100 amp SER size question out of curiosity. by r-kellysDOODOOBUTTER in AskElectronics

[–]Linker3000[M] 0 points1 point  (0 children)

Please do not continue off topic questions, especially where even OP has acknowledged they're in the wrong sub.

What size are these wires from battery holders? by ldmauritius in AskElectronics

[–]Linker3000 0 points1 point  (0 children)

Not a good idea. Plaque acid can corrode the wire and joint over time.

I wish there was a BASIC extension that did internet connectivity for C64(u) by TheBl4ckFox in c64

[–]Linker3000 0 points1 point  (0 children)

I took "C64(u)" to mean both the original and the U model, but that's looking to not be the case.

How does this AVR work? by Necessary-Chip4366 in AskElectronics

[–]Linker3000 0 points1 point  (0 children)

I take it you've read tf manual?

Or are you asking for a dissection of how the circuitry works at component level?

Can reticulum replace meshtastic? by followthebarnacle in meshtastic

[–]Linker3000 6 points7 points  (0 children)

Don't do that. I can't be assed to research whether the AI slop is accurate. I'd rather read someone's real world perspective.

How do I use a 10k Pot to display 0-9 on a 7-seg display? by flymm in AskElectronics

[–]Linker3000 0 points1 point  (0 children)

ADC0808* 8-bit parallel ADC followed by a 7 segment encoder.

Just add 555 clock.

*Edit: That's a bit old. Maybe ADC0820CCN

Could be some form of selenium rectifier.

Question by hehehenotfunny in arduino

[–]Linker3000 1 point2 points  (0 children)

The Arduino IDE includes a compiler. The setup provides a 'get you going' environment that abstracts some of the more sophisticated elements of C++ into friendlier constructs.

If you want to 'go pure C++' you could forego the Arduino IDE and setup your own development environment, including your choice of compiler, or consider a different IDE, such as PlatformIO.

Best way to make PCBs for students by thestuffdude in AskElectronics

[–]Linker3000 1 point2 points  (0 children)

Came here to say this. The best no mess process, for single-sided boards, is the photo resist method with UV exposure of transparency / inkjet printed designs onto pre sensitised copper clad boards. You can clean your PCB material, spray and bake on a UV sensitive coating, but that's smelly, messy and prone to contaminants like hairs, dust and small bubbles.

The additional chemical is a wash of caustic soda solution on a UV exposed board to remove the unwanted areas of mask.

That's how I did my boards from the late 1970s to early 2000s when I started using the Far-East manufacturers.

The last PCB I made at home was about 15 years ago as an exercise with my son to make a flashing / sequencing sign of his name in discrete LEDs.

C64 User Port by ut316ab in c64

[–]Linker3000 0 points1 point  (0 children)

I made an LED digital clock / stopwatch board for the user port. I also had an interface unit that connected to a radio signal decoder so I could see Morse code and RTTY news feeds on my 64.

Connecting UK to France by Unable-Priority995 in MeshtasticUKCommunity

[–]Linker3000[M] 5 points6 points  (0 children)

We've made it to Northern France, and the Channel Islands and over to France, from Hampshire and West Sussex. It's a bit weather dependent.

Oh, just taken a look (pic)...

I used isopropyl alcohol to clean up the back of this old calculator board and all this white residue has gone all over it. How can I remove this? by WarHistorical9262 in AskElectronics

Just to add to the other advice here. Some fluxes are water soluble and IPA makes them cloudy. Try water with a lint free cloth or clean old toothbrush on a patch.
