Dear scielectronicsbasics people, I am 65 and was recently diagnosed with essential tremor. It is not Parkinsons and is not a serious health threat. (Bill Clinton was diagnosed with it a few years ago). Basically it means that my hands shake a little bit. This shaking now makes soldering difficult. What would help me is to find a soldering iron with a short tip. I have a Weller 25 wa...

Are there any guidelines for soldering 18g leads to Phosphor-Bronze? I assume that I should rough the Phosphor-Bronze up with some fine sand paper before soldering the wires to it, but I'm still concerned about the connection being. (I'm using Phosphor-Bronze for it's flexibility and electrical conductivity). Thanks. Darren Harris Staten Island, New York.

Hello all, I've only done a little soldering before, but I want to rebuild a battery pack for my TI-59 calculator (which is basically 3 AA-sized batteries soldered together in series). Can I just solder directly onto the battery terminals? With a copper wire. Should I use flux? Will this overheat the battery and/or blow it up? Thanks for any tips!

So, I've learned the hard way that it isn't trivial to solder a LED matrix. I've actually extended that lesson to realize any non-planar graph adds difficulty to soldering. Anyway. I was trying to build a 5x5 LED matrix (because I only have 25 LEDs right now, and it seemed like a good start). I got two rows in, before I realized I wasn't going to be able to finish it the way I was t...

What do hobbyists do if the IC they want is only available in a tiny 5mm-on-a-side format, like CLCC? (I'm thinking, specifically, of an accelerometer made by Analog Devices.) Are there snap-in adapters out there that would give me a more PDIP-like pin-out? I have seen suggestions, on sci.electronics.design, for how to solder the tiny buggers, but the implied soldering skill level seems wa...

I have to solder 550 - 600m of 1mm copper wire. Wire must be completely covered with solder. It will take some time to do this on regular basis ( with soldering iron ) so i was thinking to make some kind of slot in some aluminium housing and melt the lead alloy in it. Then i can put the wire in it and draw it slowly throe this slot. Additionally i can set some stepper motor on the othe...

Does anyone know if soldering copper wire to Phosphor-Bronze make a solid and reliable electrical connection? Would it make much of a difference if the copper wire is stranded or solid? If there is a better wire material for this or any problems I should watch out for I'd appreciate it. (I'm only concerned about getting the best permanent connection possible). Thanks.

Applying 5V to the inputs (power supply is also 5V), I'm only getting 0.6V at the outputs. I thought it was a faulty chip, or perhaps damaged while soldering, but I've tried another one in a holder and got the same result. What could be causing this?

I'm a writer, and although I keep telling myself I'm still an electronics amateur, I haven't actually touched a soldering iron in years. I hope you'll help me anyway. :) Partway into a story, I've hit a snag because I'm not positive a necessary 'prop' can be made. This problem is therefore theoretical in that I won't actually build it, but my internal editor demands that it could be buil...

Are Circuit Pen's as useful as they sound? I'd like to create my own circuit boards. Since I'm just learning and only doing one-offs, I'd prefer to keep the total cost down. Are they "good enough" to do full circuit boards, or are they mostly for repairs? Are there brands that are a better value than others? How well does soldering on them work? Are they typically fine enough for SM...

I have a plain 30-watt pencil iron. It's this one: https://www.amazon.com/gp/product/B00KXX6RLA/ The tip is almost 3 inches long, and when fully inserted only about 3/4 inch protrudes out of the barrel. The 3 inches also corresponds to the portion of the barrel that has become darkened over time, which I assume indicates that's where it heats up. Would it be possible to pull the t...
