This is a community I've missed since leaving Reddit, but I didn't expect to find or create such a /~group here given Tildes is a much smaller community (I figured, statistically, there wouldn't be enough users with overlapping interests in Right to Repair / Electronics / 3D Printing / Makerspace / etc... for such a community to be present or to naturally form here.

With the recent post asking for advice on a soldering station, and the number of users that participated in that discussion, I've been rethinking those assumptions of 'not enough users / not enough interest'. Then I further reflected on the significant number of people we have here that have fluently discussed other technical areas such as Linux, Programming, servers / Homelab topics and I realize upon reflection that a fair many of our users here are pretty high on tech literacy...

So, as a prelude to requesting a new group like /~electronics or /~makers or some group name along that philosophical theme, I wanted to ask the community at large first as to how much interest there might be in this.

Do you, dear reader, have an interest in electronics repair? In a garage workshop or other space at home where you fix or build things? Makerspace topics like 3D printing? Right to Repair law? If you want to know how to replace your cell phone screen, or ask about soldering or Raspberry Pi or Arduino, are you interested in having a place here on Tildes specifically for these things? Please, if you have such interests, let's discuss here.

Soldering/electronics repair enthusiasts: I am in need of a soldering iron/station for electronics repair and wiring, preferred budget is under $150, perfection can raise the budget to $250.

First line of this post is all that's really needed if you just want to provide advice on what to buy (which is just fine, people don't need to know how a car works for me to explain that they probably just need a minivan).
Below is what I have gathered thus far if perhaps there's more that you'd like to know about what I've seen and perhaps misunderstood so far.

At present I have a no-name, non-adjustable, extremely basic soldering iron that is more fire hazard than anything and a Weller soldering gun that is obviously not meant for electronics and small wires. The iron has been good enough for the occasional need to solder a couple of wires together to get something broken back up and working, but is not something I'd use on anything critical.

Came home today and found wet clothes in the dryer. Which was weird because earlier, I had found the same load in there wet and just thought I had forgotten to start the dryer. Low and behold, when I stood and watched it, about ten seconds after starting it, it started beeping and gave out an F01 error code.

While googling it, it seemed that the code meant the relay electronics board had failed and needed to be replaced. I thought, I can probably do that, but the board seemed to be more than $150, which is more than the callout fee on our home warranty ($125). But what we most needed was a working dryer!

While looking for the exact price and a source to order the board, I found this video describing a simple fix for a blown solder connection. I unplugged the washer, opened it up, and the board was blown in the exact same spot as in the video. I soldered a jumper in, put it back together, and lo and behold, the dryer runs!

I have an undergraduate degree in electrical engineering, even though it hasn't been my day job in a long time. So I could at least evaluate the plausibility of the fix, and I had the tools and know-how to do the soldering. So definitely not a fix for everyone.

Money is tight right now, so fixing the dryer for $0 (and in half an hour no less) was big for us. Sometimes you need a win, and today was a day I really needed one!

What fixes around the house are you most proud of, saved you some money, or kept a piece of equipment out of the landfill?

Someone recently asked me to replace the battery in their old iPod, and I found myself wondering what I should do with the old battery. It still works, but has less capacity than when it was new. So I looked around my workshop and found some of these surface mount LEDs and decided to test the limits of my soldering skills and make a flashlight out of them.

These LEDs are very hard to solder, since they're surface-mount and the pads are on the bottom of the LED. They were never meant to be soldered by hand, but rather placed by machine onto a specific amount of solder paste, which is then baked in a fancy oven at very specific temperatures for very specific times. To solder these by hand, you need to create a liquid puddle of solder and sorta float the LED on top, while being careful to not short the pads which are very close together as well as not overheating the LED. The temperature the plastic melts at seems to be only a few degrees higher than the solder melts at.

I wired up 5 of the LEDs in parallel, each with its own 6.8ohm resistor wired in series with the LED. This should limit the current to 150mA per LED. I hot glued this in place, as well as a lithium battery charging circuit I got off ebay for a dollar. Here's one such listing.

I slapped on a pushbutton, and Bob's your uncle! It worked first try!

Here's a blurry picture of the finished product. I'm pretty proud of how it came out, considering how tiny and fiddly the soldering was. And, I think I'll actually get some use out of it too. The battery ought to last at least an hour of runtime, and the thing is seriously bright.

Anyone here into electronics as a hobby?
