Re: ok,, New Project time,,,

I think I'd use a manual lookup table by reading a voltmeter and then seeing the corresponding figure on a chart. I pretty much did that when I used to measure outdoor temperature before digital thermometers became lower cost.

Re: Soldering iron tip woes

I used to have a low power iron that I would slip into a layered foil sleeve to make it hot. That gave me the idea the of opposite of clipping a temperature controlled one onto a heatsink that can dissipate more than the maximum output of the heater.

Re: Having a problem with a triac

That's similar to what I put in a circuit when repairing an antique SCR based vehicle battery charger.

Re: Soldering iron tip woes

The idle switch inserts or removes a diode rectifier in series with the heating element. I think that it cuts the AC voltage going to the heater in half.

Re: What kind of dye is this?

An idea I have is that It's paint pigments that match what car manufacturers use.

Re: Soldering iron tip woes

I can't knock that since my soldering irons have been those low cost ones with the tip held in by set screws. My tips are 6 gauge copper wire. When the tips get deeply pitted I can cut new ends onto them.

Re: Soldering iron tip woes

I have a switch that lets my soldering iron idle at a lower temperature. It helped a lot to keep the tips from going bad as fast.

Re: Technology Backfire?

I did what Haklesup did but attached a little 12.6V charger to the antenna on a 2000 Explorer. It will unplug if I forget to myself. I like that idea of the ammeter connection across the battery disconnect switch. I would expect those Honda batteries under those types of drain/charge conditions to d...

Re: Ham License

I was helped getting my ham license by how they had recently opened up the technician license category when I took an entry exam.

Re: Beheaded fatty nail as soldering tip...

Hi Mr Al, sorry if I missed replying to something. If you like to send it again I can still try to answer it. I remember now about the diamond things. The little hand files came from Dollar Tree, four in the pack. I also got packs of diamond cutting wheels for my Dremel rotary tool from Harbor Freig...

Re: Beheaded fatty nail as soldering tivp...

Howdy Mr Al, thanks for mentioning maybe missing a PM. That wasn't any problem considering how things can happen in life.

I had some of those files that came four in a pack. I think they indeed were pretty low quality.

Re: Beheaded fatty nail as soldering tip...

haklesup, those thoughts remind me how diamond fingernail files deteriorated much faster than I expected when filing steel nails or black drywall type screws, as far as I can remember.

Re: Beheaded fatty nail as soldering tip...

Reminds me of when cutting steel with a diamond impregnated circular saw blade. The diamond tends to dissolve.

Re: Beheaded fatty nail as soldering tip...

Indeed! You're welcome.

I inserted a rectifier and switch into the cord, so that through the diode is low, and bypassed is high.
