Hm.

Another perennial debate as an #electronics and #electricalengineering hobbyist:

Do I buy only as many units as I need for this one project I'm working on now?

Or do I buy enough to get the next price breakpoint and have spares for future projects I have not yet planned?

🤔

(I need at least three of these, preferably five to feel comfortable futzing around with 'em, but buying ten would cost only $8.50 more than that: digikey.com/en/products/detail )

My mid-level analog skills have always been a bit shit. It took me a while to dig up the "proper" way to be able to duty-cycle a voltage divider so that it doesn't (constantly) contribute to quiescent current when monitoring a battery. It's not terribly hard to find a combination n-fet and p-fet in one package to reduce the footprint. If you know of something even simpler I'd love to see it. electronics.stackexchange.com/

An alternative approach that I can think of is discrete implementation of CMOS buffer/inverter using power MOSFETs which might be easier for me to search for good P/Ns.

Alrighty, I need to post an RFC to the #electronics and #electricalengineering fedi mind hive:

I am searching for a method to inject a clock signal (f≤1Hz) into a power supply by swapping the +V/0V rails back and forth.

Requirements:
- Able to operate at up to +12V
- Single-rail supply
- Min. TDP: 1W

Update:

I figured out a solution based around cheap parts that will be more than adequate! Thanks for the feedback! 😄

At least I now know that what I'm designing is a bunch of giant, wall-mounted, concentric ✨ ring counters ✨ to be implemented using discrete components.

That's knowledge I can carry forward to more effectively find solutions, and I may have actually already found one I can already use, but alas it must wait until the work day ends.

Update!

@MeiLin gave me the search engine shibboleth I needed to find this web page with a lovely and clever transistor circuit that I can try out!

It's even simple enough for me to try to breadboard it!

Edit:
... Oh wait this emulated schockley diode circuit requires obscene voltages in order to exceed the avalanche breakdown Vec. I uh... can't use that. I'll need to find other solutions. :x

This circuit would be so much easier to implement if I would just let myself use J/K flip-flops, but:

1. the only cheap ones available are duals in 16-pin packages when I only need one per ring node and each ring node is an independent pcb, and

2. I very explicitly decided that the light at each node MUST be surrounded by a curious cloud of discrete components for the sake of art 😤

Oh gods, I'm gonna have to find resources to study up about resistor-transistor, diode-transistor, and transistor-transistor logic, if I want to be able to implement the round-robin circuit for the Horologium Keplerus using discrete transistors. >.>;;

I guess RFC for links to resources if anybody has useful links that can cut through the less than optimal search engine algorithms that almost only return SEO'd blogs that have no meaningful information?

I am *very* temptedly considering something extremely cursed:

Abusing an "ultra thin" ethernet cable to bring +12V+GND to a control box that needs only a few mA max, and 3x 5V differential signals back out to the thing being controlled.

"ultra thin" ethernet cables typically use 30AWG conductors which have a max power transmission ampacity of ~142mA, way more than enough to power the control box.

I'm pretty certain the insulation inside can handle 12V. 🤔

Hey everyone! I've made the jump from Mastodon.Social and wanted to introduce myself. I'm an electrical engineer living in the southeastern USA.

You'll find me tooting about Linux, FOSS, Python, and scripting. When I'm not on the keyboard, I'm into photography, hiking, and enjoying nature with my spouse.

Also, I have two black cats that pay rent with their winning personalities and love. lol :rickdance:

Looking forward to connecting in this community! Don't hesitate to say hello.

*takes a BIG hit of the Magic Blue Smoke Hookah* It's all just the field, maaaaaaan. ⚡🌿

Our arcane constructs, twisting, branching paths of metal and semi-metal, manipulate the electromagnetic field into the useful shapes we want it to take.

And electrons being the mobile charged particles they are simply react to that field, and the ways they react to that field are the effects that we observe.

It's allll just the field~ ⚡🌿
