTTOM OF THE UNIT. DIDN’T DO AN EXHAUSTIVE SEARCH FOR THIS. NICE ! JST TYPE CONNECTORS ON THE CONNECTIONS

THE PUMP UN CLIPS FROM A MOUNT AND TUBING EASILY REMOVED.

CONNECTOR IS FOR SENSOR INSIDE THE PUMP , RED/ BLACK FOR 12 VDC POWER TO THE MOTOR NO PICTURES OF THE PUMP DIS ASSEMBLED, AN INTERESTING OFFSET DRIVE AND A SERIES OF TRI SPACE DIAPHRAGMS THAT DO THE PUMPING ACTION. I CONNECTED 12 VDC TO PUMP TO INSURE IT WASN’T STALLED OR DEFECTIVE.

DIDN’T APPEAR CLOGGED AND EASILY RE ASSEMBLED. CLIPS HOLD THE PUMP TO THE SEALED MOTOR.

_{^{TYPICAL WORK BENCH ENVIRONMENT}}, _{^{NOT A PROBLEM FOR ME.}}

THE PUMP IN PLACE

RED BLACK 12 VDC POWER

REASSEMBLED AND CUP SIZE WAS STILL OFF , LARGE WAS ALMOST 2 CUPS WATER OUTPUT. RAN THROUGH THE ABOVE PROCEDURE AND NOW THE KEURIG WATER OUTPUT IS WITH IN SPECIFICATIONS WILL CONTINUE TO BREW A FEW CUPS TO TEST.

THANKS FOR VIEWING, HAVE A CUP OF COFFEE.
