Relays Run This Balanced Ternary Adder
If you’re at all familiar with digital computing, you’ll know that computers represent everything in binary values of one and zero. Except that’s not technically the only way to do computing! You can use any numerical system you like if you build your hardware to suit, as [Jeroen Brinkman’s] ternary adder demonstrates.
As you might guess from the prefix, “ternary” refers to a base-3 numerical system. In this case, [Jeroen] implemented a balanced ternary system, which effectively uses values of -, 0, and + instead of just 1 and 0. The adder is built using relay logic, and is designed to handle 4 trits—the ternary equivalent of bits, where each trit can have one of the three aforementioned states. On a hardware level, trit states are represented with voltages of -5, 0, or 5 V in this case, and are handled with special tri-state switching elements that [Jeroen] constructed out of simple SPDT relays.
[Jeroen]’s write-up does a great job of explaining both ternary basics as well as the functioning of the adder. It’s also quite intuitive because it’s possible to see the relays clicking away and the LEDs flashing on and off as the circuit does its work to add values stored in ternary format.
If you’re trying to get your head around ternary computing from the very lowest level, this project is a great place to start. We’ve seen base 3 hardware built before, too—like this simple ternary computer lashed together from accessible components.
If you’re cooking up your own computing apparatus that uses some weird number system or something, remember—we’d love to hear about it on the tipsline!

@afewbugs ouch. It's one of those situations where any move is going to cause a little bit of pain. There would probably have been a diplomatic way to “guide” future cake baking towards more appreciated flavor, but it's very hard to come forward and say what one prefers unless they are being asked, especially if what's being given is a gift.

Credevo fossi varesina! Mezzo metro di neve? Dove? 😃

@afewbugs 🫂 any time you do need any chocolate cake eaten, I'm here for it... er, you... here for you
I prefer coffee cake, but I fear that speaks to other addictions of mine 😇

But yeah, not sure where I was going with this and it's probably more something to unpack in therapy than share on the internet honestly, but thank you to the people who ask what people want before cooking for them. And we should probably all be doing that a bit more, and I should probably do more work on feeling I can express what I want without feeling I'm hurting people by doing so. Also it's okay not to like something everyone else loves, whether that's chocolate cake or birthday presents

@afewbugs There's nothing self-indulgent about that; it sounds like you spent many years indulging other peoples' fantasies about what you should and shouldn't like. And, sorry to say, that experience is also familiar to me, too.
I hope you treat yourself to non-chocolate confectionary nowadays :)

@lolgop Don't call them abortion pills, call the Period(or menstruation) regulation tablets They do prevent irregular periods due to pregnancy, just do not say that bit out load.
