I've had this same soldering iron tip cleaning thing for so long (over 15 years), all the bits of solder have turned into balls. It's getting tovthe point where i should probably replace it.
I really want to heat it up some how and make one ball of solder. Just for fun.
I'm not sure how to do it though. #electronics #soldering
As far as I'm concerned, proficiency with soldering is a prerequisite for rabbit ownership. Otherwise you're going to be buying a lot of power cables.
Of course, you'll probably still have to from time to time 
They look so nice and clean when they are fresh out of the post-recapping bath. No more dust or capacitor scum or flux. Almost like the day it came off the assembly line.
The Mac Centris 610 is mine and my son made the other two. I just washed them in alcohol to clean them up for him.
What a day at Tog Hackerspace!
Today’s Build Your Own RISC-V Computer workshop was a massive success. Participants soldered up their Olimex RVPC kits, learned to program them, and went home with fully working RISC-V computers they built themselves. 
Big thanks to everyone who joined us — the smell of solder and the buzz of learning filled the space! Stay tuned for more hands-on workshops like this.
"Bitte ein Bit"
Single ferrite core memory bit, 1.3 mm diameter, 0.4 mm thickness. 0.15mm magnet wire. One vertical wire, one horizontal wire, and one sense wire diagonally.
Magnetizing current roughly 600mA, so 300mA for coincident current addressing.

Is there some (very) cheap controller / tinkerboard with *lots* of GPIO pins?
Need one for extensive communication with other ESP8266. I live in an apartment building and definitely don't want to put dozens of them in a massive WPA2-only network, especially not those that control rather important things like door switches.
So my goal is to connect them with bell wire and write my own tiny signal library. I need one master device with lots of GPIO + RJ45 though.

„Kommt Zeit, kommt Rat!“
In diesen verrückten Zeiten, auf dieser kranken Welt hilft nur eins: Abwarten und Uhren löten! 
Heute mal wieder eine Scope-Clock gebastelt… #vintagescopes #hameg #diy #soldering
Got a Pi 4B with a torn CPU the other day. Removed the lead free solder residue and discovered that a few pads were torn. One of them is important, so had to repair it with 0.02mm wire. I still can't believe it, but it works .
Being a ham radio operator has given me the gift of being able to solder, and thus save a bunch of money fixing things that we’d either otherwise throw out or have to take to a shop.
Here are my two latest projects: fixing our busted instant pot, and the broken toggle switch on my bass guitar.
so jetzatle auch im shop: ESP32 C3 SuperMini https://shop.blinkyparts.com/de/ESP32-C3-SuperMini-Kompaktes-WiFi-Bluetooth-5.0-Modul-mit-USB-C/blink23158
Fehlt nur mal ne Wiki-Seite mit nem Überblick über die ganzen ESPs, da blickt man bald nicht mehr druch. Gibts da ne gute Quelle?
Wer kommt denn eigentlich so auf die #MakerFair in Hannover?
Ich werd dort wieder auf der Bühne (Niedersachsenhalle Stand 14) sein und freu mich wenn ihr Hallo sagt :)

This is the Stonehenge #soldering challenge I plan to bring to #why2025 camp.
The standing stones are SMD ferrites, the horizontal 
on top are LEDs which are connected to a CH32V203 MCU. A few capacitors a sprinkled in for the flat stones.
The design was done in #KiCad using plenty of custom footprints to get the right look.
The artwork was not done by me, but gifted by a unnamed person 
It has not been properly tested and might not arrive on time though. Wish me luck.
Woha mega! Wir haben es wieder in die @MakeMagazinDE geschafft \o/
Dieses mal mit unseren Solarpunk Synthesizer 
electric cats, a simple question for you: I have an electric guitar with a 5 way switch (2 dual humbuckers, 1 single coil). The 5 way switch is wired such that positions 0, 2, and 4 are neck humbucker only, single coil only, bridge humbucker only.
I swapped them out recently and those positions work 'fine' (except I think I soldered the wrong pickups to the wrong position, but hey, it's symmetrical, who cares?).
Positions 1 and 3 are a combination of a single pickup from the humbucker (split) and the middle single coil, and these are much more compressed and lower volume than the other positions. I think I fucked up the soldering and suspected I did something like swap the hot and the ground wires for each humbucker.
My question: A, without pictures or more information, does that make sense/seem plausible? B, would this be an easy to answer question if I gave more info and some pictures? C., ... what would this phenomenon even be called so that I might be able to look it up more in depth to see where I went wrong? It's like they're almost perfectly out of phase, or something; the reduction in volume and compression reminds me of destructive addition.
I wasn't able to find exact wiring diagrams for the new pickups (some inexpensive licensed duncans that are apparently duncans in name only) but the Ibanez wiring diagrams are easy enough to find. Any help or insight anyone can give would be super appreciated! It's still quite playable, as I largely just avoid positions 1 and 3 right now.
Thank you! reboosting totes appreciated

Can anyone help me out with this? I’ve tried soldering wick, flux and extra tinning to try and get rid of it! I just want clear holes to put my switches pins through! I’ve tried both sides too #electronics #soldering
No, I didn't solder a very clearly marked polarized electrolytic capacitor backwards across the power rails of my project board tonight, causing it to smell funny, emit a loud POP, and spit its guts across the room.
Not that you can prove, anyway.
So, hab mal das Video zum Axolotl (wieder) hochgeladen!
Ich drehe und wende den Bausatz in der Kamera und zeige euch ein paar mehr Details:
I finished up teaching 2 week neon and STEM class at Urbanglass on Friday. The high schoolers were from all over NYC with varied backgrounds/ schooling and they all made such fun things!
Along with my two TAs (Caroline and MolMol) we taught them not only how to wire and bend neon tubes, but also how to solder (SMT and through hole) and the very basics on programming captive portal ESP32 chips for blinking neon with phones.
We played games, Including making a 30 foot mega straw for fruit punch, competing with three glass an food coloring "rollercoasters" as well as numerous "drop test" contests to test/ build bend/ weld strength.
Overall they learned about planning, pereeverance and some the hard lessons of loss that glass can teach so well when the thing you make breaks.
One student quoted Don Quixote "Without hardships there can be no Adventure!" - couldn't have said it better myself :)
